Implementation Reference

• src/server/deepLinkTools.ts:116-122 (registration)

  Registers the MCP tool 'detectIntentChooser' with ToolRegistry, providing name, description, schema, and handler function.
  ToolRegistry.registerDeviceAware( "detectIntentChooser", "Detect system intent chooser dialog in the current view hierarchy", detectIntentChooserSchema, detectIntentChooserHandler, false // Does not support progress notifications );
• src/server/deepLinkTools.ts:63-79 (handler)

  The main handler function for the 'detectIntentChooser' tool. Instantiates DetectIntentChooser class, calls execute(), and formats the response.
  const detectIntentChooserHandler = async (device: BootedDevice, args: DetectIntentChooserArgs) => { try { const detectIntentChooser = new DetectIntentChooser(device); const result = await detectIntentChooser.execute(); return createJSONToolResponse({ message: `Intent chooser detection completed. Detected: ${result.detected}`, success: result.success, detected: result.detected, error: result.error, observation: result.observation }); } catch (error) { logger.error(`[detectIntentChooser] Failed to detect intent chooser: ${error}`); throw new ActionableError(`Failed to detect intent chooser: ${error}`); } };
• src/server/deepLinkTools.ts:15-16 (schema)

  Zod schema definition for the tool arguments (no parameters required).
  export const detectIntentChooserSchema = z.object({ });
• src/features/observe/DetectIntentChooser.ts:7-53 (helper)

  DetectIntentChooser class that performs screen observation and delegates detection to DeepLinkManager.
  export class DetectIntentChooser extends BaseVisualChange { private deepLinkManager: DeepLinkManager; constructor(device: BootedDevice, adb: AdbUtils | null = null) { super(device, adb); this.deepLinkManager = new DeepLinkManager(device); } /** * Execute intent chooser detection * @returns Promise with intent chooser detection results */ async execute(): Promise<IntentChooserResult> { return this.observedInteraction( async (observeResult: ObserveResult) => { try { const viewHierarchy = observeResult.viewHierarchy; if (!viewHierarchy) { return { success: false, error: "View hierarchy not found" }; } logger.info("[DetectIntentChooser] Starting intent chooser detection"); const detected = this.deepLinkManager.detectIntentChooser(viewHierarchy); logger.info(`[DetectIntentChooser] Intent chooser detection completed. Detected: ${detected}`); return { success: true, detected }; } catch (error) { logger.error(`[DetectIntentChooser] Failed to detect intent chooser: ${error}`); return { success: false, detected: false, error: error instanceof Error ? error.message : String(error) }; } }, { changeExpected: false } ); } }
• src/utils/deepLinkManager.ts:204-282 (helper)

  Core detection logic that traverses the view hierarchy and checks for text, class, and resource ID indicators of the intent chooser dialog.
  detectIntentChooser(viewHierarchy: ViewHierarchyResult): boolean { try { // If the hierarchy is empty, return false if (!viewHierarchy || !viewHierarchy.hierarchy || !viewHierarchy.hierarchy.node) { return false; } // Look for common intent chooser indicators const textIndicators = [ "Choose an app", "Open with", "Complete action using", "Always", "Just once" ]; const classIndicators = [ "com.android.internal.app.ChooserActivity", "com.android.internal.app.ResolverActivity" ]; const resourceIdIndicators = [ "android:id/button_always", "android:id/button_once", "resolver_list", "chooser_list" ]; // Get root nodes from the view hierarchy const rootNodes = this.elementUtils.extractRootNodes(viewHierarchy); // Check all nodes in the hierarchy for (const rootNode of rootNodes) { let foundIndicator = false; this.elementUtils.traverseNode(rootNode, (node: any) => { if (foundIndicator) {return;} const nodeProperties = this.elementUtils.extractNodeProperties(node); const nodeClass = nodeProperties.class || ""; const nodeText = nodeProperties.text || nodeProperties["content-desc"] || ""; const nodeResourceId = nodeProperties["resource-id"] || ""; // Check for class indicators for (const className of classIndicators) { if (nodeClass.includes(className)) { foundIndicator = true; return; } } // Check for text indicators (exact match) for (const text of textIndicators) { if (nodeText === text) { foundIndicator = true; return; } } // Check for resource ID indicators for (const resourceId of resourceIdIndicators) { if (nodeResourceId.includes(resourceId)) { foundIndicator = true; return; } } }); if (foundIndicator) { return true; } } return false; } catch (error) { logger.warn(`[DeepLinkManager] Error detecting intent chooser: ${error}`); return false; } }
