Errors running and even the sample does not run

[dwhiteddsoft]

We noticed our usage of msal_flutter started to fail. As we went back to figure out what was wrong, we simply ran your example app and it errors out in the same way which makes us think it is an environment error. Here is the error when it is run:

Environment looks like:

ext.kotlin_version = '1.3.50' (in. build.gradle)

Any thoughts appreciated as we are a little surprise it suddenly stopped working

I believe it's due to com.microsoft.identity.client:msal upgrade, because after change the line below in build.gradle
implementation 'com.microsoft.identity.client:msal:1.0.+'
to
implementation 'com.microsoft.identity.client:msal:1.0.0'

the example app works again.

However i am not sure how to fix it in msal-flutter yet. But as a temporary solution, you can force the version number in android/build.gradle of your project. Example:

allprojects {
configurations.all {
resolutionStrategy.force "com.microsoft.identity.client:msal:1.0.0"
}
}

Sorry about that and the delay in replying had been a bit swamped, but I'll test it this week to see what the issue might be, and will attempt to specify the exact msal version to see if that helps.

[iron9light]

I guess it's because it's not compatible with msal 1.0.1.
And I've tried to change msal version to 1.1.0, not work.

[mswehli]

Sorry for the delay in replying, been a very busy winter period.
yes, as @erikgkr found (thanks for that by the way, doubt i would have found that on my own! :) ), it seems to be something with the change from 1.0.0 to the newer versions. I've update the package now to force it to only use 1.0.0, as to be honest it was a mistake on my part not to have specified it exactly anyway. >_<
I've published the changes, but please have a look and let me know if it fixes it for you. The new package version is 1.0.0+3 and should fix the android issues. Tested it locally and worked for me.

Oh, just please make sure to use kotlin version 1.3.30 or later, especially if you get the error "java.lang.NoSuchFieldError: No static field msalApp of type Lcom/microsoft/identity/client/IMultipleAccountPublic"

[ericgkr]

@mswehli i confirm that with 1.0.0+3 no need to enforce com.microsoft.identity.client:msal version in android/build.gradle any more. Many thanks!

It is still not working for me..

I followed all the steps you say to do for android set up in the package readme.

I use the latest version of the package : msal_flutter: ^1.0.0+3

And if I add in the appname > android>app>build.gradle the following as suggested above:
implementation 'com.microsoft.identity.client:msal:1.5.+'
or implementation 'com.microsoft.identity.client:msal:1.0.0'
The app takes forever to build and doesn't in the end build throwing the following error:

`FAILURE: Build failed with an exception.

• What went wrong:

I also tried to clone the project and run the example app, still gives the same error as explained above.

Some update on this?
