Get Address from latitude longitude in Android

In Android to Get address from location using Geocoder
Geocoder is a class for handling geocoding and reverse geocoding.
Geocoding is the process of transforming a street address to (latitude,logitude) coordinate.
Reverse geocoding is the process of transorming (latitude,logitude) coordinate to Street address.

Here we can get address based on coordinates using Revierse geocoding
and set Address in to Textview

 Geocoder geocoder = new Geocoder(this, Locale.ENGLISH);
       try {
  List<Address> noofaddresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
   if(addresses != null) {
   Address retursAddress= noofaddresses.get(0);
   StringBuilder strReturnedAddress = new StringBuilder("Address is:\n");
   for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
    strReturnedAddress.append(returnsAddress.getAddressLine(i)).append("\n");
   }
   myAddress.setText(strReturnedAddress.toString());
  }
  else{
   myAddress.setText("No Address returned!");
  }catch(Exception e){

How to set maximum volume programmatically In Android

While i am developing one application i was stuck how to the volume of an Android application to maximum, and I saw no of  post regarding this issue MediaPlayer.setValue function.

MediaPlayer.setValue( )
It's not the right function for setting the volume (see the help).

To set the volume to maximum i used below code it's working.

// Get the AudioManager
AudioManager audioManager =
(AudioManager)this.getSystemService(Context.AUDIO_SERVICE);
// Set the volume of played media to maximum.
audioManager.setStreamVolume (
AudioManager.STREAM_MUSIC,
audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC),
0);

 Some of other methods are in TextToSpeech Class

setPitch (float pitch)

Sets the speech pitch for the TextToSpeech engine. This has no effect on any pre-recorded speech.

setSpeechRate (float speechRate)

Sets the speech rate. This has no effect on any pre-recorded speech.

setLanguage(Locale loc)

Sets the text-to-speech language. The TTS engine will try to use the closest match to the specified language as represented by the Locale, but there is no guarantee that the exact same Locale will be used. Use isLanguageAvailable(Locale) to check the level of support before choosing the language to use for the next utterances.

isSpeeking()

Checks whether the TTS engine is busy speaking.

synthesizeToFile (String text, HashMap<String, String> params, String filename)

Synthesizes the given text to a file using the specified parameters.

getLanguage ()

Returns a Locale instance describing the language currently being used by the TextToSpeech engine.
