+// TODO(primiano): remove this once Android builds of WebView are deprecated.
+// This translation unit is a no-op fallback for AwCrashReporter. This is built
+// only when building in the Android tree.
+// The rationale of this hack is to avoid the cost of maintaining breakpad in
+// the Android tree, as the WebView build in Android itself is going to be
+// deprecated soon (crbug.com/440792).
