Android SDK "Android API 29 Platform" is not found on the disk or corrupted

[EvgeniiaVak]

Steps to Reproduce

1. create a new flutter project in android studio (I selected for android, ios and web)
2. when opening main.dart observe this notification (appears by itself, when the project is just created)
   
3. try to configure in Project Settings -> Project and -> Modules any sdk
4. observe that android emulator vanishes from the top-right Flutter Device selection dropdown

To fix this I explicitly set up <no SDK> and the emulator appeared again in the dropdown, but the android sdk warning stays.

Also getting this error for the first time, but in my case it is API 32. Similarly cannot access emulators, or even physical devices, only the Linux target (my dev OS).

[philipmjohnson]

Also getting this error. Just started happening two days ago. MacOS Ventura 13.2.

[petergloor]

Same Issue with API 29 on Linux.

[WrathOP]

I am getting this error too on macos sonoma

[Decron]

Same here. Macbook Pro 2022 / Ventura, just upgraded to Apple Sillicon from 2014 MPB. Also getting all-clear from flutter doctor

Edit: I was just able to make the banners disappear for 29 and 30 by uninstalling and reinstalling the following from Preferences/Languages & Frameworks/Android SDK. Errors disappeared after restarting Android Studio

• Android 12.0 (API 31)
• Android 11.0 (API 30)
• Android 10.0 (API 29)
• Android 9.0 (API 28)

Seems you need to install the APIs directly above and below the errant APIs for some reason.

Also fiddled with SDK in Platform Settings for awhile, not sure if that helped anything

[holocronweaver]

+1 to @Decron, simply uninstalling and reinstalling the Android SDK seems to resolve the issue.

However this is just a workaround - the SDK shouldn't have been marked as corrupted in the first place, so there is still a bug to fix in Android Studio.

[nguyengiabao0805]

I did it

[abd-koumare]

Thanks @nguyengiabao0805 it works !
File -> Project Structure -> SDKs then make sure SDK home path is correct and Android API Level match with Build target.

[Apollo108]

didn't help, I reinstalled SDK from the SDK manager, also didn't help. M2 Pro, MacOS Sonoma. Any other ideas?

[abd-koumare]

@Apollo108 follow this step File -> Project Structure -> SDKs then make sure SDK home path is correct and Android API Level match with Build target.

If it didn't works take a screenshot of File -> Project Structure -> SDKs

Hello @abd-koumare

This is my screenshot. You can see the error message too. I have uninstalled and reinstalled API 29 already.
Android Studio Giraffe | 2022.3.1 Patch 2 Build #AI-223.8836.35.2231.10811636, built on September 15, 2023

[abd-koumare]

@omidshojaee Ensure that the Build target dropdown does not have Android API 29 Platform. If this API version is not available, you can obtain it by navigating to the SDK Manager (File -> Tools -> SDK Manager -> SDK Platform) and then update the build target to Android API 29 Platform accordingly.

Hi, @abd-koumare
I have the error. How can I add an new path ? I have already a path to Androif API 34

[abd-koumare]

You have selected the openjdk path instead of the Android SDK home path. Please verify that the correct path is either C:\Program Files\Android\sdk or C:\Users\Yourname\AppData\Local\Android\Sdk, and then ensure that you set the Android SDK home path. Additionally, adjust the Build target accordingly.
