Parse.com Android Push Notifications With Url - android

I am trying to integrate parse into my app with push notifications and have the notification display custom text and open the device's browser when I send a url to it.
The parse integration is fine(Thats the easy part) but where I am stuck is what to code for the integration for handling the json code sent by the parse interface and have the app translate it into the action I need done.
I know I will have to update the manifest file and the main activity class to accomplish this but I am stuck.

Add Manifest to
<receiver android:name="com.sample.app.android.recevier.PushNotificationRecevier" >
<intent-filter>
<action android:name="com.sample.app.android.SIMPLE_NOTIFICATION" />
</intent-filter>
</receiver>
Create One receiver Class
import org.json.JSONException;
import org.json.JSONObject;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class PushNotificationRecevier extends BroadcastReceiver{
String SimpleNotification="com.sample.app.android.SIMPLE_NOTIFICATION";
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equalsIgnoreCase(SimpleNotification)){
// Your Stuff
JSONObject jsonObject=new JSONObject(intent.getExtras().getString("com.parse.Data"));
}
}
}

what is the corresponding action for the "android.net.conn.CONNECTIVITY_CHANGE" on Android 7.0 and above?

I used a broadcast receiver to detect the wifi connection. it successfully works for the android Lolipop. but when I try to work with Pie(android 9) it is not working. I registered this broadcast in AndroidManifest.xml as follows.
<receiver android:name=".ExampleBroadcast">
<intent-filter>
<action android:name="android.net.wifi.WIFI_STATE_CHANGED"/>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
</intent-filter>
</receiver>
Example broadcast is my class which extended the broadcast receiver. it does works as follows.
package com.example.myapplication;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
import android.widget.Toast;
public class ExampleBroadcast extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
//required task
}
}
The above code works for the android 5 and not support for the android Pie. I want to know what is the correct registration criteria and what is the compatible action for the android.net.conn.CONNECTIVITY_CHANGE for above in android 7.
I know that in last versions of Android a lot of policies related to energy consumption and inter process communication have been changed; broadcast receivers have been changed too.
I find more usefull for you if you base your solution on a more consolidated answer like this one "How to Detect CONNECTIVITY_CHANGE", rather than on a newly written answer by me.
If the linked answer will not be usefull for you, I suggest to make a fast search on Google with keywords like for example "android pie connectivity change broadcast receiver" in order to find the best answer that suits your specific problem.

Why BroadcastReceiver don't work in React Native?

I try to develop an application that in the future can run a service, the service I want to run when I connect to a network.
At the moment I only need the receiver to print in the log (using react-native log-android) that has been connected or disconnected, or to visualise a toast with a message, all this in the background not in the foreground.
Try the following,
First I put the receiver in the AndroidManifest.xml
<application>
...
<receiver android:name="com.air_fighers_react_native.receiver.NetworkChangeReceiver">
<intent-filter>
<action android:name="android.net.conn.CONECTIVITY_CHANGE"/>
</intent-filter>
</receiver>
</application>
Even add the permissions:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Create the receiver folder in java > com > air_fighters_react_native > receiver and inside the NetworkChangeReceiver.java file with the following code:
package com.air_fighters_react_native.receiver;
import android.content.BroadcastReceiver
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class NetworkChangeReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Cambio de conexion.", Toast.LENGTH_LONG).show();
}
}
With this it is supposed that it should be enough, however when running the application there are no problems, but when I close the application and activate and deactivate the WiFi the toast message is not displayed, not even when I have the application in the foreground.
I have already tried changing receiver to:
<receiver android:name=".NetworkChangeReceiver">
And changing NetworChangeReceiver to the same level as MainApplication and MainActivity in folders.

FCM messaging with Realtime Firebase database

My app using FireBaserealtime database and storage.Now i am struck in the part of push notification FCM.Please help anyone how to do.Is there anyway,without open firebase console and send notification to devices?Or please help me to send notification by coding.
You can use Advance Rest client to send a notification to the device.
Use the link to add extension to chrome
https://chrome.google.com/webstore/detail/advanced-rest-client/hgmloofddffdnphfgcellkdfbfbjeloo
Notification will not receive when app kill, thus you need to Register Receiver to get Notification
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class OnBootBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{
Intent i = new Intent("com.android.pushnotify.MyFirebaseMessagingService");
i.setClass(context, MyFirebaseMessagingService.class);
context.startService(i);
}
}
add inside Manifest.xml(Application tag)
<receiver android:name="com.androidbash.androidbashfirebasepushnotify.OnBootBroadcastReceiver">
<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>

BroadcastReceiver is not starting Service in Android [duplicate]

In my Android application I want to run a Service without opening/running my application. For that I have extended BroadcastReciever class. But this BroadcastReceiver class is not being called from AndroidManifest.xml on BOOT_COMPLETE. So please tell what is the problem in my code? Or is there any other way to run a Service without opening my application? I have checked the control flow of my code and whole the code is working perfectly, the problem is that BroadcastReceiver is not being called.
Part of AndroidManifest.xml file:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<service android:name=".HelloService"
android:exported="false"/>
<receiver android:name=".MyBroadcastreceiver" android:enabled="true" android:exported="false">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
MyBroadcastreceiver.java class
package com.example.abc.project1;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class MyBroadcastreceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
/*this is not being called*/
Intent startServiceIntent = new Intent(context, HelloService.class);
context.startService(startServiceIntent);
}
}
Remove android:exported="false" from the <receiver>. That says you do not want anyone (other than yourself) sending a broadcast to this receiver. As a result, your receiver will be ignored by the system.
Beyond that, you also need an activity and to have run that activity before trying to reboot the device. You may already have that, but I thought that I would mention it for completeness.

Start application without activity, my Broadcast Receiver not work

In my app, I have a Broadcast Receiver for catching the message sent to my phone
<receiver
android:name="com.qmobile.ows.SMS_Receiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
If I start app with activity GUI, the BroadCast Receiver works normally.
I want to start my application without activity and do not show icon app, so I remove this code below from my activity
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
And after that, Broadcast Receiver do not work.
Please help me solve this problem.
This is because Android OS does not allow BroadcastReceiver to receive some important broadcast(android.provider.Telephony.SMS_RECEIVED must be one of it) if the appĀ“s process is not alive.It was designed to against the evil apps. If you have an activity running,your process is alive and so your receiver is allowed to receive the broadcast.
I think you can make a transparent activity and use startService to start a service in background,then finish the activity.As your service is running ,your process is alive,so the Android OS will let you to receive the broadcast.
For Android 3.1 and higher,
You have to launch one of your activities before any manifest-registered BroadcastReceiver will work.
See developer docs specifically the section -
Launch controls on stopped applications for android-3.1
If you are testing Broadcast receiver without an Activity then you should edit your run configuration.
When the Edit configuration dialog appears, select the Do not launch Activity option so that the activity is installed but not launched and click on the Run button
This will launch the application without activity.

Creating and Sending the Broadcast Intent
Having created the framework for the SendBroadcast application, it is now time to implement the code to send the broadcast intent. This involves implementing the broadcastIntent() method specified previously as the onClick target of the Button view in the user interface. Locate and double click on the SendBroadcastActivity.java file and modify it to add the code to create and send the broadcast intent. Once modified, the source code for this class should read as follows:
package com.ebookfrenzy.sendbroadcast;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.content.Intent;
import android.view.View;
public class SendBroadcastActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_send_broadcast);
}
public void broadcastIntent(View view)
{
Intent intent = new Intent();
intent.setAction("com.ebookfrenzy.sendbroadcast");
intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
sendBroadcast(intent);
}
.
.
.
}
Creating the Broadcast Receiver
In order to create the broadcast receiver, a new class needs to be created which subclasses the BroadcastReceiver superclass. Create a new project with the application name set to BroadcastReceiver and the company domain name set to com.ebookfrenzy, this time selecting the Add No Activity option before clicking on Finish.
Within the Project tool window, navigate to app -> java and right click on the package name. From the resulting menu, select the New -> Other -> Broadcast Receiver menu option, name the class MyReceiver and make sure the Exported and Enabled options are selected.
Once created, Android Studio will automatically load the new MyReceiver.java class file into the editor where it should read as follows:
package com.ebookfrenzy.broadcastreceiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MyReceiver extends BroadcastReceiver {
public MyReceiver() {
}
#Override
public void onReceive(Context context, Intent intent) {
// TODO: This method is called when the BroadcastReceiver is receiving
// an Intent broadcast.
throw new UnsupportedOperationException("Not yet implemented");
}
}
As can be seen in the code, Android Studio has generated a template for the new class and generated a stub for the onReceive() method. A number of changes now need to be made to the class to implement the required behavior. Remaining in the MyReceiver.java file, therefore, modify the code so that it reads as follows:
package com.ebookfrenzy.broadcastreceiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class MyReceiver extends BroadcastReceiver {
public MyReceiver() {
}
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Broadcast Intent Detected.",
Toast.LENGTH_LONG).show();
}
}
The code for the broadcast receiver is now complete.
Configuring a Broadcast Receiver in the Manifest File
In common with other Android projects, BroadcastReceiver has associated with it a manifest file named AndroidManifest.xml.
This file needs to publicize the presence of the broadcast receiver and must include an intent filter to specify the broadcast intents in which the receiver is interested. When the BroadcastReceiver class was created in the previous section, Android Studio automatically added a <receiver> element to the manifest file. All that remains, therefore, is to add an <intent-filter> element within the <receiver> declaration appropriately configured for the custom action string:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.ebookfrenzy.broadcastreceiver.broadcastreceiver" >
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<receiver
android:name=".MyReceiver"
android:enabled="true"
android:exported="true" >
<intent-filter>
<action
android:name="com.ebookfrenzy.sendbroadcast" >
</action>
</intent-filter>
</receiver>
</application>
</manifest>
With the manifest file completed, the broadcast example is ready to be tested.
add DEFAULT category in your intent filter
<category android:name="android.intent.category.DEFAULT" />
Ok. Here's what worked for me. I created a launcher activity. Removed the call to setContentView(R.layout.activity_main)
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main);
finish();
}
