recycle

I've noticed that on one of my production web apps, when I manually recycle an app pool, the recycled worker process can take upwards of 60+ seconds to actually be completely destroyed, based on watching it in Task Manager. However, if I stop the app pool completely, the worker process goes away nearly instantaneously - within 1-2 seconds. So, my question is two-fold: a) Why does it take so long to destroy the process (and more meaningfully, release the resources used/locked by it) when the app pool is recycled instead of stopped; and b) Assuming that I've stopped traffic from being directed

I have integrated item is highlighted in the first launch of the app in my project. I'll use to save the selected item on the click of the adapter in the SQL database and set the value in the first launch of the app, but it does not change the background and text color. please help me in solving the issue and suggest me the right way public class LoadVehicleTypeAdapter extends RecyclerView.Adapter<LoadVehicleTypeAdapter.CarTypesHolder> { private List<TaxiTypeResponse.Message> CarTypesModelsList; private Context mContext; VehicleTypeView vehicleTypeView; int I=-1; int idd=0; Activity activity;

I know that before API 10 of Android, it was important to call recycle() for Bitmap s that aren't used anymore, since the actual raw data is stored in the native memory. However, as of API 11, Bitmap s are stored in the heap, so my question is: Is it still needed to call recycle() on Bitmap s if the API is large enough (at least 11)? What does it do if I call it on such API? s0nicYouth Official documentation tells that recycle() now is an advanced call so if you want to free your bitmap you can just write something like bitmap = null and GC will take care of everything else. 来源： https:/

Could someone tell me how to make a good mechanism for async. download of images for use in a ListView/GridView? There are many suggestions , but each only considers a small subset of the typical requirements. Below I've listed some reasonable factors (requirements or things to take into account) that I, and my collegues, are unable to satisfy at once. I am not asking for code (though it would be welcome), just an approach that manages the Bitmaps as described. No duplication of downloaders or Bitmaps Canceling downloads/assigning of images that would no longer be needed, or are likely to be

According to Android Reference Document of Bitmap.recycle() : Free the native object associated with this bitmap, and clear the reference to the pixel data. This will not free the pixel data synchronously; it simply allows it to be garbage collected if there are no other references. The bitmap is marked as "dead", meaning it will throw an exception if getPixels() or setPixels() is called, and will draw nothing. This operation cannot be reversed, so it should only be called if you are sure there are no further uses for the bitmap. This is an advanced call, and normally need not be called, since

My app can load quite large images. In an effort to be memory-conservative, I'm attempting to use a temporary bitmap to load and another for the final image after transformation: ..... finalBitmap.recycle(); finalBitmap = null; Bitmap tempBitmap = BitmapFactory.decodeStream(fin, ...); finalBitmap = Bitmap.createBitmap(tempBitmap, ....); imgview.setImageBitmap(finalBitmap); ..... Now, at this point we're done with tempBitmap, which was only needed to transport the decoded Bitmap to the transformation step in createBitmap. So: ..... tempBitmap.recycle(); tempBitmap = null; ..... And... it
