感谢您的帮助，收到错误消息“错误：传感器的本机模块不可用。react-native 链接是否成功运行？” 运行 npx react-native start 时

npx react-native run-android 给出此错误：> 安装 react-native-sensors 后任务：app:processDebugManifest FAILED。

安装程序：

npx react-native init proj8

cd proj8

npm install react-native-sensors --save

npx react-native 链接 react-native-sensors

最后一个命令报告成功，但是当我通过手动 Android 程序时，某些部分未完成，如下所示：

import com.sensors.RNSensorsPackage;

在 android/app/src/main/java/[...]/MainApplication.java

new RNSensorsPackage() 不在那里，我添加如下：

@Override
       protected List<ReactPackage> getPackages() {
       @SuppressWarnings("UnnecessaryLocalVariable")
       List<ReactPackage> packages = new PackageList(this).getPackages();
       // Packages that cannot be autolinked yet can be added manually here, for example:
       // packages.add(new MyReactNativePackage());
       packages.add(new RNSensorsPackage());
       return packages;
}

include ':react-native-sensors'
project(':react-native-sensors').projectDir = new File(rootProject.projectDir,  '../node_modules/react-native-sensors/android')

都在 android/settings.gradle

dependencies {
    implementation project(':react-native-sensors')
    implementation fileTree(dir: "libs", include: ["*.jar"])
    //noinspection GradleDynamicVersion
    implementation "com.facebook.react:react-native:+"  // From node_modules

我必须添加实施项目（'：react-native-sensors'）

我认为我的代码并不重要，但 App.js：

import React, {useState, useEffect, useRef} from 'react';
import { StyleSheet,ScrollView,SafeAreaView,Platform, View,Text } from 'react-native';

export default function App() {
    var Rndr = 
        <Text>asdf</Text>
    return Rndr
}

包.json：

我遇到了同样的问题。出现这种情况是因为react-native-sensors的 minsdk 版本是 17，而 react-native 的默认 minsdk 版本是 16，这很容易解决。

  1. 只需转到android/build.gradle
  2. 将 minSdkVersion更改为 17 以上的任何值

前

 ext {
    buildToolsVersion = "29.0.2"
    minSdkVersion = 16
    compileSdkVersion = 29
    targetSdkVersion = 29
}

后

 ext {
    buildToolsVersion = "29.0.2"
    minSdkVersion = 19
    compileSdkVersion = 29
    targetSdkVersion = 29
}
