Sending explicit Broadcasts is some what same as sending explicit intent

We can send/receive  broadcasts inside the app and From other apps

----------------------------------------------------------------------------------------

USING EXPLICIT BROADCAST INSIDE THE APP :

Step 1]  Create a Broadcast receiver class .

Broadcastreceiverrrclass.java

package com.deepesh.broadcastapp3;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;

public class Broadcatsreceiverrr extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

            Toast.makeText(context, "Broadcast Received !", Toast.LENGTH_SHORT).show();
            Log.d("KEYY","BROADCAST RECEIVED !");

    }
}

Step 2] Inside the Main Activity or anywhere inside the App , form where you want to send the broadcast , create a EXPLICIT intent. 

Pass the intent object , the context and the Broadcastreceiverr class you want to send broadcast too.

then use the sendBroadcast()

//user clicks on button to execute this method
public void SendBroadcast(View view) {

    //creating explicit intent
    Intent intent = new Intent(this,Broadcatsreceiverrr.class);

    //Send the broadcast.
    sendBroadcast(intent);
}

Step 3] Now we need to register the Broadcastreceiver class as receiver inside the Manifest file.

(If you dont do this your broadcats wont be received)

 <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        tools:ignore="ExtraText">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
         //register your broadcatsreciver class a receiver
        <receiver android:name=".Broadcatsreceiverrr"/>
    </application>

</manifest>

Thats it.
