|
## Notas
|
|
|
|
Sources `adb_wsl.sh` from its own directory, so `ADB` and `ANDROID_SDK_WIN` env vars
|
|
are respected as with all other android_* functions.
|
|
|
|
Exit codes:
|
|
- `0` — screenshot captured successfully.
|
|
- `1` — missing output path, screencap produced empty file, or adb error.
|
|
- `3` — no device/emulator connected (propagated from `adb_pick_serial`).
|
|
|
|
The emptiness check (`! -s`) handles the case where `adb exec-out` exits 0 but writes
|
|
zero bytes (e.g. device locked, screencap permission denied). In that case the file is
|
|
removed and exit 1 is returned.
