Add android_ui: drive Android apps by element, never by coordinates
Shared across every repo with an Android surface (screen-locker's workout_app, todo, dufs-cloud/app). Works against a plain release APK on a physical device over adb — no root, no emulator, no Flutter debug connection, no app changes. Driving an app by tapping pixel positions read off a screenshot fails in ways that look like success. All observed in one session (2026-08-10) verifying workout_app's Firebase restore: * A tap aimed at a password field landed with the field unfocused. The typed password went nowhere and NOTHING errored — the next screenshot just showed an empty box. type_into/type_into_field now re-read the field and raise. * Opening the soft keyboard moved a field from y=1572 to y=1319, so a coordinate captured one step earlier was already wrong. Every action re-resolves the element immediately before acting. * A widget behind the keyboard reports its LAID-OUT position (1549) not its real one (1939) — a 390px error that taps a letter key and reports success. keyboard_is_up() distinguishes "absent" from "behind the keyboard", and tap closes the keyboard first. * KEYCODE_BACK is a route pop in Flutter, not a keyboard dismiss: it navigated out of Settings and discarded typed credentials, twice. dismiss_keyboard tries ESCAPE then BACK and verifies via dumpsys input_method. * `input text` inserts at the cursor, so typing over a filled field produced "canary@example.com321krzychu@gmail.com". Fields are cleared first. * uiautomator returns ONLY the focused EditText nodes while a Flutter text field has focus, and stays that way across retries — so a naive retry loop never converges. Partial trees are retried and the best result kept. * An EMPTY EditText has no text, content-desc or resource-id, so a "must be labelled" filter drops the very field you need to fill in. Editable nodes are kept regardless and addressable by position. Ambiguity is an error rather than a silent first-match: `tap "Back"` correctly refuses when "OFFLINE BACKUP" is also on screen. Its own test suite caught a real bug in _escape: backslash sat inside the escape loop, so "&" became "\\&" and a password containing shell metacharacters would have been typed wrong.

# android_ui — drive Android apps by element, never by coordinates
|
||||
|
||||
Shared across every repo with an Android surface (`~/screen-locker`'s
|
||||
workout_app, `~/todo`, `~/dufs-cloud/app`). Works against a plain release APK
|
||||
on a physical device over `adb` — no root, no emulator, no Flutter debug
|
||||
connection, no change to app source.
|
||||
|
||||
## Why
|
||||
|
||||
Driving an app by tapping pixel positions read off a screenshot fails in ways
|
||||
that look like success. All of these were observed in one session
|
||||
(2026-08-10), verifying the workout app's Firebase restore:
|
||||
|
||||
| Failure | What it looks like |
|
||||
| ------------------------------- | -------------------------------------------------------------------------------------------------------------- |
|
||||
| Tap lands on an unfocused field | Typed text goes nowhere; nothing errors; the next screenshot shows an empty box |
|
||||
| Soft keyboard opens | A field moves 1572 → 1319; every coordinate captured a step earlier is wrong |
|
||||
| Widget sits behind the keyboard | The tree reports its _laid-out_ position (1549) not its real one (1939) — a 390px error that taps a letter key |
|
||||
| Screenshot scaling | The harness renders 1080×2400 at 900×2000, so every read coordinate needs a manual ×1.2 |
|
||||
| Typing into a filled field | `input text` inserts at the cursor: `old@example.comnew@example.com` |
|
||||
|
||||
Two device quirks are handled rather than documented, because both produced
|
||||
false results before they were understood:
|
||||
|
||||
- `uiautomator dump` returns **only the `EditText` nodes** while a Flutter text
|
||||
field holds focus. The button you are about to tap is simply missing, and it
|
||||
stays missing across retries — a naive retry loop never converges.
|
||||
- `KEYCODE_BACK` is a **route pop** in Flutter, not a keyboard dismiss. It
|
||||
navigates out of the screen and discards typed input.
|
||||
|
||||
## Use
|
||||
|
||||
```bash
|
||||
export PYTHONPATH=~/testsAndMisc
|
||||
python3 -m python_pkg.android_ui dump
|
||||
python3 -m python_pkg.android_ui find "Connect Firebase"
|
||||
python3 -m python_pkg.android_ui --exact tap "Back"
|
||||
python3 -m python_pkg.android_ui wait "Connected." --timeout 30
|
||||
python3 -m python_pkg.android_ui focus
|
||||
```
|
||||
|
||||
Every subcommand exits non-zero and names the query on failure, so a script can
|
||||
tell a real failure from a successful no-op.
|
||||
|
||||
```python
|
||||
from python_pkg.android_ui import AndroidUi
|
||||
|
||||
ui = AndroidUi() # or AndroidUi(serial="23181JEGR08034")
|
||||
ui.tap("Connect Firebase", exact=True)
|
||||
ui.type_into_field(0, "kuhy@example.com") # verifies the field changed
|
||||
ui.wait_for("Connected.", timeout=30)
|
||||
```
|
||||
|
||||
## Guarantees
|
||||
|
||||
- **Ambiguity is an error.** A query matching 0 or >1 elements raises; it never
|
||||
silently acts on the first match. (`tap "Back"` correctly refuses when
|
||||
"OFFLINE BACKUP" is also on screen — use `--exact`.)
|
||||
- **Coordinates are never reused.** Every action re-reads the tree immediately
|
||||
before acting, and `tap` closes the keyboard first when one is up.
|
||||
- **Typing is verified.** `type_into` / `type_into_field` re-read the field and
|
||||
raise if the contents did not change. They clear before typing, so a filled
|
||||
field is replaced, not appended to.
|
||||
- **Empty fields are findable.** An empty `EditText` has no text, content-desc
|
||||
or resource-id; it is kept anyway, addressable by position via
|
||||
`editable_fields()` / `type_into_field(index, …)`.
|
||||
- **Partial trees are retried,** and `keyboard_is_up()` distinguishes "element
|
||||
absent" from "element behind the keyboard".
|
||||
|
||||
## Known gaps
|
||||
|
||||
- A widget with no accessibility label cannot be targeted at all. The workout
|
||||
app's Settings gear is one — that is an a11y bug in the app, and this tool
|
||||
surfacing it is the point. Add a `Semantics(label: …)` and it becomes
|
||||
addressable.
|
||||
- Scrolling is not yet modelled: a widget outside the viewport is not in the
|
||||
tree. Scroll with `adb shell input swipe` first, or add `scroll_to()`.

Drives a real device by *identity* (text, content-desc, resource-id) rather

|
||||
three ways this package exists to remove, all of them observed on 2026-08-10
|
||||
while verifying the workout app's Firebase restore:
|
||||
|
||||
* **A mis-tap is silent.** A tap at ``(540, 1705)`` aimed at a password field
|
||||
landed with the field unfocused; the typed password went nowhere and nothing
|
||||
errored. :func:`~python_pkg.android_ui.driver.AndroidUi.type_into` verifies
|
||||
the field's text actually changed and raises when it did not.
|
||||
* **Layout shifts invalidate coordinates.** Opening the soft keyboard moved a
|
||||
field from y=1572 to y=1319, so a coordinate captured one step earlier was
|
||||
already wrong. Every action re-reads the tree immediately before acting.
|
||||
* **Screenshots are expensive and unassertable.** A full-page PNG per step
|
||||
costs far more than the element list it stands in for, and cannot be
|
||||
grepped. :meth:`~python_pkg.android_ui.driver.AndroidUi.dump` returns text.

Two device quirks are handled rather than documented, because both produced

false results before they were understood:

field holds focus — the button you are about to tap is simply missing, and it
|
||||
stays missing across retries, so a naive retry loop never converges.
|
||||
* ``KEYCODE_BACK`` is treated by Flutter as a route pop, not a keyboard
|
||||
dismiss: it navigated out of Settings and discarded typed input, twice.
