Building AOSP source for Angler (Nexus 6P)

source build/envsetup.sh
lunch aosp_angler-eng
make -j16   # Uses 16 threads.

The output will be in android-6.0.1_r45/out/target/product/angler/

Flashing a phone

With the phone connected over USB the following:

• Go to Settings and click on About Phone 7 times to enable developer mode.
• Go to Settings > Developer Options and Enable USB Debugging.
• If it is the first time you are flashing the device, you will have to unlock the device. Go to Settings > Developer Options and enable OEM Unlocking.
• Then flash the build using:

adb reboot bootloader
fastboot flashing unlock # Only needed for the first time to unlock the device.
cd out/target/product/angler
fastboot -w flashall

Getting view hierarchies

With the phone connected over USB the following:

• Start the custom view server on the phone.

adb shell dumpsys activity start-view-server

• Use ADB to forward a port on your local machine to port 1699 on the phone.

adb forward tcp:<port> tcp:1699

• Connect to the local port using TCP. The example below uses a Linux utility called nc.

nc localhost <port>

• Send the String “d\n” to request a dump of the view hierarchy. Each response will contain the view hierarchy in JSON format followed by a line with the string “RICO_JSON_END”.
• Send the String “s\n” to stop the server.
