I'd tried to used flutter to development, but when I used android emulator I got this error.

Execution failed for task ':firebase_core:compileDebugJavaWithJavac'. Could not find tools.jar

I tried add

android.useAndroidX=true android.enableJetifier=true

or

org.gradle.java.home=/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

in gradle.properties, but it was same issues.

And when I command flutter doctor, I got this information.

Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 2.8.1, on macOS 12.0.1 21A559 darwin-x64, locale en-AU)
[✓] Android toolchain - develop for Android devices (Android SDK version 32.1.0-rc1)
[✓] Xcode - develop for iOS and macOS (Xcode 13.2.1)

    ! Error: S  iPhone is busy: Fetching debug symbols for S  iPhone. Xcode will
      continue when S  iPhone is finished. (code -10)

! Doctor found issues in 1 category.

How can fix it?

Go to C:/users//.gradle/cache delete everything then run again. I hope this helps.
