Android中的OpenTok + Twilio SDK冲突

Question

I am developing a phonegap app for Android and iOS. I am also using Twilio and OpenTok SDK. After struggling some time I could make it both SDK to work in IOS. There was a problem with openssl libraries, because both sdk use it.

However, when testing on Android, I have linker problems. Linker is not able to find opentok.so, in presence of twilio-native.so. After removing twilio references, it all works correctly.

I have tested it on Android 4.3 and Android 5.0.

As you can see in the logs, loader is unable to find library. After removing twilio references, there is no problem.

 ── src

                    └── statusbar
                    └── StatusBar.java

So here is a part of the android platform folder.

├──  libs
│   ├── Pushwoosh.jar
│   ├── android-support-v4.jar
│   ├── armeabi
│   │   ├── libopentok.so
│   │   └── libtwilio-native.so
│   ├── armeabi-v7a
│   │   └── libtwilio-native.so
│   ├── mips
│   │   └── libtwilio-native.so
│   ├── opentok-android-sdk-2.3.1.jar
│   ├── twilioclient-android.jar
│   └── x86
│       ├── libopentok.so
│       └── libtwilio-native.so

Here you can see the libs folder. As I said before, when I remove twilio libs, OpenTok works perfect.

The problem I was having with iOS is that both sdk use libssl, and they are different version. The solution was delete twilio openssl library. (Even in that case, I think the only problem was that twilio brokes, not openTok, so it is weird though).

Answer 1

I have come up with the solution. Twilio cordova plugin for android is incompatible with newer version of twilio sdk. So you have to use twilio sdk version 1.2.2 . Also, in order to make both plugin work together, you have to use opentok sdk version 2.5.0.
