應用程序在請求 READ_PHONE_STATE 權限時因 IllegalStateException 崩潰

Question

我需要捕獲設備的 IMEI 和 IMSI 以及您如何知道，這需要權限"android.permission.READ_PHONE_STATE" 。 發生這種情況時，當這個對話框窗口出現向用戶請求此權限時，我的應用程序停止了。 怎么解決？

@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，我了解您的代碼，您首先需要檢查是否授予權限，然后為getDeviceId編寫代碼

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();
}

您還需要覆蓋onRequestPermissionsResult

@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();                    
        }
