Android App Version – A Comprehensive Guide

Developing an Android app is just the beginning of your journey. Once your app is live on the Google Play Store, it’s important to keep track of its version.

Knowing the current version of your Android app helps you in many ways, such as bug fixing, feature enhancements, and ensuring a smooth user experience. In this tutorial, we will explore different methods to get the Android app version programmatically.

Method 1: Using PackageManager

If you want to retrieve the Android app version programmatically in your code, you can utilize the PackageManager class provided by Android. The PackageManager class allows you to access essential information about installed applications on a device.

To get started, follow these steps:

  • Create a new instance of the PackageManager using the getPackageManager() method:
  • PackageManager packageManager = getPackageManager();
  • Create a PackageInfo object, which will contain all the information about your app:
  • String packageName = getPackageName();
    PackageInfo packageInfo = packageManager.getPackageInfo(packageName, 0);
  • Access the version name and code:
  • String versionName = packageInfo.versionName;
    int versionCode = packageInfo.versionCode;
  • Show or use the retrieved information as needed!

Method 2: Using Manifest File

If you don’t require the version information programmatically, you can easily find the Android app version directly in your project’s AndroidManifest.xml file. The versionName attribute inside the manifest tag holds the human-readable version name of your app:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.yourpackage.name"
    android:versionCode="1"
    android:versionName="1.0">

You can also find the versionCode attribute, which represents the internal integer value of your app’s version:

<manifest xmlns:android="http://schemas.name"
    android:versionCode="1"
    android:versionName="1.0">

Taking it Further

Congratulations! You’ve learned two different methods to get the Android app version. Now, you can utilize this information for various purposes such as displaying the current version to users or comparing it with a server-based latest version to prompt for updates.

Note: Remember to update your AndroidManifest.xml file whenever you release a new version of your app, and increment both the versionCode and versionName.

This is just one aspect of Android development. Explore more features and techniques available in Android documentation to enhance your app’s functionality and user experience!
