I m trying to install apps from Google Play  I can understand that on opening the Google Play store URL  it opens the Google Play and when I press the back button  the activity resumes   Intent marketIntent   new Intent Intent ACTION VIEW  Uri parse appURL    marketIntent addFlags Intent FLAG ACTIVITY NO HISTORY   Intent FLAG ACTIVITY CLEAR WHEN TASK RESET   startActivity marketIntent     When I went back to the activity  I tried calling this onResume   to check if the app is installed  but I receive an error    Override protected void onResume         super onResume        boolean installed   false      while   installed            installed      appInstalledOrNot APPPACKAGE           if  installed                 Toast makeText this   App installed   Toast LENGTH SHORT  show                       private boolean appInstalledOrNot String uri      PackageManager pm   getPackageManager      boolean app installed   false    try         pm getPackageInfo uri  PackageManager GET ACTIVITIES         app installed   true        catch  PackageManager NameNotFoundException e          app installed   false        return app installed       The error is as follows      E AndroidRuntime 796   java lang RuntimeException  Unable to start   activity   ComponentInfo com example appinstaller com example appinstaller MainActivity     android content ActivityNotFoundException        No Activity found to handle Intent   act android intent action VIEW   dat market   details id com package name flg 0x40080000     I guess the activity is onPause    Is there a better way to implement it  I m trying to check if the app has finished installing

Since Android 11  API level 30   most user-installed apps are not visible by default  In your manifest  you must statically declare which apps you are going to get info about  as in the following   lt manifest gt       lt queries gt           lt  -- Explicit apps you know in advance about  -- gt           lt package android name  quot com example this app quot   gt           lt package android name  quot com example this other app quot   gt       lt  queries gt                lt  manifest gt   Then   RobinKanters  answer works  private boolean isPackageInstalled String packageName  PackageManager packageManager        try           packageManager getPackageInfo packageName  0           return true        catch  PackageManager NameNotFoundException e            return false                     This will return true on Android 11 if the app is installed     since we declared it above in the manifest  isPackageInstalled  quot com example this app quot   pm       This will return false on Android 11 even if the app is installed  isPackageInstalled  quot another random app quot   pm     Learn more here   The migration documentation The dedicated documentation page  has more information  The official blog post

Try this   private boolean isPackageInstalled String packageName  PackageManager packageManager        try           packageManager getPackageInfo packageName  0           return true        catch  PackageManager NameNotFoundException e            return false            It attempts to fetch information about the package whose name you passed in  Failing that  if a NameNotFoundException was thrown  it means that no package with that name is installed  so we return false   Note that we pass in a PackageManager instead of a Context  so that the method is slightly more flexibly usable and doesn t violate the law of Demeter  You can use the method without access to a Context instance  as long as you have a PackageManager instance   Use it like this   public void someMethod                     PackageManager pm   context getPackageManager        boolean isInstalled   isPackageInstalled  com somepackage name   pm

Faster solution   private boolean isPackageInstalled String packagename  PackageManager packageManager        try           packageManager getPackageGids packagename           return true        catch  NameNotFoundException e            return false            getPackageGids is less expensive from getPackageInfo  so it work faster   Run 10000 on API 15 Exists pkg  getPackageInfo  nanoTime   930000000 getPackageGids  nanoTime   350000000 Not exists pkg  getPackageInfo  nanoTime   420000000 getPackageGids  nanoTime   380000000  Run 10000 on API 17 Exists pkg  getPackageInfo  nanoTime   2942745517 getPackageGids  nanoTime   2443716170 Not exists pkg  getPackageInfo  nanoTime   2467565849 getPackageGids  nanoTime   2479833890  Run 10000 on API 22 Exists pkg  getPackageInfo  nanoTime   4596551615 getPackageGids  nanoTime   1864970154 Not exists pkg  getPackageInfo  nanoTime   3830033616 getPackageGids  nanoTime   3789230769  Run 10000 on API 25 Exists pkg  getPackageInfo  nanoTime   3436647394 getPackageGids  nanoTime   2876970397 Not exists pkg  getPackageInfo  nanoTime   3252946114 getPackageGids  nanoTime   3117544269   Note  This will not work in some virtual spaces  They can violate the Android API and always return an array  even if there is no application with that package name  In this case  use getPackageInfo

Robin Kanters  answer is right  but it does check for installed apps regardless of their enabled or disabled state   We all know an app can be installed but disabled by the user  therefore unusable   This checks for 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            You can put this method in a class like Utils and call it everywhere using   boolean isInstalled   Utils isPackageInstalled  com package name   context getPackageManager
