MacのAndroid Studioの[ツール]ウィンドウからAndroidデバイスモニターを起動しようとすると、次のエラーが表示されます。

ログファイルを開くと、これに似た他のSO質問と非常によく似たエラーレポートが見つかります。esp this one 。ただし、Sudoを使用しても機能しませんでしたが、はるかに短いものの、同様のエラーデータが表示されます。

バックストーリー：このラップトップ（El Capitan）に完全なAndroid Studioのインストールを完了した後、IDE内からモニターを起動しようとしました。それを実行するにはJava 1.6が必要であると不平を言いました。そこで、Java 6をインストールしました。それを試してみると、上記のエラーメッセージが表示されました。

Terminal Java_home -Vから実行すると、次のようになります

私は同じ問題を抱えています。ログファイルに基づいて、Android Studioに必要なJava 8 "サポートされていないmajor.minorバージョン52.0"： nsupported major.minorバージョン52.

Linuxを実行していますが、現在Java8がインストールされているため、使用する必要がありました。

update-alternatives --config Java

そして

update-alternatives --config javac

その後、すべてが機能しました。

Macを使用しているかのように見えるため、Java 8をインストールした後に次の操作を行う必要がある場合とそうでない場合があります。 Installed Java = Mac OS Xでは7ですが、ターミナルはまだバージョン6を使用しています

サポートされていないmajor.minorバージョン52. ソース： wikipedia からの情報

  • J2SE 8 =52
  • J2SE 7 = 51
  • J2SE 6.0 = 50
  • J2SE 5.0 = 49
  • JDK 1.4 = 48
  • JDK 1.3 = 47
  • JDK 1.2 = 46
  • JDK 1.1 = 45

紛らわしいことに、共有場所にJava 8をインストールしていません（Android Studio）にバンドルされているバージョンのみ。homebrewを使用してインストールすると問題が解決しました。

brew cask install Java

$ Java -version
Java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

Android Studioには、Java 1.8が組み込まれています。したがって、開発中の問題はありませんでしたAndroidアプリ。ただし、起動時Android Device Monitorは、OSで実行される外部Javaコンパイラを使用します。以前にJavaをプレインストールしている場合、そうでなければ、あなたは同じ問題に直面するでしょう。

Java_HOMEパスをJava Packed in Android Studioに設定しようとしました。おそらくopenjdkバージョンであるため、動作しません。

私の解決策は、OracleからJava JDK 1.8をダウンロードして、コンピューターにインストールすることでした。

上記の答えは私にはうまくいきませんでした。私はJava8を使用しています。両方ともAndroid Java_HOMEおよび/usr/bin/Java。私にとって奇妙なのは、私のtools /ディレクトリにもuiautomationviewerツールが欠けていることです。だから、インストール中に何かがうまくいかなかったのだろうかと思いました。

私がやったことは、古いバージョンのSDK-toolsをダウンロードすることでした（指示に従って here ）、sdk/toolsフォルダ全体を置き換えました。そしてそれは働いた....

同じ問題がありました。 Win10 + JDK 12 + Android Sdk。「monitor.bat」を実行したとき、それはまったく同じ問題です。モニターアプリケーションは最新のJavaバージョンの命名規則JRE 8をインストールすると（次のように）、問題はなくなりました。

c:\>Java -version Java version "1.8.0_221" Java(TM) SE Runtime Environment (build 1.8.0_221-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)
