Type-checked against the API 36 framework jar (tools/androidcheck); assembleDebug still needs the SDK Co-Authored-By: Claude Fable 5.1 Claude-Session: https://claude.ai/code/session_01Vyo2hxtfWppNVyy99Q8GmZ --- app/src/main/AndroidManifest.xml | 109 ++++++++++ .../com/thatsimpletech/assist/AssistApp.kt | 51 +++++ .../assist/a11y/AssistAccessibilityService.kt | 43 ++++ .../assist/a11y/NodeExecutor.kt | 194 ++++++++++++++++++ .../assist/a11y/TreeObserver.kt | 54 +++++ .../thatsimpletech/assist/a11y/TreeWalker.kt | 159 ++++++++++++++ .../assist/approval/AndroidApprovalSurface.kt | 49 +++++ .../assist/approval/ApprovalNotifier.kt | 87 ++++++++ .../assist/approval/ApprovalReceiver.kt | 24 +++ .../assist/approval/ApprovalRequests.kt | 28 +++ .../assist/approval/OverlayCard.kt | 103 ++++++++++ .../assistant/AssistInteractionService.kt | 46 +++++ .../assist/audit/AndroidSqlExecutor.kt | 45 ++++ .../thatsimpletech/assist/kill/KillSwitch.kt | 34 +++ .../assist/kill/KillSwitchTile.kt | 31 +++ .../notif/AssistNotificationListener.kt | 89 ++++++++ .../assist/secrets/KeystoreSecretStore.kt | 76 +++++++ .../assist/task/TaskController.kt | 12 ++ .../assist/task/TaskForegroundService.kt | 67 ++++++ .../thatsimpletech/assist/ui/MainActivity.kt | 126 ++++++++++++ app/src/main/res/values/strings.xml | 13 ++ .../res/xml/accessibility_service_config.xml | 14 ++ app/src/main/res/xml/interaction_service.xml | 8 + .../main/res/xml/network_security_config.xml | 10 + 24 files changed, 1472 insertions(+) create mode 100644 app/src/main/AndroidManifest.xml create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/AssistApp.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/a11y/AssistAccessibilityService.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/a11y/NodeExecutor.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/a11y/TreeObserver.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/a11y/TreeWalker.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/AndroidApprovalSurface.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/ApprovalNotifier.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/ApprovalReceiver.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/ApprovalRequests.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/OverlayCard.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/assistant/AssistInteractionService.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/audit/AndroidSqlExecutor.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/kill/KillSwitch.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/kill/KillSwitchTile.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/notif/AssistNotificationListener.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/secrets/KeystoreSecretStore.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/task/TaskController.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/task/TaskForegroundService.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/ui/MainActivity.kt create mode 100644 app/src/main/res/values/strings.xml create mode 100644 app/src/main/res/xml/accessibility_service_config.xml create mode 100644 app/src/main/res/xml/interaction_service.xml create mode 100644 app/src/main/res/xml/network_security_config.xml diff --git a/app/src/main/AndroidManifest.xml b/app/src/main/AndroidManifest.xml new file mode 100644 index 0000000..dd964e8 --- /dev/null +++ b/app/src/main/AndroidManifest.xml @@ -0,0 +1,109 @@ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + diff --git a/app/src/main/kotlin/com/thatsimpletech/assist/AssistApp.kt b/app/src/main/kotlin/com/thatsimpletech/assist/AssistApp.kt new file mode 100644 index 0000000..5ee83d9 --- /dev/null +++ b/app/src/main/kotlin/com/thatsimpletech/assist/AssistApp.kt @@ -0,0 +1,51 @@ +package com.thatsimpletech.assist + +import android.app.Application +import android.database.sqlite.SQLiteDatabase +import com.thatsimpletech.assist.a11y.AssistAccessibilityService +import com.thatsimpletech.assist.approval.AndroidApprovalSurface +import com.thatsimpletech.assist.approval.ApprovalNotifier +import com.thatsimpletech.assist.approval.OverlayCard +import com.thatsimpletech.assist.audit.AndroidSqlExecutor +import com.thatsimpletech.assist.core.policy.PolicyPack +import com.thatsimpletech.assist.core.secrets.SecretStore +import com.thatsimpletech.assist.secrets.KeystoreSecretStore +import java.io.File + +class AssistApp : Application() { + override fun onCreate() { + super.onCreate() + Graph.init(this) + } +} + +/** + * The app's object graph, by hand.

full task wiring - CloudPlanner: one brain-tier chat call per step, metered; spend cap turns into an ask line so the turn ends cleanly - AuditListener: every step, approval and model call is an INSERT
