Please help me if you have any ideas!
*Update:
Levon from Amazon reply for me. ADM can run on physical device (of Amazon or not) but not work :(
same error:
java.lang.NoClassDefFoundError: Failed resolution of: Lcom/amazon/device/messaging/ADM;

I have had the same issue. Problem was in xml namespace in manifest.
It should be like in documentation:
xmlns:amazon="http://schemas.amazon.com/apk/res/android"​

Class Extending FirebaseMessagingService not working inside Android Library

I created an Android Library to implement FCM to use in my internal projects, where I implement a class to extend FirebaseMessagingService (.services.MyFirebaseMessagingService ) and another one to extend FirebaseInstanceIdService (.services.MyFirebaseInstanceIDService).
I defined this in my AndroidManifest.xml inside the library as below:
<!-- [START firebase_service] -->
<service
android:name=".services.MyFirebaseMessagingService"
android:exported="true">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<!-- [END firebase_service] -->
<!-- [START firebase_iid_service] -->
<service android:name=".services.MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<!-- [END firebase_iid_service] -->
When I included all the library source code as a module in my App, everything worked well, but when I included only the AAR generated, I received this error when I run my application:
java.lang.RuntimeException: Unable to instantiate service com.example.lib.services.MyFirebaseMessagingService: java.lang.ClassNotFoundException: com.example.lib.services.MyFirebaseMessagingService

The service com.example.lib.services.MyFirebaseInstanceIDService works correctly.
What I need to do with AAR generated library to work?

For FCM follow this step :
1 - in main Build.gradle (not in app folder) add this line :
buildscript {
// ...
dependencies {
// ...
classpath 'com.google.gms:google-services:3.0.0'
}
2- in app/build.gradle add this line :
apply plugin: 'com.android.application'
android {
// ...
}
dependencies {
// ...
compile 'com.google.firebase:firebase-core:9.8.0'
compile 'com.google.firebase:firebase-messaging:9.8.0'
// Getting a "Could not find" error? Make sure you have
// the latest Google Repository in the Android SDK manager
}
// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'
Note : "Android Support Repository" in you SDk most be updated .
Hope this help

click on Build - > Clean then install & run the app

Google Play Service FATAL ERROR

In my project I use GCM for push notification from server.
I foollow instruction https://developers.google.com/android/guides/setup to add Google Play Service in my project.
And everything work fine on my device (Galaxy NOTE S3), but when I start testing on another emulators (include genymotion) I got FATAL ERROR:
FATAL EXCEPTION: main

I check availability by method:
public static boolean checkPlayServices(Activity activity) {
GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
int resultCode = apiAvailability.isGooglePlayServicesAvailable(activity);
if (resultCode != ConnectionResult.SUCCESS) {
if (apiAvailability.isUserResolvableError(resultCode)) {
apiAvailability.getErrorDialog(activity, resultCode, PLAY_SERVICES_RESOLUTION_REQUEST)
.show();
}
return false;
}
return true;
}
And call this method in onResume of MainActitvity.class:
#Override
protected void onResume() {
super.onResume();
if(SMSSenderHelper.checkPlayServices(this)){
startService(new Intent(this, RegistrationIntentService.class));
}else{
finish();
}
}
SOLUTION (in my case):
review your build.gradle
change Application class:
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}

This is some line of code you have to define in Manifest file if you want to use GCMListenerService:
<receiver
android:name="com.google.android.gms.gcm.GcmReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="training.com.chatgcmapplication" />
</intent-filter>
</receiver>
<service
android:name="training.com.services.MessageListenerService"
android:exported="false" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</service>

Did you see any Google related apps (Ex: Google Play Store, Gmail...) in your emulator? If not, your emulator does not include Google service, so the Exception will be occured. Try to install Gapps for your genymotion and try again.
Edit:
Have you added Google Play Services library like Google guidline?
Note from Google guidline (emulator 4.2.2 and above):
To test your app when using the Google Play services SDK, you must use
either:
A compatible Android device that runs Android 2.3 or higher and
includes Google Play Store.
The Android emulator with an AVD that runs
the Google APIs platform based on Android 4.2.2 or higher.

NotificationListenerService with RemoteController.OnClientUpdateListener crashes on API18 (4.3)

The Problem
I want to implement the new RemoteController API, which has been introduced with API19 (Kitkat,4.4). The API requires me to implement a class which extends from NotificationListenerService (introduced with API18) and implements the RemoteController.OnClientUpdateListener interface. (Further information on how to implement all this can be found here and a very helpful example project can be found here)
Everything's working as it should on my API19 (Kitkat,4.4) device and every other API<18 device. However the problem is, that the app crashes right away on API18 (Jelly bean, 4.3), because the "android.service.notification.NotificationListenerService" is being sent and starts my RemoteService, which then crashes the app instantly with the following Stacktrace:
05-24 09:32:48.945 893-893/com.example E/AndroidRuntime﹕ FATAL EXCEPTION: main

...
This is caused by the simple fact, that RemoteController and therefore the implemented interface RemoteController.OnClientUpdateListener is not available on API18, but NotificationListenerService is. The intent is not being sent on every device
What I've tried so far
Put another layer of abstraction on it and build a simple "if (API>=19)" check.
I tried to do this by using a second empty NotificationListenerService which would just work as a kind of callthrough Service. I would put that second Service in my AndroidManifest, so that it receives the intent instead, and then I'd just put the "if (API>=19)" check in its onCreate and start my actual RemoteService from there. The result is, that my App doesn't crash any more (yay). Unfortunately it also doesn't work in API19 Kitkat any more :(. I think that's because I have to register my RemoteService as a listener in my AndroidManifest directly, or otherwise it won't receive anything.
Code snippets
RemoteService.java:
public class RemoteService extends NotificationListenerService
implements RemoteController.OnClientUpdateListener {
...
}
AndroidManifest.xml:
<manifest ...>
<application ...>
<service android:name="com.example.RemoteService"
android:label="#string/app_name"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
</service>
</application>
</manifest>

The solution
Put a bool in an xml file in values and values-v19. Set it to false in values and to true in values-v19. Now set the NotificationListenerService's "android:enabled" tag to this bool.
./values/bool_switches.xml:
<resources>
<bool name="remotecontrollerservice_enabled">false</bool>
</resources>
./values-v19/bool_switches.xml:
<resources>
<bool name="remotecontrollerservice_enabled">true</bool>
</resources>
./AndroidManifest.xml:
...
<service android:name=".services.RemoteControllerService"
android:label="#string/scrobblingservice_string"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"
android:enabled="#bool/remotecontrollerservice_enabled">
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService"/>
</intent-filter>
</service>
...

Just disable the service with android:enabled="false", then in Application.onCreate enable it if the device is running KitKat or newer.

Explanation for random ClassNotFoundExceptions?

I have an app with ~11k active installs for which I sometimes receive ClassNotFoundExceptions that I can't explain. They look like this:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{name.of.my.MainActivityClass}: java.lang.ClassNotFoundException: name.of.my.MainActivityClass in loader dalvik.system.PathClassLoader[/mnt/asec/name.of.my-2/pkg.apk]

... 11 more
I received some of these exceptions from users that updated my app (not only for the most recent version), so I think it is not a problem that is specific to some phones as the app worked for them before.
I got these exception reports for my main activity class, a receiver class and a BackupAgent class.
All of those classes are always instantiated directly from Android. My Manifest file looks like this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="name.of.my"
android:versionCode="20"
android:versionName="1.10.2"
android:installLocation="auto">
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="8" />
<application android:icon="#drawable/icon" android:label="#string/app_name" android:backupAgent="name.of.my.OwnBackupAgent">
<activity android:name="name.of.my.MainActivityClass"
android:label="#string/app_name"
android:theme="#style/MyTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="name.of.my.OwnReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.media.RINGER_MODE_CHANGED" />
</intent-filter>
</receiver>
</application>
</manifest>
After searching the net for some hours, the most likely explanations I found are:
it might be related to moving the app to SD card while there are still some services running (but the android dev guide says that all services are canceled in this case, and it doesn't explain why my main activity class suddenly can't be found anymore)
the .apk might be corrupted after updating via the android market. Could this be true? If yes, what can I do against it - if not, what else might be the problem?
