4. Screens of my PATH's and folders

How can i sovle this problem?

回答1:

download https://developer.android.com/studio#command-tools and extract in

C:\Users\Zheny\AppData\Local\Android\Sdk folder

and set path like this

C:\Users\Zheny\AppData\Local\Android\Sdk\tools\bin

restart power-shell or command prompt and execute flutter doctor --android-licenses

回答2:

Depending on your install paths, your System Variables should have: ANDROID_HOME C:\Users\\AppData\Local\Android\sdk JAVA_HOME C:\Program Files\Android\Android Studio\jre\

your Path should have: C:\Program Files\Android\Android Studio\jre\bin C:\src\flutter\bin

Then run "flutter doctor" from command prompt (without the quotation marks).

If same error occur, open Android Studio, go to Settings and navigate to "Appearance & Behavior > System Settings > Android SDK", then at the top of the window and to the right of Android SDK Location, click on Edit, and from the window that opens, update your current SDK Manager and install the latest API if not already installed; once everything is updated or installed in this windows, close the Android Studio and close the command prompt.

Open a new command prompt and run "flutter doctor" again (without the quotation marks). Follow the software instructions to accept all Android Licenses.
