Error on android emulator

[shaharsol]

Can you figure out what's wrong? I'm using an emulator with API version 29, maybe that's too high?

I need to update the library zoom sdk.

[kevinbayes]

@shaharsol try the latest commit and let me know.

[shaharsol]

@kevinbayes now it works when i run your sample app (should the video looks like this?):

However, in my app, that uses the plugin as a dependency in this manner:

  flutter_zoom_plugin:
    git:
      url: git://github.com/decodedhealth/flutter_zoom_plugin.git

I still get the same exception, though I'm pretty sure I've rebuilt it, coz since your upgrade I had to follow on and change the compileSdkVersion and the targetSdkVersion to 29...

@shaharsol yes that is the correct view for the emulator using the camera. You should test on device to get a feel of what it would look like on a real phone.

One question has your app been upgraded to androidx?

And the following lines added to your gradle properties:

org.gradle.jvmargs=-Xmx1536M
android.useAndroidX=true
android.enableJetifier=true

[shaharsol]

@kevinbayes

Added those lines to gradle.properties and the targetSdk is 29 so AFAIK it's enough to migrate it to androidx.

Getting the same error message, only this time it's the adnroidx class (Landroidx/fragment/app/FragmentActivity)that it's DEF isnn't found:

@shaharsol can you create a repository with your setup that simulates the error? Then I can help out on fixing it.

[shaharsol]

@kevinbayes added you as collaborator, invite is here https://github.com/shaharsol/sanghaline-flutter/invitations
To reproduce:

1. sign in with username kevin@gnift.com, password 123456
2. navigate to instructors
3. click on the first one (Vidad)
4. navigate to Calendar (on the top tab)
5. click the first item, this should start the zoom session

Thanks!
