android - 如何在Android中获取推送通知消息？

我正在尝试接收推送通知消息并发送通知消息，但得到的空值没有接收到任何消息。
低于代码

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    String messageType = gcm.getMessageType(intent);
    Log.d("push","msg type: " + messageType);
    if (!extras.isEmpty()) {
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
                .equals(messageType)) {
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
                .equals(messageType)) {
        } else if (!extras.isEmpty() && GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
                .equals(messageType)) {
            Log.d("push notify msg: ", extras.toString());
            sendNotification(extras.toString());
        }
    }
    GcmBroadcastReceiver.completeWakefulIntent(intent);
}

最佳答案

创建一个接收者并在清单中声明它。

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    ComponentName comp = new ComponentName(context.getPackageName(),XYZIntentService.class.getName());
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
 }
}

显示：

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

            <category android:name="PKG_NAME" />
        </intent-filter>
    </receiver>

元数据标记：

<meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

权限：

<permission
    android:name="com.vuliv.player.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />

<uses-permission android:name="com.vuliv.player.permission.C2D_MESSAGE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/>

现在您可以将代码添加到xyzintentservice以获取gcm通知。
