Android MediaPlayer Stop And Play


Answer :

You should use only one mediaplayer object

    public class PlayaudioActivity extends Activity {          private MediaPlayer mp;          /** Called when the activity is first created. */         @Override         public void onCreate(Bundle savedInstanceState) {             super.onCreate(savedInstanceState);             setContentView(R.layout.main);             Button b = (Button) findViewById(R.id.button1);             Button b2 = (Button) findViewById(R.id.button2);             final TextView t = (TextView) findViewById(R.id.textView1);              b.setOnClickListener(new View.OnClickListener() {                  @Override                 public void onClick(View v) {                     stopPlaying();                     mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.far);                     mp.start();                 }              });              b2.setOnClickListener(new View.OnClickListener() {                  @Override                 public void onClick(View v) {                     stopPlaying();                     mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.beet);                     mp.start();                 }             });         }          private void stopPlaying() {             if (mp != null) {                 mp.stop();                 mp.release();                 mp = null;            }         }     }

To stop the Media Player without the risk of an Illegal State Exception, you must do 

  try {         mp.reset();         mp.prepare();         mp.stop();         mp.release();         mp=null;        }   catch (Exception e)          {            e.printStackTrace();          }

rather than just 

try {        mp.stop();        mp.release();        mp=null;     }  catch (Exception e)      {       e.printStackTrace();     }

According to the MediaPlayer life cycle, which you can view in the Android API guide, I think that you have to call reset() instead of stop(), and after that prepare again the media player (use only one) to play the sound from the beginning. Take also into account that the sound may have finished. So I would also recommend to implement setOnCompletionListener() to make sure that if you try to play again the sound it doesn't fail.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
