}

private void Tablolar(){

}

private void Sorgula(String sorgu)
{

}

}

Can anyone help me about this issue pls?

Answer 1

you missed super.onCreate(savedInstanceState). Also

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

must be called before setContentView
