rhino-android's Issues

Reuse compiled dexes

Hello F43nd1r, this is more like a question rather than an issue, but here it goes. I have implemented a similar solution like yours in my Rhino implementation. If i'm not wrong, Rhino emits java bytecode again every time it runs an script, even if it ran it previously, then your library dexes it, then it is loaded with android's dex classloaders.

Would it be possible to store those compiled dexes, and run them directly the next time the same script is run?

I'm looking to squeeze performance by persisting those compiled scripts, so even if the app dies and restarts, it doesn't need to compile them again. Do you think this is feasible?

Hello! first, thx your project!

I'm making a game and using JS to create game UI, when I enter (RhinoAndroidHelper.enter()) the context and create the first JavaAdapter, it works, but when I exit() the context and sometimes re-enter context and create another JavaAdapter, it's throw an Exception like above.

And this script on desktop-java is works.

PS: I created first JavaAdapter and it extend A.class, and second JavaAdapter extend B.class, when I creating second JavaAdapter(B.class), it's seem like still create an Adapter extend A.class, just like somethings not clear after first create. (im sorry for my bad English...)

Rhino closes automatically

xml node attribute name is always “*”

The following javascript code works well and get "id" as expected on JVM. But when I run it on android with this library, I always get "*". Is it caused by the diffs between JVM and android? How can I get the expected result ? Or any other ways to get the attribute name of xml node?

(<xml id="foo"></xml>).attributes()[0].name()

Missing dependencies for org.mozilla.javascript.* in 1.5

Hello, I've been trying to update rhino to 1.5, but seems that it doesn't include org.mozilla.javascript.* classes. On 1.4 it's all fine. Should we add this dependency separatelly to our project?
