Error: Cannot find module '/path/to/my/application/node_modules/sqlite3/lib/binding/electron-v1.4-linux-x64/node_sqlite3.node'

Using Ubuntu 16.04 with Node 7.1.0 and Electron 1.4.12.

Install and Create Emulators using AVDMANAGER and SDKMANAGER

About

• The goal of this gist is to quickly pre-install a range of system images to provide our project teams the ability to run emulators on a range of API levels, from API 19 to API 28.
  • These can be run locally or on the base build agent.
• Note: X86 is the fastest architecture for emulators, though x86_64 would probably be better to test against because most phones are 64 bit now.
• We create two sets of emulators here, one set with pixel hardware emulation and one set with default oem emulation.

See: Google Documentation on Start the emulator from the command line for more info
