Question

我的Android应用程序从不在2.3设备上接收GCM消息，但它在4.x设备上接收。我可以成功注册所有设备（2.3和4.x）。我认为这可能与this issue有关，但似乎我的android清单配置正确。有人能够注意我的IntentService和BroadcastReceiver，看看他们是否注意到任何问题？任何帮助将不胜感激。请注意，在我附加调试器的情况下发送通知时，永远不会为Android 2.3调用onHandeIntent（）。我检查了4.x设备，它们确实触发了onHandleIntent（）中的调试器。谢谢！

广播接收器：

package my.package;

import android.app.*;
import android.content.*;

public class GcmBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        NotificationIntentService.runIntentInService(context, intent);
        setResultCode(Activity.RESULT_OK);
    }
}

通知意向服务

public class NotificationIntentService extends IntentService {
    private String TAG = "NotificationIntentService";
    public NotificationIntentService() {
        super(AppConstants.GCM_SENDER_ID);
    }

    public NotificationIntentService(String name) {
        super(name);
        // TODO Auto-generated constructor stub
    }

    private static PowerManager.WakeLock sWakeLock;
    private static final Object LOCK = NotificationIntentService.class;

    static void runIntentInService(Context context, Intent intent) {
        synchronized(LOCK) {
            if (sWakeLock == null) {
                PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
                sWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "my_wakelock");
            }
        }
        sWakeLock.acquire();
        intent.setClassName(context, NotificationIntentService.class.getName());
        context.startService(intent);

    public final void onHandleIntent(Intent intent) {
        try {
            String action = intent.getAction();
            if (action.equals("com.google.android.c2dm.intent.REGISTRATION")) {
                //don't care.
            } else if (action.equals("com.google.android.c2dm.intent.RECEIVE")) {
                handleMessage(intent);
            }
        } finally {
            synchronized(LOCK) {
                sWakeLock.release();
            }
        }
    }

    private void handleMessage(Intent intent) {
        Bundle b = intent.getExtras();
        String text = b.getString("text"),
               title = b.getString("title"),
               largeImageUrl = b.getString("largeImageUrl");

        if (bit != null) nc.setLargeIcon(bit);
        nm.notify(0, nc.build());
    }
}

Answer 1

我能看到的第一个潜在问题是：

permission元素中的包名称与uses-permission元素中的包名称不同。在我的应用程序（针对Android 2.2）中，它们完全相同。

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="my.package.matchtracker.permission.C2D_MESSAGE" />
<permission android:name="my.package.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />

Answer 2

如果您正在使用具有不同applicationId的产品风味，请参阅我的answer问题在Android 2.3.6 v上未收到GCM消息但在android 4.X v上正常工作

Answer 3

GCM需要在设备上安装Google Play服务，但在版本2.3中，默认情况下不会安装。

Android 4.x设备接收GCM消息，但Android 2.3设备不接收
