I am trying to add an application in AOSP source through app source code, not by apk . My application is simple hello world application which I have developed in Android Studio. I have wrote its Android.mk, placed it in packages/app/myapplication/Android.mk. Registered application package name in aosp_source_code/build/target/product/handheld_system.mk Did I make any mistakes in Android.mk file? or am I missing any steps.

Here is code of my Android.mk

include $(CLEAR_VARS)

LOCAL_PACKAGE_NAME := Myapplication
LOCAL_MODULE_TAGS := optional
LOCAL_PRIVILEGED_MODULE := true
LOCAL_CERTIFICATE := platform

LOCAL_PRIVATE_PLATFORM_APIS := true

LOCAL_SRC_FILES := $(call all-java-files-under, src/main/java)
LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/src/main/res
LOCAL_MANIFEST_FILE := src/main/AndroidManifest.xml

LOCAL_DEX_PREOPT := false
LOCAL_PROGUARD_ENABLED := disabled

LOCAL_USE_AAPT2 := true

LOCAL_STATIC_ANDROID_LIBRARIES := \
    android-arch-lifecycle-extensions \
    android-support-v7-recyclerview \
    android-support-v7-appcompat \
    android-support-constraint-layout
include $(BUILD_PACKAGE)

As i saw on your build.gradle file, you probably need to link androidx.appcompat:appcompat, androidx.constraintlayout:constraintlayout, androidx.navigation:navigation-ui and androidx.navigation:navigation-fragment in your Android.mk

Example

LOCAL_STATIC_ANDROID_LIBRARIES := \
    androidx.appcompat_appcompat \
    androidx-constraintlayout_constraintlayout \
    androidx-navigation_navigation-ui \
    androidx-navigation_navigation-fragment \
    ...

But androidx-navigation_navigation-ui and androidx-navigation_navigation-fragment may available or not available depend on your AOSP build system. You should check by yourself to ensure these libraries available (usually located in prebuilts directory). In case these libraries not available, you need to download them manually then add them to AOSP build system manually.
