Make sure all FDs are correctly closed.

In this kind of series of calls, it's possible that an outer call to a
constructor fails, but the inner succeeded.
Example:
try {
    is = new A(new B());
} finally {
    if (null != is) is.close();
}
In this case, if new B() succeeds but new A() throws an
exception, is stays null and the intermediate object is never
closed. This is what was happening in this instance.

Fix a bug with some text fields

Not sure when this happens exactly, but it is possible that
InputConnection#getTextBeforeCursor returns null. This
happens for example upon rotating the screen with the
composing field empty in Gmail.
In this case, StringBuilder#append will convert the null
pointer into the string "null", which is sure better than a
crash, but can have a number of bad side-effects, like
auto-caps not working.
