 1 | Any raw assets you want to be deployed with your application can be placed in
 2 | this directory (and child directories) and given a Build Action of "AndroidAsset".
 3 | 
 4 | These files will be deployed with you package and will be accessible using Android's
 5 | AssetManager, like this:
 6 | 
 7 | public class ReadAsset : Activity
 8 | {
 9 | 	protected override void OnCreate (Bundle bundle)
10 | 	{
11 | 		base.OnCreate (bundle);
12 | 
13 | 		InputStream input = Assets.Open ("my_asset.txt");
14 | 	}
15 | }
16 | 
17 | Additionally, some Android functions will automatically load asset files:
18 | 
19 | Typeface tf = Typeface.CreateFromAsset (Context.Assets, "fonts/samplefont.ttf");

/App4/Resources/AboutResources.txt:
--------------------------------------------------------------------------------
 1 | Images, layout descriptions, binary blobs and string dictionaries can be included 
 2 | in your application as resource files.  Various Android APIs are designed to 
 3 | operate on the resource IDs instead of dealing with images, strings or binary blobs 
 4 | directly.
 5 | 
 6 | For example, a sample Android app that contains a user interface layout (main.axml),
 7 | an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png) 
 8 | would keep its resources in the "Resources" directory of the application:
 9 | 
10 | Resources/
11 |     drawable/
12 |         icon.png
13 | 
14 |     layout/
15 |         main.axml
16 | 
17 |     values/
18 |         strings.xml
19 | 
20 | In order to get the build system to recognize Android resources, set the build action to
21 | "AndroidResource".  The native Android APIs do not operate directly with filenames, but 
22 | instead operate on resource IDs.  When you compile an Android application that uses resources, 
23 | the build system will package the resources for distribution and generate a class called "R" 
24 | (this is an Android convention) that contains the tokens for each one of the resources 
25 | included. For example, for the above Resources layout, this is what the R class would expose:
26 | 
27 | public class R {
28 |     public class drawable {
29 |         public const int icon = 0x123;
30 |     }
31 | 
32 |     public class layout {
33 |         public const int main = 0x456;
34 |     }
35 | 
36 |     public class strings {
37 |         public const int first_string = 0xabc;
38 |         public const int second_string = 0xbcd;
39 |     }
40 | }
41 | 
42 | You would then use R.drawable.icon to reference the drawable/icon.png file, or R.layout.main 
43 | to reference the layout/main.axml file, or R.strings.first_string to reference the first 
44 | string in the dictionary file values/strings.xml.

 8 | The Skimmer Scanner is a free, open source app that detects common bluetooth based credit card skimmers predominantly found in gas pumps. The app scans for available bluetooth connections looking for a device with title **HC-05**. If found, the app will attempt to connect using the default password of 1234. Once connected, the letter 'P' will be sent. If a response of 'M' then there is a very high likelihood there is a skimmer in the bluetooth range of your phone (5 to 15 feet).

10 | The app *does not* obtain or download data from a given skimmer nor does it report any information to local authorities.
11 | 
12 | Skimmer Scanner is free, open source, and currently available for Android available [here](https://play.google.com/store/apps/details?id=skimmerscammer.skimmerscammer). Please help us make it better! We are not mobile app developers and can use all the help we can get. We very much need an iOS version. Thank you!
