Android error MediaPlayer usage of media Player called in state *

With media Player, there are a few questions, remember


Usage is not said, when using the best reference to the MediaPlayer of this picture



The first error is media Player called in State 8

This is because there was no prepare before calling start, because I used the

MediaPlayer = mediaplayer.create (context, r.raw.notice);

To initialize the player, this interface illustrates

As long as a successful return to the player does not need to go to prepare, but I call stop and start many times later, resulting in the above error,

It can also be seen on the control chart that if you use stop when you pause, you must re-prepare before start or error media Player called in State 8

If pause is paused, the direct start can be used without prepare.


The second error is media Player called in State 0

This error is due to

public void Play () {try {mediaplayer.prepare ();} catch (IllegalStateException e) {e.printstacktrace ();}
Mediaplayer.start ();
}


Change it to the following.

public void Play () {try {mediaplayer.setonpreparedlistener (preparedlistener); Mediaplayer.prepareasync ();} catch ( IllegalStateException e) {//TODO auto-generated catch Blocke.printstacktrace ();}} Onpreparedlistener Preparedlistener = new Onpreparedlistener () {@Overridepublic void onprepared (MediaPlayer MP) { Mediaplayer.start ();}};


A look to understand, just at the beginning I finished prepare went directly to start, but this time may prepare has not succeeded, so reported the above error.
