R java not updating android
To access these files programmatically, they are assigned a unique resource ID.
This resource ID is an integer defined in a special class called class should not be manually edited, as any changes that are made to it will be overwritten by Xamarin. When referencing resources programmatically (in code), they can be accessed via the Resources class hierarchy which uses the following syntax: attribute set to @drawable/flag.
Android is a bit more forgiving; it will support both uppercase and lowercase filenames.
The convention for image names is to use lowercase with underscores as separators (for example, my_image_name.png).
For example, you can create a drawable resource that is an alias for another drawable resource: This sounds redundant, but can be very useful when using alternative resource. A style attribute resource allows you to reference the value of an attribute in the currently-applied theme.
Referencing a style attribute allows you to customize the look of UI elements by styling them to match standard variations supplied by the current theme, instead of supplying a hard-coded value.
For example, if you have the following resource file that includes a color resource and a string resource: In this case you don't need to specify the package name in the resource reference because the resources are from your own package.
To reference a system resource, you would need to include the package name.
I assume this means that there are still problems generating R correctly, which I am working on. Maybe I’m missing mmy head right now, but again, I’m blocked. Once you get to that point successfully, then you can start working on your own modifications again. It wasted one whole day to figure out what was wrong.
If for some reason the Build Action is not set to Android Resource, then the files will be excluded from the APK, and any attempt to load or access the resources will result in a run-time error and the application will crash.
