Android GCM a veces se bloquea la aplicación porque com.google.android.gms.gcm.GcmListenerService se rechaza desde java.util.concurrent.ThreadPoolExecutor

Question

desde que actualicé GCM a 8.4.0, a veces mi aplicación falla y el registro muestra la siguiente excepción:

Fatal Exception: java.lang.RuntimeException: Unable to start service com.myapp.app.Service_GCMListenerService@ea3f6c7 with Intent { act=com.google.android.c2dm.intent.RECEIVE flg=0x10000010 pkg=com.myapp.app cmp=com.myapp.app/.Service_GCMListenerService (has extras) }: java.util.concurrent.RejectedExecutionException: Task com.google.android.gms.gcm.GcmListenerService$1@7b28d65 rejected from java.util.concurrent.ThreadPoolExecutor@f392a3a[Running, pool size = 9, active threads = 9, queued tasks = 128, completed tasks = 0]

Este bloqueo no explica dónde está el error en mi código. ¿Que debería hacer?

Esta es mi implementación de GCM:

Manifiesto de Android :

Service_GCMListenerService

public class Service_GCMListenerService extends GcmListenerService {
@Override
public void onDeletedMessages() {
super.onDeletedMessages();
PushManager.checkForNewPush();
}
@Override
public void onMessageReceived(String from, Bundle data) {
super.onMessageReceived(from, data);
PushManager.processPush(this,false,data.getString("message"));
}
}

Service_IDListenerService

public class Service_IDListenerService extends InstanceIDListenerService {
/**
* Called if InstanceID token is updated. This may occur if the security of
* the previous token had been compromised. This call is initiated by the
* InstanceID provider.
*/
@Override
public void onTokenRefresh() {
GCMUtils.registerNewInstanceID();
}

THREAD_POOL_EXECUTOR de THREAD_POOL_EXECUTOR tiene un límite codificado de 128 tareas en cola. Tu problema es que estás ejecutando muchas tareas con ese ejecutor.

Si no está llamando directamente a executeOnExecutor en cualquiera de sus AsyncTasks, el culpable más probable son los métodos de terceros que devuelven un ListenableFuture , especialmente aquellos que realizan operaciones de red. Probablemente querrá una forma de ejecutarlos en serie. Mover todas esas operaciones a AsyncTasks ejecutándose en AsyncTask.SERIAL_EXECUTOR sería una solución.
