React Native Background Geolocation Example

Intro

This is an example app of react-native-mauron85-background-geolocation component.

Binary build

There is apk in dist folder.

How to build

In cloned directory:

1. npm install

Also read setup instructions.

Android

Check android lib versions:

Name	Version
Google Play Services	>=30
Google Repository	>=28

Generate your SHA1 key to restrict usage to your app only (optional):

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Go to Google API Console and select your project, or create new one:

In Overview -> Google Maps API -> Google Maps Android API -> Check if it's enabled. If not, click button Enable! Create a new key by clicking on Create credentials -> API Key -> Android Key, enter the name of the API key and your SHA1 key, generated before, and create it.

Add Google Maps Android API Key in android/app/src/main/res/values/strings.xml:

<resources>
    ...
    <string name="google_api_key">{{Your Google maps API Key Here}}</string>
</resources>

Module react-native-maps v0.8.2 requires Google Play Services library version 9.4.0, we need to change node_modules/react-native-mauron85-background-geolocation/android/lib/build.gradle

dependencies {
    ...
    compile 'com.google.android.gms:play-services-location:9.4.0'
    ...
}
