android 使用 parse.com api 通过推送通知实现聊天

Question

我正在做一个聊天应用程序。在应用程序中，我必须在使用 parse andorid sdk 的推送通知的帮助下进行聊天。我成功地在不同用户之间生成推送通知。但无法接收推送并将其数据添加到列表视图中。这是maifest文件的代码

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />





<application
    android:name="example.chat.ChatApplication"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >


     <activity
        android:name="com.facebook.LoginActivity"
        android:label="@string/app_name" />

    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/app_id" />

    <activity
        android:name="example.chat.LoginActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="example.chat.FriendslIst"
        android:label="Friend list"
        android:screenOrientation="portrait" >
    </activity>
    <activity
        android:name="example.chat.RegisterActivity"
        android:label="@string/title_activity_register"
        android:screenOrientation="portrait" >
    </activity>
    <activity
        android:name="example.chat.FriendListActivity"
        android:label="@string/title_activity_friend_list"
        android:screenOrientation="portrait" >
    </activity>
    <activity
        android:name="example.chat.ChatActivity"
        android:label="@string/title_activity_chat"
        android:screenOrientation="portrait" >
    </activity>

    <service android:name="com.parse.PushService" />

    <receiver android:name="com.parse.ParseBroadcastReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <action android:name="android.intent.action.RECEIVE_BOOT_COMPLETED" />
            <action android:name="android.intent.action.USER_PRESENT" />
        </intent-filter>
    </receiver>



     <receiver android:name="example.chat.MyCustomReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <action android:name="android.intent.action.USER_PRESENT" />
            <action android:name="example.chat.UPDATE_STATUS" />
        </intent-filter>
    </receiver>

</application>

和我的自定义接收器的代码

public class MyCustomReceiver extends BroadcastReceiver {
    private static final String TAG = "MyCustomReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {


        Toast.makeText(context, ""+intent, Toast.LENGTH_LONG).show();
        }
}

我从 java 代码中发送这样的推送：

ParseQuery<ParseInstallation> query = ParseInstallation.getQuery();
        query.whereEqualTo("device_id", target);
        ParsePush push = new ParsePush();
        push.setQuery(query);
        push.setMessage(message);
        push.setExpirationTimeInterval(86400);
        push.sendInBackground();

请告诉我使用接收器接收数据的错误在哪里，以及当我接收推送时该怎么做意味着任何逻辑或想法可以进一步推进。提前致谢

这是清单文件.....

  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="your package name"
        android:versionCode="1"
        android:versionName="1.0" >

        <uses-sdk
            android:minSdkVersion="15"
            android:targetSdkVersion="16" />

        <uses-permission android:name="android.permission.INTERNET" />
        <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
        <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
        <uses-permission android:name="android.permission.VIBRATE" />

        <application
            android:allowBackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <activity
                android:name="your package name.YourActivity"
                android:label="@string/app_name" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />

                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>

            <service android:name="com.parse.PushService" />

            <receiver android:name="com.parse.ParseBroadcastReceiver" >
                <intent-filter>
                    <action android:name="android.intent.action.BOOT_COMPLETED" />
                    <action android:name="android.intent.action.RECEIVE_BOOT_COMPLETED" />
                    <action android:name="android.intent.action.USER_PRESENT" />
                </intent-filter>
            </receiver>
            <receiver android:name="your package name.YourCustomReceiver" >
                <intent-filter>
                    <action android:name="android.intent.action.BOOT_COMPLETED" />
                    <action android:name="android.intent.action.USER_PRESENT" />
                    <action android:name="your package name.UPDATE_STATUS" />
                </intent-filter>
            </receiver>
        </application>

    </manifest>

使用此代码接收推送...

public class MyCustomReceiver extends BroadcastReceiver {

字符串标题，发件人，味精；

    @Override
    public void onReceive(Context context, Intent intent) {

        Bundle extras = intent.getExtras();

        String message = extras != null ? extras.getString("com.parse.Data")
                : "";

        Log.e("message ", " " + message);

        JSONObject jObject;
        try {
            if (message != null && !message.equals("")) {
                jObject = new JSONObject(message);

                from = jObject.getString("from");
                msg = jObject.getString("title");
                title = jObject.getString("msg");



                GCMMessage gcmMessage = new GCMMessage();
                gcmMessage.setMsg_body(msg);
                gcmMessage.setMsg_title(title);
                gcmMessage.setType(0);
                gcmMessage.setDateTime(time);



                DatabaseUtil.insertMessage(context, gcmMessage);
            }

        }

        catch (JSONException e) {
            e.printStackTrace();
        }

    }

}

这里是发送推送的代码...

    JSONObject obj;
            try {
                obj =new JSONObject();
                obj.put("alert","oman expert ");
                obj.put("action","Your Package name.UPDATE_STATUS");



data.put("from", ParseUser.getCurrentUser().getUsername());         


    obj.put("msg","hi");
    obj.put("title","msg");
                ParsePush push = new ParsePush();
                ParseQuery query = ParseInstallation.getQuery();



                push.setQuery(query);
                push.setData(obj);
                push.sendInBackground(); 
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

如有任何进一步的疑问，请告诉我......

在上面的代码示例中，你漏掉了一些东西，

检查您的 AndroidManifest.xml 文件，并添加 c2dm 权限，

权限 android:name="你的 package.permission.C2D_MESSAGE" android:protectionLevel="signature"

使用权限 android:name="com.google.android.c2dm.permission.RECEIVE"

uses-permission android:name="your package.permission.C2D_MESSAGE"

发送数据时，在数据中设置动作，

 JSONObject data = new JSONObject();
    try {
        data.put("action", "your package.GOT_MESSAGE");
        data.put("ya", ya);
        data.put("from", ParseUser.getCurrentUser().getUsername());
    }catch (Exception e){
        e.printStackTrace();
        return;
    }


    ParsePush parsePush = new ParsePush();
    parsePush.setData(data);
