+# Android Intents
+
+### Requirements
+For this project, you will be creating a multi page app. The first page will allow the user to import images and list them by name. The second will allow the user to view and edit details of a single image (these are details that you choose and do not need to be permanent). The third will allow the user to view the selected image in full screen.  
+This will encompass many of the skills you have developed over the Intro to Android course. We'll give you a few tips on how to process.
+
+### Part 1 - Create an Android Studio Project
+
+1. Create a new Android Studio project
+2. Name the project "Image Viewer"
+3. Make sure that the target API level is below that of your testing environment.
+
+### Part 2 - Build layout for the Add and List activity
+
+1. Open the app's activity_main.xml file.
+2. Change the parent viewgroup to a linear layout
+> Set the `orientation` attribute to `vertical` to best utilize the screen real estate
+4. Add a `ScrollView` to list all previously viewed images. Give it a linear layout child.
+5. Add a `Button` so the user select an image to add to the list
+6. Add IDs to all the views that will need to be accessed in the code.
+
+### Part 3 - Create an ImageData Class
+
+1. Create a class to store desired data from retreived image.
+> The only required data is a name and a `Uri` stored as a String.
+> Convert a `Uri` to a string with `.toString()` method and back with `Uri.parse(stringUri)`.  
+2. Class must contain the keywords `implements Serializable` in the class signature
+> This provides the necessary methods to the `Intent.putExtra` method can store the class's data  
+3. Make all the data members private and create getters and setters for them
+> The `Uri` setter should convert the `Uri` to a `String` and the getter should convert it back.
+> This is because a `Uri` object can't be serialized.
+
+### Part 4 - Write a method to generate a TextView object
+
+1. Add a `TextView` to your layout xml file.
+2. Manipulate its attributes until you find a design that you like.
+3. Write a method that will create a `TextView` object and add those attributes to it programatically.
+4. The method must accept a `String` to be the view's text attribute and an `int` which is the index where the element is stored in the `List`.
+5. Return the `TextView` from the method.
+6. To add the `TextView` to the ui, pass it to your `ScrollView`'s `LinearLayout` child's `.addView()` method.  
+
+### Part 5 - Create an Intent to Get an Image
+
+1. Create a listener and event handler for the add button in MainActivity.java  
+2. In the click event method, write a Get Content Implicit Event that retreives an image from the system.  
+3. Broadcast that intent with a `startActivityForResult` method call.  
+4. Override the `onActivityResult` method to create the `ImageData` object, add it to an `ArrayList` class data memeber have a `TextView` generated and added to your UI.  
+
+### Part 6 - Test your App
+
+1. Thoroughly test this activity before moving on.
+
+### Part 7 - Add a click listener to the items in the list
+
+1. In your `TextView` generator give the `TextView` object a listener that will get the tag from the element, use that to pull the `ImageData` object from the `List`.
+2. Use `intent.putExtra()` to add the object to the intent
+
+### Part 8 - Build the layout for the details activity
+
+1. Design a layout that will display details about the file.
+2. Display the image somewhere in the layout.
+
+### Part 9 - Retreive the Object from the Intent
+
+1. Use `getIntent()` to get the intent used to launch this activity.
+2. Use the `intent.getSerializableExtra()` method to retreive the serialized data and then cast it to `ImageData`.
+  * the final line of code should look something like this `myObject = (ImageData)intent.getSerializableExtra("KEY")`  
+
+### Part 10 - Display object
+
+1. Show the desired data in the UI.
+2. Use `.setImageURI()` to get the image for your `ImageView` to the one in our `ImageData`
+
+### Part 11 - Test your App
+
+1. Thoroughly test these two activities before moving on.
+
+
+## Challenge (Optional)
+### Part 12 - Build Fullscreen Layout
+
+1. Add an activity
+> You can pick a Fullscreen activity from the new activity wizard and adapt it to your needs, or build an empty activity with full screen imageview element
+2. Adapt generated layout to fit your needs
+
+### Part 13 - Built an intent to go to the next activity
+
+1. Build an intent to go to the next activity, but instead of passing the whole object, just pass the `String` value for the Uri.
+
+### Part 14 - Add the image to the UI
+
+1. Use the `intent.getStringExtra()` method to retreive the `String` `Uri` from the `Intent`  
+2. Use `.setImageURI()` to update the `Uri`
+
+### Submit
+Send your completed app to your Project Manager.
