java - Issue Preparing MediaPlayer to play custom file -


So basically everything works fine when I'm playing with the application in the audio / res / raw folder from the file However, when I want to select a file from a user, I have trouble, the user should have a data source for the media player set on the URI of the chosen file for the object. Then the player to start with the new data source and play it. My error comes when the game system is implemented. It says that I am asking to play in an illegal state (i had not already prepared the player), but it is definitely ready what is happening and how can I fix it?

Please help!

Invited method to choose a file: 

  Select Public Zero file () {intent to; Intent = new intent (); Intent.setAction (Intent.ACTION_GET_CONTENT); Intent.setType ("audio / mpeg"); StartActivityForResult (Intent.createChooser (intent, selected audio video path), 1); }   
 Activity result method:  
  Public zero activity dissection on @Override (int requestcode, integer result code, intent data) {super.onActivityResult (requestCode, resultCode , Information); If (resultcode! = RESULT_CANCELED) {If (requestcode == 1 & amp; amp; resultcode == activity. RESULT_OK) {If ((data! = Null) & amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; Data; getData )! = Null)) {UserChosenFilePath = data .getData (); setSongToUserPick (); }}}}   
 setSongToUserPick method:  
  public zero set SONGToUserPick () {stop (); CurrentAudioPath = userChosenFilePath; InitializePlayer (); Prevented = false; Play(); }   
 Stop method:  
  public zero-stop () {isPlaying = false; Prevented = true; PlayPauseButton.setText ("Play"); Player.stop (); Player.release (); }   
 Start the player method:  
  Public Zero initial player () {nowPlayingView.setText (filenameNumber .getBaseName (currentAudioPath.toString ()); Try {Player.setDataSource (thisContext, currentAudioPath); } Hold (illegal illegal concept | security access | illegalstateexception | iOException e) {e.printStackTrace (); } {Try Player.prepare ()}} (IllegalStateException | IOException e) {e.printStackTrace (); }}   
 And finally, play method:  
  public zero play (if {iprpayer} {isPlaying = true; PlayPauseButton.setText ("Pause"); Player.start (); } And {System.out.println ("Aha broke."); }}    
 
 
 Use this if it helps you:  < Pre>  if (current audiopath! = Null) player = mediaplayer credits (this context, uri.from (current audio path.stustring ());

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
