Adding Pre-built Apk in AOSP crashes

• AOSP 10

• OpenVPN official App

I am trying to add OpenVPN app in AOSP but it crashes. I have checked it by installing in device, it works fine when I install it from playstore/f-droid or downloaded apk through adb install. When I add this apk in aosp source code it gets added in build AOSP (OS) but when I launch app after flashing AOSP in device it crashes on libraries, Then I added its required libraries in AOSP, but now its throwing other errors. AOSP (OS) is same in both scenarios. I have also tried other VPN apps but same issue with all. I have added other apps in AOSP those works fine but these VPN apps not working.

Here are adb logs of app crash

My problem is solved by @RickSanchez suggestion but I had to add two libraries in AOSP other given below make file by @RickSanchez

Make a folder named OpenVPN , put APK named OpenVPN.apk inside and the Android.mk below:

LOCAL_PATH := $(call my-dir)

my_archs := arm x86 arm64
my_src_arch := $(call get-prebuilt-src-arch, $(my_archs))

include $(CLEAR_VARS)
LOCAL_MODULE := OpenVPN
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_TAGS := optional
LOCAL_BUILT_MODULE_STEM := package.apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
LOCAL_SRC_FILES := OpenVPN.apk

LOCAL_PREBUILT_JNI_LIBS := \
  @lib/arm64-v8a/libc++_shared.so \
  @lib/arm64-v8a/libconceal.so \
  @lib/arm64-v8a/libfb.so \
  @lib/arm64-v8a/libfolly_futures.so \
  @lib/arm64-v8a/libfolly_json.so \
  @lib/arm64-v8a/libglog.so \
  @lib/arm64-v8a/libglog_init.so \
  @lib/arm64-v8a/libhermes-executor-debug.so \
  @lib/arm64-v8a/libhermes-executor-release.so \
  @lib/arm64-v8a/libhermes-inspector.so \
  @lib/arm64-v8a/libhttpcli.so \
  @lib/arm64-v8a/libimagepipeline.so \

  @lib/arm64-v8a/libreactnativeblob.so \
  @lib/arm64-v8a/libreactnativejni.so \
  @lib/arm64-v8a/libyoga.so

LOCAL_MODULE_TARGET_ARCH := $(my_src_arch)

include $(BUILD_PREBUILT)

Tip: I used this tool to generate the Android.mk automatically: https://github.com/northbright/genandroidmk

If that doesn't work for some reason, then unzip the libs from the APK into a local folder, and refer to the libs using relative path ( in LOCAL_PREBUILT_JNI_LIBS without the "@" sign, but only lib/arm64-v8a/libc++_shared.so )
