how can I create a content provider which every other app can read but none can write?

Question

I understand that export=true will set the content provider to be readable and writable by all other apps. But now I only want content provider to be readable by everyone but writable by no one. How can I do that?

Answer 1

My approach to this problem would be creating two ContentProviders. The exported one would have only the implementation of the query() method, the insert(), update(), and delete(). The second one (private), would not be exported and it would contain the implementation of all the methods. You could use inheritance to avoid repetition of the code. You'd have to register them both in the AndroidManifest.xml. Keep in mind that the ContentProviders would have to have different authorities but they can still operate on the same data.
