Rename test.  :)

Oops. thanks!

         TestUrlRequestListener listener = new TestUrlRequestListener();
         UrlRequest urlRequest = mActivity.mUrlRequestContext.createRequest(
-                NativeTestServer.getRedirectToEchoBody(), listener, listener.getExecutor());
+                NativeTestServer.getEchoBodyURL(), listener, listener.getExecutor());
 
         TestUploadDataProvider dataProvider = new TestUploadDataProvider(
                 TestUploadDataProvider.SuccessCallbackMode.SYNC, listener.getExecutor());
+        dataProvider.addRead("test hello".getBytes());

Suggest a second test with two reads, and the second having a 0-length body.

         dataProvider.setChunked(true);
-        try {
-            urlRequest.setUploadDataProvider(dataProvider, listener.getExecutor());
-            fail("Exception not thrown");
-        } catch (IllegalArgumentException e) {
-            assertEquals("Chunked uploads not supported.", e.getMessage());
-        }
+        urlRequest.setUploadDataProvider(dataProvider, listener.getExecutor());
+        urlRequest.addHeader("Content-Type", "useless/string");
+
+        assertEquals(-1, dataProvider.getLength());
+
+        urlRequest.start();
+        listener.blockForDone();
+
+        // 1 read call for the first data chunk, 1 for final chunk.
+        assertEquals(2, dataProvider.getNumReadCalls());
+        assertEquals("test hello", listener.mResponseAsString);
     }
