java - 在打开推送通知时解析推送 "No Activity Found"

Question

我使用 Parse 制作了一个应用程序作为后端。我能够收到通知，但当我点击它时，应用程序崩溃了。

这是 java 和 XML 文件。

我想在点击通知时打开 HomeActivity。任何帮助将不胜感激。如果需要任何其他文件，请告诉我，我会添加它。

引自 Ahmad Raza 的以下帖子 Exception when opening Parse push notification

您可以扩展 ParsePushBroadcastReceiver 并覆盖 onPushOpen 方法。

public class Receiver extends ParsePushBroadcastReceiver {

    @Override
    public void onPushOpen(Context context, Intent intent) {
        Log.e("Push", "Clicked");
        Intent i = new Intent(context, HomeActivity.class);
        i.putExtras(intent.getExtras());
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
}

在 list 中使用它，(而不是使用 ParsePushBroadcastReceiver)

<receiver
        android:name="your.package.name.Receiver"
        android:exported="false" >
    <intent-filter>
        <action android:name="com.parse.push.intent.RECEIVE" />
        <action android:name="com.parse.push.intent.DELETE" />
        <action android:name="com.parse.push.intent.OPEN" />
    </intent-filter>
</receiver>
