## v2 to v3 upgrade

If you are upgrading from v2 to v3, check the guide out: https://github.com/react-native-community/react-native-device-info/wiki/V2-to-V3-Migration-Guide

## v3 to v4 upgrade

For those upgrading to v4, follow the v2 to v3 guide first, then follow this: https://github.com/react-native-community/react-native-device-info/wiki/V3-to-V4-Migration-Guide

## 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

## AndroidX Support

This module defaults to AndroidX you should configure your library versions similar to this in your `android/build.gradle` file's "ext" block

<details>
    <summary>Android</summary>

```gradle
...
  ext {
    // dependency versions

    We have 3 options for deviceId:
    //Option 1 (latest):
    firebaseIidVersion = "19.0.1" // default: "19.0.1"
    //Option 2 (legacy GooglePlay dependency but using AndroidX):
    googlePlayServicesIidVersion = "17.0.0" // default: "17.0.0" - AndroidX
    //Option 3 (legacy GooglePlay dependency before AndroidX):
    googlePlayServicesIidVersion = "16.0.1"


    //include as needed:
    compileSdkVersion = "28" // default: 28 (28 is required for AndroidX)
    targetSdkVersion = "28" // default: 28 (28 is required for AndroidX)
    supportLibVersion = '1.0.2' // Use '28.0.0' or don't specify for old libraries, '1.0.2' or similar for AndroidX
    mediaCompatVersion = '1.0.1' // Do not specify if using old libraries, specify '1.0.1' or similar for androidx.media:media dependency
    supportV4Version = '1.0.0' // Do not specify if using old libraries, specify '1.0.0' or similar for androidx.legacy:legacy-support-v4 dependency
  }
...
```

</details>

If you need non-AndroidX you will need to use the jetifier package in reverse mode, documentation available with that package.

## Linking (for React Native <= 0.59 only, React Native >= 0.60 skip this as auto-linking should work)

### 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
```

_For iOS users using Pods_
You still need to run `pod install` after running the above link command inside your `IOS` folder.

### Manual

<details>
    <summary>iOS (via CocoaPods) RN <= 59 </summary>

RN <= 59: [`Bug`](https://github.com/react-native-community/react-native-device-info/issues/748)

```
mv ios/Podfile .
react-native link react-native-device-info
mv Podfile ios
```

Do _not_ append `pod 'RNDeviceInfo', :path => '../node_modules/react-native-device-info'` to the Podfile

</details>

<details>
    <summary>iOS (via CocoaPods) RN >= 60</summary>

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

```ruby
pod 'React', :path => '../node_modules/react-native'

# Explicitly include Yoga if you are using RN >= 0.42.0
pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

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

# React-Native is not great about React double-including from the Podfile
post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end

    # It removes React & Yoga from the Pods project, as it is already included in the main project.
    targets_to_ignore = %w(React yoga)
    if targets_to_ignore.include? target.name
      target.remove_from_project
    end
  end
end
```

Then run `pod install`

    <summary>iOS (without CocoaPods)</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/ios`
- Add the file `RNDeviceInfo.xcodeproj`

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: "16.1.0" - pre-AndroidX, override for AndroidX
    compileSdkVersion = "<Your compile SDK version>" // default: 28
    targetSdkVersion = "<Your target SDK version>" // default: 28
  }
...
```

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

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

- in `android/settings.gradle`:

```diff
...
include ':app'
+ 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+

- in `MainApplication.java`:

```diff
+ import com.learnium.RNDeviceInfo.RNDeviceInfo;

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

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

    ......
  }
```

#### With older versions of React Native

- in `MainActivity.java`:

```diff
+ import com.learnium.RNDeviceInfo.RNDeviceInfo;

  public class MainActivity extends ReactActivity {
    ......

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

NOTE: If you faced with this error: `Could not resolve all files for configuration ':react-native-device-info:debugCompileClasspath'.`, in `build.gradle` put `google()` in the first line (according to https://stackoverflow.com/a/50748249)

- in `android/build.gradle`:

```diff
allprojects {
    repositories {
+       google()
        ...
    }
}
```

<details>
    <summary>Windows</summary>

- Open the solution in Visual Studio for your Windows apps
- right click your in the Explorer and click Add > Existing Project...
- Navigate to `./<app-name>/node_modules/react-native-device-info/windows/RNDeviceInfo` and add `RNDeviceInfo.csproj`
- this time right click on your React Native Windows app under your solutions directory and click Add > Reference...
- check the `RNDeviceInfo` you just added and press ok
- open up `MainReactNativeHost.cs` for your app and edit the file like so:

```diff
+ using RNDeviceInfo;
......
        protected override List<IReactPackage> Packages => new List<IReactPackage>
        {
            new MainReactPackage(),
+           new RNDeviceInfoPackage(),
        };
```

## Usage

```js
import DeviceInfo from 'react-native-device-info';

// or ES6+ destructured imports

import { getUniqueId, getManufacturer } from 'react-native-device-info';
```

## API

Note that many APIs are platform-specific. If there is no implementation for a platform, then the "default" return values you will receive are 'unknown' for string, '-1' for number, and 'false' for boolean. Arrays and Objects will be empty ('[]' and '{}' respectively).

Every API returns a Promise but also has a corresponding API with 'Sync' on the end that operates synchronously. For example, you may prefer to call 'isCameraPresentSync()' during your app bootstrap to avoid async calls during the first parts of app startup.

#### Notes

> - iOS: This is [`IDFV`](https://developer.apple.com/documentation/uikit/uidevice/1620059-identifierforvendor) or a random string if IDFV is unavaliable. Once UID is generated it is stored in iOS Keychain and NSUserDefaults. So it would stay the same even if you delete the app or reset IDFV. You can _carefully_ consider it a persistent, cross-install unique ID. It can be changed only in case someone manually override values in Keychain/NSUserDefaults or if Apple would change Keychain and NSUserDefaults implementations.
>   Beware: The IDFV is calculated using your bundle identifier and thus will be different in app extensions.
> - android: Prior to Oreo, this id ([ANDROID_ID](https://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID)) will always be the same once you set up your phone.

=======
## Native interoperatibily

If you need to check for device type from the native side, you can use the following:
```java
import com.learnium.resolver.DeviceTypeResolver

...
deviceTypeResolver = new DeviceTypeResolver(context);
...
//Check if the device is a Tablet:
if(deviceTypeResolver.isTablet){
  ...
}else{
  ...
}
```




## 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. See the example project included here for a sample.

If you're using a different library that conflicts with `com.google.android.gms:play-services-gcm`, and you are certain you know what you are doing such that you will avoid version conflicts, you can simply
ignore this dependency in your gradle file:

```groovy
 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>[ios] - [NetworkInfo] Descriptors query returned error: Error Domain=NSCocoaErrorDomain Code=4099
 “The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated.”</summary>

This is a system level log that may be turned off by executing:

  <summary>[ios] - Multiple versions of React when using CocoaPods
  "tries to require 'react-native' but there are several files providing this module"</summary>

### RN<=59 You may need to adjust your Podfile like this if you use Cocoapods and have undefined symbols or duplicate React definitions

```ruby
target 'yourTargetName' do
  # See http://facebook.github.io/react-native/docs/integration-with-existing-apps.html#configuring-cocoapods-dependencies
  pod 'React', :path => '../node_modules/react-native', :subspecs => [
    'Core',
    'CxxBridge', # Include this for RN >= 0.47
    'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
    'RCTText',
    'RCTNetwork',
    'RCTWebSocket', # Needed for debugging
    'RCTAnimation', # Needed for FlatList and animations running on native UI thread
    # Add any other subspecs you want to use in your project
  ]

  # Explicitly include Yoga if you are using RN >= 0.42.0
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

  # Third party deps podspec link - you may have multiple pods here, just an example
  pod 'RNDeviceInfo', path: '../node_modules/react-native-device-info'

end

# if you see errors about React duplicate definitions, this fixes it. The same works for yoga.
post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end
  end
end

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

`react-native-device-info` contains native code, and needs to be mocked. Jest Snapshot support may work though.

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

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

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

    <summary>[warnings] - I get too many warnings (battery state, etc)</summary>

Some of the APIs (like getBatteryState) will throw warnings in certain conditions like on tvOS or the iOS emulator. This won't be visible in production but even in development it may be irritating. It is useful to have the warnings because these devices return no state, and that can be surprising, leading to github support issues. The warnings is intended to educate you as a developer. If the warnings are troublesome you may try this in your code to suppress them:

```javascript
import { YellowBox } from 'react-native';
YellowBox.ignoreWarnings(['Battery state']);
```

## react-native-dom

As a courtesy to developers, this library was made compatible in v0.21.6 with [react-native-dom](https://github.com/vincentriemer/react-native-dom) and [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.
