I noticed an odd memory increase in one of my Activities. Hence I ran a little test: I opened the dialog multiple times (open – close – open – close ….) and the memory kept increasing. So I used the DDMS to dump an HPROF file and opened it in MAT (Memory analyzer). The leak suspect report indicated, that the main reason for the growing memory consumption was this:
So I did a histogramm, to check that dialog I ran my tests on and what’s keeping it alive. Turns out, it’s kept alive by it’s AutoCompleteTextViews, which in turn are kept alive by android.widget.TextView$IClipboardDataPasteEventImpl. However there are no immediate dominators for IClipboardDataPasteEventImpl (except of course the GC Root). I tried to find that IClipboardDataPasteEventImpl on the internet and I searched grepcode (the android source), but the only thing I could come up with was this blog entry. I can’t read whatever language that is, but what I could read are the English words thrown in, which indicates, that it might be a bug on the Samsung Galaxy SII (the phone I am using, running android 2.3.x), related to the ClipboardManager. However I am unsure of this (I want to fix this, hence I am disinclined to simply accept it to be an unfixable bug) and I have no clue, where this Clipboard is spawned and why. I would greatly appreciate any pointers/ideas on the matter.
My memleak investigation also brought me here. Im having problems with Activity leaking over EditText. android.widget.TextView$IClipboardDataPasteEventImpl object is holding the EditText which is holding the activity. This happens on Samsung Galaxy Tab 10.1, and Galaxy Tab 2 10.1, 7.0. I wasn’t able to reproduce it on other non Samsung devices (Asus, Acer).
The bad thing is that I didn’t find a solution for it yet 🙂
