What parameters in the AndroidManifest.xml file need to be properly configured for inter-application data exchange?

To implement inter-application data exchange in Android via AndroidManifest.xml, it is important to correctly configure the following parameters:

• <intent-filter>: Defines which intents the component (Activity, Service, BroadcastReceiver) can receive. For data exchange, you need to specify the appropriate action, category, and data so that other applications can find and invoke your component.

• android:exported: This attribute indicates whether the component is available for invocation from other applications. For inter-application interaction, it should be set to true.

• <provider>: If a ContentProvider is used for data exchange, it should be declared in the manifest with a unique android:authorities and set android:exported="true".

• permissions: If necessary, specify permissions (android:permission) to restrict access to components or providers.

Example for an Activity accessible from other applications:

<activity android:name=".ShareActivity" android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.SEND" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="text/plain" />
    </intent-filter>
</activity>

Thus, correct configuration of intent filters, the exported attribute, and permissions if necessary, are key to successful inter-application data exchange.
