I'm trying to get a Device Policy Manager to work, but i get stuck when i try to enable it. Googled a lot and already getting agressive about that error:

any help or advice would be much appreciated!
Check your receiver name <receiver android:name="MyDeviceAdminReceiver"
I think you forgotten to add . before the receiver name:
<receiver android:name=".MyDeviceAdminReceiver"
I think if you recheck your DeviceAdmin java file the receiver name you are trying to extend is different than the one you are specifying in the android manifest.xml file. Just a wild guess as you have not shown your DeviveAdmin java file
I have been struggling with this issue for the last day... Just came across my own issue. My issue was in my componentName
I was doing my constructor such as:
val adminName = ComponentName(this, ::DeviceAdminReceiver.javaClass)
and finally noticed I was receiving a Warning about Public constructors
PackageManager.NameNotFoundException... A quick shift to
val adminName = ComponentName("com.project.myApp", "com.project.myApp.DeviceAdminReceiver")
and everything worked immediately.

I tried custom activity defining directly into menifest but its not work. please help me I'm newbie
You can try AudioServiceFragmentActivity instead of AudioServiceActivity. More information about the different ways to define an audio service activity can be found in the audio_service documentation.
I'm rebooting the phone and I expect a log message. I've registered the BroadcastReceiver in Androidmanifest, but no message is being received. What am I Missing?
androidmanifest:

When I filter in the logging for "boot" I see several other apps logging the event, but not my own App:

The code above is working fine.
I have checked on device ->

Try changing your device and test.

activity?.applicationContext?.bindService(
intent, this, Context.BIND_AUTO_CREATE

}
}
I am not sure what is causing this warning, and I have tried out different solutions after searching on stackoverflow and google.
How do I test is:
Launch my server application
Launch my client application
I see the warning
Thank you for taking the time to read my question.
After recent changes, You can use <queries> <package android:name ="your package name" /> </queries>

I did more searching and finally found the answer... All credits go to the SO answer here:
https://stackoverflow.com/a/55712326/3718584
TLDR:
Had to change the intent from implicit to explicit due to API 21
intent.setClassName("com.rchan.nveeapplication","com.rchan.nvee_sdk.detectedactivity.DetectedActivityService")
We have been working on the integration between worklight and xtify for push notifications. We are using version 2.3.2 for xtify sdk since latest version (2.4.2) made the app failed because a class not found exception.
The logic for using xtify has been added to the native code of the WL hybrid application as follows:
public class XtifyWL extends WLDroidGap {
public static final String XTIFY_APP_KEY = "xxxxxxxx-xxxxx-xxxx-xxxxx-xxxxxxxxx";
public static final String PROJECT_NUM = "xxxxxxxxxxxx"; // This is the Google Project Number
#Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
XtifySDK.start(getApplicationContext(), XTIFY_APP_KEY, PROJECT_NUM);
}
We are receiving the push notifications, but they are duplicated. We received one notification for worklight that fails when you try to open it, and one more for the native application thats works correctly.
How can we fix it?
About the issue with the SDK 2.4.2.2
The exception with SDK 2.4.2.2 is:

The only place where we see that class is in the AndroidManifest.xml
<provider android:name="com.xtify.sdk.db.Provider" android:authorities="com.XtifyApp.XTIFY_PROVIDER" android:exported="false" />
If we comment that line it fails with the next use of any class of the SDK. We have added the sdk .jar file to the libs folder of the android project and to the build path of the android project.
Thanks,
We have found why when we send a push notification, we see them duplicated (two notifications icons on the top).
It was an error in the AndroidManifest.xml, we added all the Xtify GCM configuration and we also left the worklight GCM configuration so we where registering two receivers.
But we have still the issue of "java.lang.ClassNotFoundException" when we try to use the latest Xtify SDK. Athough at least receiving simple notifications seems to work with the SDK 2.3.2.

I really do not know what is wrong, but my if widget is update by system by "APPWIDGET_UPDATE" it throws following exception. I tried several things, exporting receiver (true/false), I tried it on emulators and real phones, but it is same. I added several intent-filters, but it did not work.

My AppWidgetProvider is only declared, because I tried to eliminate possibilities, but the exception is throw before ExchangeRateWidgetProvider.onReceive() is called.

I appreciate if you can take a look ...
Your problem lies somewhere in your Java code, where you are attempting to send the android.appwidget.action.APPWIDGET_UPDATE broadcast. That is to be broadcast by the OS, not by apps, and that is what the Permission Denial is about.
