Android内容提供商的实例化顺序

Question

For my application I need to have one Content Provider started before anything else. As far as I can tell the order is independent from the order in the AndroidManifest and is not alphabetical.

How can I control the order in which Android calls the onCreate() methods of the Content Providers?

Answer 1

You need to set android:initOrder attribute. Below is what Android docs says

android:initOrder The order in which the content provider should be instantiated, relative to other content providers hosted by the same process. When there are dependencies among content providers, setting this attribute for each of them ensures that they are created in the order required by those dependencies. The value is a simple integer, with higher numbers being initialized first.
