i've tried to solve this issue by checking answers of this quesiton: My app is crashing in landscape mode but it didnt work out for me, it still crashes, i have two different styles for portrait and landscape, this is my portrait design: and this is how it should look like in landscape the error didnt happen when i added

android:configChanges="orientation|screenSize|keyboardHidden"

to manifest inside the home activity but the problem is it didnt show up the landscape design i made, instead it just rotated the portrait one directly, i removed the attribute screensize and the app crashed again, I have no clue how to solve this, please help me. and thank you.

Answer 1

in case this error happens to anyone in the future, my problem was that I've declared a button in portrait mode and forgot to add it in landscape mode, a button which I've used in another activity so it kept returning null object reference
