应用程序请求权限时崩溃

Question

我需要捕获设备的IMEI和IMSI以及您已经知道的，这需要一个权限"android.permission.READ_PHONE_STATE"。发生在上升此对话框窗口向用户请求此权限时，我的应用程序已停止。如何解决？

     @SuppressLint("MissingPermission")
        public void ListarApps(View view) throws PackageManager.NameNotFoundException {

            String myDeviceModel = android.os.Build.MODEL;
            String myDeviceProduct = android.os.Build.MANUFACTURER;
            String myVersion = Build.VERSION.RELEASE;
            System.out.println("Manufacturer: " + myDeviceProduct + " - Model: " + myDeviceModel + " - Android: " + myVersion);

            // Code For IMEI AND IMSI NUMBER ("android.permission.READ_PHONE_STATE")

            final int MY_PERMISSIONS_REQUEST_READ_PHONE_STATE = 999;

            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.READ_PHONE_STATE}, MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);


            String serviceName = Context.TELEPHONY_SERVICE;
            TelephonyManager m_telephonyManager = (TelephonyManager) getSystemService(serviceName);

            String IMEI, IMSI;

         /*   IMEI = m_telephonyManager.getDeviceId();
            IMSI = m_telephonyManager.getSubscriberId();  

     System.out.println("IMEI: " + IMEI);
     System.out.println("IMSI: " + IMSI); */
}

Answer 1

好的，因为我理解您的代码，您首先需要检查是否授予权限然后获取设备ID的wirte代码

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
                != PackageManager.PERMISSION_GRANTED) {
            // ask user permission 
        } else {
   // READ_PHONE_STATE permission is already been granted.
            TelephonyManager mngr = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
            IMEI = mngr.getDeviceId();                    
        }

您还需要覆盖OnRequestionResult

    @Override
        public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
                    if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// READ_PHONE_STATE permission is already been granted.
                TelephonyManager mngr = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
                IMEI = mngr.getDeviceId();  
    }
    }

Answer 2

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
                != PackageManager.PERMISSION_GRANTED) {
            // ask user permission 
        } else {
   // READ_PHONE_STATE permission is already been granted.
            TelephonyManager mngr = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
            IMEI = mngr.getDeviceId();                    
        }
