Try this solution:
String DATA = "Html text....bla bla bla. Hellou world! čšřžěéá";
String HEADERHTML =
"<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">"
+"<html> <head> <meta http-equiv=\"content-type\" content=\"text/html; charset=utf-8\">"
+"</head> <body>";
String FOOTERHTML = "</body></html>";
WebView mWebView.loadData(HEADERHTML+DATA+FOOTERHTML,"text/html; charset=UTF-8",null);
Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with `checkPermission`) or explicitly handle a potential `SecurityException`
try {
// your code for example:
// LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// Criteria criteria = new Criteria();
// provider = locationManager.getBestProvider(criteria, false);
// locationManager.requestLocationUpdates(provider, 400, 1, this);
} catch (SecurityException e) {
e.printStackTrace();
}
// solution 1
ImageView imageView = (ImageView)findViewById(R.id.myimage);
imageView.setImageDrawable(null);
// or
imageView.setImageResource(0);
// solution 2 hide ImageView
imageView.setVisibility(View.INVISIBLE);
// solution 3 resize ImageView 0, 0
hImageViewSemafor.setLayoutParams(new LinearLayout.LayoutParams(0,0));
