为Android开发环境设置处理

Question

我正在尝试为Android处理设置开发环境。

我按照SDK安装和处理的所有说明进行操作，但是仍然无法编译内置示例。

在Linux中，我得到：

注意两件事：JAVA_HOME在我的Linux机器上设置为jdk目录。 但是处理说JAVA_HOME设置为：/home/poko/Downloads/software/processing-2.1/java，这是自己处理的Java发行版。 第二件事是在处理自己的Java分发中不存在keytool命令。

提前致谢。

我只是有同样的问题。

解决方法是手动执行keytool命令。 因为它的需要只做一次。 请注意，输出告诉您以下信息：

, or manually execute the following command:
/home/poko/Downloads/software/processing-2.1/java/bin/keytool -genkey -alias AndroidDebugKey -keyalg RSA -dname "CN=Android Debug,O=Android,C=US" -validity 10950 -keypass android -keystore /home/poko/.android/debug.keystore -storepass android

您只需将路径从以下位置更改为正确的java路径：

/home/poko/Downloads/software/processing-2.1/java

到（如果在系统中正确设置了JAVA_HOME，则使用它）

$JAVA_HOME/bin/keytool -genkey -alias AndroidDebugKey -keyalg RSA -dname "CN=Android Debug,O=Android,C=US" -validity 10950 -keypass android -keystore /home/poko/.android/debug.keystore -storepass android

或仅将$ JAVA_HOME替换为正确的Java路径。 在我的情况下是/ usr / lib / jvm / default-java，我使用的是基于Ubuntu 12.04.3 LTS的KXStudio。

不知道如何以更清洁的方式将ATM修复。 让我知道是否可以解决。
