android - CameraX 配置不正确。最可能的原因是您没有在构建中包含默认实现，例如“camera-camera2”

Question

从 androidx.camera:camera-view:1.0.0-alpha32 更新后至androidx.camera:camera-view:1.1.0-beta01使用 CameraX 时收到下一个错误

camerax_version = "1.0.2"

// CameraX
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:1.1.0-beta01"

错误

java.lang.IllegalStateException: CameraX is not configured properly. The most likely cause is you did not include a default implementation in your build such as 'camera-camera2'.
    at androidx.camera.core.CameraX.<init>(CameraX.java:109)
    at androidx.camera.lifecycle.ProcessCameraProvider.getOrCreateCameraXInstance(ProcessCameraProvider.java:181)
    at androidx.camera.lifecycle.ProcessCameraProvider.getInstance(ProcessCameraProvider.java:167)

Answer 1

它失败了，因为您对各种 androidx.camera.* 库有不同的版本。
如果你检查这个:
https://developer.android.com/jetpack/androidx/releases/camera
它有以下描述:

From 1.1.0-beta01, all CameraX libraries will align the same version number. This will help developers track versions much easier and reduce the complexity of large version compatibility matrix.

因此，您需要对所有 camerax 库使用相同的版本。
