I am new to android studio. I have tried all the answers I could get none worked. I changed my gradle plugin to 3.1.1 and lower is still the same thing. I have clean build and invalidate cache/reset.

Do I have to install a lower android studio. Why is this happening for a new project? Andriod studio 3.2.1

Answer 1

@Openwell thanks a lot. you save my day!

I found the source of the problem. I noticed that the andriod.jar file in C:\Users**\AppData\Local\Android\Sdk\platforms\android-28 was missing, the file was 0kb. which shouldn't be so. So I reinstalled the Android SDK platform and sources by uninstalling it from SDK Manager and installed it back. then the problem was solved.

Answer 2

I just changed the compiled version to API level to which I have downloaded in the SDK Manager. For me in File=>Project Structure, the compiled version is set to 29 which I haven't downloaded SDK. So I changed it to 28 which I have downloaded.Then it worked.
