CameraX 未正确配置。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

更新到

androidx.camera:camera-view:1.1.0-beta01

后，我在使用

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。

如果您检查此：
https://developer.android.com/jetpack/androidx/releases/camera

它有以下描述：

从1.1.0-beta01开始，所有CameraX库将对齐相同版本 数字。这将帮助开发人员更轻松地跟踪版本 降低大版本兼容性矩阵的复杂度。

因此您需要对所有camerax库使用相同的版本。

Answer 2

该错误是因为您使用了同一库的不同 api 版本，在库中找不到新版本的camera-camera2 api 。

val cameraVersion = "1.3.1"
implementation("androidx.camera:camera-lifecycle:$cameraVersion")
implementation("androidx.camera:camera-camera2:$cameraVersion")
implementation("androidx.camera:camera-view:$cameraVersion")
implementation("androidx.camera:camera-core:$cameraVersion")

此代码运行良好，没有任何错误
