[android-porting] Making Custom SDK and Integrating Car API/Vehicle Services -Android N(7.1.1)
Hi, I'm a newbie to Android AOSP. I was trying to utilize the Car API/Services/HAL provided by Google from Android N version onwards(https://source.android.com/devices/automotive/). My aim is to develop App that uses this Car API.Android N Standard SDK that was downloaded as a part of Android Studio doesn't include those APIs mentioned in link. I verified it by try importing packages(import android.car )..But Car package was not listing at all.I tried building a custom SDK Steps I followed : 1. Downloaded Google AOSP-Android N from git. 2. Verify the existence of those Car services/API are located in /home/symbio/myandroid/packages/services/Car 3. Builded SDK with commands in order : 1 . build/envsetup.sh 2. lunch sdk-eng 3.mm/mma /packages/services/Car 4.make sdk But even I couldn't find or do importing those Car services in newly builded SDK. I'm kind of stuck.Which all makefile Shall I need to change so as to reflect the same ? Any lead will be highly appreciated.
