Parse SDK在android中为推送通知实现自定义BroadcastReceiver

Question

我试图在Android上开始使用Parse推送通知,但我找不到任何方法来实现我自己的BroadcastReceiver,它会执行响应推送通知的操作.

在他们的"入门"中,他们给出了一个程序示例,其中接收器和intent服务包含在jar文件中(并且未在代码中实现,因此我可以尝试使用它).这里也提出了类似的问题,但它已经两年了,答案有11个问题.

还有一些其他的博客文章,例如在这里,但没有一个正常工作(该链接中的一个是两年).

所以请建议一步一步地实施同样的方法.

编辑:

我按照droidx的建议尝试了代码.但它不起作用.我正在发送我的AndroidManifest.xml(其余代码完全按照他的建议):

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

这是一个例子!

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());
        }

    }
}

按照本指南,将接收器的android名称替换为自定义广播接收器的路径

<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>

在您的应用程序类中,请确保已按此订阅Parse Push

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);
                }
            }
        });

更新:

上述广播接收器希望从解析仪表板发送一个json对象通知,通常由三个名称值对组成:

{ "alert": "Alert message", "title": "Title", "uri": "bla bla" } 

当你只使用普通字符串时,例如:hello world!在解析推送仪表板,内部它只作为警报标签.这样的事情:{"alert" : "hello world!, "title" = null/"", "uri" = null/""}

上面的广播接收器代码没有这个空检查,所以它被捕获到异常没有title/uri的catch.

因此,您可以根据推送通知的期望添加一些空检查.

像这样的东西:

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");
            }

然后设置适当的contentTitle,并contentText在通知

 NotificationCompat.Builder builder =
                    new NotificationCompat.Builder(context)
                            .setSmallIcon(R.mipmap.ic_launcher)
                            .setContentTitle(notificationAlert)
                            .setContentText(notificationAlert);

希望这可以帮助!
