KindleHe opened a new issue #4884: [android_deploy] crash is caused by `Module.load` func while running App on Android Device with URL: https://github.com/apache/incubator-tvm/issues/4884 I install the apk in vivo X6S A, according to the [Android TVM Demo](https://github.com/apache/incubator-tvm/tree/master/apps/android_deploy) vivo X6S A is arm64-v8a with android-22, so I modify config.mk as following: ``` APP_ABI = arm64-v8a APP_PLATFORM = android-22 # whether enable OpenCL during compile USE_OPENCL = 0 # the additional include headers you want to add, e.g., SDK_PATH/adrenosdk/Development/Inc ADD_C_INCLUDES = # the additional link libs you want to add, e.g., ANDROID_LIB_PATH/libOpenCL.so ADD_LDLIBS = ``` However, I run app in device, the app crash immediately, so I add some lines for debug: ``` Log.i(TAG, "libCacheFilePath=" + libCacheFilePath); Module modelLib = Module.load(libCacheFilePath); Log.i(TAG, "Finish Module.load"); ``` Then, I use `adb logcat -b main -v time>app.log` command to capture crash on android device machine to get the following log file [app.log](https://github.com/apache/incubator-tvm/files/4205184/app.log) Here is some important information of app.log ``` 02-14 23:38:51.469 I/MainActivity(28024): libCacheFilePath=/data/data/org.apache.tvm.android.demo/cache/tvm4j_demo_-856121318/deploy_lib_cpu.so 02-14 23:38:51.469 W/System.err(28024): Try loading tvm4j from native path. 02-14 23:38:51.469 W/System.err(28024): Try loading tvm4j-linux-x86_64 from native path. 02-14 23:38:51.469 W/System.err(28024): [WARN] TVM native library not found in path.

Meanwhile, the app.log says `Caused by: java.lang.NullPointerException`. So, I locate the crash is caused by `Module.load` func or `libCacheFilePath`, however `libCacheFilePath=/data/data/org.apache.tvm.android.demo/cache/tvm4j_demo_-856121318/deploy_lib_cpu.so`, and I find `deploy_lib_cpu.so` indeed exist in ``` ➜ app git:(dev/kindlehe/walk-through) ✗ find ./ -name deploy_lib_cpu.so .//build/intermediates/merged_assets/release/out/deploy_lib_cpu.so .//build/intermediates/merged_assets/debug/out/deploy_lib_cpu.so .//build/intermediates/assets/release/deploy_lib_cpu.so .//build/intermediates/assets/debug/deploy_lib_cpu.so .//src/main/assets/deploy_lib_cpu.so ``` Finally, I conclude the crash is caused by `Module.load` func. But, I don' t know how to sovle the crash problem, begging for your kind-hearted help sincerely!
