abstract
classes that derive fromActivityand have the [Activity]
attribute declared on them. It then uses these classes and attributesto build the manifest. For example, consider the following code:<activity/>
element to be generated, you need to use the[Activity]
custom attribute:[Activity]
attribute has no effect on abstract
types; abstract
types are ignored.Name
property:Name
property only forbackward-compatibility reasons, as such renaming can slow down typelookup at runtime. If you have legacy code that expects the defaulttype name of the activity to be based on the lowercased namespace andthe class name, seeAndroid Callable Wrapper Namingfor tips on maintaining compatibility./manifest/application/activity/@android:label
.In most cases, this value will differ from your class name. To specify your app's label on the title bar,use the Label
property.For example:MainLauncher
property. For example:Icon
property to specify the icon to use. For example:INTERNET
permission, the followingelement is added to Properties/AndroidManifest.xml:INTERNET
and READ_EXTERNAL_STORAGE
) – these settingsare set only in the generated obj/Debug/android/AndroidManifest.xmland are not shown as enabled in the Required permissions settings.[IntentFilter]
custom attribute. You can specify which actions are appropriate foryour activity with theIntentFilter
constructor, and which categories are appropriate with theCategories
property. At least one activity must be provided (which is whyactivities are provided in the constructor). [IntentFilter]
can beprovided multiple times, and each use results in a separate<intent-filter/>
element within the <activity/>
. For example:<application>
element and its counterpart, theApplicationcustom attribute. Note that these are application-wide (assembly-wide)settings rather than per-Activity settings. Typically, you declare<application>
properties for your entire application and thenoverride these settings (as needed) on a per-Activity basis.Application
attribute is added toAssemblyInfo.cs to indicate that the application can be debugged,that its user-readable name is My App, and that it uses theTheme.Light
style as the default theme for all activities:Theme.Light
style. If you set an Activity's theme toTheme.Dialog
, only that Activity will use the Theme.Dialog
stylewhile all other activities in your app will default to theTheme.Light
style as set in the <application>
element.Application
element is not the only way to configure<application>
attributes. Alternately, you can insert attributesdirectly into the <application>
element ofProperties/AndroidManifest.xml. These settings are mergedinto the final <application>
element that resides inobj/Debug/android/AndroidManifest.xml. Note that the contents ofProperties/AndroidManifest.xml always override data provided bycustom attributes.<application>
element; for more information about these settings,see thePublic Propertiessection ofApplicationAttribute.Authentication Error: Xcode 7.3 or later is required to continue developing with your Apple ID.
