Android手机运行闪退 about yolov5_ncnn HOT 4 OPEN

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

需要安卓8.0（好像7.0也行）。有什么具体错误信息嘛
