how to capture whole layout when layout exceeds screensize in android -


in application zooming layout when zoom layout want capture layout.i tried below code capturing content visible in screen.please me how capture layout.

       view content = findviewbyid(r.id.main_container);     content.setdrawingcacheenabled(true);     bitmap bitmap = content.getdrawingcache();     // actual width of image (img bitmap object)     // int width = bitmap.getwidth();     // int height = bitmap.getheight();      // recreate new bitmap , set          bitmap = bitmap.createbitmap(bitmap.createbitmap(                 l1.getwidth() * 2, l1.getheight() * 2,                 bitmap.config.argb_8888));       // bitmap mb = bitmap.copy(bitmap.config.argb_8888, true);     canvas bitmapcanvas = new canvas();     bitmapcanvas.setbitmap(bitmap);     bitmapcanvas.scale(2.0f, 2.0f);     content.draw(bitmapcanvas);     bytearrayoutputstream out = new bytearrayoutputstream();      bitmap.compress(bitmap.compressformat.png, 100, out);      file imagesfolder = new file(environment.getexternalstoragedirectory(),             "saved_images");     imagesfolder.mkdirs();     string filename = "final-" + string.valueof(n) + ".jpg";     file output = new file(imagesfolder, filename);     while (output.exists()) {         n++;         filename = "final-" + string.valueof(n) + ".jpg";         output = new file(imagesfolder, filename);     }     uri urisavedimage = uri.fromfile(output);     outputstream imagefileos;     try {         imagefileos = getcontentresolver().openoutputstream(urisavedimage);         imagefileos.write(out.tobytearray());         imagefileos.flush();         imagefileos.close();         } catch (filenotfoundexception e) {         e.printstacktrace();     } catch (ioexception e) {         e.printstacktrace();     }     content.setdrawingcacheenabled(false);

here's way grabbing screenshot of layout. i'm writing out of head code may contain errors (can't verify right now);

viewgroup bg = (viewgroup) findviewbyid(r.id.your_layout_id); bitmap screenshot = bitmap.createbitmap(vg.getwidth(), vg.getheight(),                                         bitmap.config.rgba8888); canvas c = new canvas(screenshot); vg.draw(c);

now i'm not sure whether works better should draw @ least according documentation.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
