How to Get Android App Version Programmatically?

To programmatically retrieve the version information of an Android application, developers can utilize the PackageManager class along with context to access versionName and versionCode.

One efficient way to achieve this is by leveraging the AndroidManifest.xml file, which contains essential meta-data about the app, including version details. Within the AndroidManifest.xml file, versionName specifies the public version number shown to users, while versionCode is an integer value used internally by the system to manage versioning. In Kotlin, you can access these details using the PackageInfo class, which provides methods to extract versionName and versionCode information. Manifest permissions must be declared to access this data, ensuring smooth extraction of app version information programmatically.

Step 1: Import Package

Begin by importing the necessary packages such as PackageManager and PackageInfo, ensuring proper error handling with try-catch blocks.

Once you have successfully imported the required packages, the next step involves retrieving information about the app version. For this, you can utilize ProductFlavors to manage different configurations and functionalities for your app. Utilizing the PackageInfo class, you can access details about the package, including version code and version name. It is essential to handle potential exceptions during this process using try-catch blocks to prevent any runtime errors that may occur while fetching version information.

Step 2: Get Package Info

Retrieve the PackageInfo object by calling the getPackageInfo method from the PackageManager class, handling exceptions like NameNotFoundException appropriately.

When accessing the PackageInfo object, you can extract essential information from the app’s manifest file, providing details such as version number, package name, and permissions. Utilize the appInfo attribute within the PackageInfo object to obtain various metadata related to the application.

To print this information, you may construct a structured output using Log.d or simply display it in the console. Remember to handle any potential exceptions thrown during the process to ensure the stability and reliability of your application.

Step 3: Get Version Code and Name

Extract the versionCode and versionName parameters from the obtained PackageInfo object by accessing specific fields like BuildConfig.VERSION_NAME and BuildConfig.VERSION_CODE.

To further enhance version control in your Android application, you can utilize these extracted details to display the current version in your app settings or about section. Integrating Gradle properties to manage the version settings dynamically can streamline the development process. By defining version values in the Gradle file, you can easily update them across multiple modules of your project. Be sure to maintain consistent versioning practices to ensure smooth upgrades and compatibility with future releases.

Step 4: Display Version Information

Display the retrieved version information on the user interface elements like versionNameTextView and versionCodeTextView to showcase the app’s current version.

Updating the user interface components with the version details helps users to easily identify which version of the app they are using. By setting the versionNameTextView to display the app’s name and the versionCodeTextView to show the version code, the interface becomes more user-friendly and informative. This visual representation not only enhances user experience but also adds a professional touch to the app. It is essential to keep these components easily accessible and clearly visible for users to stay informed about the app’s current version.
