Size screen issue

Question

for some reason, the application when reading the screen size getRealSize () began to give unreal sizes and 25 % less. I have a screen of 1920*1080, and gives 1440*810. When I start a project, the screen size shows correctly. But after the build for publication, this problem begins.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.activity_main); Point point = new Point();
    getWindowManager().getDefaultDisplay().getRealSize(point);}

Answer 1

You could use Dimension from Toolkit

Code:

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

System.out.println("Screen Width: " + screenSize.getWidth());

System.out.println("Screen Height: " + screenSize.getHeight());
