in Corona and Lua - how do I completely remove a display object (an image) from the screen and also from memory
I am trying to fix my memory leak in Lua.
To test, I am creating 100,000 images on screen and recording them.
Then I remove them from the display. This works.
The problem is that the memory used never reduces back to that before the creation.
Here is my code:
local _storeContents = {}
local function OnDebugTest( event )
for i = 1, 100000, 1 do
img = display.newImage( "planet1.png", math.random()*400, math.random()*400-200 )
_group:insert(img)
table.insert(_storeContent
end
for a,b in pairs(_storeContents) do
display.remove(b)
end
_storeContents = {}
end
I am using gcinfo() to get the memory usage.
What do I need to do to fix the memory leak?

I made this change to the code:
for a,b in pairs(_storeContents) do
display.remove(b)
_storeContents [a] = nil
end
and I use this later, called from a button:
