Let me check which controls need the same fix and create a comprehensive solution. Based on my analysis:\n\n## Initial Assessment - Similar Drawable Mutation Issues\n\n**Issue Summary**: PR #33071 fixed a crash in SearchBar on Android caused by modifying shared Drawables without calling `Mutate()` first. The same pattern exists in several other controls.\n\n**Affected Controls**:\n1. **ActivityIndicator** - `ActivityIndicatorExtensions.cs` line 30\n2. **Entry/Editor** (Clear button) - `EditTextExtensions.cs` line 230\n3. **Switch** - `SwitchExtensions.cs` lines 17, 31\n4. **MauiRippleDrawable** - `MauiRippleDrawableExtensions.cs` line 128 (different - creating new drawable)\n\n**Fix Pattern** (from PR #33071):\n```csharp\ninternal static void SafeSetTint(ImageView? imageView, Color color)\n{\n if (imageView?.Drawable is not Drawable drawable)\n return;\n\n var safe = drawable.Mutate();\n safe.SetTint(color);\n imageView?.SetImageDrawable(safe);\n}\n```\n\n**Reproduction Plan**:\n- Since the original issue is hard to reproduce (only happens in large apps with many screens), I'll apply the same defensive fix pattern\n- Test on Android to ensure tinting still works correctly\n- Platform: Android only (this is an Android-specific issue)\n\n**Next Steps**:\n1. Create a shared helper method for safe drawable mutation\n2. Apply it to ActivityIndicator, Entry/Editor, and Switch\n3. Test each control's color changes work correctly\n\nAny concerns about this approach?", "supportThemeIcons": false, "supportHtml": false, "supportAlertSyntax": false, "uris": {} } ], "agent": { "id": "copilotcli", "name": "cli", "fullName": "Background Agent", "description": "Delegate tasks to a background agent.", "isDefault": false, "isCore": false, "isDynamic": true, "slashCommands": [ { "name": "delegate", "description": "Delegate chat session to cloud agent and create associated PR" } ], "locations": [ "panel" ], "modes": [ "agent", "ask" ], "disambiguation": [], "metadata": { "themeIcon": { "id": "collection" } }, "capabilities": { "supportsFileAttachments": true, "supportsProblemAttachments": true, "supportsToolAttachments": false, "supportsSymbolAttachments": true, "supportsSearchResultAttachments": true, "supportsSourceControlAttachments": true }, "canAccessPreviousChatHistory": true, "extensionId": { "value": "GitHub.copilot-chat", "_lower": "github.copilot-chat" }, "extensionVersion": "0.35.2", "extensionDisplayName": "GitHub Copilot Chat", "extensionPublisherId": "GitHub" }, "timestamp": 1766433671948, "responseId": "response_0f70cf0e-331a-4550-911f-1d38b8bdac00", "responseMarkdownInfo": [], "modelState": { "value": 1, "completedAt": 1766433671949 }, "contentReferences": [], "codeCitations": [], "timeSpentWaiting": 0 }, { "requestId": "request_b2331076-fb4e-4bf2-84c1-5d73b02c85b3", "message": { "text": "proceed", "parts": [ { "range": { "start": 0, "endExclusive": 7 }, "editorRange": { "startLineNumber": 1, "startColumn": 1, "endLineNumber": 1, "endColumn": 8 }, "text": "proceed", "kind": "text" } ] }, "variableData": { "variables": [] }, "response": [ { "value": "I'll proceed with applying the safe drawable mutation fix to the other affected controls.", "supportThemeIcons": false, "supportHtml": false, "supportAlertSyntax": false, "uris": {} }, { "kind": "toolInvocationSerialized", "toolCallId": "toolu_vrtx_0151joErZP4DsZtAt24YEJHj", "toolId": "Read", "invocationMessage": { "value": "Read [](file:///Users/kubaflo/Desktop/maui/src/Core/src/Platform/Android)", "supportThemeIcons": false, "supportHtml": false, "supportAlertSyntax": false, "uris": { "file:///Users/kubaflo/Desktop/maui/src/Core/src/Platform/Android": { "$mid": 1, "external": "file:///Users/kubaflo/Desktop/maui/src/Core/src/Platform/Android", "path": "/Users/kubaflo/Desktop/maui/src/Core/src/Platform/Android", "scheme": "file" } } }, "isConfirmed": true, "isComplete": true, "source": { "type": "external", "label": "External" }, "generatedTitle": "Read Android platform source files" }, { "value": "Now let me create a shared utility class for the safe drawable mutation pattern and apply it to all affected controls:", "supportThemeIcons": false, "supportHtml": false, "supportAlertSyntax": false, "uris": {} }, { "kind": "toolInvocationSerialized", "toolCallId": "toolu_vrtx_01QT2JvAN7Du6ccYeeMTf3VZ", "toolId": "Create File", "invocationMessage": { "value": "Path already exists", "uris": {} }, "isConfirmed": true, "isComplete": true, "source": { "type": "external", "label": "External" }, "generatedTitle": "Path already existed" }, { "value": "Let me check the existing file:", "supportThemeIcons": false, "supportHtml": false, "supportAlertSyntax": false, "uris": {} }, { "kind": "toolInvocationSerialized", "toolCallId": "toolu_vrtx_01WPBCkXssrsyVCYY8W6esHN", "toolId": "Read", "invocationMessage": { "value": "Read [](file:///Users/kubaflo/Desktop/maui/src/Core/src/Platform/Android/DrawableExtensions.cs)", "supportThemeIcons": false, "supportHtml": false, "supportAlertSyntax": false, "uris": { "file:///Users/kubaflo/Desktop/maui/src/Core/src/Platform/Android/DrawableExtensions.cs": { "$mid": 1, "external": "file:///Users/kubaflo/Desktop/maui/src/Core/src/Platform/Android/DrawableExtensions.cs", "path": "/Users/kubaflo/Desktop/maui/src/Core/src/Platform/Android/DrawableExtensions.cs", "scheme": "file" } } }, "isConfirmed": true, "isComplete": true, "source": { "type": "external", "label": "External" }, "generatedTitle": "Read DrawableExtensions.cs file" }, { "value": "Good!

The same pattern existed in several other controls.\n\n### 🔧 Files Modified\n\n**Core Platform Extensions** (src/Core/src/Platform/Android/):\n1. **DrawableExtensions.cs** - Added safe drawable mutation helper methods\n - `SafeSetTint()` - for ImageView and Drawable\n - `SafeSetColorFilter()` - for Drawable with color filter\n - `SafeClearColorFilter()` - for clearing color filters\n - All methods call `Mutate()` before modifying drawable properties\n\n2. **ActivityIndicatorExtensions.cs** - Fixed IndeterminateDrawable color handling\n - Uses `SafeSetColorFilter()` instead of direct `SetColorFilter()`\n - Uses `SafeClearColorFilter()` instead of direct `ClearColorFilter()`\n\n3. **EditTextExtensions.cs** - Fixed Entry/Editor clear button color handling\n - Uses `SafeSetColorFilter()` and `SafeClearColorFilter()`\n - Properly reassigns drawable after mutation\n\n4. **SwitchExtensions.cs** - Fixed Switch track and thumb color handling\n - TrackDrawable uses `SafeSetColorFilter()` / `SafeClearColorFilter()`\n - ThumbDrawable uses `SafeSetColorFilter()`\n - Properly reassigns drawables after mutation\n\n5. **SearchViewExtensions.cs** - Applied same fix as PR #33071\n - Search icon tinting uses `SafeSetTint()`\n - Cancel button uses `SafeSetTint()`\n - Placeholder color uses `SafeSetTint()`\n\n### ✅ UI Tests Created\n\n**Test Page**: `src/Controls/tests/TestCases.HostApp/Issues/Issue33070.xaml[.cs]`\n- Tests ActivityIndicator color changes\n- Tests Entry TextColor changes (affects clear button)\n- Tests Switch ThumbColor and OnColor changes\n- Tests SearchBar TextColor, PlaceholderColor, and CancelButtonColor changes\n- Includes stress test with 50 rapid color changes across all controls\n\n**NUnit Tests**: `src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue33070.cs`\n- `ActivityIndicatorColorChangeShouldNotCrash()` - 5 iterations\n- `EntryTextColorChangeShouldNotCrash()` - 5 iterations\n- `SwitchColorChangeShouldNotCrash()` - 5 iterations\n- `SearchBarColorChangeShouldNotCrash()` - 5 iterations\n- `RapidColorChangesShouldNotCrash()` - 50 iterations stress test\n\n### 📋 Testing\n\nTo run the tests:\n\n```powershell\n# Android (where the crash occurs)\npwsh .github/scripts/BuildAndRunHostApp.ps1 -Platform android -TestFilter \"Issue33070\"\n\n# iOS (to verify no regression)\npwsh .github/scripts/BuildAndRunHostApp.ps1 -Platform ios -TestFilter \"Issue33070\"\n```\n\n### 🔍 Root Cause\n\nAndroid shares Drawable resources for memory efficiency. Modifying a shared drawable without calling `Mutate()` first causes race conditions and crashes in large apps with many screens, especially when:\n- Multiple views reference the same drawable resource\n- Colors are changed frequently (navigation, theme changes)\n- The app has many screens/fragments\n\n### 💡 Solution\n\nThe fix follows Android's recommended pattern:\n1. Call `drawable.Mutate()` to create a mutable copy\n2. Apply tint/color filter to the mutated copy\n3. Reassign the mutated drawable back to the view\n\nThis ensures each view gets its own drawable instance that can be safely modified.\n\nEOF" }, "language": "bash", "terminalCommandState": { "timestamp": 1766433672027 } } }, { "value": "Perfect!
