ibaker e414f0d2ac Clean up Util.inferContentType methods
This fixes some small niggles:
1. `inferContentType(String)` is documented to take a path, but in the
   tests we're passing full URIs.
2. A `String` parameter is usually a path, but also a MIME type or an
   extension. In the new methods, the meaning of a `String` parameter
   is always clear from the name of the method.
3. `inferContentType(String)` is always passed an extension in
   'production' code (which has to be manually prefixed with a dot).
4. `inferContentType(Uri, @Nullable String)` always ignores the Uri if
   the String is non-null. IMO this logic is clearer to a reader if it's
   just in-lined at the call-site.

These methods are used from the demo apps, so will be part of the stable
API.

Demos

This directory contains apps that demonstrate how to use Android media modules, like ExoPlayer. Browse the individual demos and their READMEs to learn more.

Running a demo

From Android Studio

  • File -> New -> Import Project -> Specify the root media folder.
  • Choose the demo from the run configuration dropdown list.
  • Click Run.

Using gradle from the command line:

  • Open a Terminal window at the root media folder.
  • Run ./gradlew projects to show all projects. Demo projects start with demo.
  • Run ./gradlew :<demo name>:tasks to view the list of available tasks for the demo project. Choose an install option from the Install tasks section.
  • Run ./gradlew :<demo name>:<install task>.

For example, ./gradlew :demo:installNoDecoderExtensionsDebug installs the ExoPlayer demo app in debug mode with no optional modules.
