Android Question how to invoke system screen shot

[Zeev Goldstein]

hi,

is there a way to invoke the system screenshot operation programmatically?

i need to take my activity's screenshot and i want it to be store in screenshots folder as if it was taken by the operating system, exactly as if the user pressed the screenshot button or slided the screen or any other way

thanks...

Make a Panel (declared as B4XView) as the first view in your Layout.
Make it big as the whole layout/display.
Put yout layout inside this panel.
When you need the Screenshot call

dim b as B4XBitmap = Panel1.Snapshot    'Supposing the Panel is called Panel1

and then save the bitmap where you need.
This is for Activity project, that should be avoided nowadays.
If you make a B4XPages project it will be even more simple.
No need to make all the things about the transparent panel.
Just call

dim b as B4XBitmap = Root.Snapshot

i'm not sure it is what i was looking for
i need to activate the os screenshot so it will be transparent for the app and store the image in screenshot folder
my app is an existing activity app and i do not want to start turning it upside down now
so what i need is - how to activate the os print screen as if the user did it but programmatically

I think that it's not possible to invoke the System Screenshot.
But I could be wrong.
Every day that pass it looks like the OS is the King (ok, that's normal) and our apps are Unwanted Intruders.

Take a Screenshot with Inline Java Code

I have tested this on an Android 7.0 device only - take a screenshot of your activity. You need to enable the JavaObject library to make use of it. @JordiCP solved my initial problem here (thanks @JordiCP)...

Not sure if it will work with SDK = 31 but you can try. If it does work you need to handle the bitmap I.e convert it to PNG and save it. The do with the png whatever it is you want to do with it.
