Adding external .jar to androidstudio project

Question

I've added the external library bsh-2.0b4.jar to an android project in android-studio by going into Project structure -> Modules -> myProject -> Tab-Dependencies -> + Sign and 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

  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:

  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

  Gradle: error: package bsh does not exist
  Gradle: error: cannot find symbol class Interpreter

Can anyone help me pls?

how do you compile ? using command line or built-in command ? Can you post the dependencies section of build.gradle ? — ben75

Updated the gradle file, and I'm compiling with the build-in command — wasp256

Try this...

Create libs folder under your application folder.
Add .jar files to libs folder.
Then add .jar files to app's build.gradle dependency.
Finally Sync project with Gradle files.

1.Create libs folder:

Change your dependencies like that

dependencies {
   compile 'com.android.support:support-v4:13.0.+'
   compile 'org.beanshell:bsh:2.0b4'
}

You can now remove manually downloaded dependencies in libs directory.

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.

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 aar dependencies better.
