由于com.google.android.gms.gcm.GcmListenerService被java.util.concurrent.ThreadPoolExecutor拒绝，因此Android GCM有时应用程序崩溃 [英] Android GCM sometimes app crashes because com.google.android.gms.gcm.GcmListenerService is rejected from java.util.concurrent.ThreadPoolExecutor

问题描述

自从我将GCM升级到8.4.0以来，我的应用有时会崩溃，并且日志显示以下异常:

since I upgraded GCM to 8.4.0 my app sometimes crashes and the log shows the following exception:

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]

此崩溃不解释我的代码中的错误在哪里.我该怎么办?

This crash does not explain where is the error in my code. What should I do?

这是我对GCM的实现:

This is my implementation of GCM:

Android清单:

<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="com.myapp.app" />
        </intent-filter>
    </receiver>

    <service
        android:name=".Service_GCMListenerService"
        android:exported="false" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        </intent-filter>
    </service>
    <service
        android:name=".Service_IDListenerService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.android.gms.iid.InstanceID"/>
        </intent-filter>
    </service>

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();
}

推荐答案

AsyncTask的THREAD_POOL_EXECUTOR的硬编码限制为排队的128个任务.您的问题是您正在该执行程序上执行许多任务.

AsyncTask's THREAD_POOL_EXECUTOR has a hard-coded limit of 128 tasks queued. Your problem is that you are executing a lot of tasks on that executor.

如果您没有在任何AsyncTask上直接调用executeOnExecutor，则最可能的罪魁祸首是返回ListenableFuture的第三方方法，尤其是执行网络操作的第三方方法.您可能需要一种串行执行这些方法的方法.将所有这些操作移到在AsyncTask.SERIAL_EXECUTOR上执行的AsyncTasks中将是一种解决方案.

If you are not directly calling executeOnExecutor on any of your AsyncTasks, the most likely culprit are third-party methods that return a ListenableFuture, especially those performing network operations. You'll probably want a way to execute those serially. Moving all of those operations into AsyncTasks executing on AsyncTask.SERIAL_EXECUTOR would be one solution.
