react-native-sensors Error: Native modules for sensors not available. Did react-native link run successfully?

Question

Thanks for any help, getting error message "Error: Native modules for sensors not available. Did react-native link run successfully?" when running npx react-native start

npx react-native run-android gives this error: > Task :app:processDebugManifest FAILED right after installing react-native-sensors.

Install procedure:

npx react-native init proj8

cd proj8

npm install react-native-sensors --save

npx react-native link react-native-sensors

The last command reported successful but when I went through the manual Android procedure some parts were not done as follows:

import com.sensors.RNSensorsPackage;

was in android/app/src/main/java/[...]/MainApplication.java

new RNSensorsPackage() was not there, I added as follows:

@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')

were both there in 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

I had to add implementation project(':react-native-sensors')

I don't think my code matters yet but 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
}

package.json:

{
  "name": "proj8",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "android": "react-native run-android",
    "ios": "react-native run-ios",

  }
}

Could you create a repo with your changes so that one can check it out? — Daniel Schmidt, Oct 22 '20 at 15:53

I encountered the same problem. This occurs because react-native-sensors has a minsdk version is 17 and react-native's default minsdk version is 16 Its quite easy to solve.

Just go to android/build.gradle
Change minSdkVersion to anything above 17

Before

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

After

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