In Android 8.1 we can build and install the application in the vendor partition in the AOSP build tree.
by using LOCAL_MODULE_PATH := $(TARGET_OUT_VENDOR_APPS)
After the installation, I found that the .apk file resides in the following path vendor/app/SampleApp/SampleApp.apk and data files are available in the data/data/.
And lib(pre-build .so libs) folder pointing to the vendor/app/SampleApp/SampleApp/libs but there is no folder like that.
I have extracted the application and found the lib files are available in .apk file.
What is the difference between the vendor application build and system build?
