安卓+斯卡拉+ preinstalled的Scala库+禁用的ProGuard抛出了ClassNotFoundException [英] android + scala + preinstalled scala libraries + disabled proguard throws ClassNotFoundException
问题描述
这一壮举的最终目的：使用Android设备通过快速开发的编译，而不需要使用ProGuard的每一个单一的时间（这将导致巨大的延迟）
Final purpose of this feat: Use android device for development by fast compiling without needing to use proguard each single time (which causes huge delays)
第一次尝试上的索尼爱立信Xperia迷你临
我已经安装在它的的CyanogenMod 这已经是的扎根并根检查应用已经证实它。
I have installed in it Cyanogenmod which is already rooted and the root checker app has verified it.
这是我以前的嵌入Scala库 2.9.1里面的Android设备应用程序：
https://github.com/jbrechtel/Android-Scala-Installer
该行使用库机器人：名字=斯卡拉_... 现在包含在AndroidManifest
This is the app I used to embed Scala library 2.9.1 inside android device:
https://github.com/jbrechtel/Android-Scala-Installer
The lines uses-library android:name="scala_... are now included inside the AndroidManifest
在上面的动作我做的项目/ Build.scala里面的一些细微的变化这样的行： useProguard在安卓=假，
After the above actions I did some minor changes inside "project/Build.scala" like this line: useProguard in Android := false,
我可能失去了一些东西，因为重新编译和执行的android后：启动设备我的抛出java.lang.ClassNotFoundException
这是你期望得到，当你还没有做previous步骤（生根设备安装和内部设备的Scala库）的误差
I am probably missing something because after recompiling and executing android:start-device I got java.lang.ClassNotFoundException
which is the error you are expecting to get when you have not done the previous steps (rooting device and installing scala libraries inside device)
任何意见，欢迎！谢谢
PS：的IntelliJ是当前项目所选择的IDE使Eclipse和相对插件是不是一种选择
推荐答案
有什么错什么我所提到的！
There is nothing wrong with what I have mentioned above!
但Android的斯卡拉安装程序内的命令，该命令要求被安装为可写了/系统文件夹中。不幸的是这不我姜饼的Android手机上运行，这可能是一般情况。
BUT there is a command inside Android Scala Installer which requests the "/system" folder to be mounted as writable. Unfortunately this does not work on my gingerbread android phone and this might be the general case.
我只是注释掉挂载/系统为可写的操作（也命令mount /系统为只读），并成功安装库！
请注意，我手动设置/系统
I simply commented out the operation of the mount /system as writable (and also the command mount /system as read only) and the libraries installed successfully!
Note that I set manually the permissions of /system as writable before installing libraries
其实我叉GitHub的信息库，因此，你可以找我执行在这里：
https://github.com/pligor/scala-android-libs
In fact I forked the github repository and therefore you can find me implementation over here: https://github.com/pligor/scala-android-libs
要总结。是在你的Scala Android源$ C $ C所需要的唯一改变是Build.scala文件来设置设置ProGuard的是假的，你包括使用＆LT;使用库机器人：名字=斯卡拉_... Android清单中。
To summarize. Yes the only alterations needed in your scala android source code is to set the settings in Build.scala file for proguard to be false and you include the uses <uses-library android:name="scala_... inside Android Manifest.
