fixes#3872

Problem

We were not automatically injecting uuid to the MAUI Android apk, so developers would have to manually go in and editAndroidManifest.xml.

Solution

As proposed by@rafalka, we can inject the uuid to the Apk, and upload the proguard file with the same uuid.

Before

Before the fix, running in the MAUI project would upload the proguard file with the uuid, but it won't inject the uuid to the Android app.

After

We should now see the proguard file in Sentry with some uuid:

If we open the resulting APK in Android studio to inspect it'sAndroidManifest.xml, we can see that it correctly set themeta-data field:

Testing method

To test this change using oursamples/Sentry.Samples.Maui, we need to modifysrc/Sentry/buildTransitive/Sentry.targets file. If not using our sample MAUI project, ignore this step.

We have to remove the check whether this is a Sentry project or not. So delete theand [...] in line 72-73:

Next, ensureSentryUploadAndroidProguardMapping is set to true in your MAUI project's .csproj file:

    <SentryUploadAndroidProguardMapping>true</SentryUploadAndroidProguardMapping>

In the same file, enable Proguard. This is what I used:

  <PropertyGroup Condition="'$(Configuration)' == 'Release'">    <AndroidLinkTool>r8</AndroidLinkTool>    <AndroidLinkMode>Full</AndroidLinkMode>    <AndroidEnableProguard>true</AndroidEnableProguard>  </PropertyGroup>

Rundotnet publish -f net9.0-android35.0 -c Release in the MAUI project root.
