CameraX crashes when get cameraProviderFuture

Question

With the official CameraX example on fourth step - Implement Preview use case:

     // Used to bind the lifecycle of cameras to the lifecycle owner
       val cameraProvider: ProcessCameraProvider = cameraProviderFuture.get()

I've got a crash:

I'm using non stock device with two cameras that works fine with Camera2Basic example. In the project sets the latest camerax libs.:

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    def camerax_version = '1.0.0-beta06'
    implementation "androidx.camera:camera-core:${camerax_version}"
    implementation "androidx.camera:camera-camera2:$camerax_version"
    implementation "androidx.camera:camera-lifecycle:$camerax_version"
    implementation 'androidx.camera:camera-view:1.0.0-alpha13'
    implementation 'androidx.camera:camera-extensions:1.0.0-alpha13'

I've tried setup manually CameraXConfig.Provider, but with the same issue on get cameraProviderFuture.

Anybody have an example of manually configuration ProcessCameraProvider with binding to specific camera device? Maybe any ideas how to setup preview with specific camera?

Answer 1

You have to use the exact version of their camerax otherwise it might not work.

def camerax_version = "1.0.0-beta03"
// CameraX core library using camera2 implementation
implementation "androidx.camera:camera-camera2:$camerax_version"
// CameraX Lifecycle Library
implementation "androidx.camera:camera-lifecycle:$camerax_version"
// CameraX View class
implementation "androidx.camera:camera-view:1.0.0-alpha10"

Answer 2

In my case the problem is that camera has EXTERNAL HAL. According to official CameraX team answer its not yet supported for now. To check camera HAL:

adb shell dumpsys media.camera

and check for android.info.supportedHardwareLevel in the output, it could be something like:

...
== Camera HAL device device@3.4/external//dev/video0 (v3.4) static information: ==
  Resource cost: 100
  Conflicting devices: None
  API1 info:
    Has a flash unit: false
    Facing: Front
    Orientation: 0
  API2 camera characteristics:
    Dumping camera metadata array: 52 / 52 entries, 2224 / 2224 bytes of extra data.
      Version: 1, Flags: 00000000
      android.info.supportedHardwareLevel (150000): byte[1]
        [EXTERNAL ]
...

To avoid such limitation I injected custom CameraDeviceSurfaceManager with the required camera resolution and sizes for my case . The solution is here.
