安卓真機USB連接測試流程
我用的是安卓真機USB測試，先說一下操作流程：
- 點擊手機設置
- 點擊關於本機
- 在‘版本號’上快速點擊多次，直到提示已經打開開發者模式
- 然後返回上一級設置
- 點擊其他設置
- 點擊開發者選項
- 將USB調試選項打開
- 在手機上彈出的是否允許USB調試選項中允許
設備授權失敗
用adb devices查看設備列表, 顯示unauthorized未授權。
bdealsdeMacBook-Pro:~ bdeals$ adb devices
List of devices attached
Q8OFQKZ5VW6D85QG unauthorized
用adb shell時顯示device unauthorized
bdealsdeMacBook-Pro:~ bdeals$ adb shell
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
重啓服務也未能解決這個問題
bdealsdeMacBook-Pro:~ bdeals$ adb kill-server
bdealsdeMacBook-Pro:~ bdeals$ adb start-server
* daemon not running; starting now at tcp:5037
* daemon started successfully
到.android目錄下刪除pubkey.pub也未解決問題
最後，刪除.android整個文件夾，並重啓服務後成功解決。
bdealsdeMacBook-Pro:~ bdeals$ rm -rf .android
bdealsdeMacBook-Pro:~ bdeals$ adb devices
List of devices attached

Android Studio添加模擬器失敗
問題描述：添加模擬器時彈出窗口顯示An error occurred while creating the AVD. See idea.log for details，不論添加何版本的都是如此
解決方法：將舊的android studio刪除，重裝Android Studio後可順利添加模擬器
徹底刪除掉android studio可用以下命令
在終端輸入
rm -Rf /Applications/Android\ Studio.app
rm -Rf ~/Library/Preferences/AndroidStudio*
rm ~/Library/Preferences/com.google.android.studio.plist
rm -Rf ~/Library/Application\ Support/AndroidStudio*
rm -Rf ~/Library/Logs/AndroidStudio*
rm -Rf ~/Library/Caches/AndroidStudio*
第二步：刪除所有Projects
rm -Rf ~/AndroidStudioProjects
第三步：刪除gradle相關文件
rm -Rf ~/.gradle
第四步：卸載所有Android Virtual Devices(AVDs) and *.keystore. note:
rm -Rf ~/.android
第五步：刪除Android SDK tools，對應自己的sdk目錄即可
rm -Rf ~/Library/Android*
