Is it no longer possible to build an Android app with Wappler?

cgrulke · May 25, 2023, 6:50pm

Ive followed the how to doc exactly, tried following the video on the Why Wappler Youtube channel exactly, read every community post, tried every Gradle version, every SDK, tried both Capacitor and Cordova, and relentlessly Googled the errors and I cannot get my Wappler app to run on the Android Studio emulator.

I find this incredibly concerning as this is a main selling point for Wappler and as of now I am starting to think it is no longer possible. It is definitely no longer possible to achieve this as shown in the how to doc.

This is the error I keep coming to, if anyone can help me get this working correctly I will be very grateful as I am insanely frustrated with this whole experience.

I am on MacOS M1

The same error also showing when I open the app in Android Studio

What am I missing here? Is there any way to make this work?

Hi @cgrulke, not sure if this is the issue, but from my experience you need to be running an emulator/Android with API version 31. Yours is showing API 33.

Scroll to “STEP 6 - Android testing” in this post Musings on Mobile App Development in Wappler with CORS

Thank you although I have tried 31 along with every other sdk version. The same error arises every time. I’ve configured it every way from Sunday and nothing makes it work,

Above is just an example showing the error I get every time.

kfawcett · May 26, 2023, 2:47pm

Is this your issue? What version of Android Studio are you running?

kfawcett · May 26, 2023, 2:56pm

I’m not sure the location since you’re on Mac, but can you open your Wappler project and look in the Android directory for the gradle folder?

What is the version in the gradle-wrapper.properties?

cgrulke · May 26, 2023, 3:34pm

@kfawcett I am using Flamingo with Capacitor 5.0.4 with Gradle 8. The namespace issue is what keeps coming up.

And yes I can get there. Is there something I should insert into the properties file?

kfawcett · May 26, 2023, 8:36pm

What version shows in gradle-wrapper.properties?

Can you change it to the version I show in my screenshot above?

cgrulke · May 26, 2023, 9:36pm

@kfawcett Ah yes, when I use Gradle 7.4.2 I then get an error saying minimum gradle version required is 7.5…then if I go to a higher version, the error says minimum 7.6 and so on, then when I get all they way up to 8, the namespace error comes up

kfawcett · May 27, 2023, 12:34am

welp… I’m getting an error now as well. It’s been about a month since I worked on Android, so something has definitely changed.

Error running your project for android!

cgrulke · May 27, 2023, 1:29am

@kfawcett ouch! That sucks. Thank you so much for trying to help me on this. There has to be a solution somewhere.

Hopefully @George or @Teodor can shed some light on this

kfawcett · May 27, 2023, 2:55am

I managed to get it to launch by updating the following properties in variables.gradle from 32 to 33. Still, not going to fix your issue though.

   compileSdkVersion = 33
    targetSdkVersion = 33

brad · May 27, 2023, 3:11am

Hi Keith,

Are you able to build and successfully run the emulator in Wappler?

I can work on my app and send to the app store successfully, but I have to build and use the emulator in Android Studio.

kfawcett · May 27, 2023, 3:11am

What version do you have in build.gradle dependcies? Maybe you could use 7.2.1 like I have below?

  classpath 'com.android.tools.build:gradle:7.2.1'
  classpath 'com.google.gms:google-services:4.3.13'

kfawcett · May 27, 2023, 3:12am

Hey Brad, yes, I am able to build and run via Wappler.

cgrulke · May 27, 2023, 7:43pm

Did you get that to work? I kept getting an error that says minimum version of Gradle required is 7.5

kfawcett · May 30, 2023, 3:07pm

Hey @cgrulke, can you answer this?

cgrulke · May 30, 2023, 6:06pm

@kfawcett When I tried 7.2.1 and each of the other versions (I tried them all) I kept getting an error saying minimum Gradle version required 7.5. Then when I install 7.5 I get the same error saying 7.6 is required.

Right now I am thinking this is a problem with Android Studio Flamingo. I have completely uninstalled it and will tinker with older versions. Im not sure if it will work but I can’t think of anything else to try. I’ll let you know how it goes.

kfawcett · May 31, 2023, 2:02am

Did you make the change in the build.gradle file or gradle-wrapper.properties? I don’t know if changing either will work, just curious about what happens for each.

That may be the issue, I’m running Electric Eel.

HeikoK · May 31, 2023, 6:06am

Sorry, missed that discussion.
Yes, Flamingo causes problems…
Eel works.
