Need to add require permission in Android Manifest.xml file
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
Now need to Allow user permission at run time in your AppCompatActivity
public void FindIME() {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// your READ_PHONE_STATE permission yet not granted.
DevicePermission();
} else {
// your READ_PHONE_STATE permission is already been granted.
ActivityCompat.requestPermissions(FlashScreen.this, new String[]{Manifest.permission.READ_PHONE_STATE}, PERMISSION_READ_STATE);
GetIME();
}
}
Here we need to ask for user permission
private static final int MY_PERMISSIONS_REQUEST_READ_PHONE_STATE = 0;
private void DevicePermission() {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.READ_PHONE_STATE)) {
new AlertDialog.Builder(FlashScreen.this)
.setTitle("Permission Request")
.setMessage(getString(R.string.permission_read_phone_state_rationale))
.setCancelable(false)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
//re-request
ActivityCompat.requestPermissions(FlashScreen.this,
new String[]{Manifest.permission.READ_PHONE_STATE},
MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
}
})
.setIcon(R.drawable.ic_login)
.show();
} else {
// READ_PHONE_STATE permission has not been granted yet. Request it directly.
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE},
MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
}
}
public void GetIME() {
String deviceUniqueIdentifier = null;
TelephonyManager tm = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
if (null != tm) {
deviceUniqueIdentifier = tm.getDeviceId();
}
if (null == deviceUniqueIdentifier || 0 == deviceUniqueIdentifier.length()) {
deviceUniqueIdentifier = Settings.Secure.getString(this.getContentResolver(), Settings.Secure.ANDROID_ID);
}
IME_Device = deviceUniqueIdentifier;
Log.i("Device Ime", "Value--------->" + IME_Device);
}
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_READ_PHONE_STATE: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission granted!
GetIME();
} else {
// permission denied
Toast.makeText(mContext, "Need to allow Read Phone state ..", Toast.LENGTH_LONG).show();
}
}
break;
case PERMISSION_READ_STATE: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission granted!
} else {
// permission denied
Toast.makeText(mContext, "Need to allow Read Phone state ..", Toast.LENGTH_LONG).show();
}
}
break;
}
}
