title: Vendor app in android AOSP build tree
body: <p>In Android 8.1 we can build and install the application in the vendor partition in the AOSP build tree.
  by using <code>LOCAL_MODULE_PATH := $(TARGET_OUT_VENDOR_APPS)</code>
  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/. </p>
  
  <p>And lib(pre-build .so libs) folder pointing to the vendor/app/SampleApp/SampleApp/libs but there is no folder like that.</p>
  
  <p>I have extracted the application and found the lib files are available in .apk file.</p>
  
  <p>What is the difference between the vendor application build and system build?</p>
