> Do you have any better approach to JNI calls other than Djinni, SafeJNI, SWIG, RPC-like with bulk of work on Java side? I use this homegrown solution on an Android app of mine which integrates with the CPython interpreter: https://github.com/joaoventura/pybridge/ https://github.com/joaoventura/pybridge/ It is RPC-like, but the code is quite simple: https://github.com/joaoventura/pybridge/#how-it-works https://github.com/joaoventura/pybridge/#how-it-works. In the java-side, you just create a JSON object, send it to Python-land and get the result. Here's the java example in the code (https://goo.gl/sw4JLt https://goo.gl/sw4JLt) and here's the python function that it calls (https://goo.gl/hgbqVR https://goo.gl/hgbqVR). Don't know if it's what you're looking for, or how it compares to the solutions you mentioned above, but I had someone from dropbox contributing a fix, and mentioning that going forward with a solution like this he would need something similar to djinni regarding error handling: https://github.com/joaoventura/pybridge/pull/3#issuecomment-281893234 https://github.com/joaoventura/pybridge/pull/3#issuecomment-...
