building webrtc for android fails: loading build.ninja No such file or directory

[eeethenQ]

I want to compile an android version but encounter some problems when executing build_apprtc.

Here is the outcome:

Setting up build environment for Android
Export the base settings of GYP_DEFINES so we can define how we want to build
User has not specified any gyp defines so we proceed with default
ARMv7 with Neon Build

I have tried to sudo apt install ninja ninja-build but it doesn't work.

Could be missing glib dev? Try apt-get install libglib2.0-dev and see if that solves it.

Make sure all dependencies are installed. libglib2.0-dev libgtk2.0-dev libxtst-dev libxss-dev libpci-dev libdbus-1-dev libgconf2-dev
