Mark Complete Clear Progress. Completed New. Build a desktop weather app with Compose for Desktop! Computer users take it for granted that their systems can do more than one thing at a time. They assume that they can continue to work in a word processor, while other applications download files, manage the print queue, and stream audio.
Even a single application is often expected to do more than one thing at a time. For example, that streaming audio application must simultaneously read the digital audio off the network, decompress it, manage playback, and update its display. Mandate that for concurrent operation of cameras, the camera framework must open camera devices 3. This allows camera providers to allocate resources accordingly. When you make the updates above, it can create a problem with a behavior allowed by the MultiViewTest.
The test testDualCameraPreview doesn't configure sessions only after opening all cameras. It follows this sequence:. Third-party apps might depend on this behavior.
Because the camera HAL won't know the complete set of camera IDs being opened for concurrent operation before configuring sessions, it could be hard for it to allocate hardware resources assuming there is some competition for them.
