An reference exampe can be found at [chainer-nnvm-example](https://github.com/tkat0/chainer-nnvm-example) Above example will directly run the compiled model on RPC target. Below modification at [rum_mobile.py](https://github.com/tkat0/chainer-nnvm-example/blob/5b97fd4d41aa4dde4b0aceb0be311054fb5de451/run_mobile.py#L64) will save the compilation output which is required on android target. ``` lib.export_library("deploy_lib.so", ndk.create_shared) with open("deploy_graph.json", "w") as fo: fo.write(graph.json()) with open("deploy_param.params", "wb") as fo: fo.write(nnvm.compiler.save_param_dict(params)) ``` deploy_lib.so, deploy_graph.json, deploy_param.params will go to android target. ## TVM Runtime for Android Target Refer [here](https://github.com/dmlc/tvm/blob/master/apps/android_deploy/README.md#build-and-installation) to build CPU/OpenCL version flavor TVM runtime for android target. From android java TVM API to load model & execute can be refered at this [java](https://github.com/dmlc/tvm/blob/master/apps/android_deploy/app/src/main/java/ml/dmlc/tvm/android/demo/MainActivity.java) sample source.
