How to get package name from anywhere

Question

I am aware of the availability of Context getApplicationContext   and View getContext    through which I can actually call Context getPackageName   to retrieve the package name of an application   They work if I call from a method to which a View or an Activity object is available  but if I want to find the package name from a totally independent class with no View or Activity  is there a way to do that  directly or indirectly

You can use undocumented method android app ActivityThread currentPackageName      Class lt   gt  clazz   Class forName  android app ActivityThread    Method method    clazz getDeclaredMethod  currentPackageName   null   String appPackageName    String  method invoke clazz  null     Caveat  This must be done on the main thread of the application   Thanks to this blog post for the idea  http   blog javia org static-the-android-application-package

If you use gradle build  use this  BuildConfig APPLICATION ID to get the package name of the application

An idea is to have a static variable in your main activity  instantiated to be the package name   Then just reference that variable   You will have to initialize it in the main activity s onCreate   method   Global to the class   public static String PACKAGE NAME    Then     Override public void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout main        PACKAGE NAME   getApplicationContext   getPackageName        You can then access it via Main PACKAGE NAME

For those who are using Gradle  as  Billda mentioned  you can get the package name via   BuildConfig APPLICATION ID   This gives you the package name declared in your app gradle   android       defaultConfig           applicationId  com domain www            If you are interested to get the package name used by your java classes  which sometimes is different than applicationId   you can use  BuildConfig class getPackage   toString     If you are confused which one to use  read here      Note  The application ID used to be directly tied to your code s   package name  so some Android APIs use the term  package name  in   their method names and parameter names  but this is actually your   application ID  For example  the Context getPackageName   method   returns your application ID  There s no need to ever share your code s   true package name outside your app code

If with the word  anywhere  you mean without having an explicit Context  for example from a background thread   you should define a class in your project like   public class MyApp extends Application       private static MyApp instance       public static MyApp getInstance             return instance             public static Context getContext            return instance             or return instance getApplicationContext                Override     public void onCreate             instance   this          super onCreate              Then in your manifest you need to add this class to the Name field at the Application tab  Or edit the xml and put   lt application     android name  com example app MyApp      android icon   drawable icon      android label   string app name                   lt activity                  and then from anywhere you can call  String packagename  MyApp getContext   getPackageName      Hope it helps

Create a java module to be initially run when starting your app  This module would be extending the android Application class and would initialize any global app variables and also contain app-wide utility routines -   public class MyApplicationName extends Application        private final String PACKAGE NAME    com mysite myAppPackageName        public String getPackageName     return PACKAGE NAME        Of course  this could include logic to obtain the package name from the android system  however  the above is smaller  faster and cleaner code than obtaining it from android   Be sure to place an entry in your AndroidManifest xml file to tell android to run your application module before running any activities -   lt application      android name   MyApplicationName            gt    Then  to obtain the package name from any other module  enter  MyApp myApp    MyApp  getApplicationContext    String myPackage   myApp getPackageName      Using an application module also gives you a context for modules that need but don t have a context
