and when run:
flutter doctor --android-licenses
get me this result:
A newer version of the Android SDK is required. To update, run:
c:\Android\android-sdk\tools\bin\sdkmanager --update
and when update sdkmanager show this error to me:
Exception in thread "main" java.lang.NoSuchFieldError: FN_AAPT2
at com.android.sdklib.BuildToolInfo.<init>(BuildToolInfo.java:362)
How can i solve this challenge?
I solved this problem by installing the command line tool.
And then rerun
flutter doctor --android-licenses
There is an SDK Manager Icon in the top right of Android Studio between the AVD manager icon and the magnifying glass. Click it.
You get a modal that shows you are in System Settings -> Android SDK n the left menu. In the middle area there is an SDK Tools tab so click it.
Check off the box that says "Android SDK Command-line Tools (latest)" and click Apply. It will install it (about 105M). Now run flutter doctor --android-licenses
and say yes to everything. The error should be gone.
