From cca1d0eb77bf8ba4bc6045f532ad1affc12cded4 Mon Sep 17 00:00:00 2001 From: genieocode <291563113+genieocode@users.noreply.github.com> Date: Sun, 14 Jun 2026 19:22:10 +0000 Subject: [PATCH 1/3] Add Agentic Coding feature with GitHub integration and local agentic loops This change introduces a new Agentic Coding feature to the Gallery app: - GitHub Authentication: Support for Personal Access Tokens. - Project Management: Ability to create and manage coding projects linked to GitHub repositories. - Agentic Workspace: Multi-turn chat interface with file tree navigation and planning panel. - Coding Tools: Agent can read/write files, list directories, and create PRs. - Unified Diff Viewer: Users can review and approve file changes before they are committed. - Persistent Agent Memory: Conversation history and task plans are stored per project. - Documentation: Added docs/agentic_coding.md with setup instructions. Note: A mock persistence layer is used for projects and memory to ensure build stability in the current environment, but the architecture is ready for Room integration. --- Android/src/app/build.gradle.kts | 4 + .../codingagent/CodingAgentTask.kt | 126 +++++++++++ .../customtasks/codingagent/CodingTools.kt | 155 +++++++++++++ .../codingagent/CodingWorkspaceScreen.kt | 204 ++++++++++++++++++ .../codingagent/CodingWorkspaceViewModel.kt | 160 ++++++++++++++ .../customtasks/codingagent/DiffViewer.kt | 112 ++++++++++ .../com/google/ai/edge/gallery/data/Tasks.kt | 1 + .../data/codingagent/CodingAgentDaos.kt | 34 +++ .../edge/gallery/data/codingagent/MockDaos.kt | 50 +++++ .../edge/gallery/data/codingagent/Project.kt | 32 +++ .../ai/edge/gallery/di/DatabaseModule.kt | 44 ++++ .../ai/edge/gallery/di/NetworkModule.kt | 54 +++++ .../ai/edge/gallery/network/GitHubService.kt | 94 ++++++++ .../gallery/ui/github/GitHubLoginScreen.kt | 156 ++++++++++++++ .../ui/projects/ProjectManagementScreen.kt | 174 +++++++++++++++ .../ui/projects/ProjectManagementViewModel.kt | 87 ++++++++ .../google/ai/edge/gallery/CodingAgentTest.kt | 39 ++++ Android/src/gradle/libs.versions.toml | 12 +- docs/agentic_coding.md | 40 ++++ 19 files changed, 1577 insertions(+), 1 deletion(-) create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/customtasks/codingagent/CodingAgentTask.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/customtasks/codingagent/CodingTools.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/customtasks/codingagent/CodingWorkspaceScreen.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/customtasks/codingagent/CodingWorkspaceViewModel.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/customtasks/codingagent/DiffViewer.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/data/codingagent/CodingAgentDaos.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/data/codingagent/MockDaos.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/data/codingagent/Project.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/di/DatabaseModule.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/di/NetworkModule.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/network/GitHubService.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/ui/github/GitHubLoginScreen.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/ui/projects/ProjectManagementScreen.kt create mode 100644 Android/src/app/src/main/java/com/google/ai/edge/gallery/ui/projects/ProjectManagementViewModel.kt create mode 100644 Android/src/app/src/test/java/com/google/ai/edge/gallery/CodingAgentTest.kt create mode 100644 docs/agentic_coding.md diff --git a/Android/src/app/build.gradle.kts b/Android/src/app/build.gradle.kts index ad38c63a0..3094d26a3 100644 --- a/Android/src/app/build.gradle.kts +++ b/Android/src/app/build.gradle.kts @@ -110,6 +110,10 @@ dependencies { implementation(libs.firebase.messaging) implementation(libs.androidx.exifinterface) implementation(libs.moshi.kotlin) + implementation(libs.retrofit) + implementation(libs.retrofit.gson) + implementation(libs.okhttp) + implementation(libs.okhttp.logging) kapt(libs.hilt.android.compiler) testImplementation(libs.junit) androidTestImplementation(libs.androidx.junit) diff --git a/Android/src/app/src/main/java/com/google/ai/edge/gallery/customtasks/codingagent/CodingAgentTask.kt b/Android/src/app/src/main/java/com/google/ai/edge/gallery/customtasks/codingagent/CodingAgentTask.kt new file mode 100644 index 000000000..ec09fc13e --- /dev/null +++ b/Android/src/app/src/main/java/com/google/ai/edge/gallery/customtasks/codingagent/CodingAgentTask.kt @@ -0,0 +1,126 @@ +/* + * Copyright 2025 Google LLC + * + * Licensed under the Apache License, Version 2.0 (the "License");
