check your all xml layouts or any resource from drawable which may be causing this issue. if you can share the code i may help you. — Sanket Patel, Jan 22 '20 at 06:15
Does your AS point to a specific error or file? If u are using image/png/xml resources as image res or background, make sure they do exist in your drawable folder. — private static, Jan 22 '20 at 08:03
@AliEid it does not point to any specific error, and i am using the images already present on android studios. — SANJAY KASHYAP, Jan 22 '20 at 08:26
Try adding your own images to test it. Use a single image in all places to check if this is the problem — private static, Jan 22 '20 at 08:34
if this xml you've shared is exact then close the imageview and linear layout. else try to remove styles for a while and test the code. check if your style is not using a resource which is not available or corrupted. — Sanket Patel, Jan 22 '20 at 09:32
@SanketPatel if this was the issue, the compiler should have complained about them. I mean he may have posted them here wrongly — private static, Jan 22 '20 at 12:20
did u try removing styles and tested the app? as i don't see any other issues in the layout that may cause you this error other than styles if they're old or incompatible. — Sanket Patel, Jan 24 '20 at 06:47
@SanketPatel sir please help in my other question. i need help asap. — SANJAY KASHYAP, Jan 24 '20 at 10:05
@SanketPatel bro, my error is solved, but now it shows new error: Cannot fit requested classes in a single dex file (# methods: 76697 > 65536) — SANJAY KASHYAP, Jan 24 '20 at 10:53
