In AndroidManifest.xml

<receiver android:name=".BootUpReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>

Create Java File named with BootUpReceiver

public class BootUpReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
         if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
              //Do your coding here...
         }
    }
}
