任务':react-native-camera:compileDebugJavaWithJavac‘执行失败

Question

我正在使用React创建应用程序--本机，并在Android设备上进行测试。添加了react本机相机模块后，会发生以下错误：

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':react-native-camera:compileDebugJavaWithJavac'.在“构建->运行任务”(Android )。

关于Java编译器，大约有20-30个错误，所有这些错误都显示如下：error: package android.support.annotation does not exist、error: package android.support.v4.util does not exist、error: package android.support.media does not exist等，或者是error: cannot find symbol class SparseArrayCompat、error: package Pools does not exist、error: cannot find symbol variable ExifInterface，这些错误在错误文件中签入时与import android.support.v4.util.ArrayMap;-import类语句有关。

我的android/build.gradle文件：

buildscript {
    ext {
        minSdkVersion = 26
        compileSdkVersion = 28
        targetSdkVersion = 27
        supportLibVersion = 28
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'
    }
}

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
        mavenLocal()
        jcenter()
        /*maven {

            if (abi != null) {  // null for the universal-debug, universal-release variants
                output.versionCodeOverride =
                        versionCodes.get(abi) * 1048576 + defaultConfig.versionCode
            }

    implementation "com.android.support:support-v4:28.0.0"

}

我试图解决以下问题：

• 我将android-support-v4.jar文件添加到./libs文件夹中。
• 我添加了"google()“或maven链接到依赖项。
• 我尝试过更改minSdkVersion、compileVersion等，但是我想这可能是主要的问题。
• 重建这个项目也没有成功。
• 将项目迁移到Android。

My版本: 28

分级版本: 4.10.1

类路径'com.android.tools.build: gradle :3.3.1‘(将gradle版本降级为3.1.0无效)。

Answer 1

使用应用程序构建gradle属性，在react原生相机build.gradle文件中更改minsdk版本和编译in版本。

android/build.gradle

buildscript {
    ext {
      buildToolsVersion = "28.0.3"
      minSdkVersion = 16
      compileSdkVersion = 28
      targetSdkVersion = 28
      supportLibVersion = "28.0.0"
      googlePlayServicesVersion = "16.1.0" // or set latest version
      androidMapsUtilsVersion = "0.5+"
    }
}

反应-本地摄像头/android/build.gradle

android {
   compileSdkVersion 28
   buildToolsVersion "28.0.3"

defaultConfig {
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName computeVersionName()
}
lintOptions {
    abortOnError false
}
}

Answer 2

结帐平台的具体要求..。例如，在android上检查权限，至少应该是：

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

Answer 3

在根目录中运行：
