To delete multiple markers at once, you can use the organizer (see the "organizer" section from this help page)

Using the organizer

You can open the organizer by clicking the organize button from the top bar of the main page.
The organizer will allow you to perform actions on multiple markers at once, or on multiple folders at once.

At the top of the screenshot below, the visible buttons are:

  • Select all button: select all the elements in the list
  • Organize POIs / Organize Folders switch button: switch between organising POIs or Folders

When organizing POIs, with at least one POI selected, the following buttons will become visible:

When organizing Folders, with at least one Folder selected, the following buttons will become visible:
  • Move to folder button: move the selected Folders to another folder
  • Copy to folder button: move the selected Folders to another folder
  • Delete button: delete the selected Folders

Using map folders

You can use map folders to organize your markers into different sections. Things you can do with folders:

  • create a folder
  • ‎edit a folder
  • ‎marker templates: custom fields
  • ‎mass assign color
  • ‎mass assign custom fields

Create a folder

To create a folder:

  1. open the sidebar
  2. ‎click "Add folder"
  3. ‎enter the desired folder information
  4. ‎click ok to save the new folder

Edit a folder

To edit a folder:

  1. open the sidebar
  2. ‎long press on the folder you wish to edit
  3. ‎modify the folder to your liking
  4. ‎click ok to save the changes

Marker templates: custom fields

While creating or editing a folder, you can define custom fields into the folder. Those folder custom fields will act as a template: when creating a new marker with only one folder selected, if that folder has custom fields then the folder's custom fields will automatically be added to the newly created marker.

To create a folder's custom fields from the folder create/edit page:

  1. click "more options"
  2. ‎select "add custom field"
  3. ‎edit the custom field to your liking and save it

To edit a folder's custom fields from the folder create/edit page:

  1. click on the custom field from the custom fields list
  2. ‎edit the custom field to your liking and save it

Mass assign color and custom fields

When changing a folder’s color or custom fields, a prompt will offer you to mass-assign the color or custom fields to the markers inside that folder.

Presets, templates and bulk icons with folders

If you want markers to be automatically created with a specific combination of icon, color and custom fields you can achieve this through folders. Folders will act as templates for their children markers. To do this:

  1. Create a folder
  2. Choose the icon, color and custom fields that you would like to see by default for new markers
  3. Save the folder
  4. Double click on the folder from the main menu to select only that folder
  5. And any new marker that you create will inherit its parent folder’s attributes

Migrating your data to a new device

If you lost your device or did a factory reset or simply got a new device, you might need to migrate your previous markers data to this new device. Depending on your case, there are several ways to do this...

Case 1: You were using the premium cloud sync on your previous device

⇒ Simply open the existing cloud map by following the instructions in this section: How to open an existing map file from the cloud?

Case 2: You were not using the cloud sync, but you saved your markers into a file with the export feature

⇒ To import your markers into the new device, follow the instructions in this section: Importing and exporting markers

Case 3: You created no backup but you still have access to the previous device's data

⇒ You will need to export the markers data from your previous device, and then import your markers data into your new device. For more information on how to export and import data, see the following section: Importing and exporting markers

Case 4: You created no backup and you do not have access to your previous device's data

⇒ If your previous device had Android 6 or up installed, it might have backed up some app data automatically through Google Drive, depending on your settings at the time. Upon installing the app on your new device, the data might be restored automatically. If that's not the case, there is no other way to retrieve the data to my knowledge :'(

Advanced features

Configuring third party search sources

You can add or configure third party search sources in Map Marker from the "Places search sources" section menu.

Once you have obtained a third party search source configuration, you can re-use this same configuration on any device running Map Marker.

To use a configuration, from the search source menu in Map Marker:

  1. Click "Add or configure search source"
  2. Click on the search source that you want to add/configure
  3. Enter/paste the requested configuration values
  4. Check the displayed result (success/failure)

Below are the different third party sources that can be configured with instructions on how to obtain the configuration values, by increasing order of difficulty. Microsoft Bing Places Search seems like the best option because it's easy to setup and the search result quality is pretty good.

Bing Places Search API (very easy)

Notes:

  • You will need to use or create a free microsoft account to retrieve the configuration values
  • There is no need for a credit card
  • The free quota is plenty for a single user
  • The configuration value you will need to obtain is a Bing Places API Key

Steps:

  1. Follow the instructions here: https://docs.microsoft.com/en-us/bingmaps/getting-started/bing-maps-dev-center-help/getting-a-bing-maps-key
  2. Use the following key type: "Bing Maps Keys for Business and Personal Use"
  3. Use the following application type: "Website"
  4. You can then create/retrieve the key from here: https://www.bingmapsportal.com/Application under "My Account" > "My Keys"
"Google" Places Search API (very hard)

Notes:

  • !!!FOR ADVANCED USERS ONLY!!!
  • You will need to use or create a free Google account to retrieve the configuration values
  • The free quota should be enough for a single user
  • The configuration value you will need to obtain is the API key
  • To get a functional API key, you will need to give your credit card information to Google
  • Google may charge you on the API usage
  • There are ways to limit the usage to only the free quota, to avoid being charged, but they depend on your configuration
  • It is impossible to use the free quota without providing a credit card
  • It is impossible to guarantee no expenses due to an accidental bad configuration
  • I will not provide support for this, you will have to interact with Google directly: https://developers.google.com/places/web-service/support

Steps:

  1. Get an API key here: https://developers.google.com/places/web-service/get-api-key
  2. Enable billing for your google cloud console account
  3. Set a limit on your Places API usage
  4. Save the API key in a way that you can paste it into Map Marker

How to use offline maps?

  4. Scroll to the bottom
  5. Click "Next"
  6. Select a convenient way for you get the files and click "Create archive"
  7. Click "Download" to download the created archive
  8. Unzip the archive file and retrieve the file named "Saved Places.json"
  9. Convert the file to KMZ with this page: https://mygeodata.cloud/converter/
  10. Import the resulting KMZ file into Map Marker

Important note: This only works for starred locations, not other lists. Unfortunately, at the moment, it seems Google does not provide a way to export those.

How can I extract POI images from Map Marker?

If you want to extract POI images from Map Marker, there are several ways you can go about this.

Image extraction - Method 1: the KMZ export

  1. Find out how to change a file extension on your system (Linux / Windows / MacOS / etc.): if you don't know how to do this, search for "How to change a file extention in Linux/Windows/MacOS/WhatEverYourSystemIs" in your favorite search engine
  2. Export your map as a KMZ file
  3. Change the KMZ file extension from .kmz to .zip
  4. Extract the zip file with a zip files manager
  5. Image files will be in the extracted "local_media" and "cloud_media" folders, without extensions
  6. Depending on your system, for the system to detect and open these files as images, you might have to change the extension of image files as well to ".jpg" or ".jpg"

Image extraction - Method 2: the premium cloud sync (paid)

  1. Sync your map file to the cloud with the premium cloud sync
  2. Open the map file menu by clicking at the top of the left drawer menu
  3. Click "Share cloud map" to open the Google Drive folder of the cloud map
  4. Filter the view to only see image files, they should all be there

Image extraction - Method 3: the image share feature

When viewing an image from the app, you can share it externally by clicking the "share" button at the top right. However you can only extract images one by one that way.

  1. Open the image from within the app
  2. Click the share button at the top right

FAQ

What is the premium upgrade?

The Map Marker lifetime premium upgrade for the Android app grants you lifetime access to the Map Marker premium on an unlimited number of Android devices.
The premium grants you access to:

  • Cloud sync with Google Drive or Dropbox
  • Cloud map collaboration with other premium users
  • Map versions history with restore ability

I want to try early features, how can I use the beta?

If you're impatient to test new upcoming features and you are not afraid to encounter bugs in the app, you can join the beta.
Note that it is HIGHLY RECOMMENDED that you know how to save/restore your markers via the manual export/import or the cloud sync BEFORE joining the beta.
Also note that if I'm not working on any special feature, the beta might not have anything different from the production app.
With all that being noted, you can join the beta here:

https://play.google.com/apps/testing/com.exlyo.mapmarker

How can I help with translations?

Follow the instructions on the github page for translations: https://github.com/androidseb/mapmarkerapptranslations

I have a feature idea, how should I submit the idea?

First you should take a look at the Map Marker roadmap to see if the idea is not already there:

http://mapmarkerapp.com/wip.html

Then if the idea is not already submitted, you can send me an email and I’ll check it out :-)

How can I stay tuned about what’s coming soon for Map Marker?

If you want to know what’s coming next you can check this page:

http://mapmarkerapp.com/wip.html

If you want to be notified when new features come out, follow me on twitter:

https://twitter.com/mapmarkerapp

Why is Map Marker not a navigation app?

Navigation apps are complex and hard to get right, and there are already a lot of good navigation apps out there. I believe that as a single developer, the way I can provide most value with Map Marker is by focusing on the ability to organize your places, and have an easy way to start navigation into navigation-focused apps. Map Marker’s focus is different from navigation.

How do I add locations on Google Maps?

Map Marker does not provide such features. Instead, try using one of those links:

A place in Google Maps has wrong/inaccurate data, how do I fix it?

Map Marker does not interact with Google Maps data, instead, try using the Google platform:

  • go on Google Maps from a desktop computer:
  • click the location that needs fixing
  • click "suggest an edit"

How to install the old map marker app

If you need to switch back to the old Map Marker V2, you can install it from the APK file available here: https://github.com/androidseb/mapmarker/releases/tag/map_marker_v2.
Note: if you updated from Map Marker V2 to Map Marker V3 without uninstalling the app, re-installing the app like this over Map Marker V3 will switch you back to the old Map Marker V2 without losing your user data. However any data created from the V3 app will not be accessible from the newly installed V2 app.

Where can I find the help center for Map Marker V2?

If you are using the legacy Map Marker V2 app version, you can find the help center archive here.

Troubleshooting and known problems

Cloud sync error: 404 file not found

When performing cloud sync, this error can occur if some remote cloud files have been deleted.
This can happen if you (or one of your collaborators if you're sharing access) have deleted the cloud files from your cloud storage account.
When this error happens, you can no longer sync to the cloud map and it also probably means that the only copy of your data is on your device, since the cloud data is gone.
The recommended way to proceed in case you encounter this error is the following:

  1. Export your markers as a KMZ file
  2. To minimize the risks of losing the data, create a copy of that exported file somewhere like a secondary device, or a cloud storage account
  3. By default, Map Marker creates a dedicated folder in your cloud storage account called "Map Marker Places Organizer": identify the source of the cloud data deletion so that it doesn't happen again, for example, if one of your collaborators deleted some file accidentally (e.g. "accidental cleanup"), explain them why not deleting these files is important
  4. Create a new cloud map
  5. Import the data from the KMZ file
  6. Sync your cloud map

GPS location inaccurate

On some Android devices, it can happen that the GPS location becomes inaccurate over time. In some cases, it's even possible to see a correct accurate location in one app and a completely inaccurate location in another app. This is due to the way location tracking works at the system level and can sometimes be resolved by restarting your device. Note that only restarting your device can be insufficient, as some components like the GPS chip might not have been fully powered off in the process. The following steps can often work to resolve the issue:

  1. Power off your device completely
  2. Wait for 10 seconds
  3. Power your device back on

Problems with Google My Maps

Google My Maps cannot import the KML/KMZ files produced by Map Marker if they contain the default folder, because it cannot handle an empty folder name. To work around this, you will need to import only one folder at a time, that is not the default folder.

Premium troubleshooting

When you purchase the premium, it becomes available for life for your Google account. The Google account granted with the premium access is the one used to perform the purchase. Upon purchasing the premium, you will receive a confirmation email with an order number. From then on, you can use the premium on as many devices as you want. However you will need to use the exact same Google account to perform the installation of Map Marker on your other device.

If you cannot use the premium:

  1. Backup your markers outside of the app
  2. Un-install the app
  3. ‎Open the Google play app
  4. Make sure you are signed in with your Google account owning the premium in the left drawer of the Google Play app
  5. Download and install Map Marker again

If these steps don't work you can send me your order number for confirmation and I will help you.

Problems with Google Play Services

Some problems with the Google Play Services app can cause various issues with Google-related services.
Sometimes, you can fix this by clearing the Google Play Services app data:

  1. Open the system settings
  2. Applications
  3. Google Play Services
  4. Storage
  5. CLEAR STORAGE
  6. CLEAR ALL DATA

Problems with map display: blank map

Some problems with the Google Maps component can prevent the map display from loading properly, resulting in an empty blank map.
Sometimes you can fix this by clearing the Google Play Services app data.
Unfortunaltey sometimes this will not be enough and you will need to clear the app data completely to resolve the issue. Since clearing the app data will result in all your markers being deleted, you have to careful follow these steps to avoid losing your data:

  1. Export your markers as a KMZ file
  2. Copy the KMZ file to an other device
  3. Confirm you can import back your markers from the KMZ file
  4. Keep the KMZ file in a safe location
  5. ONLY after your markers data is secured, proceed with next steps
  6. Turn on the problematic device
  7. Open the system settings
  8. Applications
  9. Map Marker
  10. Storage
  11. CLEAR STORAGE
  12. CLEAR ALL DATA
  13. Restart the app
  14. Import your markers back from the KMZ file

Problems with blocked internet access

In some cases, even though your device has correct internet access, the system can block internet access to Map Marker, preventing the app from accessing internet, and preventing sync and causing the map not to load. This can be caused by battery savers and/or incorrect system parameters. If that happens, you can try the following steps to troubleshoot:

  • Check for any power-saving / network blocking apps and ensure that Map Marker is allowed to use the network
  • If that doesn't work, reset your network settings:
    1. Open the system settings
    2. Navigate to network settings
    3. Select "Reset network settings"
    4. Restart your device
  • If that doesn't work, back-up your data and re-install the app:
    1. Export your markers
    2. Import your markers back to another device to confirm that the backup worked
    3. Once you're confident your data is safely backed-up, uninstall the app
    4. Restart your device
    5. Install the app again

Presets, templates and bulk icons with folders

If you want markers to be automatically created with a specific combination of icon, color and custom fields you can achieve this through folders. Folders will act as templates for their children markers. To do this:

  1. Create a folder
  2. Choose the icon, color and custom fields that you would like to see by default for new markers
  3. Save the folder
  4. Double click on the folder from the main menu to select only that folder

How can I extract POI images from Map Marker?

If you want to extract POI images from Map Marker, there are several ways you can go about this.

Image extraction - Method 1: the KMZ export

  1. Find out how to change a file extension on your system (Linux / Windows / MacOS / etc.): if you don't know how to do this, search for "How to change a file extention in Linux/Windows/MacOS/WhatEverYourSystemIs" in your favorite search engine
  2. Export your map as a KMZ file
  3. Change the KMZ file extension from .kmz to .zip
  4. Extract the zip file with a zip files manager
  5. Image files will be in the extracted "local_media" and "cloud_media" folders, without extensions
  6. Depending on your system, for the system to detect and open these files as images, you might have to change the extension of image files as well to ".jpg" or ".jpg"

The premium grants you access to:

  • Cloud sync with Google Drive or Dropbox
  • Cloud map collaboration with other premium users
  • Map versions history with restore ability

I want to try early features, how can I use the beta?

If you're impatient to test new upcoming features and you are not afraid to encounter bugs in the app, you can join the beta.
Note that it is HIGHLY RECOMMENDED that you know how to save/restore your markers via the manual export/import or the cloud sync BEFORE joining the beta.
Also note that if I'm not working on any special feature, the beta might not have anything different from the production app.
With all that being noted, you can join the beta here:

https://testflight.apple.com/join/nQWmtq8I

How can I help with translations?

Follow the instructions on the github page for translations: https://github.com/androidseb/mapmarkerapptranslations

I have a feature idea, how should I submit the idea?

First you should take a look at the Map Marker roadmap to see if the idea is not already there:

http://mapmarkerapp.com/wip.html

Then if the idea is not already submitted, you can send me an email and I’ll check it out :-)

Why is Map Marker not a navigation app?

Navigation apps are complex and hard to get right, and there are already a lot of good navigation apps out there. I believe that as a single developer, the way I can provide most value with Map Marker is by focusing on the ability to organize your places, and have an easy way to start navigation into navigation-focused apps. Map Marker’s focus is different from navigation.

How do I add locations on Google Maps?

Map Marker does not provide such features. Instead, try using one of those links:

A place in Google Maps has wrong/inaccurate data, how do I fix it?

Map Marker does not interact with Google Maps data, instead, try using the Google platform:

  • go on Google Maps from a desktop computer:
  • click the location that needs fixing
  • click "suggest an edit"

Where can I find the help center for Map Marker V2?

If you are using the legacy Map Marker V2 app version, you can find the help center archive here.

Troubleshooting and known problems

Cloud sync error: 404 file not found

When performing cloud sync, this error can occur if some remote cloud files have been deleted.
This can happen if you (or one of your collaborators if you're sharing access) have deleted the cloud files from your cloud storage account.
When this error happens, you can no longer sync to the cloud map and it also probably means that the only copy of your data is on your device, since the cloud data is gone.
The recommended way to proceed in case you encounter this error is the following:

  1. Export your markers as a KMZ file
  2. To minimize the risks of losing the data, create a copy of that exported file somewhere like a secondary device, or a cloud storage account
  3. By default, Map Marker creates a dedicated folder in your cloud storage account called "Map Marker Places Organizer": identify the source of the cloud data deletion so that it doesn't happen again, for example, if one of your collaborators deleted some file accidentally (e.g. "accidental cleanup"), explain them why not deleting these files is important
  4. Create a new cloud map
  5. Import the data from the KMZ file
  6. Sync your cloud map

Why is Map Marker not a navigation app?

Navigation apps are complex and hard to get right, and there are already a lot of good navigation apps out there. I believe that as a single developer, the way I can provide most value with Map Marker is by focusing on the ability to organize your places, and have an easy way to start navigation into navigation-focused apps. Map Marker’s focus is different from navigation.

How do I add locations on Google Maps?

Map Marker does not provide such features. Instead, try using one of those links:

A place in Google Maps has wrong/inaccurate data, how do I fix it?

Map Marker does not interact with Google Maps data, instead, try using the Google platform:

  • go on Google Maps from a desktop computer:
  • click the location that needs fixing
  • click "suggest an edit"

Where can I find the help center for Map Marker V2?

If you are using the legacy Map Marker V2 app version, you can find the help center archive here.

Troubleshooting and known problems

Cloud sync error: 404 file not found

When performing cloud sync, this error can occur if some remote cloud files have been deleted.
This can happen if you (or one of your collaborators if you're sharing access) have deleted the cloud files from your cloud storage account.
When this error happens, you can no longer sync to the cloud map and it also probably means that the only copy of your data is on your device, since the cloud data is gone.
The recommended way to proceed in case you encounter this error is the following:

  1. Export your markers as a KMZ file
  2. To minimize the risks of losing the data, create a copy of that exported file somewhere like a secondary device, or a cloud storage account
  3. By default, Map Marker creates a dedicated folder in your cloud storage account called "Map Marker Places Organizer": identify the source of the cloud data deletion so that it doesn't happen again, for example, if one of your collaborators deleted some file accidentally (e.g. "accidental cleanup"), explain them why not deleting these files is important
  4. Create a new cloud map
  5. Import the data from the KMZ file
  6. Sync your cloud map

Various browser issues

Right now, the only officially supported browser is Google Chrome. The app is built with best effort support for other browsers as well without any guarantee.

Images not displaying (white squares instead)

This can happen if your browser has a setting of blocking third-party content. Since images are coming from Google Drive (drive.google.com) instead of mapmarker.app, the browser with third party content blocked might block this, resulting in images displayed as white squares. To fix this on Google Chrome, go to the browser settings and change the settings under "Cookies and other site data" to allow third party cookies on mapmarker.app.
