Android Studio 3.0 rc2：Android設備監視器未能打開

我最近使用應用程序內更新部分的Beta通道將我的Android Studio更新爲3.0 rc2。Android Studio 3.0 rc2：Android設備監視器未能打開

今天我想使用Android設備監視器發生異常，並保存到sdk文件夾內部。

日誌是這樣的：

我不知道如何處理這個錯誤，我需要周圍的一種方式。如果沒有提及「下載穩定版本」和降級，我會很高興解決它的任何建議。

UPDATE：後，我試圖通過更新部分的穩定頻道更新到穩定版，我得到的錯誤，有些文件丟失

gradle/m2repository/com/android/java/ 
gradle/m2repository/com/android/java/tools/ 
gradle/m2repository/com/android/java/tools/build/ 
gradle/m2repository/com/android/java/tools/build/java-lib-model-builder/ 
gradle/m2repository/com/android/java/tools/build/java-lib-model/

我想也許我可以更新每一個模塊解決這個問題

更新2：取消以前的錯誤，並運行Android Studio之後，這似乎是更新，但故障仍然存在，這裏是錯誤更新到穩定版後：

UPDATE-3：搜索了很多之後，我發現了一個解決方案，但讓我加入本更新程序可以質疑這不是問題的答案。

我可以通過去/sdk/tools/手動運行Android設備監視器，並通過cmd或powershell運行monitor.bat文件，現在我可以訪問此功能，但即使現在，Android Studio也無法打開它！！如果有人可以幫我發表一個答案，告訴我一個解決這個問題的辦法。

的Android 3.0演播室穩定幾天前發佈，嘗試更新並檢查問題是否仍然存在 –

@OmarAlHalabi您是指從更新部分的Stable頻道?!我昨天檢查，我會更新的問題，如果我可以更新到穩定版 – MrSinaRJ

@OmarAlHalabi由於一些衝突，我無法更新到穩定版本，我更新了有關這個問題的問題！ – MrSinaRJ

了很多嘗試和追趕的後！我終於解決了這個問題。 Android Studio 3.0尚未完全支持JDK 9 在我的系統上安裝JDK 8並將其設置爲JAVA_HOME變量並重新啓動系統後，所有工作都已開始。我得到了它，因爲我想安裝Nativescript，我不能導致它僅支持JDK 8那是我的第一個線索

設置JAVA_HOME變量設置爲JDK 8目錄，一切都會好起來

如果您使用的是Windows嘗試以管理模式打開你的Android工作室（以管理員身份運行）
