Dynamically linking plugin in GStreamer on Android

[Bruce Tsai]

Hi Sebastian,

Thanks for your quick reply.
But I got message of no suitable plugins found.

Here is my building procedures:
1. Develop a new plugin, based on gst-template/gst-plugin
2. In order to build appropriate shared libraries on Android, I enter shell
environment by "cerbero -c config/cross-android.cbc shell"
3. Then I go to gst-template/gst-plugin and build my plugin
4. Copy so file into folder "assets/test" in my app
5. Set environment path by setenv("GST_PLUGIN_PATH", "assets/test", 1);
6. Use ndk-build to build the app
7. Run app but get error messages

Hope I did not miss something.
