From One Mobile Screen to Offline Recovery

Your starting point

Use the mobile project already available to you. A simulator or supported local environment is enough to begin; physical-device checks can follow.

• Basic state and records.
• A mobile project that can run in an available simulator or local test environment.

Your finish line

You can build a small mobile flow, separate draft and saved values, and verify what happens when network access is absent or the app is interrupted.

Stack up four small wins

1. STEP 1 OF 4

   Define one screen and one tap

   Write a short habit-list brief with one tap action, one invalid-input case, and a clear statement of what should survive reopening.

   Bro tip: Name the exact habit affected by a tap and what reopening should show. Make the reset or completion policy explicit in your brief.

   What you’ll learn

   • Visible state
   • Stable record identity
   • Local versus shared storage
   You’re ready to move on when

   The brief names a specific record affected by the tap and an observable fresh-launch result.

2. STEP 2 OF 4

   Build a locally saved single screen

   Complete the Pocket Habit List Starter. Keep the first version offline and verify the stated completion policy.

   Bro tip: Tap one of two similar habits and check that only its state changes. Reopen the app through your supported test flow to compare saved values.

   What you’ll learn

   • Touch feedback
   • Validation
   • Basic persistence
   You’re ready to move on when

   Tapping changes only the chosen item, valid addition happens once, and reopening restores the documented state.

3. STEP 3 OF 4

   Navigate and edit without accidental changes

   Complete the Pocket Recipe Cards Practice. Use fictional recipes and test leaving an unfinished edit as deliberately as saving one.

   Bro tip: Change a recipe, discard it, then reopen it. Compare with a saved edit so the two actions cannot quietly behave the same.

   What you’ll learn

   • List-to-detail flow
   • Separate drafts
   • Save, discard, and interruption policy
   You’re ready to move on when

   Discard leaves saved data unchanged, invalid input preserves the draft, and reopening shows accepted changes.

4. STEP 4 OF 4

   Finish an offline recovery journey

   Complete the Offline Field Checklist Workshop. Test a run without network access, interruption during editing, and export of one chosen run.

   Bro tip: Use two clearly different test runs. Interrupt one, reopen offline, then export only the chosen run and inspect its items and notes.

   What you’ll learn

   • Lifecycle transitions
   • Invalid local data
   • Explicit export
   You’re ready to move on when

   The saved run reopens offline without duplication and the exported content belongs only to the chosen run.

Your build lineup

1. Pocket Habit List Starter

   Build one small mobile screen with clear state and local persistence, using the project’s existing platform setup.

2. Pocket Recipe Cards Practice

   Practice list-to-detail navigation, editing, and recoverable drafts with local sample content.

3. Offline Field Checklist Workshop

   Build a small checklist that recovers from interruptions and can export user-created data explicitly.

Watch it. Then build it.

Start with a worked example, then connect the recording to your own small, checkable build. Videos open on their creator’s or publisher’s website.

   Android Basics with Compose — Unit 1: Your first Android app

   Android Developers · Google

   Start with Kotlin programming basics, learn the Android development environment, and build a screen with text and images.

   For step 1: Define one screen and one tap

   Before watching: No prior programming for the introductory Kotlin lessons. Stack: Kotlin and Jetpack Compose; Android Studio and an emulator or device are needed for practice.

   Watch, then try

   Watch the introductions before each practice section. Identify which composable displays a value and how the preview relates to the running app.

   A mixed course with embedded videos and hands-on codelabs, not a continuous film. Start with its videos; later path steps add state, editing, and persistence beyond this first screen.

   Android Basics with Compose — Use Room for data persistence

   Android Developers · Google

   Learn how local database records are read and updated through Room, with videos and an Android inventory-style exercise.

   For step 4: Finish an offline recovery journey

   Before watching: Know Kotlin classes, Compose state and navigation, ViewModels, coroutines, basic Flow, and introductory SQL. Complete the earlier Android Basics units and the Introduction to SQL pathway first. Stack: Kotlin, Compose, Room, and SQLite.

   Watch, then try

   Separate the screen's displayed values from saved records. Compare what happens before and after reopening the app with no network.

   This mixed video-and-codelab pathway supports local persistence without a cloud service. Apply the ideas to our checklist; draft recovery, export, and damaged-data handling still need their own checks.
