BroadcastReceiver可以启动我自己的应用程序吗?

标签: android broadcastreceiver

我希望当手机收到来自AC2M的推送通知时,必须在通知栏中显示通知,如果用户按下通知,我的应用必须启动并显示描述该通知的特定活动,并且不是我的应用程序的正常拳头活动。

有可能实现这一目标吗?谁能解释我怎么样?

我的应用必须开始收听接收器吗?或者我的应用程序可以不启动?

感谢

从C2DM,是的,这是可能的。

在C2DMReceiver.java类中使用以下代码:

@Override
protected void onMessage(Context context, Intent intent) {

    Bundle extras = intent.getExtras();
    if (extras != null) {
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        int icon = R.drawable.icon;        // icon from resources
        CharSequence tickerText = "MyApp Notification";              // ticker-text
        long when = System.currentTimeMillis();         // notification time
        Context context21 = getApplicationContext();      // application Context
        CharSequence contentTitle = "MyApp Notification Title";  // expanded message title
        CharSequence contentText = (CharSequence) extras.get("message");     // expanded message text
    Intent notificationIntent = new Intent(this, YourActivityName.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

        Notification notification = new Notification(icon, tickerText, when);
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notification.defaults |= Notification.DEFAULT_LIGHTS;
        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notification.setLatestEventInfo(context21, contentTitle, contentText, contentIntent);
        mNotificationManager.notify(Constants.NOTIFICATION_ID, notification);

    }
}

要让您的应用程序开始收听,请确保您已在项目的AndroidManifest.xml文件中声明了以下内容(以及其他必要的必需权限):

<service android:name=".C2DMReceiver" />

 <!-- Only C2DM servers can send messages for the app. If permission is not set - any other app can generate it 


       <receiver android:name=".C2DMReceiver" android:permission="com.google.android.c2dm.permission.SEND"> -->
             <receiver android:name="com.google.android.c2dm.C2DMBroadcastReceiver"
                android:permission="com.google.android.c2dm.permission.SEND">
              <!-- Receive the actual message -->
              <intent-filter>
                  <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                  <category android:name="com.your.packagename" />
              </intent-filter>
              <!-- Receive the registration id -->
              <intent-filter>
                  <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
                  <category android:name="com.your.packagename" />
              </intent-filter>
          </receiver>
