Android development. Virtualdevice commands and Cordova.

I just gathered here commands I need for development:

List all your emulators:

emulator -list-avds

Run one of the listed emulators:

emulator @nameofyouremulator

where emulator is under:

${ANDROID_SDK}/tools/emulator

To deploy on specific device use:

• Target specification. This includes --emulator, --device, or --target=<targetID>.

PostgreSQL on Mac OSX

Installing postgreSQL was so hard for mac. Because there are zero complete tutorials?? Or they require I know postgreSQL commands beforehand. This tutorial is for total noob.

Steps:

1. $ brew update
2. $ brew doctor
3. $ brew install postgresql

Start or Stop postgresql

$ brew services start postgresql

$ brew services stop postgresql

THEN for MAC creating default db failed, so use command

$ createdb

after that you can login to psql using

$ psql

You can also setup database to specific folder using:

$ psql -d template1

To exit the psql command line use:

CTRL + D
