[android] Update gradle.properties #30543

rmarinho · 2025-07-10T17:56:24Z

Description of Change

This pull request introduces updates to build configurations, Android compatibility, and namespace adjustments to improve project maintainability and compatibility with newer tools and frameworks.

Build Configuration Updates:

Updated gradle-wrapper.properties to use Gradle version 8.13, ensuring compatibility with the latest features and optimizations.
Changed the Android Gradle Plugin version in build.gradle to 8.11.1 for better integration with Gradle 8.x.
Added pluginManagement block in settings.gradle to centralize plugin repositories and changed repositoriesMode to PREFER_PROJECT for improved dependency resolution.

Android Compatibility Improvements:

Updated compileSdk and targetSdk versions to 35 in maui/build.gradle for compatibility with the latest Android SDK.
Enabled R8 full mode and non-transitive R classes in gradle.properties to optimize resource handling and reduce APK size.
Adjusted sourceCompatibility and targetCompatibility in maui/build.gradle to Java 17 for leveraging modern Java features.

Namespace and Resource Adjustments:

Removed the package attribute from AndroidManifest.xml to align with the updated namespace configuration.
Updated resource references in PlatformInterop.java and MauiCustomViewTarget.java to use the new namespace microsoft.maui. [1] [2]

Environment Variable Updates:

Added DOTNET_HOST_PATH environment variable in dotnet.cake to address a Windows-specific issue with Dev18.

The key error is this line:

I would open the project in latest stable Android Studio, and see if it prompts to update various things: gradle, Android gradle plugin, etc.

The error itself looks like the build used an older build-tools that contains an older aapt2.exe. And it doesn't know how to open API-35's android.jar.

jonathanpeppers · 2025-07-14T18:07:05Z

src/Core/AndroidNative/maui/build.gradle

-        sourceCompatibility JavaVersion.VERSION_1_8
-        targetCompatibility JavaVersion.VERSION_1_8
+        sourceCompatibility JavaVersion.VERSION_17
+        targetCompatibility JavaVersion.VERSION_17


I would undo this line for now, we still build with Java source targeting 1.8, see for example:

dotnet/android@e517d53

I think it could cause build warnings like:

Invoke-customs are only supported starting with Android O (--min-api 26)

@jonathanpeppers seems those changes made it worst.. maybe we still need the namespace change.

@rmarinho no I think the error to fix is:

> Namespace not specified. Specify a namespace in the module's build file: /mnt/vss/_work/1/s/src/Core/AndroidNative/maui/build.gradle. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

Did Copilot hallucinate and put it on the wrong element?

maui/src/Core/AndroidNative/maui/build.gradle

Lines 5 to 7 in 3c54f94

    
           android { 
        
               compileSdk 35 
        
               namespace "microsoft.maui"

You should also name it com.microsoft.maui to match what we had before:

maui/src/Core/AndroidNative/maui/src/main/AndroidManifest.xml

Line 2 in 9f08fd3

    
           <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.microsoft.maui">

Then you should be able to undo the change to the R class.
