Hello to all. Can anyone tell me how I can emit a simple beep?

1) Eat a lot of curried beans and cabbage
2) See this thread https://forum.lazarus.freepascal.org/index.php/topi

If I'm not mistaken, sysutils.beep doesn't work on android. It does
not give an error, but it does not give sound.
An example study about sound;
lazandroidmodulewizard-master\demos\GUI\AppSoundPoolDemo
You can find it on the way.

Or a hybrid application
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
ToneGenerator toneG = new ToneGenerator(AudioManager.STREAM_ALARM,
100);toneG.startTone(ToneGenerator.TONE_CDMA_ALERT_CALL_GUARD,
200);toneG.release();

Indeed for Android and nixes it is a stub. Empty procedure. You can
simply examine the rtl sources to see that.

Now it's clear why it wasn't working. I can use the above Java code in
my projects without any problems, but for other friends, master
jmpessoa can add this ability by adding the above java code (there is
definitely a method he knows better) to LAMW with a magic touch.

external 'msvcrt.dll' for win
external 'c' for Linux (..I think?..)
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
sound (freq:integer;duration:integer)cdecl external 'msvcrt.dll' name
'_beep'; beginsound(1000,200); //close to standard beepwriteln ('Press
enter to end . . .');readlnend.

But find a good icon for a new jToneGenerator component is very
difficult!

What about this one in attachment?  Some others suggestions?

Done!

NEW! component jToneGenerator    [tab "Android Bridge Extra"]

New! demo "AppToneGeneratorDemo1"


Thanks to All!
