[flutter_tools] Can't build apps targeting Android 13 Tiramisu (API level 33) #104170
Description
Overview
Android 13 Tiramisu (API 33) has recently entered beta and soon (in June) will enter "platform stability" phase (source).
As a developer, I'd like to test whether my application works with API 33 (e.g to test new notification permission).
To do this, I first bumped targetSdkVersion and compileSdkVersion to 33 in my <flutter_project_root>/android/app/build.gradle. It failed with the following error:
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':app:mergeDevDebugAssets'.
> Could not resolve all dependencies for configuration ':app:devDebugRuntimeClasspath'.
> Could not create task ':app:minifyDevReleaseWithR8'.
> Failed to find Platform SDK with path: platforms;android-33
Then I read this short tutorial and learned that I have to set targetSdkVersion and compileSdkVersion to "Tiramisu" (I am using AGP 7.0.4 – in <flutter_project_root>/android/build.gradle I have dependencies { classpath 'com.android.tools.build:gradle:7.0.4' /.../ }`. After doing so, I got the following error:
FAILURE: Build failed with an exception.
* Where:
Script '/Users/bartek/fvm/versions/stable/packages/flutter_tools/gradle/flutter.gradle' line: 461
* What went wrong:
A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
> For input string: ""
This caught my attention. I opened /Users/bartek/fvm/versions/stable/packages/flutter_tools/gradle/flutter.gradle, went to line 461 and saw this code.
For reference, here's the PR that introduced the
substring(8) as intonproject.android.compileSdkVersion
It assumes that compileSdkVersion is an int, which is not the case for Tiramisu.
Quick fix
I wanted to make the app target API 33 and compile, so I modified the /Users/bartek/fvm/versions/stable/packages/flutter_tools/gradle/flutter.gradle. Actually, I've submitted a PR for this so it's easier to see changes.
After the above modifications, the Gradle build was still failing with:
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':app:mergeDevDebugAssets'.
> Could not resolve all dependencies for configuration ':app:devDebugRuntimeClasspath'.
> Could not create task ':app:minifyDevReleaseWithR8'.
> Failed to find target with hash string 'Tiramisu' in: /Users/bartek/androidsdk
After changing compileSdkVersion from "Tiramisu" to "android-Tiramisu" and targetSdkVersion to 33, the build succeeded and my app ran 🚀. This SO thread helped me.
Steps to Reproduce
- Create a new flutter project (e.g the default counter app).
- Set
targetSdkVersionandcompileSdkVersionto"Tiramisu"influtter_project_root/android/app/build.gradle - Execute
flutter run - Watch it fail
Expected results:
I expected my app to build successfully and run on the physical/virtual android device.
Actual results:
Gradle build failed with the following exception:
FAILURE: Build failed with an exception.
* Where:
Script '/Users/bartek/fvm/versions/stable/packages/flutter_tools/gradle/flutter.gradle' line: 461
* What went wrong:
A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
> For input string: ""
Code sample
I hope that I provided everything that might be needed for reproduction. If anything is missing, please let me know 🙏

As a sidenote, below you can see that flutter doctor can't handle android-Tiramisu as well.
