List of Installed Apps on Android Device

Here is an easy way to get a list of installed apps on Android phone / tablet. 

PackageManager packManager = null;
ArrayList<ApplicationInfo> installedAppsList = new ArrayList<>();

try {

    packManager = context.getPackageManager();

    if (packManager != null) {
        
        installedAppsList = packManager .getInstalledApplications(0);
    }
} catch (Exception ex) {

       ex.printStackTrace();

}

Cheers!
