APP UPDATE AND MODERNIZATION
GUIDE
Step 1: Opening the Code in Android Studio
(For Android Apps)
1. Install Android Studio:
● Download and install the latest version of Android Studio from here.
● Follow the installation instructions specific to your operating system (Windows, macOS,
or Linux).
2. Open Your Project in Android Studio:
● Launch Android Studio.
● Click File > Open and navigate to your app’s root folder (the folder that contains files
like build.gradle or app folder).
● Select the folder and click OK. Android Studio will automatically import your project.
3. Sync the Project:
● Once your project opens, Android Studio will attempt to sync all dependencies.
● If you see a message like “Gradle sync failed” or “dependencies not found,” you may
need to update your Gradle version or the dependencies in the build.gradle file.

,4. Explore the Code:
● In the left-hand Project Explorer pane, you’ll see the structure of your app. Key folders
include:
○ app > java: Contains the main code.
○ app > res: Contains resources like layouts, images, and strings.
○ app > manifests: Contains the AndroidManifest.xml file, which describes
essential app information.
Step 2: Opening the Code in Xcode (For iOS Apps)
1. Install Xcode:
● Download and install the latest version of Xcode from the Mac App Store here.
2. Open Your Project in Xcode:
● Launch Xcode.
● Click File > Open and navigate to your app’s root folder (the folder containing the
.xcodeproj or .xcworkspace file).
● Select the file and click Open. Xcode will load your project.
3. Explore the Code:
● In Xcode, the left-hand Navigator panel displays your project’s structure:
○ Main.storyboard or SwiftUI files: These files define the UI.
○ ViewController.swift: This is where your main logic might reside.

, ○ Assets.xcassets: Contains images and icons.
4. Resolve Errors:
● If Xcode flags any issues, such as deprecated methods or outdated libraries, you can
click on the warnings or errors, and Xcode will suggest fixes or let you search for the
latest versions of the frameworks.
Next Steps: Updating Dependencies
Once the project is open, the next logical step is to update the dependencies (libraries or
frameworks the app uses).
Android (Gradle Dependencies):
1. Open the build.gradle file in Android Studio.
2. Find the lines that define your app’s libraries (e.g., implementation
'com.android.support:appcompat-v7:28.0.0').
3. Go to Maven Repository or check the documentation for each library to find the latest
version, then replace the old version in the build.gradle file.
4. After updating, click Sync Now when prompted by Android Studio.
iOS (CocoaPods or Swift Package Manager):
1. If your project uses CocoaPods:
○ Open the Podfile in Xcode or a text editor.
○ Update the version numbers of the libraries.
○ Run pod install in the terminal.

, 2. For Swift Package Manager, go to File > Swift Packages > Update to Latest
Package Versions.
