don't limit component

hi i am making app to control car security system using Arduino. but i get problem hope MIT team limited component to  adding blocks. when i try to compile my app i got error.(please check attachment i added screen shot).  but after i delete few blocks i can compile project. again if i add components to block again can't compile project, same issue. Hope they limited components. please MIT team can you fix this issue we can make good app using your software. thank you very much.

Can you give us a sense of how large your blocks file is? In the past we've seen that people who build large projects with many if-else blocks rather than taking advantage of mutators can result in the DX step (Android compilation) running out of memory. This might explain why if you add/remove a few blocks it works/doesn't work. Based on your vertical scroll bar my guess is that the project is rather large and may need some optimization for it to work without crashing the Android tools.
