解析SDK实现定制的BroadcastReceiver在Android的推送通知 [英] Parse SDK implement custom BroadcastReceiver for push notifications in android
问题描述
我想开始使用Android上的解析推送通知,但我无法找到任何方式来实现自己的BroadcastReceiver这将响应推送通知执行操作。
在他们的入门,他们给那里的接收器和意图的服务包含在JAR文件中的程序示例(和code不落实,这样我就可以尝试用它玩)。类似的问题已经在这里问,但它的两岁得到的答复有11 downvotes。
有一些其他的博客文章,例如如这里,但他们没有正常工作(一个在链接两岁)。
所以,请好心提示一步步的方式来实现相同的。
编辑:
我试过code。通过droidx的建议。但是,这是行不通的。我送我的AndroidManifest.xml(在code其余是完全一样的,他建议):

下面是一个例子!

}
指导,接收器代替机器人的名字您的自定义路径的BroadcastReceiver
<接收

<作用机器人:名字=com.parse.push.intent.RECEIVE/>
<作用机器人:名字=com.parse.push.intent.DELETE/>
<作用机器人:名字=com.parse.push.intent.OPEN/>
&所述; /意图滤光器>
< /接收器>
在您的应用程序类,确保已订阅推送解析像这样
Parse.initialize(这一点,ParseUtils.PARSE_APPLICATION_ID_DEV,ParseUtils.PARSE_CLIENT_KEY_DEV);
ParseObject.registerSubclass(Article.class); ParsePush.subscribeInBackground(,新SaveCallback(){
@覆盖
公共无效完成(ParseException的E){
如果(E == NULL){
Log.d(TAG,成功订阅广播频道。);
}其他{
Log.e(TAG,未能认购推,E);
}
}
});
更新:
以上广播接收预计从parse仪表盘发送一个JSON对象通常通知包含三个名称值对的:
{警告:提示信息,称号:标题,URI:喇嘛喇嘛}
当你只使用普通字符串例如:世界,你好!在解析推的仪表板,内部它去,因为只有警示标签。像这样: {警告:世界你好!,标题为=空/,URI=空/}
广播接收器code上面没有这个null检查,所以它与例外抓不抓的标题/ URI。
所以,你可以根据你是从推送通知期待什么添加一些null检查。
事情是这样的:
JSONObject的JSON =新的JSONObject(intent.getExtras()的getString(com.parse.Data)。);
Log.d(TAG,json.getString(警报)的toString()); 如果(json.has(标题)){
。notificationTitle = json.getString(题)的toString();
}
如果(json.has(警告)){
。notificationAlert = json.getString(提醒)的toString();
} 如果(json.has(URI)){
notificationURI = json.getString(URI);
}
然后设置相应的 contentTitle
和 contentText
在通知
NotificationCompat.Builder建设者=
新NotificationCompat.Builder(上下文)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(notificationAlert)
.setContentText(notificationAlert);
希望这有助于!
I am trying to get started with Parse push notification on Android, but I could not find any way to implement my own BroadcastReceiver which would perform action in response to a push notification.
In their "getting started", they give a program sample where the receiver and the intent service is contained in the jar file (and not implemented in the code, so that I could try and play with it). A similar question has been asked here, but it's two years old and the answer has 11 downvotes.
There are a few other blog posts, e.g. as in here, but none of them work properly (the one in that link was two years old).
So please kindly suggest a step by step way to implement the same.
EDIT:
I tried the code as suggested by droidx. But it does not work. I am sending my AndroidManifest.xml (rest of the code is exactly as he suggested):
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.rahulserver.parsenotificationdemo" >
<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<!--
IMPORTANT: Change "com.parse.starter.permission.C2D_MESSAGE" in the lines below
to match your app's package name + ".permission.C2D_MESSAGE".
-->
<permission android:protectionLevel="signature"

-->
<category android:name="com.rahulserver.parsenotificationdemo" />
</intent-filter>
</receiver>
</application>
</manifest>
Here's an example!
public class ParseCustomBroadcastReceiver extends ParsePushBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
try {
JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
Log.d(TAG, json.getString("alert").toString());
final String notificationTitle = json.getString("title").toString();
final String notificationContent = json.getString("alert").toString();
final String uri = json.getString("uri");
Intent resultIntent = null;
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
resultIntent = new Intent(context, HomeScreen.class);
stackBuilder.addParentStack(HomeScreen.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
//Customize your notification - sample code
NotificationCompat.Builder builder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.mipmap.ic_notification_icon)
.setContentTitle(notificationTitle)
.setContentText(notificationContent);
int mNotificationId = 001;
NotificationManager mNotifyMgr =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotifyMgr.notify(mNotificationId, builder.build());
} catch (JSONException e) {
Log.d(TAG, e.getMessage());
}
}
}
Following this guide, replace android name for the receiver to the path of your custom broadcastreceiver
<receiver
android:name=".receivers.ParseCustomBroadcastReceiver"
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>
In your application class, make sure to have subscribed to Parse Push like this
Parse.initialize(this, ParseUtils.PARSE_APPLICATION_ID_DEV, ParseUtils.PARSE_CLIENT_KEY_DEV);
ParseObject.registerSubclass(Article.class);
ParsePush.subscribeInBackground("", new SaveCallback() {
@Override
public void done(ParseException e) {
if (e == null) {
Log.d(TAG, "successfully subscribed to the broadcast channel.");
} else {
Log.e(TAG, "failed to subscribe for push", e);
}
}
});
Update:
The above broadcast receiver expects to send a json object notification from parse dashboard usually consists of three name value pairs:
{ "alert": "Alert message", "title": "Title", "uri": "bla bla" }
When you use only plain string for eg: hello world! in parse push dashboard, internally it goes as only alert tag. something like this : {"alert" : "hello world!, "title" = null/"", "uri" = null/""}
The broadcast receiver code above doesn't have this null checks, so it's caught in the catch with exception No title/uri.
So you can add some null checks based on what you are expecting from the push notification.
Something like this:
JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
Log.d(TAG, json.getString("alert").toString());
if (json.has("title")) {
notificationTitle = json.getString("title").toString();
}
if (json.has("alert")) {
notificationAlert = json.getString("alert").toString();
}
if(json.has("uri")) {
notificationURI = json.getString("uri");
}
Then set appropriate contentTitle
and contentText
in notification
NotificationCompat.Builder builder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(notificationAlert)
.setContentText(notificationAlert);
Hope this helps!
