Adding external .jar to androidstudio project
提问by wasp256
I've added the external library bsh-2.0b4.jarto an android project in android-studio by going into Project structure -> Modules -> myProject -> Tab-Dependencies -> + Signand then add the .jar file.
I also tried to copy the file into the /libs directory and then rightclick in studio and add as library...(both methods independently!!). I inserted the following code as a test
我已经bsh-2.0b4.jar通过进入Project structure -> Modules -> myProject -> Tab-Dependencies -> + Sign然后添加 .jar 文件将外部库添加到 android-studio 中的 android 项目。我还尝试将文件复制到 /libs 目录中，然后在 studio 和add as library...（两种方法独立！！）中右键单击。我插入了以下代码作为测试
import bsh.Interpreter;
...
Interpreter interpreter = new Interpreter();
interpreter.eval("result = (7+21*6)/(32-27)");
return interpreter.get("result").toString();
I compile with the buildin button in android. The build.gradle looks like:
我用android中的buildin按钮编译。build.gradle 看起来像：
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.5.+'
}
}
apply plugin: 'android'
repositories {
mavenCentral()
}
android {
compileSdkVersion 17
buildToolsVersion "17.0.0"
defaultConfig {
minSdkVersion 9
targetSdkVersion 17
}
}
dependencies {
compile 'com.android.support:support-v4:13.0.+'
}
But when I compile everything I receive the error
但是当我编译所有内容时，我收到错误
Gradle: error: package bsh does not exist
Gradle: error: cannot find symbol class Interpreter
Can anyone help me pls?
有人可以帮我吗？

Change your dependencies like that
像这样更改您的依赖项
dependencies {
compile 'com.android.support:support-v4:13.0.+'
compile 'org.beanshell:bsh:2.0b4'
}
You can now remove manually downloaded dependencies in libsdirectory.
您现在可以删除libs目录中手动下载的依赖项。
What you did was adding libraries to Android Studio project only. You should always add them to Gradle build files as only this is interpreted by Android Build Tools.
您所做的只是将库添加到 Android Studio 项目中。您应该始终将它们添加到 Gradle 构建文件中，因为 Android 构建工具仅对此进行解释。
There is also new version of build tools 18.0.1, you can install them and change version in you build.gradle. As far as I know they can handle aardependencies better.
还有新版本的构建工具 18.0.1，您可以安装它们并在您的build.gradle. 据我所知，他们可以aar更好地处理依赖关系。
