Environment.getExternalStorageDirectory() deprecated in API level 29 java

Use getExternalFilesDir(), getExternalCacheDir(), or getExternalMediaDirs() (methods on Context) instead of Environment.getExternalStorageDirectory().

Or, modify mPhotoEditor to be able to work with a Uri, then:

  • Use ACTION_CREATE_DOCUMENT to get a Uri to a location of the user's choosing, or

  • Use MediaStore, ContentResolver, and insert() to get a Uri for a particular type of media (e.g., an image) — see this sample app that demonstrates doing this for downloading MP4 videos from a Web site

Also, note that your Uri.fromFile with ACTION_MEDIA_SCANNER_SCAN_FILE should be crashing on Android 7.0+ with a FileUriExposedException. On Android Q, only the MediaStore/insert() option will get your content indexed by the MediaStore quickly.

Note that you can opt out of these "scoped storage" changes on Android 10 and 11, if your targetSdkVersion is below 30, using android:requestLegacyExternalStorage="true" in the <application> element of the manifest. This is not a long-term solution, as your targetSdkVersion will need to be 30 or higher sometime in 2021 if you are distributing your app through the Play Store (and perhaps elsewhere).

Get the destPath with the new API call:

String destPath = mContext.getExternalFilesDir(null).getAbsolutePath();
