Beginnen Sie mit den Stack-Trace-Einstiegspunkten in androidx.camera.core.impl.CameraValidator.java, CameraSelector.java und CameraX.java, wobei Sie sich auf die Kamera-ID /dev/video0 und die fehlgeschlagene Validierung der Objektiv-Ausrichtung konzentrieren. Reproduzieren Sie das Protokoll auf dem betroffenen Gerät und ermitteln Sie anschließend die erwartete Behandlung dieser Kamera, bevor Sie den Fix und seine Verifizierung festlegen.
