我正在使用React-Native创建应用程序,并在Android设备上进行测试。在添加了react-native-camera模块之后,会出现以下错误:
org.gradle.api.tasks.TaskExecutionException:执行任务“:react-native-camera:compileDebugJavaWithJavac”失败。
在“Build->Run Tasks”(Android Studio)中。
关于Java编译器,大约有20-30个错误,全部显示如下:error:包android.support.annotation不存在
,error:包android.support.v4.util不存在
,error:包android.support.media不存在
等。
或者是error:找不到符号类SparseArrayCompat
,error:包Pools不存在
,error:找不到符号变量ExifInterface
,当检查错误文件时,这与import android.support.v4.util.ArrayMap;
-import类型的语句有关。
我的android/build.gradle文件:

targetSdkVersion = 27

}
我的尝试解决方案:
- 我将android-support-v4.jar文件添加到./libs文件夹中。
- 我在依赖项中添加了“google()”或maven链接。
- 我尝试更改minSdkVersion,compileVersion等,但没有帮助,但我猜这可能是主要问题所在。
- 重建项目也没有起作用。
- 将项目迁移到Android X。
我的SDK版本:28
Gradle版本:4.10.1
classpath 'com.android.tools.build:gradle:3.3.1'(将Gradle版本降级为3.1.0也无效)。
