Emulator Error Windows 10

Wappler General Bugs

I have had a problem running a project in an android emulator on windows 10. I have tried running the project on a android device and it works fine, will also run on an emulator in Android Studio.
I get the following error message, can you help?

Waiting for emulator to start…

There is a bug in the Cordova android tools about this. They solved it in their code base but i’m Not sure if it is published yet.

You can try the latest v 7.1.1

Hi George,

I tried your suggestion but it did not make any difference however I did find a solution that fixed the problem, see the following link;

https://stackoverflow.com/a/51079689 which made a change to the emulator.js file.

Also I notice that the build gradle is using gradle 4.1.

I have tried changing the line in the gradle-wrapper.properties file from distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip

to use gradle-4.6-all.zip but at the build it changes it back to 4.1.

I tried the build in Android Studio with 4.6 and it was fine, but as soon as I took it back into Wappler it changed it back to 4.1

Any suggestions on how to get it to use the lastest gradle?

Cheers Mark
