android - Using RunOnUI to pass data from a Service to an Activity -

need bit of here, trying create service uses microphone listen peaks in audio frequency. service should run in background , update ui frequency information when there peak. app launches , fc's due seems running out of memory. i've tried debugging , following threads new @ , can't seem decipher doing wrong.

here activity:

public class rtaactivity extends activity  {      private static final string tag = "rtatest";     private intent intent;      @override     public void oncreate(bundle savedinstancestate){         super.oncreate(savedinstancestate);         setcontentview(r.layout.rta_view);          intent = new intent(this, analyzeservice.class);      }     private broadcastreceiver broadcastreceiver = new broadcastreceiver() {         @override         public void onreceive(context context, intent intent) {             android.os.debug.waitfordebugger();  // check logcat              updateui(intent);                }     };          @override     public void onresume() {         super.onresume();                startservice(intent);         registerreceiver(broadcastreceiver, new intentfilter(analyzeservice.analyze_action));     }      @override     public void onpause() {         super.onpause();         unregisterreceiver(broadcastreceiver);         stopservice(intent);             }        private void updateui(intent intent) {         string freq = intent.getstringextra("freq");          string db = intent.getstringextra("db");         log.d(tag, freq);         log.d(tag, db);          textview tvfreq = (textview) findviewbyid(r.id.tv_freq);             textview decibels = (textview) findviewbyid(r.id.tv_decibels);         tvfreq.settext(freq);         decibels.settext(db);     } } 

and here service:

public class analyzeservice extends service { private static final string tag = "analyzerservice"; public static final string analyze_action =     "com.kjacksonmusic.glassrta.displayevent"; private final handler handler = new handler(); intent intent;    @override public void oncreate() {     super.oncreate();      intent = new intent(analyze_action);     }   @override     public void onstart(intent intent, int startid) {         handler.removecallbacks(runonui);    //sendupdatestoui         handler.postdelayed(runonui, 500); // 0.5 second      }  private runnable runonui = new runnable() {         public void run() {             //android.os.debug.waitfordebugger();  // check logcat              displayaudioinfo();                  handler.postdelayed(this, 1000); // 1 seconds         }     };          private void displayaudioinfo() {        log.d(tag, "entered displayaudioinfo");        int frequency;        audiorecord recorder;        boolean recording;                               int numcrossing,p;        short audiodata[];     int buffersize = audiorecord.getminbuffersize(8000,audioformat.channel_configuration_mono, audioformat.encoding_pcm_16bit)*3; //get buffer size use audio record  recorder = new audiorecord (audiosource.mic,8000,audioformat.channel_configuration_mono, audioformat.encoding_pcm_16bit,buffersize); //instantiate audiorecorder   recording=true; //variable use start or stop recording audiodata = new short [buffersize]; //short array pcm data put into.   while (recording) {  //loop while recording needed     if (recorder.getstate()==android.media.audiorecord.state_initialized) // check see if recorder has initialized yet.     if (recorder.getrecordingstate()==android.media.audiorecord.recordstate_stopped)           recorder.startrecording();  //check see if recorder has stopped or not recording, , make record.      else {      recorder.read(audiodata,0,buffersize); //read pcm audio data audiodata array      //now need decode pcm data using 0 crossings method        numcrossing=0; //initialize number of 0 crossings 0        (p=0;p<1000;p+=4) {              if (audiodata[p]>0 && audiodata[p+1]<=0) numcrossing++;               if (audiodata[p]<0 && audiodata[p+1]>=0) numcrossing++;               if (audiodata[p+1]>0 && audiodata[p+2]<=0) numcrossing++;               if (audiodata[p+1]<0 && audiodata[p+2]>=0) numcrossing++;               if (audiodata[p+2]>0 && audiodata[p+3]<=0) numcrossing++;               if (audiodata[p+2]<0 && audiodata[p+3]>=0) numcrossing++;               if (audiodata[p+3]>0 && audiodata[p+4]<=0) numcrossing++;               if (audiodata[p+3]<0 && audiodata[p+4]>=0) numcrossing++;               }//for p          (p=(buffersize/4)*4;p<buffersize-1;p++) {               if (audiodata[p]>0 && audiodata[p+1]<=0) numcrossing++;               if (audiodata[p]<0 && audiodata[p+1]>=0) numcrossing++;               }           frequency=numcrossing*4;         intent.putextra("freq", frequency);         intent.putextra("db", 100);  ///place holder now.          sendbroadcast(intent);                      }//else recorder started      } //while recording      if (recorder.getstate()==android.media.audiorecord.recordstate_recording) recorder.stop(); //stop recorder before ending thread     recorder.release(); //release recorders resources     recorder=null; //set recorder garbage collected.         } // run       @override     public ibinder onbind(intent intent) {         return null;     }      @override     public void ondestroy() {                handler.removecallbacks(runonui);       //sendupdatestoui         super.ondestroy();     }      }
