我的应用程序某处有内存泄漏（我猜？）。而且我真的不知道在哪里，我一直在尝试遵循几个链接来解释关闭 OOM 错误的不同方法，但没有运气。
问题是，我有一个包含 209 页的 viewpager（动态加载数据，并且所有 209 页都使用同一个片段）
在开始出现任何内存错误之前，我可以滚动浏览大约 20 页左右。所有图像都由 Universal-Image-Loader 加载，并且只缓存在磁盘上，而不是在内存中。
我正在使用 FragmentStatePagerAdapter。
这是代码，我真的希望你们能找到我找不到的东西。另外，如果您发现任何应该不同的东西，可以优化或任何东西，请告诉。：
活动：
public class MovieInfo extends SherlockFragmentActivity{
MyAdapter mAdapter;
ViewPager mPager;
static ArrayList<Movie> items;
public static class MyAdapter extends FragmentStatePagerAdapter {
public MyAdapter(FragmentManager fm) {
super(fm);
}
@Override
public void destroyItem(View collection, int position, Object o) {
View view = (View)o;
((ViewPager) collection).removeView(view);
view = null;
}
@Override
public int getCount() {
return items.size();
}
@Override
public Fragment getItem(int position) {
Fragment f = new MovieInfoFragment();
Bundle args = new Bundle();
args.putParcelable("item", items.get(position));
f.setArguments(args);
return f;
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.movie_info_pager);
int mIndex = getIntent().getExtras().getInt("index", 0);
DataBaseHelper db = new DataBaseHelper(this);
items = (ArrayList<Movie>) db.getAllMovies();
db.close();
mAdapter = new MyAdapter(getSupportFragmentManager());
mPager = (ViewPager)findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mPager.setCurrentItem(mIndex);
}
}

编辑：
我知道，我的应用程序出现 OutOfMemory 错误的原因是，它不会释放我的大型 viewpager 中的位图以进行垃圾收集，但是我如何让我的应用程序释放它们？（阅读：垃圾收集）当当前不在视图中时，单个上一个或单个下一个“幻灯片”？
任何帮助表示赞赏！
