How to use code programming to obtain the IMEI / ESN number of the device, but in Android > 6

How to find / get IMEI number > 6 in Android programmatically

Note: I added read to the androidmanifest. XML file_ PHONE_ State permission

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

And in mainactivity

TelephonyManager manager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String deviceid = manager.getdeviceid();

//Device Id is IMEI number

Log.d("msg", "Device id " + deviceid);

resolvent:

Note: you need runtime permissions

I added read to the androidmanifest. XML file_ PHONE_ State permission

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

In mainactivity:

private static final int PERMISSIONS_REQUEST_READ_PHONE_STATE = 999;

private TelephonyManager mTelephonyManager;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
            != PackageManager.PERMISSION_GRANTED) {
        requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE},
                PERMISSIONS_REQUEST_READ_PHONE_STATE);
    } else {
        getDeviceImei();
    }
....

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
                                       int[] grantResults) {
    if (requestCode == PERMISSIONS_REQUEST_READ_PHONE_STATE
            && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        getDeviceImei();
    }
}

private void getDeviceImei() {

    mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    String deviceid = mTelephonyManager.getdeviceid();
    Log.d("msg", "DeviceImei " + deviceid);
}
