变更

app_current() previously delegated to adbutils, which reads window focus first and, on Android 13+, falls back to the last ACTIVITY in dumpsys activity top; floating windows, secondary displays and still-alive background apps could therefore be reported as current. It now parses dumpsys activity activities, prefers the primary display, skips tasks marked visible=false, reads topResumedActivity/mResumedActivity from the first visible task and extracts the matching app ProcessRecord pid. The adbutils path remains as a fallback for keyguard, screen-off or unusual vendor output, so DeviceError semantics are unchanged. app_wait(front=True) and wait_activity() benefit without API changes.

改动

• uiautomator2/init.py: added a dumpsys activity activities parser for visible tasks (display, visibility, resumed activity and pid) and used it in _AppMixIn.app_current() before the existing adbutils fallback
• tests/test_app_current.py: added unit tests with real dumpsys shapes for Android 10 and 14, floating/background tasks, secondary displays, hidden-only output, unparseable output and the DeviceError path

Closes #1085
