HuaweiMediaStoreLocationValidationQuirk

implements Quirk

 java.lang.Object

↳androidx.camera.core.internal.compat.quirk.HuaweiMediaStoreLocationValidationQuirk

Overview

Quirk that displays a notification when an image in android.provider.MediaStore has been deleted.

When triggering an image capture, the ImageCapture use case validates the save location before starting the image capture pipeline. Validating a save location that is a in android.provider.MediaStore involves creating a new row in the user defined table, retrieving an output pointing to it, then attempting to open an java.io.OutputStream to it. The newly created row is deleted at the end of the verification. On Huawei devices, this last step results in the system displaying a notification informing the user that a photo has been deleted. In order to avoid this, validating the image capture save location to android.provider.MediaStore is skipped on Huawei devices. See b/169497925.
