Question

我可以从GCM服务器获取注册ID并捕获与gcm-alert Push Notification online tool一起发送的通知，但 GcmIntentService 的 onHandleIntent 方法永远不会被调用。<登记/> 有一件有趣的事情是调用 onDestroy 方法。任何帮助将不胜感激。

的 GcmIntentService.java

package ondermerol.com.studiopushtest;

import android.app.IntentService;
import android.content.Intent;
import android.content.Context;
import android.util.*;
/**
 * An {@link IntentService} subclass for handling asynchronous task requests in
 * a service on a separate handler thread.
 * <p/>
 * TODO: Customize class - update intent actions, extra parameters and static
 * helper methods.
 */
public class GcmIntentService extends IntentService {

    private final static String Tag="---IntentServicetest";

    public GcmIntentService() {
        // TODO Auto-generated constructor stub
        super("GcmIntentService");
        Log.d(Tag, "Constructor");
    }
    @Override
    public void onDestroy() {
        Log.d(Tag, "onDestroy()");
        super.onDestroy();
    }
    @Override
    public void onStart(Intent intent, int startId) {
        Log.d(Tag, "onStart()");
        super.onStart(intent, startId);
    }

    @Override
    public void setIntentRedelivery(boolean enabled) {
        Log.d(Tag, "setIntentRedelivery()");
        super.setIntentRedelivery(enabled);
    }
    @Override
    protected void onHandleIntent(Intent intent) {
        // TODO Auto-generated method stub
        Log.d(Tag, "IntentServicetest is onHandleIntent!");

    }

的 GcmBroadcastReceiver.java

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

    public GcmBroadcastReceiver() {
    }

    // Receives the broadcast directly from GCM service
    @Override
    public void onReceive(Context context, Intent intent) {

        // TODO Auto-generated method stub
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                ondermerol.com.studiopushtest.GcmIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }
}

的的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="ondermerol.com.studiopushtest" >

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <receiver
            android:name=".GcmBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" >
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RETRY" />
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />

                <category android:name="ondermerol.com.studiopushtest" />
            </intent-filter>
        </receiver>

        <service android:enabled="true"
            android:name="ondermerol.com.studiopushtest.GcmIntentService">
        </service>

    </application>

</manifest>

Answer 1

来自IntentService#onStartCommand(Intent intent, int flags, int startId)的文档：

/**
 * You should not override this method for your IntentService. Instead,
 * override {@link #onHandleIntent}, which the system calls when the IntentService
 * receives a start request.
 * @see android.app.Service#onStartCommand
 */

我看到您在实施中覆盖onStartCommand()，尝试坚持使用默认值。

Answer 2

我看到它被调用但该方法中的断点永远不会起作用，因为 IntentService 在另一个线程中工作。
并且调用了 onDestroy ，因为从onHandleIntent（）返回后，IntentService会自行停止。
感谢您的回答Service.onDestroy() is called directly after creation, anyway the Service does its work

永远不会调用Android onHandleIntent
