+# Running the App on a Device (ADB)
+
+Practical notes for launching the app on a connected device for manual/on-device testing.
+
+## Package & main activity
+
+| | Value |
+|---|---|
+| Debug package (Google flavor) | `com.tangem.wallet.debug` |
+| Main launcher activity | `com.tangem.tap.MainActivity` |
+| Application class | `com.tangem.tap.TangemHiltApplication` |
+
+## Launch the main screen (correct way)
+
+```bash
+adb shell am force-stop com.tangem.wallet.debug
+adb shell am start -n com.tangem.wallet.debug/com.tangem.tap.MainActivity
+```
+
+Verify the real screen is in the foreground:
+
+```bash
+adb shell dumpsys activity activities | grep -i topResumedActivity | grep -i tangem
+# expect: topResumedActivity=ActivityRecord{... com.tangem.wallet.debug/com.tangem.tap.MainActivity ...}
+```
+
+## Pitfall: do NOT launch via `monkey`
+
+```bash
+# ❌ ambiguous — may open the wrong screen
+adb shell monkey -p com.tangem.wallet.debug -c android.intent.category.LAUNCHER 1
+```
+
+Debug builds bundle **LeakCanary**, which registers its own `LAUNCHER` activity ("Leaks").
+The package therefore has **multiple** MAIN/LAUNCHER activities, so `monkey` (and
+`cmd package resolve-activity`) resolves to Android's `ResolverActivity` / the wrong entry
+and can open **LeakCanary instead of the app**. Always launch `MainActivity` explicitly with
+`am start -n`.
+
+List the launcher activities to confirm:
+
+```bash
+adb shell cmd package query-activities \
+  -a android.intent.action.MAIN -c android.intent.category.LAUNCHER \
+  | grep -iE "name=" | grep -i tangem
+```
+
+## Cold start vs warm start (matters for `Application.init()`)
+
+`TangemApplication.init()` (Hilt setup, and one-time bootstrap such as backend-auth device
+key generation + registration) runs **once per process**, on `Application.onCreate()`.
+
+- **Warm start** (process already alive / resumed from background): `init()` does **not** re-run.
+  You will NOT see the startup log banner `APP STARTED` or any one-time bootstrap logs.
+- **Cold start** (after `am force-stop`, or first launch): `init()` runs → look for the
+  `APP STARTED` banner in logcat (tag `TangemApplication`).
+
+To reliably observe anything that happens in `init()`, always `force-stop` first, then launch.
+
+> Note: `init()` runs on process start regardless of *which* activity brought the process up
+> (even LeakCanary's). So process-scoped logs are still valid on a wrong-activity launch — but
+> for observing actual app UI/flows, launch `MainActivity` explicitly.
+
+## Build & install (Google debug)
+
+```bash
+./gradlew :app:assembleGoogleDebug
+adb install -r app/build/outputs/apk/google/debug/app-google-debug.apk
+```
+
+## Product flavors
+
+Flavors: `google`, `huawei` (dimension `services`); default dev flavor is `google`.
+Build types: `debug`, `mocked`, `internal`, `external`, `release`.
