Android Device Monitor ne sera pas lancé, que ce soit à partir de Android Studio ou à partir de Terminal-UnsupportedClassVersionError

Question

Android Device Monitor ne sera pas lancé, que ce soit à partir de Android Studio ou à partir de Terminal-UnsupportedClassVersionError

je reçois l'erreur suivante en essayant de lancer Android Device Monitor depuis la fenêtre Outils dans Android Studio sur un Mac.

et quand j'ouvre le fichier journal je trouve un rapport d'erreur très similaire à l'autre donc des questions similaires à ceci, esp celui-ci . Cependant, l'utilisation sudo n'a pas fonctionné pour moi, bien que j'obtienne des données d'erreur similaires, bien que beaucoup plus courtes:

Macs-MBP:tools macuser$ sudo ./monitor

Backstory: après avoir fait une installation complète et Nouvelle Android Studio sur cet ordinateur portable (El Capitan), j'ai tenté de lancer le moniteur à partir de l'IDE. Il s'est plaint que son exécution nécessitait Java 1.6. J'ai donc installé la version 6 de Java. Puis quand je l'ai essayé j'ai eu le message d'erreur ci-dessus.

j'obtiens ce qui suit quand j'ai couru du Terminal java_home-V

j'ai le même problème. Basé sur le fichier log, la nouvelle version D'Android Studio nécessite Java 8 "major non pris en charge.version mineure 52.0": non pris en charge majeure.version mineure 52.0

j'exécute Linux, j'ai actuellement java8 installé donc j'ai juste besoin d'utiliser:

update-alternatives --config java

et

update-alternatives --config javac

alors tout a fonctionné.

on dirait que vous utilisez un Mac, donc vous pouvez ou ne pas avoir besoin de faire ce qui suit après l'installation de Java 8: installé Java 7 sur Mac OS X mais le Terminal utilise toujours la version 6

Info de major non supporté.minor version 52.0 source: wikipedia

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

ce qui est déconcertant, c'est que je n'avais pas installé Java 8 dans un emplacement partagé (seulement la version fournie dans Android Studio). L'installer par homebrew a résolu mon problème.

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 est livré avec Java 1.8 intégré, donc ce n'était pas un problème lorsque vous développez android app. Mais lorsque vous lancez Android Device Monitor, il utilise un compilateur java externe qui s'exécute sur votre système D'exploitation. Si vous avez préinstallé Java avant, il ne sera pas un problème. Sinon, vous êtes confrontés au même problème.

j'ai essayé de mettre JAVA_HOME path à java emballé dans Android Studio. Il ne fonctionne pas, probablement parce qu'il est openjdk version.

My la solution était de télécharger Java JDK 1.8 à partir D'Oracle et d'installer dans mon ordinateur.

Si vous ouvrez le message d'erreur particulier, vous verrez les premières ligne du message d'erreur comme ci-dessous.

!SESSION 2017-12-20 08:17:02.597 -----------------------------------------------
eclipse.buildId=unknown
java.version=9.0.1
java.vendor=Oracle Corporation

voilà ce que j'ai. J'ai installé java 8 et 9 sur mon mac et j'ai fait de java 8 la valeur par défaut. Selon le message d'erreur java virtual device a pris java 9 mais son besoin 8. C'est là que le probelm est arrivé.Donc j'ai désinstallé le java 9 de ma machine puis il a commencé à fonctionner très bien.

la réponse ci-dessus ne marchait pas pour moi. J'utilise JAVA8, à la fois L'Android JAVA_HOME et /usr/bin/java . Ce qui est encore plus bizarre pour moi, c'est que l'outil uiautomationviewer est également absent de mon répertoire/ outils. Je me suis donc demandé si quelque chose s'était mal passé pendant l'installation.

ce que j'ai fini par faire était de télécharger un verion plus ancien de SDK-tools (J'ai suivi les instructions ici ), et j'ai remplacé tout le dossier sdk/tools. Et cela a fonctionné....

le même problème a été observé le: macOS Sierra 10.12.6 Android Studio 3.0.1

a été résolu par: désinstaller Java SE Development Kit 8u 152 Et installation Java SE Development Kit 8u151 de: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

essayez de faire un clic droit sur sdk/tools / monitor.bat et cliquez sur" Exécuter en tant qu'administrateur "
