Hey everyone
I just started writing the beginning of a program to get an IMSI number,
Upon setting the event of when pressing the button and using TelephonyServices
I get an error telling me I should give a warning before this action, and so I did choose that option, but now I got an error next to the word: "this"..
Does anybody know why?
enter code here
package com.example.yakir.myapplication;
import android.Manifest;
import android.content.Context;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.telephony.TelephonyManager;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private Button button;
TextView textView;
TelephonyManager td;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.checkConnectionButton);
textView = (TextView) findViewById(R.id.chechConnectionText);
td = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
textView.setText("IMSI number: " + td.getSubscriberId());
}
});
}
}
