Android Content Provider Query by authority substring or by signatures

Question

I want to get a list of content providers that exist on a device for a given authority substring. Each of the providers I will call must have the same signature.

I found that I can get all providers on a device and loop through each of them but I thought there might be a more efficient way. ( Get a list of available Content Providers )

Answer 1

No, the solution outlined in that answer is as good as you are going to get. The concept of "authority substring" is your invention, not a concept intrinsic to Android.
