iam trying animate video rendered using texture view, animation works fine , when scale texture different size media player not scale fit size of texture,the video playing full screen in background , can see part of video when scale texture
code works fine on android devices running android 4.0 not work on devices later versions of android . heres code animation kindly tell me problem ..

public class mainactivity extends activity implements textureview.surfacetexturelistener{ animationset animset; textureview mytexture; mediaplayer mmediaplayer; surface s; int height; static final string logfilename = "log"; int width; protected void oncreate(bundle savedinstancestate) {   super.oncreate(savedinstancestate);    mytexture = new textureview(this);   mytexture.setsurfacetexturelistener(this);   setcontentview(mytexture);        }     @override    public void onsurfacetextureavailable(surfacetexture arg0, int arg1,    int arg2) {      string mediastoragedir = environment.getexternalstoragepublicdirectory(             environment.directory_downloads).getabsolutepath(); s = new surface(arg0);     try {        mmediaplayer= new mediaplayer();        mmediaplayer.setsurface(s);        mmediaplayer.setdatasource(mediastoragedir+"/airindia.mp4");        mmediaplayer.setaudiostreamtype(audiomanager.stream_music);        mmediaplayer.prepareasync();        mmediaplayer.setlooping(true);        mmediaplayer.setonpreparedlistener(new onpreparedlistener() {             @override             public void onprepared(mediaplayer mp) {                  mmediaplayer.start();              }         });      // animate texture          animset =new  animationset(true);      animset.addanimation(scaling);      animset.addanimation(translate);      animset.setstartoffset(20000);    animation fulscaling = new scaleanimation(1.0f, 1.3333f, 1.0f, 1.3333f);      translateanimation fulltranslate = new translateanimation(         animation.relative_to_self, 0.0f,animation.relative_to_self, -0.3333f,        0, 0.0f, 0, 0.0f);           fulltranslate.setstartoffset(10000);          animset.setduration(1000);         animset.setfillafter(true);         animset.setfillenabled(true);         fulscaling.setstartoffset(10000);          animset.addanimation(fulscaling);     animset.addanimation(fulltranslate);        mytexture.setanimation(animset);        animset.setanimationlistener(new animationlistener() {            @override           public void onanimationend(animation arg0) {                mytexture.startanimation(animset);           }            @override           public void onanimationrepeat(animation arg0) {               // todo auto-generated method stub            }            @override           public void onanimationstart(animation arg0) {               // todo auto-generated method stub            }        });         } catch (illegalargumentexception e) {     showtoast(e.getmessage());     e.printstacktrace(); } catch (securityexception e) {     showtoast(e.getmessage());     e.printstacktrace(); } catch (illegalstateexception e) {     showtoast(e.getmessage());     e.printstacktrace(); } catch (ioexception e) {     showtoast(e.getmessage());     e.printstacktrace(); }

}

if want scale textureview's contents, use settransform(). example, see adjustaspectratio() in grafika's playmovieactivity class, changes size of textureview contents match aspect ratio of video being played.

i using indy udp server read string of data. however, not know how work adata parameter. can around converting binary using bytetobin function below , convert hex using bintohex1 . feel stupid , works slow. know how can directly results without 2 conversions? thanks!! here codes: procedure tform1.idudpserver1udpread(athread: tidudplistenerthread; const adata: tidbytes; abinding: tidsockethandle); var buf: tidbytes; buffer: string; data_received: string; begin if bytestostring(adata) <> 'hello' begin buffer := hextostring('00'); setlength(buf, length(buffer)); copytidstring(buffer, buf, 0); abinding.sendto(abinding.peerip, abinding.peerport, buf); data_received := bintohex1(bytetobin(adata[1]) + bytetobin(adata[2]) + bytetobin(adata[3]) + bytetobin(adata[4]) + bytetobin(adata[5]) + bytetobin(adata[6]) + bytetobin(adata[7]) + bytetobin(adata[8]) + bytetobin(adata[9]) + bytetobin(adata[10]) + bytetobin(adata[11...
