  • 環境:

    win10專業版(創意者),Android studio 2.3.1

  • 問題描述:

    安裝玩Android studio之後建立一個項目,建立AVD之後,運行程式時一直不能啟動AVD,具體描述為:”Waiting for target device to come online”。即“等待目標裝置線上”。

  • 問題分析:

    分析1:此處參考了Android 中 adb 相關問題一文,出現此問題的原因大多是因為adb的連接埠被佔用(eclipse,模擬器等)。

    分析2:也可能有這種問題,博主就是這種問題,參考了 “waiting for target device to come online” in Android Studio 2.3 一文

  • 問題解決:

    分析1:命令列(win+r–cmd)定位到android_sdk/platform-tools/目錄下,執行”adb kill-server”

    分析2:I was also having the same issue 2 days ago when i update my android studio, today I solve my issue when I was playing around with settings then I saw that in my SDK tools setting Android Emulator is uncheck so I simply checked that box and now emulator is working fine. 
    Try this steps may work for you also: 
    Go to SDK tools > SDK Tools 
    Check Android Emulator and click Apply
