Hi. If you are using the source code from Github, then while compiling the Android example, libRealSenseIDSwigJNI.so should be built automatically. If you are using the SDK, then you have it prebuilt in release (for both secured and unsecured flavors). Can you describe the exact steps you took to build and install it to the device?
