            content.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_LOW);
            Bitmap bitmap = content.getDrawingCache();

            String path = Environment.getExternalStorageDirectory().getAbsolutePath();

                ostream = new FileOutputStream(file);
                bitmap.compress(CompressFormat.PNG,50, ostream);
                ostream.flush();
                ostream.close();
                Toast.makeText(getApplicationContext(), " :) Image saved in "+ path+"/"+file_name, 5000).show();
            } catch (Exception e) {
                e.printStackTrace();
                Toast.makeText(getApplicationContext(), e.toString()+"error", 5000).show();

我自己找到解决方案，该解决方案是存储直通媒体商店的形象这里是我的code的正常工作

I myself find the solution , the solution is to store the image thru media store here is my code that is working correctly

View content = drawView;
                content.setDrawingCacheEnabled(true);
                content.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_AUTO);
                Bitmap bitmap;
                bitmap = content.getDrawingCache();             
                String file_name="MyImage"+System.currentTimeMillis()+".jpg";

                ContentValues values = new ContentValues();
                values.put(Images.Media.TITLE,"MyImage");                   
                values.put(Images.Media.DESCRIPTION,"Advanced Practice");                   
                values.put(Images.Media.MIME_TYPE, "image/jpeg");
                Uri url = null;

                try 
                {   
                    url = getContentResolver().insert(MediaStore.Images.Thumbnails.getContentUri("external"), values);
                    MediaStore.Images.Media.insertImage(getContentResolver(), bitmap,"MyImage","Advanced Practice");                     
                    Toast.makeText(getApplicationContext(), " :) Image saved in /sdcard/DCIM/Camera/"+file_name, 5000).show();
                } 
                catch (Exception e) 
                {
                    e.printStackTrace();
                    Toast.makeText(getApplicationContext(), e.toString()+"error", 5000).show();
                }
