+Steps to implement FragmentView template:
+-in template-params.xml.ftl:
+ -add the following line to common imports
+ <common src="activities"/>
+
+-Add a Fragment to show behavior. In your MainActivity.java class, it will reference a Fragment
+ called (yourProjectName)Fragment.java. Create that file in your project, using the "main" source
+ folder instead of "common" or "templates".
+ For instance, if your package name is com.example.foo, create the file
+ src/main/java/com/example/foo/FooFragment.java
+
+
+-Within this fragment, make sure that the onCreate method has the line
+ "setHasOptionsMenu(true);", to enable the fragment to handle menu events.
+
+-In order to override menu events, override onOptionsItemSelected.
+
+-refer to sampleSamples/fragmentViewSample for a reference implementation of a
+project built on this template.

+ Vendor-specific AIDs should always start with an "F", according to the ISO 7816 spec. We
+ recommended vendor-specific AIDs be at least 6 characters long, to provide sufficient
+ uniqueness. Note, however, that longer AIDs may impose a burden on non-Android NFC terminals.
+ AIDs may not exceed 32 characters (16 bytes).
+
+ Additionally, AIDs must always contain an even number of characters, in hexadecimal format.
+
+ In order to avoid prompting the user to select which service they want to use when the device
+ is scanned, this app must be selected as the default handler for an AID group by the user, or
+ the terminal must select *all* AIDs defined in the category simultaneously ("exact match").

+ If category="payment" is used for any aid-groups, you must also add an android:apduServiceBanner
+ attribute above, like so:
+
+ android:apduServiceBanner="@drawable/settings_banner"
+
+ apduServiceBanner should be 260x96 dp. In pixels, that works out to...

+
+ The apduServiceBanner is displayed in the "Tap & Pay" menu in the system Settings app, and
+ is only displayed for apps which implement the "payment" AID category.
+
+ Since this sample is implementing a non-standard card type (a loyalty card, specifically), we
+ do not need to define a banner.
+
+ Important: category="payment" should only be used for industry-standard payment cards. If you are
+ implementing a closed-loop payment system (e.g. stored value cards for a specific merchant
+ or transit system), use category="other". This is because only one "payment" card may be
+ active at a time, whereas all "other" cards are active simultaneously (subject to AID
+ dispatch).

+Steps to implement FragmentView template:
+-in template-params.xml.ftl:
+ -add the following line to common imports
+ <common src="activities"/>
+
+-Add a Fragment to show behavior. In your MainActivity.java class, it will reference a Fragment
+ called (yourProjectName)Fragment.java. Create that file in your project, using the "main" source
+ folder instead of "common" or "templates".
+ For instance, if your package name is com.example.foo, create the file
+ src/main/java/com/example/foo/FooFragment.java
+
+
+-Within this fragment, make sure that the onCreate method has the line
+ "setHasOptionsMenu(true);", to enable the fragment to handle menu events.
+
+-In order to override menu events, override onOptionsItemSelected.
+
+-refer to sampleSamples/fragmentViewSample for a reference implementation of a
+project built on this template.
