A prototype for a new Android Recent Apps switcher.
Currently can obtain Recent Apps screenshots when tethered to a computer.
Build and install app to Android 8.1 device from Android Studio. Instant Run should be disabled.
In adb, run
CLASSPATH="$(pm path net.zhuoweizhang.pill|sed -e s/^package//)" app_process /sdcard net.zhuoweizhang.pill.PillServer
which serves all recent app images over localhost HTTP. (This is obviously insecure.)
