您好，作者，尝试过几台Android手机，运行就闪退了。分别是红米note4，和小米6，Android系统是6.0以上的。权限有手动打开。

已解决问题，上面这个错误java.lang.RuntimeException: Unable to get provider androidx.camera.camera2.impl.Camera2Initializer 需要在build.gradle 下，把def camerax_version = "1.0.0-alpha05"改成def camerax_version = "1.0.0-alpha04" 另个地方需要注意的是，OpenCV的so调用。在build.gradle下添加 sourceSets.main { jniLibs.srcDir 'libs' }

repositories {
    mavenCentral()
    jcenter()
    flatDir { dirs 'libs' }
}

且在main下添加jniLib把OpenCV的so添加进来，就可以正常使用了

谢谢，为什么我这没问题...
