java - missing - open android device monitor android studio

Android Device Monitor no se iniciará, ya sea desde Android Studio o desde Terminal-UnsupportedClassVersionError

Question

Recibo el siguiente error al intentar iniciar Android Device Monitor desde la ventana Herramientas en Android Studio en una Mac.

y cuando abro el archivo de registro, encuentro un informe de error muy similar a las otras preguntas de SO similares a esta, especialmente esta . Sin embargo, el uso de sudo no funcionó para mí, aunque obtengo datos de error similares, aunque mucho más cortos:

Macs-MBP:tools macuser$ sudo ./monitor

./monitor: line 41: exec: /Users/macuser/Library/Android/sdk/tools/lib/monitor-/monitor.app/Contents/MacOS/monitor: cannot execute: No such file or directory

Trasfondo: Después de realizar una nueva y completa instalación de Android Studio en esta computadora portátil (El Capitan) intenté iniciar el monitor desde el interior del IDE. Se quejaba de que ejecutarlo requería Java 1.6. Así que instalé Java 6. Luego, cuando lo probé, recibí el mensaje de error anterior.

Obtuve lo siguiente cuando salí de Terminal java_home -V

Answer 1

La respuesta anterior no funcionó para mí. Estoy usando JAVA8, tanto el Android JAVA_HOME como /usr/bin/java . Lo que es más extraño para mí es que a mi directorio / herramientas también le falta la herramienta uiautomationviewer . Entonces me hizo preguntarme si algo salió mal durante la instalación.

Lo que terminé haciendo fue descargar una versión anterior de SDK-tools (seguí las instrucciones aquí ) y reemplacé toda la carpeta sdk / tools. Y funcionó....

Answer 2

Estoy teniendo el mismo problema. En función del archivo de registro, la nueva versión de Android Studio requiere Java 8 "Mayoridad no admitida.minor versión 52.0": Mayor.minor versión no compatible 52.0

Estoy ejecutando Linux, actualmente tengo instalado java8, así que solo necesitaba usar:

update-alternatives --config java

y

update-alternatives --config javac

entonces todo funcionó.

Parece que está usando una Mac, por lo que puede o no necesitar hacer lo siguiente después de instalar Java 8: Java 7 instalado en Mac OS X pero la Terminal todavía está usando la versión 6

Información de Unsupported major.minor versión 52.0 fuente: 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

Answer 3

Confusamente, no tenía Java 8 instalado en una ubicación compartida (solo la versión incluida en Android Studio). Instalarlo a través de homebrew resolvió mi problema.

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)

Answer 4

Android Studio viene con Java 1.8 incorporado, por lo que no fue un problema cuando estás desarrollando una aplicación de Android. Pero cuando inicia Android Device Monitor, usa un compilador Java externo que se ejecuta en su sistema operativo. Si preinstaló Java antes, no será un problema. De lo contrario, enfrentarás el mismo problema.

Intenté establecer la ruta JAVA_HOME en java empaquetado en Android Studio. No funciona, probablemente porque es la versión de openjdk.

Mi solución fue descargar Java JDK 1.8 de Oracle e instalarlo en mi computadora.
