String[]PERMISSIONS_STORAGE={Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.WRITE_EXTERNAL_STORAGE};
if(ActivityCompat.checkSelfPermission(MainActivity.this,Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED)
{ActivityCompat.requestPermissions(MainActivity.this,PERMISSIONS_STORAGE,1);
}
