OK,
This is what happened:
The original title was,
how to convert .apk files to java
The title sanitizer converted it to
how to convert .apk files to java
Anonymous in her infinite wisdom decided to perform a no-op edit.
The "make sure that something in the title actually changed" code was a bit broken and did not properly squelch spaces between word boundaries. When it converted the title of the question with the "new" proposed title, it thought it changed cause a space was added.
I fixed it.
"java covert to android" shown in your screenshot (and in my review window as well) was not there in the question's revisions before: https://stackoverflow.com/posts/4573812/revisions
Given the above, it looks safe to assume that this is what was suggested in the edit. From the context, it is likely that it tries to clarify that the question covers both directions – from Java to Android and the other way around.
The meaning of the edit is vague, its spelling is bad and there is no information visible besides the Edit Summary – as if the author didn't even bother to look at the edited answer's preview. All the above sounds like too low effort to me. The edit appeared to deserve a rejection.
As for what could cause changes that appear invisible, these look entirely possible to me. In the previous edit of my answer (rev 2) I tested one particular trick to achieve that – by adding <text in angle brackets>
. The result looks pretty similar to what is shown in your screenshot. The edit summary is shown and there's nothing else besides.
If the problematic edit was indeed of <hidden in angle brackets>, then this seems to be a known issue covered in another feature request: Add a view to see the raw source of suggested edits
