I have not modifyied the tvm4j dependency declare in app/build.gradle. I just use gradle to build directly. I built successfully.
And then I dev_tools/gen_keystore.sh and dev_tools/sign_apk.sh to get the tvmrpc-release.apk.
However, when I install tvmrpc-release.apk in my android phone, it occurs the Parsing error：Problems in parsing software packages.
