## Installation

Using npm:

```shell
npm install --save react-native-device-info
```

or using yarn:

```shell
yarn add react-native-device-info
```

> ⚠️ If you are on React Native > 0.47, you must use version 0.11.0 of this library or higher

## Linking

### Automatic

```shell
react-native link react-native-device-info
```

(or using [`rnpm`](https://github.com/rnpm/rnpm) for versions of React Native < 0.27)

```shell
rnpm link react-native-device-info
```

### Manual

<details>
    <summary>iOS (via Cocoa Pods)</summary>

Add the following line to your build targets in your `Podfile`

`pod 'RNDeviceInfo', :path => '../node_modules/react-native-device-info'`

Then run `pod install`

</details>

<details>
    <summary>iOS (without Cocoa Pods)</summary>

In XCode, in the project navigator:

* Right click _Libraries_
* Add Files to _[your project's name]_
* Go to `node_modules/react-native-device-info`
* Add the `.xcodeproj` file

In XCode, in the project navigator, select your project.

* Add the `libRNDeviceInfo.a` from the _deviceinfo_ project to your project's _Build Phases ➜ Link Binary With Libraries_
* Click `.xcodeproj` file you added before in the project navigator and go the _Build Settings_ tab. Make sure _All_ is toggled on (instead of _Basic_).
* Look for _Header Search Paths_ and make sure it contains both `$(SRCROOT)/../react-native/React` and `$(SRCROOT)/../../React`
* Mark both as recursive (should be OK by default).

Run your project (Cmd+R)

<details>
    <summary>Android</summary>

* **_optional_** in `android/build.gradle`:

```gradle
...
  ext {
    // dependency versions
    googlePlayServicesVersion = "<Your play services version>" // default: "+"
    compileSdkVersion = "<Your compile SDK version>" // default: 23
    buildToolsVersion = "<Your build tools version>" // default: "25.0.2"
    targetSdkVersion = "<Your target SDK version>" // default: 22
  }
...
```

* in `android/app/build.gradle`:

```diff
dependencies {
    ...
    compile "com.facebook.react:react-native:+"  // From node_modules
+   compile project(':react-native-device-info')
}
```

* in `android/settings.gradle`:

```diff
...

+ include ':react-native-device-info'
+ project(':react-native-device-info').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-device-info/android')
```

#### With React Native 0.29+

+ import com.learnium.RNDeviceInfo.RNDeviceInfo;

  public class MainApplication extends Application implements ReactApplication {
    //......

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
+         new RNDeviceInfo(),

      );
    }

    ......
  }
```

#### With older versions of React Native:

The font scale is the ratio of the current system font to the "normal" font size, so if normal text is 10pt and the system font is currently 15pt, the font scale would be 1.5
This can be used to determine if accessability settings has been changed for the device; you may want to re-layout certain views if the font scale is significantly larger ( > 2.0 )

>
> Return the primary shared/external storage directory.
>
> Note: don't be confused by the word "external" here. This directory can better be thought as
> media/shared storage. It is a filesystem that can hold a relatively large amount of data and
> that is shared across all applications (does not enforce permissions). Traditionally this is
> an SD card, but it may also be implemented as built-in storage in a device that is distinct
> from the protected internal storage and can be mounted as a filesystem on a computer.

## Troubleshooting

When installing or using `react-native-device-info`, you may encounter the following problems:

<details>
  <summary>[android] - Unable to merge dex / Multiple dex files / Problems with `com.google.android.gms`</summary>

`react-native-device-info` uses `com.google.android.gms:play-services-gcm` to provide [getInstance()][#getinstance].
This can lead to conflicts when building the Android application.

If you're using a different version of `com.google.android.gms:play-services-gcm` in your app, you can define the
`googlePlayServicesVersion` gradle variable in your `build.gradle` file to tell `react-native-device-info` what version
it should require.

If you're using a different library that conflicts with `com.google.android.gms:play-services-gcm`, you can simply
ignore this dependency in your gradle file:

```
 compile(project(':react-native-device-info')) {
    exclude group: 'com.google.android.gms'
}
```

</details>

<details>
  <summary>[ios] - ld: library not found for -lRNDeviceInfo-tvOS</summary>

Seems to be a bug caused by `react-native link`. You can manually delete `libRNDeviceInfo-tvOS.a` in `Xcode -> [Your iOS build target] -> Build Phrases -> Link Binary with Libraries`.

</details>

<details>
  <summary>[tests] - Cannot run my test suite when using this library</summary>

`react-native-device-info` contains native code, and needs to be mocked.

Here's how to do it with jest for example:

```
// in your package.json:
"jest": {
  "setupFiles": [
    "./testenv.js"
  ],


// testenv.js:
jest.mock('react-native-device-info', () => {
  return {
    getModel: jest.fn(),
  };
});
```

</details>

## Release Notes

See the [CHANGELOG.md](https://github.com/rebeccahughes/react-native-device-info/blob/master/CHANGELOG.md).

## react-native-web

As a courtesy to developers, this library was made compatible in v0.17.0 with [react-native-web](https://github.com/necolas/react-native-web) by providing an empty polyfill in order to avoid breaking builds.

Only [getUserAgent()](#getuseragent) will return a correct value. All other API methods will return an "empty" value of its documented return type: `0` for numbers, `''` for strings, `false` for booleans.
