react-native-sensor-manager

react-native-sensor-manager
============================

Wrapper for react-native. Accelerometer, Gyroscope, Magnetometer, Step Counter, Thermometer are supported for now.

Add it to your project
-------------------------

$ npm i react-native-sensor-manager --save

$3

rnpm link

$3

Make alterations to the following files:

* android/settings.gradle

``gradle
...
include ':react-native-sensor-manager'
project(':react-native-sensor-manager').projectDir = new File(settingsDir, '../node_modules/react-native-sensor-manager/android')
`

* android/app/build.gradle

`gradle
...
dependencies {
...
compile project(':react-native-sensor-manager')
}
`

* register module (in MainActivity.java)

* For react-native below 0.19.0 (use cat ./node_modules/react-native/package.json | grep version)

`java
import com.sensormanager.SensorManagerPackage; // <------ add package

public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {

......

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mReactRootView = new ReactRootView(this);

mReactInstanceManager = ReactInstanceManager.builder()
.setApplication(getApplication())
.setBundleAssetName("index.android.bundle")
.setJSMainModuleName("index.android")
.addPackage(new MainReactPackage())
.addPackage(new SensorManagerPackage()) // <------- add package
.setUseDeveloperSupport(BuildConfig.DEBUG)
.setInitialLifecycleState(LifecycleState.RESUMED)
.build();

mReactRootView.startReactApplication(mReactInstanceManager, "ExampleRN", null);

setContentView(mReactRootView);
}

......

}
`

* For react-native 0.19.0 and higher
`java
import com.sensormanager.SensorManagerPackage; // <------ add package

public class MainActivity extends ReactActivity {
// ...
@Override
protected List getPackages() {
return Arrays.asList(
new MainReactPackage(), // <---- add comma
new SensorManagerPackage() // <---------- add package
);
}
`
