+Steps to implement SingleView template:
+-in template-params.xml.ftl:
+ -add the following line to common imports
+ <common src="activities"/>
+
+ -add a string for the action button's text using the element name "sample_action".
+ This element should be a child of <strings>:
+ <strings>
+ ...
+ <sample_action>ButtonText</sample_action>
+ ...
+ </strings>
+
+
+
+-Add a Fragment to handle 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/singleViewSample for a reference implementation of a
+project built on this template.

+ <intro>
+ <![CDATA[
+This sample demonstrates how you can use device credentials (PIN, Pattern, Password) in your app
+to authenticate the user before they are trying to complete some actions.
+
+First you need to create a symmetric key in the Android Key Store using [KeyGenerator][1]
+which can be only be used after the user has authenticated after the user is authenticated
+with their device credentials and pass [KeyGenParameterSpec][2].
+
+By setting an integer value to the
+[KeyGeneratorSpec.Builder.setUserAuthenticationValidityDurationSeconds][3], you can consider the
+user as authenticated if the user has been authenticated with the device credentials
+within the last x seconds.
+
+Then by calling [KeyguardManager.createConfirmDeviceCredentialIntent][4], you can show a screen
+to confirm device credentials to the user.

+A sample that demonstrates to use registered fingerprints to authenticate the user in your app
+]]>
+ </description>
+
+ <intro>
+<![CDATA[
+This sample demonstrates how you can use registered fingerprints in your app to authenticate the user
+before proceeding some actions such as purchasing an item.
+
+First you need to create a symmetric key in the Android Key Store using [KeyGenerator][1]
+which can be only be used after the user has authenticated with fingerprint and pass
+a [KeyGeneratorSpec][2].
+
+By setting [KeyGeneratorSpec.Builder.setUserAuthenticationRequired][3] to true, you can permit the
+use of the key only after the user authenticate it including when authenticated with the user's
+fingerprint.
+
+Then start listening to a fingerprint on the fingerprint sensor by calling
+[FingerprintManager.authenticate][4] with a [Cipher][5] initialized with the symmetric key created.
+Or alternatively you can fall back to server-side verified password as an authenticator.
+
+Once the fingerprint (or password) is verified, the
+[FingerprintManager.AuthenticationCallback#onAuthenticationSucceeded()][6] callback is called.

+/**
+ * Launcher Activity that demonstrates the use of runtime permissions for Android M.
+ * It contains a summary sample description, sample log and a Fragment that calls callbacks on this
+ * Activity to illustrate parts of the runtime permissions API.
+ * <p>
+ * This Activity requests permissions to access the camera ({@link android.Manifest.permission#CAMERA})
+ * when the 'Show Camera' button is clicked to display the camera preview.
+ * Contacts permissions (({@link android.Manifest.permission#READ_CONTACTS} and ({@link
+ * android.Manifest.permission#WRITE_CONTACTS})) are requested when the 'Show and Add Contacts'
+ * button is
+ * clicked to display the first contact in the contacts database and to add a dummy contact
+ * directly
+ * to it. First, permissions are checked if they have already been granted through {@link
+ * android.app.Activity#checkSelfPermission(String)} (wrapped in {@link
+ * PermissionUtil#hasSelfPermission(Activity, String)} and {@link PermissionUtil#hasSelfPermission(Activity,
+ * String[])} for compatibility). If permissions have not been granted, they are requested through
+ * {@link Activity#requestPermissions(String[], int)} and the return value checked in {@link
+ * Activity#onRequestPermissionsResult(int, String[], int[])}.
+ * <p>
+ * If this sample is executed on a device running a platform version below M, all permissions
+ * declared
+ * in the Android manifest file are always granted at install time and cannot be requested at run
+ * time.
+ * <p>
+ * This sample targets the M platform and must therefore request permissions at runtime. Change the
+ * targetSdk in the file 'Application/build.gradle' to 22 to run the application in compatibility
+ * mode.
+ * Now, if a permission has been disable by the system through the application settings, disabled
+ * APIs provide compatibility data.
+ * For example the camera cannot be opened or an empty list of contacts is returned. No special
+ * action is required in this case.
+ * <p>
+ * (This class is based on the MainActivity used in the SimpleFragment sample template.)

+ <intro>
+<![CDATA[
+Android M introduced runtime permissions. Applications targeting M and above need to request their
+permissions at runtime.
+All permissions still need to be declared in the AndroidManifest. However, when accessing APIs that
+require a permission, the Activity or Fragment has to verify that the permission has been granted
+or request the missing permissions. Permissions are checked through
+Activity#requestPermissions(String[], int) and Fragment#requestPermissions(String[], int).
+Permission requests are sent through Activity#requestPermissions(String[]), and the response
+received in the callback Activity#onRequestPermissionsResult(int, permissions[], int[]).
+
+If an application targets an SDK below M, all permissions are granted at runtime and are available
+when the application is running. However, if permissions have been turned off in the system settings
+for an application targeting an SDK below M, the API will return empty or no data.
