Configuring Android Applications

Android applications require a robust configuration system to manage various settings, permissions, and data storage. This article covers different methods for configuring an Android application, including using the AndroidManifest.xml file, resource files, and external configuration files. Additionally, it explores managing app configurations using Microsoft Intune and Miradore.

Configuring AndroidManifest.xml

The AndroidManifest.xml file is the core configuration file for any Android application. It manages permissions, device features, and other essential settings.

Permissions

Permissions define what the app can do on the device, such as accessing the internet, camera, or location. They are declared in the AndroidManifest.xml file within the <manifest> tag. For example, to add network permissions, include the following code:

xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<!-- Other permissions and activities -->

Package ID and App Name

The package ID (also known as the application ID) is unique to each app and is defined in the build.gradle file:

groovy
defaultConfig {
applicationId "com.mycompany.myapp"
}

Change the app name by modifying the app_name string in the strings.xml file:

xml
MyApp

Deeplinks and URL Schemes

Deeplinks allow your app to handle custom URLs, making it easier for users to interact with your app directly from other apps or web pages. To enable deeplinking, configure Android App Links by adding the following code to your AndroidManifest.xml file:

xml

Set up the URL scheme in the strings.xml file:

xml
com.capacitorjs.myapp

Using Resource Files

Resource files are a powerful way to manage configuration data in Android applications. These files are stored in the res directory and can be accessed using the Resources class.

Creating Resource Files

To create a resource file, add a new XML file to the res/values directory. For example, create a file named configuration.xml with the following content:

xml


dev
750
true

Accessing Resource Values

Access these values at runtime using the Resources class:

java
Resources res = getResources();
String environment = res.getString(R.string.environment);
int lookupTimeout = res.getInteger(R.integer.lookup_timeout);
boolean useCache = res.getBoolean(R.bool.use_cache);

Overriding Resource Values

Override resource values for different screen sizes, OS versions, or environments. For example, create a separate XML file for API Level 11 and above:

xml



prod
1000
false

Using External Configuration Files

Sometimes, storing configuration data in external files is more convenient. This approach is particularly useful for sensitive data like API keys or passwords.

Using .properties Files

One common method is using a .properties file. Create a config.properties file in the res/raw directory:

properties
api_url=http://url.to.api/v1/
api_key=123456

Access these values using the Properties class:

java
Properties config = new Properties();
InputStream inputStream = getResources().openRawResource(R.raw.config);
config.load(inputStream);
String apiUrl = config.getProperty("api_url");
String apiKey = config.getProperty("api_key");

Using SharedPreferences

Another approach is using SharedPreferences. This method is suitable for user-modifiable settings and storing sensitive data securely:

java
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(context);
sp.edit().putString("api_url", "http://url.to.api/v1/").commit();
sp.edit().putString("api_key", "123456").commit();

Retrieve these values as follows:

java
String apiUrl = sp.getString("api_url", "");
String apiKey = sp.getString("api_key", "");

Managing App Configurations with Microsoft Intune

Microsoft Intune provides a robust way to manage app configurations for Android Enterprise devices.

Creating an App Configuration Policy

1. Sign in to the Microsoft Intune admin center.
2. Choose Apps > App configuration policies > Add > Managed devices.
3. Set the Basics page details:
   • Name: The name of the profile that appears in the portal.
   • Description: The description of the profile that appears in the portal.
   • Device enrollment type: Set to Managed devices.
4. Select Android Enterprise as the Platform.
5. Click Select app next to Targeted app and choose the managed app to associate with the configuration policy.
6. Click Next to display the Settings page.
7. Click Add to display the Add permissions pane and select permissions to override.
8. Set Permission state for each permission:
   • Prompt: Prompt the user to accept or deny.
   • Auto grant: Automatically approve without notifying the user.
   • Auto deny: Automatically deny without notifying the user.
9. If supported by your app, select Configuration settings format:
   • Use configuration designer or enter JSON data.
10. Enable Connected apps if needed:
    • This setting only works for personally owned work profile and corporate-owned work profile devices.
11. Click Save to assign the policy.

Preconfiguring Permissions

Preconfigure app permissions to access Android device features. By default, Android apps that require device permissions prompt users to accept or deny permissions. For example, an app using the device's microphone will prompt users to grant permission:

1. In the Microsoft Intune admin center, select Apps > App configuration policies > Add > Managed devices.
2. Add properties:
   • Name: Enter a descriptive name for the policy.
   • Description: Enter a description for the profile (optional but recommended).
   • Device enrollment type: Set to Managed devices.
   • Platform: Select Android Enterprise.
3. Select Profile Type:
   • Select Targeted App and choose the app you want to associate with the configuration policy.
4. Select Permissions > Add from the list and select available app permissions > OK.
5. Select an option for each permission:
   • Prompt: Prompt the user to accept or deny.
   • Auto grant: Automatically approve without notifying the user.
   • Auto deny: Automatically deny without notifying the user.
6. Assign the app configuration policy:
   • Select Assignment > Select groups and choose user groups to assign > Select.
   • Choose Save to assign the policy.

Using Miradore for Managed Configurations

Miradore provides another method for managing app configurations, specifically for managed Google Play applications.

Requirements

• Managed Google Play apps: Only supported for managed Google Play apps.
• Device Management: Supported for devices managed with Android Enterprise’s Fully Managed Device mode or Work Profile mode.

Steps to Define Managed App Configurations

1. Navigate to Management > Applications to see available applications.
2. Open up any of the managed Google Play applications.
3. Go to the Configurations tab of the Application page and click Select configuration > Add configuration.
4. Enter a name for the managed app configuration into the text box.
5. See the list of configuration keys supported by the app and hover over the info icon to learn more about each key.
6. Click the plus button from the rightmost end of each row to define a configuration key.
7. Refer to application developer’s documentation for more information about configuration keys.

Examples of Configuring Apps

• Configuring Google Chrome on Android
• Configuring Exchange for Outlook on Android
• Configuring Exchange for Gmail on Android

Configuring an Android application involves several steps, including managing permissions, setting up resource files, using external configuration files, and managing app configurations with tools like Microsoft Intune and Miradore. Each method has its own advantages and is suited for different scenarios. By understanding these configurations, developers can create more robust and customizable applications that meet the needs of various users and environments.
