Android Question Activity.RemoveAllViews VS Activity.Finish

Can you post the error log?

Are you loading any large bitmaps when the activity is created?

I have a activity with many panels, I can go through the sliding panles with the Erel class, each panel has many ImageView loaded with loadbitmapsample.

When the user selects an ImageView, it is called an activity that contains inside a customlistview, each element has two ImageView, so I want to free up more memory as much as possible, because in some devices such as the "Galaxy Tab 2 7" "is generated Out of memory error.

But I noticed that if I call startActivity Activity.finish and after the memory is not clean, but if I call Activity.RemoveAllViews> Activity.Finish> startActivity, there is no error.

So I guess that activity.finish does not release all the memory.

You said that there is a library os to check the remaining memory available, you may publish a sampling line so that I can check what exactly happens?

Your best solution is to only load the images once and save them as process global variables. You can use a Map to implement a simple cache.

Images should be released when there are no more live references to them. However it may not happen immediately.

Thanks for your reply .
unfortunately the images are taken from the user with the camera , so one imageview per photo, but i found my way ,

1) first thing is to load the image in this way:


in this way the resized bitmap will fit perfectly with the imageview.

2) For second i remove all views from the caller activity so the memory is much free as possible .
