react-native-camera：Android 应用程序崩溃没有错误

如何解决react-native-camera：Android 应用程序崩溃没有错误

我已将 react-native-camera 添加到我的应用程序中。创建使用 RNCamera 的组件后，每次我尝试运行我的应用程序（使用 react-native run-android）时，它都会请求必要的权限（相机和音频），然后立即崩溃而不输出任何错误消息。

这是我的 package.json：

{
  "main": "index.js","scripts": {
    "android": "react-native run-android","ios": "react-native run-ios","web": "expo start --web","start": "react-native start","test": "jest"
  },"dependencies": {
    "@react-native-community/async-storage": "^1.12.1","@tensorflow-models/mobilenet": "^2.0.4","@tensorflow/tfjs": "^3.3.0","@tensorflow/tfjs-react-native": "^0.5.0","expo": "~40.0.0","expo-camera": "~9.1.0","expo-constants": "^10.0.1","expo-gl": "~9.2.0","expo-gl-cpp": "~9.2.0","expo-splash-screen": "~0.8.0","expo-status-bar": "~1.0.3","expo-updates": "~0.4.0","mobx": "^6.1.8","react": "16.13.1","react-dom": "16.13.1","react-native": "~0.63.4","react-native-camera": "^3.43.0","react-native-fs": "^2.16.6","react-native-gesture-handler": "~1.8.0","react-native-reanimated": "~1.13.0","react-native-screens": "~2.15.0","react-native-unimodules": "~0.12.0","react-native-web": "~0.13.12"
  },"devDependencies": {
    "@babel/core": "~7.9.0","babel-jest": "~25.2.6","jest": "~25.2.6","react-test-renderer": "~16.13.1"
  },"jest": {
    "preset": "react-native"
  },"private": true
}

这是我的 build.gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    ext {
        buildToolsversion = "29.0.2"
        minSdkVersion = 21
        compileSdkVersion = 29
        targetSdkVersion = 29
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:3.5.3")
        classpath("com.google.gms:google-services:4.3.5")

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS,Obj-C sources,Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }
        maven {
            url("$rootDir/../node_modules/expo-camera/android/maven")
        }
        maven {
            url 'https://www.jitpack.io'
        }



        google()

有关为什么会发生这种情况或如何解决此问题的任何信息将不胜感激！谢谢:)

更新：我试过在同一个 repo 中使用 expo-camera（我读到 react-native-camera 是建立在 expo-camera 上的），而且效果很好。

编辑：这是运行 adb logcat 的输出：pastebin.com/yWM5Mat8。

解决方法

<uses-permission android:name="android.permission.CAMERA" />

在 AndroidManifest.xml 文件中的相机权限上方添加。检查一次后。

仔细阅读粘贴图，这似乎是罪魁祸首：

03-31 21:51:16.152 13039 13039 E unknown:ViewManager: Error while updating prop playSoundOnCapture
03-31 21:51:16.152 13039 13039 E unknown:ViewManager: java.lang.reflect.InvocationTargetException
... a bunch of traceback lines
03-31 21:51:16.152 13039 13039 E unknown:ViewManager: Caused by: java.lang.NoSuchMethodError: No virtual method setPlaySoundOnCapture(Z)V in class Lorg/reactnative/camera/RNCameraView; or its super classes (declaration of 'org.reactnative.camera.RNCameraView' appears in /data/app/~~2TIdBhLTuyzCkV7CYFT2Mg==/com.chowtime-uS9KR34-elnZ0EmL_ovT3w==/base.apk!classes4.dex)

这个 github 问题可能是相关的：https://github.com/react-native-camera/react-native-camera/issues/2938#issuecomment-671436341 它似乎没有很好的解决方案，但表明如果 react-native-camera 和 expo-camera 都安装，就像它们看起来一样，就会发生冲突你的 package.json。如果它们依赖于不同版本的 com.google.android.cameraview.CameraView，您可能需要选择其中一种。
