It’s really simple. Here’s some code sequence.
just connect the following to the beginplay of your character Blueprint
Note the delay nodes - I just added these so that screenshots are taken cleanly and to avoid that android might get messed up when second shot appears immediately while first one is still running - did not test that, but just to be sure…
Here’s a link on blueprintue, where you can copy the code.
Start your app, wait until done, stop.
Now you can use the adb debug bridge with pull command to get the screenshots. Standard screenshots go into Saved/Screenshots/Android directory
E:\tmp>adb pull /sdcard/UE4Game/Minimal2/Minimal2/Saved/Screenshots/Android/ScreenShot00000.png ScreenShot00000.png
/sdcard/UE4Game/Minimal2/Minimal2/Save...d. 20.0 MB/s (1098814 bytes in 0.052s)
E:\tmp>
Note, that BugScreenshots go into Saved/BugIt/Android directory
E:\tmp>adb pull /sdcard/UE4Game/Minimal2/Minimal2/Saved/BugIt/Android/BugScreenShot_00000.png BugScreenShot_00000.png
