向 ComponentInfo 发送广播时出现异常

Question

我有一个 Google 云消息的接收器，它已在 AndroidManifest.xml:

中注册

    <receiver
        android:name="com.app.android.push.HSPushReceiver"
        android:permission="com.google.android.c2dm.permission.SEND"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <action android:name="com.google.android.c2dm.intent.REGISTER" />
            <category android:name="com.app.android" />
        </intent-filter>
    </receiver>

我可以在应用程序处于前台或被杀死时收到消息。但是，如果我启动带有通知的 IntentService，然后将主 activity 滑开，那么如果我发送通知，我会遇到以下崩溃：

08-29 15:29:37.785 W/ActivityManager(  757): Scheduling restart of crashed service com.app.android/.HSNotificationService in 578824ms

HSNotificationService 不知何故崩溃了。当 activity 被刷走时，PushReceiver 不知何故死了。如何解决这个问题？

Answer 1

在 here. Seems to be an Android bug reported here and here 中发现了同样的问题。

我使用了 here and it's working for me. Someone said it has side effect though. side effect

中的解决方法

解决方法是在前台服务中启动虚拟 activity

@Override
public void onTaskRemoved( Intent rootIntent ) {
    Intent intent = new Intent( this, ServiceKeepActivity.class );
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);
}
