当应用程序关闭时,Android 不会收到来自 Parse Push 的推送通知 [英] Android doesn't receive push notification from Parse Push when app is closed
问题描述
当我在 Android 手机上测试 Parse Push 时,只要应用程序运行,推送通知就会出现.如果应用程序已关闭:我只会收到一条消息,内容为
- 我没有收到任何推送 - 但仍然收到停止通知弹出窗口.我一步一步地遵循了 Parse 的快速入门指南.
When I am testing the Parse Push to my Android phones the push notification come through as long as the app runs.
If the app is closed: I just get a message saying <App name> has stopped.
- I don't receive any of the pushes - but still got the stop notification popup. I have followed the Quickstart guide from Parse step by step.

03-03 21:27:10.829 31149-31149/org.ostsia.ostsia E/com.parse.PushService﹕ The Parse push service cannot start because Parse.initialize has not yet been called. If you call Parse.initialize from an Activity's onCreate, that call should instead be in the Application.onCreate. Be sure your Application class is registered in your AndroidManifest.xml with the android:name property of your <application> tag.

推荐答案
在 Application 类中初始化解析,如下所示
Have the parse initialized in Application class similar as below
public class AppClass extends Application {
@Override
public void onCreate() {
super.onCreate();
// Parse.enableLocalDatastore(this); // if you need this, put before init
Parse.initialize(this, "gV6QK", "JJmFo99");
PushService.setDefaultPushCallback(getApplicationContext(), MainActivity.class);
ParseInstallation.getCurrentInstallation().saveInBackground();
}
}
不要忘记在清单中引用您的应用类
Don't forget to reference your app class in manifest
<application android:name=".AppClass">
从 MainActivity 中删除 Parse init
Remove Parse init from MainActivity
