Make a Phonecall in Android

How to make a phone-call in Android


Here is the code:


private void call() {
   try {
       Intent callIntent = new Intent(Intent.ACTION_CALL);
       callIntent.setData(Uri.parse("tel:123456789"));
       startActivity(callIntent);
   } catch (ActivityNotFoundException activityException) {
       Log.e("phonecall", "Call failed", activityException);
   }
}

Manifest file:


    <uses-permission android:name="android.permission.CALL_PHONE"/>

    <uses-permission android:name="android.permission.READ_PHONE_STATE" />



Here is the code after completing the call activity it will return back to your application:



PhoneCallListener phoneListener = new PhoneCallListener();
TelephonyManager telephonyManager = (TelephonyManager) this .getSystemService(Context.TELEPHONY_SERVICE);



private class PhoneCallListener extends PhoneStateListener {
 
private boolean isPhoneCalling = false;


@Override
public void onCallStateChanged(int state, String incomingNumber) {

if (TelephonyManager.CALL_STATE_RINGING == state) {
//  ringing state

}

if (TelephonyManager.CALL_STATE_OFFHOOK == state) {
//active state
isPhoneCalling = true;
}

if (TelephonyManager.CALL_STATE_IDLE == state) {
//idle state


if (isPhoneCalling) {

Intent intent = getBaseContext().getPackageManager()
.getLaunchIntentForPackage(
getBaseContext().getPackageName());
intent .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent );

isPhoneCalling = false;
}

}
}
}
