jar file under res/raw folder

I need to place a 3rd party jar file as a raw resource under res/raw in my apk. But with Android Studio (Im using 1.3.1), it seems the file disappears from the final apk. Presumably because of the extension of 'jar'.

I cannot rename it and do not want it to be included into dex classes. My app needs to access to the jar runtime as a raw resource.

Any advice (maybe modification to gradle tasks can do) of how this is achieved?

According to official Android documentation you should always put your .jar files under the /libs folder only.

See the official documentation,

raw/

For arbitrary raw asset files. Saving asset files here is essentially the same as saving them in the assets/ directory. The only difference is how you access them. These files are processed by aapt and must be referenced from the application using a resource identifier in the R class. For example, this is a good place for media, such as MP3 or Ogg files.

libs/

Contains private libraries. Stored in the main application module.

Once you have placed a .jar file inside the /libs folder, you can easily reference it via gradle.build file,

For example I've places this acra-4.6.2.jar file inside the /libs folder

enter image description here

and made a reference in gradle.build file like this,

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile files('libs/acra-4.6.2.jar')
}
