"getScreenWidth" and "getScreenHeight" Sometimes you need to know the
exact screen size to make adjustments.

"getSystemVersionString" shows us the android version in text format
for example: '6.0' instead of 23 which would be the same
"getSystemVersion"

Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i     public
int getScreenWidth( ){        return
this.controls.activity.getResources().getDisplayMetrics().widthPixels;
           }        public int getScreenHeight( ){              return
this.controls.activity.getResources().getDisplayMetrics().heightPixels
;    }        public String getSystemVersionString(){        return
android.os.Build.VERSION.RELEASE;    }

look at the dot completion proposals for `screen.` There's already all
what you need.

`Forms` must be in the `uses`. Then `screen.width`, `screen.height`
etc. Try to learn and explore the LCL before suggesting next  time.
Lazarus is over 10 years old so you can imagine that tons of stuff are
already there.

What you told me is the first thing I tried, but Android does not
return the real value of the screen, I always got the same resolution
of 320x648 on 720x1280 screens and 540x960 screens. Just get the real
value using the functions described above, try it and tell me.

Greetings.

Ps. I've been programming in Delphi for more than 20 years.

QuoteForms must be in the `uses`.....

some misunderstanding here: LAMW "jForm" ... not LCL "Form"
compatible.

Indeed i've missed the fact that OP's posted in the Android subforum.
