About Target SDK 30, Storage Permissions, and requestLegacyExternalStorage

  • It notifies those apps which set requestLegacyExternalStorage=true, but it didn’t verify those apps go against Scoped Storage.
  • After May 5th, for the app with targetSDKVersion of API 30, it must be modified to use Storage Access Framework or Media Store API, declare why they need MANAGE_EXTERNAL_STORAGE, or remove MANAGE_EXTERNAL_STORAGE.
  1. for those features of creating files or getting images … etc, we refer https://developer.android.com/guide/topics/data and change using Storage Access Framework or Media Store API.
  2. Keep requestLegacyExternalStorage=true. Though it will be ignored for those apps with targetSDKVersion of API 30 running on devices of Android 11, this flag guarantees our apps work as previously behaviors under Android 10.
  3. Except for file managers, etc, other apps shouldn’t include MANAGE_EXTERNAL_STORAGE, so remove it.
  4. The WRITE_EXTERNAL_STORAGE is also ignored on Android 11, and we prefer keeping requestLegacyExternalStorage=true, so we modify our permission declaration to
android:maxSdkVersion="29" />
  1. runs Android 9 or lower,
  2. temporarily opted out of scoped storage (this means <application android:requestLegacyExternalStorage="true" ... >
