问题
Installed Android 4.1 on Ubuntu 20.04. Getting the following error:
Gradle sync failed: com.android.tools.idea.gradle.project.sync.idea.issues.SdkPlatformNotFoundException: Module: 'app' platform 'android-29' not found.
On opening the SDK manager I get the following screen:
I also executed
$ANDROID_HOME/cmdline-tools/tools/bin/sdkmanager --licenses
How to fix this?
------ edit ---------
This is what shows in the SDK Platforms tab. Unchecking the "Hide Obsolete Packages" doesn't change anything.
回答1:
As the error is saying. Install the SDK Platform with API Level 29. YOu need to switch to the tab " SDK Platforms and install the right API Level:
-----------edit--------------
maybe you changed accidently your SDK location.
Mine is on C:\Users\elmo\AppData\Local\Android\Sdk
Pay attention: using it on windows.
回答2:
go to the "sdk platforms" you can find it by click on navigate->find anywhere than enter "sdk" than what you need is to find the api level you need (29 in your case) and check the box near it.
