Android Virtual Device: tips and tricks

One of the Android Developer’s best friends is the emulator (aka AVD). It allows us to simulate some behaviors, like calling, sending SMS messages, simulate a specific location and much more.

Creating an emulator

Creating an Android Virtual Device is very simple, just make sure you have the system image of the Android version you need to simulate installed.

You can see a list of available options on the Android website:

Emulator keyboard mapping

In general I use keyboard mappings for everything. I think it makes me more productive. AVD has some nice keyboard mappings to simulate the real experience closer to a real device.

One of the most important tools for the Android developer is logcat. Logcat is a simple way to see the system logs and debugging output from device/emulator. You can use logcat from an ADB shell to view the log messages.
