Question

我开发了一款使用解析推送通知服务的应用。通过整个过程，我在GenyMotion上测试了应用程序，同时在android studio中使用它。

解析推送工作正常。

但是现在开发之后，当我在运行Android 4.1.2的Micromax Canvas A116 HD中尝试使用相同的应用程序时，我只是没有得到任何推送通知。

我甚至在广播接收器中设置了BP，它甚至没有打破过它。

genyMotion中运行的同一个应用程序如何获取通知。

以下是应用中的代码：

MyBroadcastReceiver：

import android.content.Context;
import android.content.Intent;

import android.graphics.BitmapFactory;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

import com.parse.ParsePushBroadcastReceiver;

import org.json.JSONException;
import org.json.JSONObject;

import java.util.Random;

import Database.Database;
import Database.NoticeInformation;

/**

 */
public class MyBroadcastReceiver extends ParsePushBroadcastReceiver {
    @Override
    public void onPushReceive(Context context, Intent intent) {

        JSONObject json = null;

        Log.i("TAG", "Push Received");
        String data="", channel, action, f_name = "", n_id  = "0", n_type = "", n_head = "", n_file = "";
        try{
            action = intent.getAction();
            channel = intent.getExtras().getString("com.parse.Channel");
            data = intent.getExtras().getString("com.parse.Data");
            json = new JSONObject(data);
        }
        catch(Exception ex){
            ex.printStackTrace();
        }

        try {
            n_type = json.getString("N_TYPE");
            n_head = json.getString("N_HEADER");
            n_file = json.getString("N_FILE");
        }catch (JSONException e){
            e.printStackTrace();
        }


        //Save Information to Database
        NoticeInformation ninfo = new NoticeInformation(0, n_type, n_head, +n_file, 0, 0);
        Database db = new Database(context);
        long r_id = db.insertIntoNoticeStorage(ninfo);

        Intent launchIntent = new Intent(context, WebViewActivity.class);
        launchIntent.putExtra("Link", n_file);
        launchIntent.putExtra("N_ID", String.valueOf(r_id));

        Bitmap icon = BitmapFactory.decodeResource(context.getResources(), R.drawable.e_icon);

        Notification notification = new NotificationCompat.Builder(context)
                .setContentTitle("Push Notification")
                .setContentText("A New Notice Was Published.")
                .setContentIntent(pi)
                .setAutoCancel(true)
                .setLargeIcon(icon)
                .setSmallIcon(R.drawable.e_icon)
                .build();

        NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
        nm.notify(1, notification);
    }
}

我根本无法理解发生了什么以及如何解决这个问题。这与android版本有关吗？我没有任何具有最新android的设备，但在Genymotion上，该应用程序在Android 4.1.1中工作（推送已收到）。

需要一些帮助！

Answer 1

我找到了问题的解决方案。我在android 4.1.2,4.3中测试了这个。

工人阶级如下：

package com.pchakraverti.enotice_new;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.support.v7.app.NotificationCompat;
import android.util.Log;

import org.json.JSONException;
import org.json.JSONObject;

import java.util.Random;

import database.*;

/**

public class MyBroadcastReceiver extends BroadcastReceiver {

    JSONObject json = null;

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

        Log.i("TAG", "Push Received");
        String data="", channel, action, n_id  = "0", n_type = "", n_head = "", n_file = "";;
        try{
            action = intent.getAction();
            channel = intent.getExtras().getString("com.parse.Channel");
            data = intent.getExtras().getString("com.parse.Data");
            json = new JSONObject(data);
        }
        catch(Exception ex){
            ex.printStackTrace();
        }

        try {
            n_type = json.getString("N_TYPE");
            n_head = json.getString("N_HEADER");
            n_file = json.getString("N_FILE");
        }catch (JSONException e){
            e.printStackTrace();
        }

        NoticeInformation ninfo = new NoticeInformation(0, n_type, n_head, n_file, 0, 0);
        Database db = new Database(context);
        long r_id = db.insertIntoNoticeStorage(ninfo);

        Intent launchIntent = new Intent(context, WebViewActivity.class);
        launchIntent.putExtra("Link", n_file);
        launchIntent.putExtra("N_ID", String.valueOf(r_id));
        PendingIntent pi = PendingIntent.getActivity(context, new Random().nextInt(), launchIntent, PendingIntent.FLAG_CANCEL_CURRENT);

        Bitmap icon = BitmapFactory.decodeResource(context.getResources(), R.drawable.e_icon);

        Notification notification = new NotificationCompat.Builder(context)
                .setContentTitle("A notice has been published!")
                .setContentText(n_head)
                .setContentIntent(pi)
                .setAutoCancel(true)
                .setLargeIcon(icon)
                .setSmallIcon(R.drawable.e_icon)
                .build();

        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notification.defaults |= Notification.DEFAULT_LIGHTS;

        NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
        nm.notify(1, notification);
    }
}

ParseBroacastReceiver完全失败。这怎么可能完美。

Answer 2

你为什么评论ParsePush.subscribeInBackground()？如果您删除此评论，此代码应该有效。我有一个与初始化和订阅完全相同的应用程序。（确保解析时应用程序设置上的“启用客户端启用”选项为“是”）。

Parse Push通知在Genymotion中有效，但在真实手机中不起作用
