android java: google admob policy collected data checklist

 

In May 2021, Google Play announced the new Data safety section https://developers.google.com/admob/android/privacy/play-data-disclosure. All application must declare data safety, include if application has 3rd partly like Google Google Mobile Ads.

Unfortunately, the guidance data disclosure in https://developers.google.com/admob/android/privacy/play-data-disclosure does not clear. It does mention clues what Google Mobile Ads SDK do with our client data. Here are the clues:

Data

By default, the Google Mobile Ads SDK...

IP address

Collects device's IP address, which may be used to estimate the general location of a device.

User product interactions

Collects user product interactions and interaction information, including app launch, taps, and video views.

Diagnostic information

Collects information related to the performance of your app and the SDK, including crash logs, app launch time, hang rate, and energy usage.

Device and Account identifiers

Collects Android advertising (ad) ID, app set ID, and, if applicable, other identifiers related to signed-in accounts on the device.

We must fill in Data safety section:

Android java: request multiple permission READ_EXTERNAL_STORAGE & WRITE_EXTERNAL_STORAGE

Minimum API 24 (Android 7.0) 

Note:

  • Beginning with Android 4.4 (API level 19) it's no longer necessary for your app to request the WRITE_EXTERNAL_STORAGE permission to write to its own application-specific directories on external storage, which are provided by getExternalFilesDir(). However, the permission is required for API level 18 and lower. Example:
    File extDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
  • If the permission is a runtime permission or special permission, and if your app is installed on a device that runs Android 6.0 (API level 23) or higher, you must request the runtime permission or special permission yourself.
  • On devices that run Android 4.4 (API level 19) and higher, your app can interact with a documents provider, including external storage volumes and cloud-based storage, using the Storage Access Framework. This framework allows users to interact with a system picker to choose a documents provider and select specific documents and other files for your app to create, open, or modify.
  • To support media file access on devices that run Android 9 (API level 28) or lower, declare the READ_EXTERNAL_STORAGE permission and set the maxSdkVersion to 28. See reference 1.
  • If your app targets Android 10 (API level 29) or lower, you can temporarily opt out of scoped storage in your production app. If you target Android 10, however, you need to set the value of requestLegacyExternalStorage to true in your app's manifest file.

AndroidManifest.xml

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"
        android:maxSdkVersion="28"
