I have a requirement (android) where my app should run its main activity automatically when a push notification is received without the user clicking on notification in system tray. I am having a map where it shows current location, but in the push, i will receive a location, and i need my map in the main activity to move the camera to the currently received location on receiving the push, and alert the user with a custom sound. All this should happen without the user clicking on anything. Pls help. Thanks in advance.

推荐答案

是的，这是可能的.Parse.com 文档说:

Yes, it's possible. Parse.com documentation says:

您还可以指定在推送通知时在后台触发的 Intent已收到.这将允许您的应用程序对通知执行自定义处理，并且无论您是否选择显示系统托盘消息，都可以使用.实施自定义通知处理，在您的推送通知数据中设置 Action 条目字典到您要触发的 Intent 操作.Android 指南建议你用你的包名作为动作的前缀，以避免与其他的命名空间冲突运行应用.

You can also specify an Intent to be fired in the background when the push notification is received. This will allow your app to perform custom handling for the notification, and can be used whether or not you have chosen to display a system tray message. To implement custom notification handling, set the Action entry in your push notification data dictionary to the Intent action which you want to fire. Android guidelines suggest that you prefix the action with your package name to avoid namespace collisions with other running apps.

所以你以这种方式发送推送通知:

So you send push notifications in this way:

JSONObject data = new JSONObject("{"action": "com.example.UPDATE_STATUS""}));

ParsePush push = new ParsePush();
push.setData(data);
push.sendPushInBackground();

然后在您的 AndroidManifest.xml 中注册一个广播接收器，每当收到带有 com.example.UPDATE_STATUS 的 action 参数的推送通知时都会调用该接收器:

Then in your AndroidManifest.xml register a broadcast receiver that will be called whenever a push notification is received with an action parameter of com.example.UPDATE_STATUS:

<receiver android:name="com.example.MyBroadcastReceiver" android:exported="false">
  <intent-filter>
    <action android:name="com.example.UPDATE_STATUS" />
  </intent-filter>
</receiver>

在您的广播接收器中，您可以开始一项新活动:

In your broadcast receiver you can start a new activity:

public class MyBroadcastReceiver extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {
    context.startActivity(new Intent(context, MyActivity.class));
  }
}
