How to Implement Custom Actions for an App Post-Installation

How can I implement a custom action in my app that triggers immediately after the installation is complete?

// Sample code for triggering actions after installation
if (isAppInstalled()) {
    performCustomAction();
}

To implement custom actions that occur immediately after an app installation, developers often utilize methods provided by the operating system or app management tools. Depending on the platform (iOS, Android, etc.), there are various approaches to ensure your custom logic is invoked seamlessly after installation.

// Android example: checking if first launch to perform custom action
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        SharedPreferences prefs = getSharedPreferences("MyAppPrefs", MODE_PRIVATE);
        if (prefs.getBoolean("isFirstRun", true)) {
            performCustomAction(); // Call your custom action
            prefs.edit().putBoolean("isFirstRun", false).apply();
        }
    }
}

Causes

• The lack of a clear app lifecycle management process can prevent the execution of custom actions post-installation.
• Inadequate permissions set in the application manifest may cause failures in executing code.

Solutions

• Leverage the app's entry point to check if the installation is complete, such as using a listener in the onCreate method for Android apps.
• For iOS apps, consider implementing the `didFinishLaunchingWithOptions` method to check any flags indicating the first launch.
• Utilize background services or notifications to carry out your custom actions post-installation when the user first opens the app.

Mistake: Not handling user permissions correctly can prevent the app from executing actions such as accessing the internet or local storage.

Solution: Ensure your app requests the necessary permissions at runtime and gracefully handle any denied permissions.

Mistake: Assuming that all devices will behave the same way can lead to inconsistencies in action execution.

Solution: Test on multiple devices and operating system versions to ensure compatibility.
