Android SDK and emulator tool
First make sure that you have access to the emulator tool from the command line. The emulator tool comes bundled with the Android SDK and the correct path to it is, from Android SDK folder:
Important: This should be the executable acessible in the command line, and not the one in tools/emulator.exe. This is a common problem that people face when using this tool, so check if you have the correct executable in your Path variable.
This article does not cover how to create a Android Virtual Device (AVD). Assuming that you have at least one AVD, let’s procced.
To have a list of the availables AVDs, run the command below:
emulator -list-avdsShows the list of AVDs installed
It should print the a list of AVD IDs. Grab the desired AVD ID (Ex.: Samsung_A30S_API_28) and let’s proceed.
Running the AVD
With the AVD ID in hands, execute the command below to run the emulator:
emulator @<AVD_ID>Replace the <AVD_ID> with the desired AVD ID selected in the previous section. It should look like this: emulator @Samsung_A30S_API_28
Do not forget to put an @ symbol right before the AVD ID.
That’s it. If everything go right the emulator window should open right after. If you have an error check if you are using the correct emulator tool (first section) or if you got the right AVD ID (List AVDs section).
