Question

I have a ussd code on a button.I add CALL_PHONE permissions in manifest. I use the sdk version (23). This code does not work properly.

Basically what I should do?Thanks.

I have following error:

Answer 1

In Android Version > 23, you have to ask permission at run-time. You did not asked user about CALL_PHONE at run time and App crashed.

Something like this:

Learn more about asking permission at run time.

Answer 2

From SDK version 23 and above you have to ask for runtime permission to the users.It is mandatory to ask from API level 23 and above.

You can use this code and if boolean is true then it will allow you to call.

before this line

if (requestCallPhonePermission(this)) {
ActivityMain.this.startActivityForResult(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussd)),1);
}  


@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public static boolean requestCallPhonePermission(final Context context) {
    if (Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        String callPhonePermission = Manifest.permission.CALL_PHONE;
        int hasPermission = ContextCompat.checkSelfPermission(context, callPhonePermission);
        final String[] permissions = new String[]{callPhonePermission};
        if (hasPermission != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions((Activity) context, permissions, PERMISSION_REQUEST_CALL_PHONE);
            return false;
        } else {
            return true;
        }
    }
    return true;
}

and in same activity to receive permission put this as well.

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {
        case PERMISSION_REQUEST_CALL_PHONE:
            if (grantResults.length <= 0 || grantResults[0] != PackageManager.PERMISSION_GRANTED) {
                Snackbar snackbar = Snackbar.make(CoordResident, R.string.permission_goto_setting, Snackbar.LENGTH_LONG);
                snackbar.setAction("Settings", new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        // open settings to enable permisions 
                    }
                });
                snackbar.show();
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}
