Currently our Android compativility library only has a method
TextView.setText(String). With respect to the allowed input types this
less flexible than the original Android method but it works. Since
java.lang.String implements java.lang.CharSequence code using this
method compiles with our compat lib as well as with the regular Android SDK.
