KindleHe commented on issue #4884: [android_deploy] CRASH caused by `Module.load` func while running App on Android Device with URL: https://github.com/apache/incubator-tvm/issues/4884#issuecomment-586994657 @tqchen Yes! I find the answer finally! Your answer is right! TVM4J is Java Frontend for TVM Runtime, and the CRASH occurs at calling Module.load func. As [#4871](https://github.com/apache/incubator-tvm/pull/4871) said, runtime PackedFunc is changed at this commit. Namely, the corresponding Java interface for TVM runtime changed. So, even I synced my branch with remote master newest branch and rebuild the android apk, I get the same CRASH due to I forget to rebuild TVM4J to get a new java interface after [#4871](https://github.com/apache/incubator-tvm/pull/4871). The key is **rebuild TVM4J** before **rebuild the android apk** I am glad to learn more about Java as a Java newcomer and thanks for your kind help very much! > Thanks for your quick reply! > > As you said in [[REFACTOR][PY][API-Change] Polish tvm.runtime, tvm.runtime.module API update](https://github.com/apache/incubator-tvm/pull/4837#issue-372188411) > > ``` > API changes wrt to runtime.Module > tvm.module.load -> tvm.runtime.load_module > tvm.module.enabled -> tvm.runtime.enabled > tvm.module.system_lib -> tvm.runtime.system_lib > ``` > > However, the [tvm.module related codes](https://github.com/apache/incubator-tvm/blob/1dcf8a16ee3a93dff5ffc1ad1a66892eda03ef13/apps/android_deploy/app/src/main/java/org/apache/tvm/android/demo/MainActivity.java#L184) did not change yet, even I keep my dev branch the same with newest master branch. > in `src/main/java/org/apache/tvm/android/demo/MainActivity.java` > > ``` > Module modelLib = Module.load(libCacheFilePath); > ``` > > Finally, I get the same crash error ,and I m not sure what's the problem? > Could you offer me some further help? > > > Can you see if #4871 resolved your problem, please make sure to rebuild the native app along with the java source
