Body
I'm trying to crack down on a memory leak which is causing the heap to run out of memory and the GC to get invoked. A lot. Logcat is filled with messages like this: <blockquote> 11-27 20:54:39.052: DEBUG/dalvikvm(32167): GC_CONCURRENT freed 405K, 5% free 11046K/11591K, paused 2ms+3ms </blockquote> I used the DDMS Allocation tracker to see if there was anything in particular getting allocated more than usual, and the instant that I clicked the 'Get Allocations' button in Eclipse, the list was filled with java.util.AbstractList$SimpleListIterator They get allocated during the main game loop, so there are lots, and I believe this is what is eating the heap memory.(there are approx. 509 allocations of SimpleListIterator) However, DDMS is telling me that they are being allocated wherever there is a for-each loop, which I think is strange. o_O Normally I would use a regular for loop, but <a href="http://developer.android.com/guide/practices/design/performance.html#foreach" rel="nofollow">this article</a> recommends using the for-each loop instead since it's faster, but it mentions nothing about its memory usage Could all these allocations be the result of using the for-each loop instead of the regular for loop? (It'll take a while to go in and change every single for-each loop in my app, so I'd rather ask first) If they are, then is this normal? Is it a programming error on my part? UPDATE I changed the for-each loops to regular for loops and the completely solved the problem. I still think its dumb though that I had to do that

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
