RK3399 android_deploy demo cant't find libGLES_mali.so

Questions
#1

my android deploy app can’t find “libGLES_mali.so” (can be found in the /system/vendor/lib64/egl/libGLES_mali.so)

the flowing is my configuration

APP_ABI = arm64-v8a

APP_PLATFORM = android-17

# whether enable OpenCL during compile
USE_OPENCL = 1

# the additional include headers you want to add, e.g., SDK_PATH/adrenosdk/Development/Inc
ADD_C_INCLUDES = CL

# the additional link libs you want to add, e.g., ANDROID_LIB_PATH/libOpenCL.so
ADD_LDLIBS = libOpenCL.so #copy from /system/vendor/lib64/libOpenCL.so

the following is the error log

I found a solution, create a library directory, put all related libraries(pull from rk3399) in, and then reference the directory in gradle.

This method solves the library loading problem, but there are still other problems running in my RK3399. When the “run” method is executed, the system throws an exception.

E/libc++abi: terminating with uncaught exception of type dmlc::Error: [05:36:28] /Users/dinghuanghao/Project/tvm/apps/android_deploy/app/src/main/jni/jni_helper_func.h:194: Do NOT know how to handle return type code 1044873685

It may be a little late. Android doesn’t allow vendor libraries to be loaded as they belong to different classloader namespace. Instead google recommends to package all the required vendor private libraries with the app. https://developer.android.com/about/versions/nougat/android-7.0-changes.html#ndk
