I am developing on Android 2.3.3 API Lv10. My app uses the ‘LoaderManager’ interface to load images in the background, and the images are displayed in a ViewPager. If I repeat viewing the images, the app will crash eventually. It looks like the app allocate memory to fast, and the GC is not able to release some of it.<\/p>\n

Is there any way to track which object is hold in memory?<\/p>\n
