@lve0200 ====  
or, using your code (some modifs: creating a runnable)

```auto
import android.app.Activity;
import android.content.Context;
import android.content.DialogInterface;
import android.app.AlertDialog;
import android.widget.EditText;
import android.os.Looper;

String et = "";
Context ctx;
Activity act;

void setup(){
  size(800,600);
  orientation(LANDSCAPE);
  act = this.getActivity();
  ctx = this.getActivity().getApplicationContext();
   showAddItemDialog();
   Looper.prepare();
   
}

private void showAddItemDialog() {
  this.getActivity().runOnUiThread(new Runnable() {
    //@ Override
      public void run() {
    final EditText taskEditText = new EditText(ctx);
    AlertDialog dialog = new AlertDialog.Builder(act)
        .setTitle("Altimeter")
        .setMessage("Set Altimeter")
        .setView(taskEditText)
        .setPositiveButton("Add", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                et = String.valueOf(taskEditText.getText());
            }
        })
        .setNegativeButton("Cancel", null)
        .create();
    dialog.show();
}
  });
};

void mouseReleased(){
  println("Click");
  showAddItemDialog();
}

void draw() {

}

doesn’t work, crash after click or already in setup, if the showAddItemDialog statement is in there.  
puh,  
I’m programming since 1976, nowadays in VisualStudio C,C++, Cross for UNIX, Windows, MS R-open and I tell you, I have never come across something like Android!  
here’s my code, now: compiles OK, runtime error attached:  
It must be mouseReleased, mousePressed also doesn’t do anything.

```auto
Activity act;
Context mC;
FrameLayout fl;
String et;

private void showAddItemDialog() {
  this.getActivity().runOnUiThread(new Runnable() {
    //@ Override
      public void run() {
    final EditText taskEditText = new EditText(mC);
    AlertDialog dialog = new AlertDialog.Builder(mC)
        .setTitle("Altimeter")
        .setMessage("Set Altimeter")
        .setView(taskEditText)
        .setPositiveButton("Add", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                et = String.valueOf(taskEditText.getText());
            }
        })
        .setNegativeButton("Cancel", null)
        .create();
    dialog.show();
      }
  });
}

void mouseReleased(){
  println("Click");
  showAddItemDialog();
}

void setup(){ // Partie graphiques fixe
size (1024,768,P2D); // size 
orientation(LANDSCAPE);
background(255,0,0);

act = this.getActivity();
mC = this.getActivity().getApplicationContext();
Looper.prepare();

```

```auto

No, it doesn’t! Unless totally blind, I copied your code 100% OK.  
I found the explanations, why it doesn’t work, but I am unable to understand it.  
Please look here:  
[https://stackoverflow.com/questions/5796611/dialog-throwing-unable-to-add-window-token-null-is-not-for-an-application-wi](https://stackoverflow.com/questions/5796611/dialog-throwing-unable-to-add-window-token-null-is-not-for-an-application-wi)  
Hence I added this line of code:  
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE\_SYSTEM\_ALERT);  
I get a warning:  
TYPE\_SYSTEM\_ALERT is depreciated, but it works now, after I also granted the App permission: SYSTEM\_ALERT\_WINDOW  
´´´  
Just the permission is not enough, this new code line is necessary.  
Here the complete module:

```auto
private void showAddItemDialog() {
  this.getActivity().runOnUiThread(new Runnable() {
    //@ Override
      public void run() {
    final EditText QNH_Edit = new EditText(mC);
    AlertDialog dialog = new AlertDialog.Builder(mC)
        .setTitle("Altimeter")
        .setMessage("Set Altimeter")
        .setView(QNH_Edit)
        .setPositiveButton("Add", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                et = String.valueOf(QNH_Edit.getText());
            }
        })
        .setNegativeButton("Cancel", null)
        .create();
    dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
    dialog.show();
      }
  });
}

```

what should I do wrt. the depreciated FLAG?  
Testing now on a LG g Pad 7 device w/ Android 5.

@lve0200 === as for the deprecated flag you can use instead TYPE\_APPLICATION\_OVERLAY  
(but requires API 26)  
as for the permission it remains (weird!) the same  
i see that you are working with 5; that is not a problem but think that after (6.0) permissions have to be required on runtime (Manifest does not work); so you have to write some if else statement getting the build and add methods for getting permissions on runtime if…

@lve0200 ===  
another flag that you add to the window:  
WindowManager.LayoutParams.FLAG\_KEEP\_SCREEN\_ON;  
( be prudent with this flag && at least get rid of it when the user leaves: you must clear()it)

Hi,  
I don’t really know, how and where to put this. I tried this in setup() and in draw()  
getWindow().addFlags(WindowManager.LayoutParams.FLAG\_KEEP\_SCREEN\_ON);  
and got always that:  
FATAL EXCEPTION: GLThread 332  
Process: processing.test.miniefis, PID: 6614  
android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.  
One of my issues is, that 99% of all example in the internet use R.layout.activity\_main

</div>

@lve0200 ===  
that is absolutely normal: the view was created by MainActivity thread and so you cannot modify it without creating a runnable:

```auto
import android.view.WindowManager;
void setup(){
  
  size(800,600);
  orientation(PORTRAIT);
  KeepScreen();
}

private void KeepScreen() {
  this.getActivity().runOnUiThread(new Runnable() {
   
      public void run() {
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
      }
  });
}

```
