Android virtual device showing no device error.

When i run my app a windows pop ups shows no device.After avd processing it shows no emulator.

1 Answer

Hi Kapil,

When I try to run an app, I get the "Device Chooser" which lists the devices that are connected or there's a radio button for "Launch emulator". If there's no emulator defined, there's a little box with three dots next to the drop-down with [none] written in it. Click that.

That opens the AVD where you can create a new virtaul device. You can define what you want to emulate in there. Then, when you go back to run your app you should have the option to use that virtual device at runtime. If you've done that and the virtaul device doesn't immediately appear, try the drop-down in the Device Chooser as that might still be set to [none].

Let me know if that helps at all or let me know what you've tried already.

Steve.
