Check android:allowBackup value programmatically

Question

As I have studied about the security issues in Android, one good practice is to check if the allowBackup and backupAgent has been set in the AndroidManifest.xml.

How to check android:allowBackup value of an app programmatically?

Answer 1

      PackageInfo packageInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
      if ((packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_ALLOW_BACKUP) != 0) {
         // enabled
      } else {
         // disabled
      }
