Question

我正在关注Android开发人员的GCM演示。得到以下情况。我没有调用GCMIntentService中的OnHandleIntent。有人可以帮忙吗？

package com.xyz.ads;


import com.google.android.gms.gcm.GoogleCloudMessaging;

import android.app.IntentService;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class GcmIntentService extends IntentService {
    public GcmIntentService() {
        super("GcmIntentService");
        //super.onCreate();
        //super.onHandleIntent();
    }

    public void onCreate() {
        super.onCreate();

    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        super.onStartCommand(intent, startId, startId);
        Log.i("LocalService", "Received start id " + startId + ": " + intent);

        return START_STICKY;
    }
    public static final String TAG = "GCM Demo";

    @Override
    protected  void onHandleIntent(Intent intent) {
        Bundle extras = intent.getExtras();
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        // The getMessageType() intent parameter must be the intent you received
        // in your BroadcastReceiver.
        String messageType = gcm.getMessageType(intent);

        // Release the wake lock provided by the WakefulBroadcastReceiver.
        GcmBroadcastReceiver.completeWakefulIntent(intent);
    }
}

这是我的BroadCastReceiver

package com.xyz.ads;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.support.v4.content.WakefulBroadcastReceiver;


public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),GcmIntentService.class.getName());

        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }
}

和我的清单

        </service>

    </application>

</manifest>

onReceive内部接收器被调用和意图服务的构造函数..

Answer 1

我会说你在班级名称中缺少一个点。

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

点代表您应用的包名称。
假设您的包名为com.example.app。然后编写.GcmIntentService与编写com.example.app.GcmIntentService具有相同的效果。

Answer 2

试试这个

<receiver
            android:name="com.xyz.ads.GcmBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" >
            <intent-filter>

                <!-- Receives the actual messages. -->
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />

                <category android:name="com.xyz.ads" />
            </intent-filter>
        </receiver>

 <service
            android:name="com.xyz.ads.GcmIntentService"
            android:enabled="true" >
        </service>

Answer 3

我遇到了同样的问题，但它不是代码（就像你的代码一样，就像文档说的那样：http://developer.android.com/google/gcm/client.html），它是Eclipse项目。

检查这是否可以帮助您：

执行重构并将服务从一个包移动到另一个包。检查androidManifest.xml是否自动更改包。如果没有，那么你遇到的问题与我相同。

我通过删除ServiceIntent类并创建一个新的（具有相同内容）来解决它。似乎我的服务已经断开连接或类似的事情，并且当时我意识到通过比较代码我已经疯了。

使用新的，如果再次检查，您将看到androidmanifest.xml中的包更改以及GcmBroadcastReceiver调用的服务!! ：）

GcmIntentService中的onHandleIntent未被调用
