# Mobile Configuration



If your Meteor application targets mobile platforms such as iOS or
Android, you can configure your app's metadata and build process
in a special top-level file called
`mobile-config.js` which is *not* included in your application and is used only
for this configuration.

The code snippet below is an example `mobile-config.js` file. The rest of this
section will explain the specific API commands in greater detail.

```js
// This section sets up some basic app metadata, the entire section is optional.
App.info({
  id: 'com.example.matt.uber',
  name: 'über',
  description: 'Get über power in one button click',
  author: 'Matt Development Group',
  email: 'contact@example.com',
  website: 'http://example.com'
});

// Set up resources such as icons and launch screens.
App.icons({
  'iphone_2x': 'icons/icon-60@2x.png',
  'iphone_3x': 'icons/icon-60@3x.png',
  // More screen sizes and platforms...
});

// Before Meteor 2.6 we had to pass device specific splash screens for iOS, but this behavior was dropped in favor of story board images.
App.launchScreens({
    // iOS
    // For most cases you will only need to use the 'ios_universal' and 'ios_universal_3x'.
    'ios_universal': { src: 'splash/Default@2x.png', srcDarkMode: 'splash/Default@2x~dark.png' }, // (2732x2732) - All @2x devices, if device/mode specific is not declared
    'ios_universal_3x': 'splash/Default@3x.png', // (2208x2208) - All @3x devices, if device/mode specific is not declared

    // If you still want to use a universal splash, but want to fine-tune for the device mode (landscape, portrait), then use the following keys:
    'Default@2x~universal~comany': 'splash/Default@2x~universal~comany.png', // (1278x2732) - All @2x devices in portrait mode.
    'Default@2x~universal~comcom': 'splash/Default@2x~universal~comcom.png', // (1334x750) - All @2x devices in landscape (narrow) mode.
    'Default@3x~universal~anycom': 'splash/Default@3x~universal~anycom.png', // (2208x1242) - All @3x devices in landscape (wide) mode.
    'Default@3x~universal~comany': 'splash/Default@3x~universal~comany.png', // (1242x2208) - All @3x devices in portrait mode.

    // However, if you need to fine tune the splash screens for the device idiom (iPhone, iPad, etc).
    'Default@2x~iphone~anyany': 'splash/Default@2xiphoneanyany.png', // (1334x1334) - iPhone SE/6s/7/8/XR
    'Default@2x~iphone~comany': 'splash/Default@2xiphonecomany.png', // (750x1334) - iPhone SE/6s/7/8/XR - portrait mode
    'Default@2x~iphone~comcom': 'splash/Default@2xiphonecomcom.png', // (1334x750) - iPhone SE/6s/7/8/XR - landscape (narrow) mode
    'Default@3x~iphone~anyany': 'Default@3xiphoneanyany.png', // (2208x2208) - iPhone 6s Plus/7 Plus/8 Plus/X/XS/XS Max
    'Default@3x~iphone~anycom': { src: 'splash/Default@3xiphoneanycom.png', srcDarkMode: 'splash/Default@3xiphoneanycom~dark.png' }, // (2208x1242) - iPhone 6s Plus/7 Plus/8 Plus/X/XS/XS Max - landscape (wide) mode
    'Default@3x~iphone~comany': 'Default@3xiphonecomany.png', // (1242x2208) - iPhone 6s Plus/7 Plus/8 Plus/X/XS/XS Max - portrait mode
    'Default@2x~ipad~anyany': 'Default@2xipadanyany.png', // (2732x2732) - iPad Pro 12.9"/11"/10.5"/9.7"/7.9"
    'Default@2x~ipad~comany': 'Default@2xipadcomany.png', // (1278x2732) - iPad Pro 12.9"/11"/10.5"/9.7"/7.9" - portrait mode

    // Android
    'android_universal': 'splash/android_universal.png', // (320x480)
});

// Set PhoneGap/Cordova preferences.
App.setPreference('BackgroundColor', '#000000ff');
App.setPreference('HideKeyboardFormAccessoryBar', true);
App.setPreference('Orientation', 'default');
App.setPreference('Orientation', 'all', 'ios');

// Pass preferences for a particular PhoneGap/Cordova plugin.
App.configurePlugin('com.phonegap.plugins.facebookconnect', {
  APP_ID: '1234567890',
  API_KEY: 'supersecretapikey'
});

// Add custom tags for a particular PhoneGap/Cordova plugin to the end of the
// generated config.xml. 'Universal Links' is shown as an example here.
App.appendToConfig(`
  <universal-links>
    <host name="localhost:3000" />
  </universal-links>
`);
```

<ApiBox name="App.info" />
<ApiBox name="App.setPreference" />
<ApiBox name="App.accessRule" />

For example this Cordova whitelist syntax:

```xml
<access origin="https://www.google-analytics.com" />
<allow-navigation href="https://example.com" />
```

is equivalent to:

```js
App.accessRule('https://www.google-analytics.com');
App.accessRule('https://example.com', { type: 'navigation' });
```

<ApiBox name="App.configurePlugin" />

> Note: When using `App.configurePlugin` to re-configure a plugin which has been previously configured, the changes may not be reflected without manually clearing the existing Cordova build.  To clear the existing Cordova build, remove the `.meteor/local/cordova-build` directory and re-build the application using either `meteor run` or `meteor build`.

<ApiBox name="App.icons" />
<ApiBox name="App.launchScreens" />
<ApiBox name="App.appendToConfig" />
<ApiBox name="App.addResourceFile" />

> Note: The resource file is copied in two steps : from the **src** of your meteor project to the root of the cordova project, then to the **target**
