Java Code to check if Twitter app is installed on Android device

If you have created an Android Application with Twitter App integration, i.e. say the user can send tweets of highest scores earned while playing your game app. Then before sending a tweet out its better to detect if the Twitter application is being present on the device.

To check if the Twitter app is installed we first need to know what is the package name of the app, you can get it to form PlayStore link for Twitter for Android.

Package name : com.twitter.android

ApplicationInfo class is used to get information about an app that is being installed on the device. This information is collect from the AndroidManifest.xml <application> tag.

getApplicationInfo() method will retrieve all the information for the package/application name passed. It returns the ApplicationInfo object that contains details about the package.

⚠️ This package throws PackageManager.NameNotFoundException

public boolean isTwitterInstalled() {


        try {

            boolean twitterInstalled = false;
            PackageInfo packageInfo = getPackageManager().getPackageInfo("com.twitter.android", 0);
            String getPackageName = packageInfo.toString();

            if (getPackageName.equals("com.twitter.android")) {

                Toast.makeText(this, "Twitter App is installed on device!", Toast.LENGTH_LONG).show();
                twitterInstalled = true;
            }
        } catch (PackageManager.NameNotFoundException e) {

            Toast.makeText(this, "Twitter App not found on device!", Toast.LENGTH_LONG).show();
       
        }
