I tried most of the things but nothing worked for me. After spending some time i got the solution
Open {Android SDK dir}\build-tools and also open project.properties in our project
Check for sdk.buildtools=29.0.0 (If you don't have this, just add it manually)
Change 29.0.0 entry based on {Android SDK dir}\build-tools folder and start the build
Ex:
- {Android SDK dir}\build-tools i have 28.0.3. Then I've changed sdk.buildtools=28.0.3 gave the build. Not worked
- {Android SDK dir}\build-tools i have 25.0.3. Then I've changed sdk.buildtools=25.0.3 gave the build. Not worked
- {Android SDK dir}\build-tools i have 24.0.3. Then I've changed sdk.buildtools=24.0.3 gave the build. Success
