Installed Build Tools revision 28.0.3 is corrupted. How to fix this error

Question

When I make a new proyect, then Build-make project or try to Run App in an emulator with sdk api level 28 (Android 9.0 Pie), the Build Output window always show me this error:

Installed Build Tools revision 28.0.3 is corrupted. Remove and install again using the SDK Manager. 

I removed and reinstalled the sdk several times, and always gives me the same error. I'm using Android Studio 3.6.3 with build:gradle:3.6.3.

Answer 1

1) Open the SDK manager by clicking on the icon in the top right of Android Studio. (Or go to File > Settings > Appearance & Behavior > System Settings > Android SDK)

2) Open SDK Tools tab

3) At the bottom-right, click "Show Package Details"

4) Find Android SDK Build-Tools and uncheck the checkbox next to 28.0.3

5) Click apply in the bottom of the window. That will delete the component.

6) Now check the checkbox next to 28.0.3

7) Click apply in the bottom of the window. That will reinstall it.

Answer 2

I tried

e.g. Open Your SDK Path: C:\Users\Administrator\AppData\Local\Android\Sdk\build-tools

• rename android-S -> 31.0.0-rc5
• copy build-tools\30.0.3\dx.bat -> 31.0.0-rc5\dx.bat
• copy build-tools\30.0.3\lib\dx.jar -> 31.0.0-rc5\lib\dx.jar

then the build should succeed.
