Answer 1

Use : getPackageManager().getPackageInfo(getPackageName(), 0).packageName Or just MyContext.getPackageName()

You can also create a function:

public String getPackageName(Context context) {
    return context.getPackageName();
}

Answer 2

The following constant is available without the need for a context.

BuildConfig.APPLICATION_ID

Answer 3

I think getPackageName() is available directly within activity without calling getApplicationContext. Checked it myself.Working good.

Answer 4

getApplicationContext().getPackageName() will give the package name.

Answer 5

List<ApplicationInfo> packages;
    PackageManager pm;
    pm = getPackageManager();
             get a list of installed apps.
            packages = pm.getInstalledApplications(0);

ActivityManager mActivityManager = (ActivityManager) context
                .getSystemService(Context.ACTIVITY_SERVICE);

   for (ApplicationInfo packageInfo : packages) {
   //packageInfo.packageName contains package name


                      }

Answer 6

you can create a Util Class this way:

public class AppInfo{
  private static Context cxt;
  public static String PACKAGE_INFO;
  public static String init(Context context){
    cxt = context;
    PACKAGE_INFO = cxt.getPackageName();
  }
}

then you can use it this way

public class MyActivity extends Activity{
  @Override
  public void onCreate(Bundle bundle){
    ...
    AppInfo.init(getApplicationContext());
    ...
  }
}

then you can call it this way:

public class someClass{
  public void someMethod(){
    String packageInfo = AppInfo.PACKAGE_INFO;
    //Do what you wish
  }
}
