 * You need to have the Google Services API downloaded in your SDK.
 * Be sure to give your app access to the Google Fitness API, see [this](https://developers.google.com/fit/android/get-api-key) and [this](https://github.com/2dvisio/cordova-plugin-googlefit#sdk-requirements-for-compiling-the-plugin).
 * If you are wondering what key your compiled app is using, you can type `keytool -list -printcert -jarfile yourapp.apk`.

+* If you haven't configured the APIs correctly, particularly the OAuth requirements, you are likely to get 'User cancelled the dialog' as an error message, particularly this can happen if you mismatch the signing certificate and SHA-1 fingerprint.
 * You can use the Google Fitness API even if the user doesn't have Google Fit installed, but there has to be some other fitness app putting data into the Fitness API otherwise your queries will always be empty. See the [the original documentation](https://developers.google.com/fit/overview).
 * If you are planning to use [health data types](https://developers.google.com/android/reference/com/google/android/gms/fitness/data/HealthDataTypes) in Google Fit, be aware that you are always able to read them, but if you want write access [you need to ask permission to Google](https://developers.google.com/fit/android/data-types#restricted_data_types)
 * This plugin is set to use the latest version of the Google Play Services API (`<framework src="com.google.android.gms:play-services-fitness:+" />`). This is done to likely guarantee the compatibility with other plugins using Google Play Services, but bear in mind that a) the plugin was tested until version 9.8.0 of the APIs and b) other plugins may be using a different version of the API. If you run into an issue, check the generated gradle file (build.gradle) under `dependencies` between `// SUB-PROJECT DEPENDENCIES START` and `// SUB-PROJECT DEPENDENCIES END` and make sure that all versions of the `com.google.android.gms:play-services-xxxx` are the same.
