+## The order of making a android app
+
+### 1. Layout
+When you've created a project you need to make the layout of the app. This is done in the `res/layout/activity_main.xml` file. This file is a xml file that describes the layout of the app. If the folder doesnt exist you can create it by right clicking on the `res` folder and selecting `New -> Android Resource File`. There you can add qualifiers to the file. Qualifiers are used to specify what kind of properties its has. 
+
+### 2. Variables for the layout
+When you're dragging and droppign things in you can add a recource name to the object. This is used to reference the object in the code. You can add a recource name by clicking on the object and then going to the `Attributes` tab. There you can add a recource name. That recource name is then used to reference the object in the code.
+
+### 3. Code
+After you made the layout you can start writing code in the `MainActivity.java` file. This file is located in the `java/com.example.myfirstapp` folder. This file is the main file of the app and is the file that is run when the app is started. 
+
+### 4. Permissions
+
+If you want to use a certain permission in your app you need to add the permission to the `AndroidManifest.xml` file. This file is located in the `app` folder. You can add a permission like this:
+    
+```xml
+<uses-permission android:name="android.permission.INTERNET"/>
+```
