I want to display the current bucket of my application with a device under Android P beta. Therefore, I try to use the UsageStatsManager class like this :

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if (Build.VERSION.SDK_INT >= 28) {
        UsageStatsManager usageStatsManager = (UsageStatsManager) getSystemService(USAGE_STATS_SERVICE);
        if (usageStatsManager != null) {
            Log.d(TAG, "getAppStandbyBucket():" + usageStatsManager.getAppStandbyBucket()); 
My Manifest possesses the permission android.permission.PACKAGE_USAGE_STATS :
<uses-permission 
    android:name="android.permission.PACKAGE_USAGE_STATS" 
    tools:ignore="ProtectedPermissions" />
But I encounter a crash when I launch my application :
07-24 10:23:39.061 26967-26967/com.app.bucket E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.app.bucket, PID: 26967

It seems that I missed a permission, but even when I add the following permission :
  <uses-permission
        android:name="android.permission.INTERACT_ACROSS_USERS"
        tools:ignore="ProtectedPermissions" />
I still have the same crash. I was thinking that maybe I miss the runtime call for the permission, but like the documentation stipulate :
  
NOTE: Most methods on this API require the permission
  android.permission.PACKAGE_USAGE_STATS. However, declaring the
  permission implies intention to use the API and the user of the device
  still needs to grant permission through the Settings application. See
  Settings.ACTION_USAGE_ACCESS_SETTINGS. Methods which only return the
  information for the calling package do not require this permission.
  E.g. getAppStandbyBucket() and queryEventsForSelf(long, long).
It's not necessary. Even knowing that I tried to use the runtime permission, but I still get the crash. If anyone see what is missing, I would really appreciate the help. 
                I was wondering, if it could be a bug... I wanted to check before reporting an issue, if I was missing something. Thanks for your answer, I will keep updated this question as soon as the bug will be fixed.

                It looks like it was fixed according to the latest comment in that link.  "The issue has been fixed and it will become be available in a future Android release. Please keep an eye on the release notes."  That was back in 2018.
