Examples with FileWrapper com.android.io.FileWrapper used on opensource projects

Example 1 with FileWrapper

use of com.android.io.FileWrapper in project bazel by bazelbuild.

the class AndroidResourceProcessor method processDataBindings.

   * declarations over those resources, populates the output file, and creates a new resources
   * directory with data binding expressions stripped out (so aapt, which doesn't understand
   * data binding, can properly read them).

   * <p>Returns the resources directory that aapt should read.
