Hi all,
new day, new problems When I start my application like yesterday, I got the message

[IDE message - 10:10:18]
No device found.
Please use B4A-Bridge to connect to a device or start an emulator.

I had connected a smart phone via USB cable to charge it, but I don't want to use it for testing but rather the emulator. I I run [Tools] > [Restart ADB server] the following pops up:

How can I told the IDE, that I want to use the emulator instead of a connected smart phone?

Short addendum: When I run the command "adb.exe devices" I get an empty list

 

[teddybear]

You don't want to use the phone for testing , did you install an emulator on your pc?

The error was

ERROR | Running multiple emulators with the same AVD

You don't want to use the phone for testing , did you install an emulator on your pc?

Yes, I did, see attached file

 

[teddybear]

Did you start an emulator and then compile & run your app?

 

[bfw]

I deleted the contents of the .android\avd directory and created a new avd in the avd manager. After that it worked again

 

[teddybear]

Has your problem solved?

Anyway you can keep your phone connected (or more than one) and even run one or more emulators (different ones).
When compiling B4A will request which device must be targeted for installation.
CTRL-P to clean the project will ensure this request.
