I think using try catch pattern is not very well for performance  I advice to use this   public static boolean appInstalledOrNot Context context  String uri        PackageManager pm   context getPackageManager        List lt PackageInfo gt  packageInfoList   pm getInstalledPackages PackageManager GET ACTIVITIES       if  packageInfoList    null            for  PackageInfo packageInfo   packageInfoList                String packageName   packageInfo packageName              if  packageName    null  amp  amp  packageName equals uri                     return true                                    return false

The above code didn t work for me  The following approach worked   Create an Intent object with appropriate info and then check if the Intent is callable or not using the following function   private boolean isCallable Intent intent              List lt ResolveInfo gt  list   getPackageManager   queryIntentActivities intent             PackageManager MATCH DEFAULT ONLY             return list size    gt  0

A cool answer to other problems  If you do not want to differentiate  com myapp debug  and  com myapp release  for example     public static boolean isAppInstalled final Context context  final String packageName        final List lt ApplicationInfo gt  appsInfo   context getPackageManager   getInstalledApplications 0       for  final ApplicationInfo appInfo   appsInfo            if  appInfo packageName contains packageName   return true            return false

You can do it using Kotlin extensions   fun Context getInstalledPackages    List lt String gt        val packagesList   mutableListOf lt String gt        packageManager getInstalledPackages 0  forEach           if   it applicationInfo sourceDir startsWith  quot  data app  quot    amp  amp  it versionName    null              packagesList add it packageName            return packagesList    fun Context isInDevice packageName  String   Boolean       return getInstalledPackages   contains packageName

Try with this   public class MainActivity extends AppCompatActivity        Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState               Add respective layout         setContentView R layout main activity               Use package name which we want to check         boolean isAppInstalled   appInstalledOrNot  com check application               if isAppInstalled                  This intent will help you to launch if the package is already installed             Intent LaunchIntent   getPackageManager                    getLaunchIntentForPackage  com check application                startActivity LaunchIntent                Log i  Application is already installed                      else                  Do whatever we want to do if application not installed                For example  Redirect to play store              Log i  Application is not currently installed                          private boolean appInstalledOrNot String uri            PackageManager pm   getPackageManager            try               pm getPackageInfo uri  PackageManager GET ACTIVITIES               return true            catch  PackageManager NameNotFoundException e                       return false

If you know the package name  then this works without using a try-catch block or iterating through a bunch of packages   public static boolean isPackageInstalled Context context  String packageName        final PackageManager packageManager   context getPackageManager        Intent intent   packageManager getLaunchIntentForPackage packageName       if  intent    null            return false            List lt ResolveInfo gt  list   packageManager queryIntentActivities intent  PackageManager MATCH DEFAULT ONLY       return  list isEmpty

So nicer with Kotlin suger     private fun isSomePackageInstalled context  Context  packageName  String   Boolean        val packageManager   context packageManager      return runCatching   packageManager getPackageInfo packageName  0    isSuccess

Check App is installed or not in Android by using kotlin    Creating kotlin extension   fun PackageManager isAppInstalled packageName  String   Boolean   try           getApplicationInfo packageName  PackageManager GET META DATA          true       catch  e  Exception            false         Now  can check if app is install or not  if  packageManager isAppInstalled  AppPackageName             App is installed  else         App is not installed

All the answers only check certain app is installed or not  But  as we all know an app can be installed but disabled by the user  unusable   Therefore  this solution checks for both  i e  installed AND enabled apps   public static boolean isPackageInstalled String packageName  PackageManager packageManager         try             return packageManager getApplicationInfo packageName  0  enabled              catch  PackageManager NameNotFoundException e              return false             Call the method isPackageInstalled     boolean isAppInstalled   isPackageInstalled  com android app    this getPackageManager       Now  use the boolean variable isAppInstalled and do whatever you want   if isAppInstalled            do whatever you want

Try this  This code is used to check weather your application with package name is installed or not if not then it will open playstore link of your app otherwise your installed app  String your apppackagename  quot com app testing quot       PackageManager packageManager   getPackageManager        ApplicationInfo applicationInfo   null      try           applicationInfo   packageManager getApplicationInfo your apppackagename  0         catch  PackageManager NameNotFoundException e            e printStackTrace              if  applicationInfo    null               not installed it will open your app directly on playstore         startActivity new Intent Intent ACTION VIEW  Uri parse  quot https   play google com store apps details id  quot    your apppackagename           else              Installed         Intent LaunchIntent   packageManager getLaunchIntentForPackage your apppackagename           startActivity  LaunchIntent

A simpler implementation using Kotlin   fun PackageManager isAppInstalled packageName  String   Boolean           getInstalledApplications PackageManager GET META DATA                   firstOrNull   it packageName    packageName      null   And call it like this  seeking for Spotify app    packageManager isAppInstalled  com spotify music

This code checks to make sure the app is installed  but also checks to make sure it s enabled    private boolean isAppInstalled String packageName        PackageManager pm   getPackageManager        try           pm getPackageInfo packageName  PackageManager GET ACTIVITIES           return pm getApplicationInfo packageName  0  enabled            catch  PackageManager NameNotFoundException e            e printStackTrace            return false

Somewhat cleaner solution than the accepted answer  based on this question    public static boolean isAppInstalled Context context  String packageName        try           context getPackageManager   getApplicationInfo packageName  0           return true            catch  PackageManager NameNotFoundException e            return false            I chose to put it in a helper class as a static utility  Usage example   boolean whatsappFound   AndroidUtils isAppInstalled context   com whatsapp      This answer shows how to get the app from the Play Store if the app is missing  though care needs to be taken on devices that don t have the Play Store

Cleaner solution  without try-catch  than the accepted answer  based on AndroidRate Library    public static boolean isPackageExists  NonNull final Context context   NonNull final String targetPackage        List lt ApplicationInfo gt  packages   context getPackageManager   getInstalledApplications 0       for  ApplicationInfo packageInfo   packages            if  targetPackage equals packageInfo packageName                 return true                      return false
