Android 工具链 - 为 Android 设备开发（Android SDK 版本 29.0.2）

Question

运行“ flutter doctor --android-licenses ”命令时出现以下错误

A newer version of the Android SDK is required. To update, run:
/Users/taleb/Library/Android/sdk/tools/bin/sdkmanager --update

注意：

 * my android SDK is updated
 * I added all of the paths to 'bash_profile' (mac)

这是我的“ bash_profile ”

export PATH="$PATH:/⁨Users⁩/taleb⁩/Library/Android⁩/sdk⁩/platform-tools"
export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools⁩
export PATH=$PATH:$ANDROID_HOME/platform-tools⁩
export PATH="$PATH:/Users/taleb/Developer/flutter/bin"

我还运行了“ sdkmanager --update ”命令，但出现以下错误：

打开android studio，tools >> SDK manager >> SDK Platforms，然后下载API Level为（29）的平台，然后点击Apply。 在那之后跑flutter doctor
