In android/res/drawable-* there are 3 folders there, for 3 icon sizes:
ldpi, mdpi and hdpi
The format is PNG

Just make your main form (the first from the auto-creation list) a
splash form. There put a image+text or something like that and a timer
with 5 interval for example. In the timer OnTimer event execute
whatever long code you want and in the end load the next form and
disable the timer.

(often the about button) ?
Button presses are sent to the events OnKeyDown, OnKeyUp and
OnKeyPress.

About the about button I am not sure if it is already in the list of
supported items, you can just press it and see if anything shows in
the logcat. Also could you take a photo of a device and circle it in
read and post the image here? For I don't remember any "about" button
in the devices I know. The buttons I remember are:
*Menu button
*Search button
*Home button
*Back button
*Camera button
*Volume
*Trackball click

Sorry it was the Menu button, thaht I can add an About icon in there
(is it possible ?)

How do I add this function and how do I add a button there ?

Many thks

EDIt :moreover, I think the form stretch itself to the screen of the
user ? Am I right ? Just sometimes is the font not so readable.... It
seems that the font is proportionnal to the button. Could you explain
how the font work in a button ? thks.

PS : I need to add the lazarus icon, text about lazarus and credit for
people who help me in this.

The menu button will show the TMainMenu object attached to the current
form.

Images in menus are not currently supported, but I'll add it to my
ToDo.

Put a TMainMenu in your form.

Yes, the form and everything else is adjusted to fit the screen, but
it is not a stretch. All elements are redrawn. However I do have seen
sometimes some elements which were not updated, I need to check again
if everything is being invalidated in a form rotation as it should,
but I think that I already fixed this problem. Could you show a series
of screenshots showing the problem?

Make an about form and use TImage and TLabel

Works ! No image needed after all...

I used

QuoteLCLIntf.MessageBox(0, 'Text', 'Caption', 10000)
(thanks to Paul) To have a TextBox without button

QuoteCould you show a series of screenshots showing the problem?I
though I could modify the button or the font directly in IDE (I know
you told me to modify customdrawn_android.pas). So the result in
ANdroid was awful. I revert all button to default and everything is
fine now.

thks !
