¿Cómo se puede comprobar el permiso en tiempo de ejecución sin lanzar SecurityException?

Esta es otra solución también

PackageManager pm = context.getPackageManager();
int hasPerm = pm.checkPermission(
    android.Manifest.permission.WRITE_EXTERNAL_STORAGE, 
    context.getPackageName());
if (hasPerm != PackageManager.PERMISSION_GRANTED) {
   // do stuff
}

También puedes usar esto:

private boolean doesUserHavePermission()
{
    int result = context.checkCallingOrSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE);
    return result == PackageManager.PERMISSION_GRANTED;
}

Como Google documentación :

// Assume thisActivity is the current activity
int permissionCheck = ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.WRITE_EXTERNAL_STORAGE);

Compartir mis métodos en caso de que alguien los necesite:

 /** Determines if the context calling has the required permission
 * @param context - the IPC context
 * @param permissions - The permissions to check
 * @return true if the IPC has the granted permission
 */
public static boolean hasPermission(Context context, String permission) {

    int res = context.checkCallingOrSelfPermission(permission);

    Log.v(TAG, "permission: " + permission + " = \t\t" + 
    (res == PackageManager.PERMISSION_GRANTED ? "GRANTED" : "DENIED"));

    return res == PackageManager.PERMISSION_GRANTED;

}

/** Determines if the context calling has the required permissions
 * @param context - the IPC context
 * @param permissions - The permissions to check
 * @return true if the IPC has the granted permission
 */
public static boolean hasPermissions(Context context, String... permissions) {

    boolean hasAllPermissions = true;

    for(String permission : permissions) {
        //you can return false instead of assigning, but by assigning you can log all permission values
        if (! hasPermission(context, permission)) {hasAllPermissions = false; }
    }

    return hasAllPermissions;

}

Y para llamarlo:

boolean hasAndroidPermissions = SystemUtils.hasPermissions(mContext, new String[] {
                android.Manifest.permission.ACCESS_WIFI_STATE,
                android.Manifest.permission.READ_PHONE_STATE,
                android.Manifest.permission.ACCESS_NETWORK_STATE,
                android.Manifest.permission.INTERNET,
        });

Debe verificar los permisos de la siguiente manera (como se describe aquí Permisos de Android):

int result = ContextCompat.checkSelfPermission(getContext(), Manifest.permission.READ_PHONE_STATE);

Luego, compare su resultado con:

result == PackageManager.PERMISSION_DENIED

O:

result == PackageManager.PERMISSION_GRANTED

El código que funciona bien para mí es :-

  final int MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE = 102;
  if ((ContextCompat.checkSelfPermission(getActivity(),Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED)) {

                requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                        MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE);
            } else {
        // user already provided permission
                // perform function for what you want to achieve
     }

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {

    boolean canUseExternalStorage = false;

    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE: {
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                canUseExternalStorage = true;
            }

            if (!canUseExternalStorage) {
                Toast.makeText(getActivity(), "Cannot use this feature without requested permission", Toast.LENGTH_SHORT).show();
            } else {
                // user now provided permission
                // perform function for what you want to achieve
            }
        }
      }
 }
