App Crashes on Button Click that was supposed to send a call instantly - android-studio

Question

I have set up the button such a way that upon the click of a button it will send a call. when the button is clicked the app crashes. Please Help me debug this. Please suggest if there are alternative ways i can code a button to send a call directly upon clicking on it. I have granted permission in the settings as well.
package com.example.allegiant;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import android.Manifest;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
Button dial;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dial = findViewById(R.id.dial);
}
public void onDialButton(View view) {
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tell:12345678"));
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
return;
}
startActivity(intent);
}
}
Here is the logcat

Answer 1

Try adding READ_PHONE_STATE permission in manifest as well as ask it before click.
android.permission.READ_PHONE_STATE
Also surround your code inside click with try - catch having ActivityNotFoundException handling
