【问题描述】：

这是应用程序代码：

import android.app.Application;
import android.util.Log;

import com.ghostriley.sgt.ghostchat.UI.MainActivity;
import com.parse.Parse;
import com.parse.ParseException;
import com.parse.ParseInstallation;
import com.parse.ParseObject;
import com.parse.ParseAnalytics;
import com.parse.ParsePush;
import com.parse.ParsePushBroadcastReceiver;
import com.parse.PushService;
import com.parse.SaveCallback;



public class GhostChatApplication extends Application {
    @Override
    public void onCreate(){
        super.onCreate();

        Parse.initialize(this, "P0zIagKQvEGdopuoLZuucgzC7H4oz64U7GZkGe1n", "mT15MV8OFEMTDNQaGU5XdLHTXMsNxnUxJdXVp4O3");    
        ParseInstallation.getCurrentInstallation().saveInBackground();

    }

}

虽然Docs中没有提到订阅频道，但是我测试的时候确实订阅成功了。如果我在其中放入一些随机字符串将不起作用，因此“testNotification”可能是正确的。这是清单：

        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value="com.ghostriley.sgt.ghostchat.UI.MainActivity" />
        </activity>

    </application>

</manifest>

我删除了应用程序标签以使代码变小。

【问题讨论】：

标签： android parse-platform push-notification

【解决方案1】：

<service> 和 <receiver> 标记都必须在 <application></application> 内部，与 <activity> 完全相同，而不是在外部，因此将它们插入内部

<application
    android:name=".GhostChatApplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.ghostriley.sgt.ghostchat.UI.MainActivity" />
    </activity>

    <service android:name="com.parse.PushService" />
    <receiver android:name="com.parse.ParsePushBroadcastReceiver"
        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>
    <receiver android:name="com.parse.GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <category android:name="com.ghostriley.sgt.ghostchat" />
        </intent-filter>
    </receiver>

</application>

并将它们从外面的任何其他地方移除
