in gyp it's one target per file so the target name should be
ui_base_touch_device_java

Done.

This is your problem. You're trying to make the rule that generates the JNI
bindings depend on the auto-generated .java code, that doesn't work right now.
The problem is that the generated .java file has to be included in one
.jar/.apk, so we have to make it a direct_dependent_settings (and not an
all_dependent_settings). Right now only the rules to generate .jar/.apk files
properly 'receive' that dependency.
You have 2 options: 
 - change build/jni_generator.gypi to forward 'generated_src_dirs' to its direct
deps,
 - have ui_java depend on ui_base_touch_device_java_enums directly.
