问题
I am working with an android media application for that i want play a sound file simultaneously for a specific period of time. So i've created a Class and i am using SoundPool and Thread concepts inside this class to play the sound but when i run my application it is going to an ANR state and showing a warning in log-cat
sample 2130968576 not READY
anyone please help me to fix this...
Class
package com.kodspider.funk;
import android.content.Context;
import android.media.AudioManager;
import android.media.SoundPool;
public class CustomPlayer implements Runnable{
int song_id;
long time;
int button_id;
Context ctx;
SoundPool soundpool;
public CustomPlayer(int s_id, long Time, Context ct){
song_id = load(ctx, s_id, 0);
time = Time;
ctx = ct;
}
public void run(){
long start = System.currentTimeMillis();
System.out.println("set_time:"+time+"Song_id:"+song_id+"current_time:"+start);
long end = start + time;
while (System.currentTimeMillis() < end){
//Initialization
soundpool = new SoundPool(8, AudioManager.STREAM_MUSIC, 0);
soundpool.play(song_id, 1.0f, 1.0f, 1, -1, 1.0f);
}
}
public int load (Context context, int resId, int priority){
return resId;
}
}

I'm doing something similar with my app Beat Shaker and I was having the same problem. I solved it using the onLoadCompleteListener:
// Sound pool new instance
SoundPool spool = new SoundPool(3, AudioManager.STREAM_MUSIC, 0);
// Sound pool on load complete listener
spool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
@Override
public void onLoadComplete(SoundPool soundPool, int sampleId,
int status) {
Log.i("OnLoadCompleteListener","Sound "+sampleId+" loaded.");
boolean loaded = true;
}
});
// Load the sample IDs
int soundId = new int[3];
soundId[0] = spool.load(this, R.raw.sound1, 1);
soundId[1] = spool.load(this, R.raw.sound2, 1);
soundId[2] = spool.load(this, R.raw.sound3, 1);
Later before playing the sound you can check if it is properly loaded using the boolean "loaded".

You need to first load() your sounds. This loads them into memory ready for play(). This returns an id that you will need to store and pass to play()
From the SoundPool docs:
Let's examine a typical use case: A game consists of several levels of play. For each level, there is a set of unique sounds that are used only by that level. In this case, the game logic should create a new SoundPool object when the first level is loaded. The level data itself might contain the list of sounds to be used by this level. The loading logic iterates through the list of sounds calling the appropriate SoundPool.load() function. This should typically be done early in the process to allow time for decompressing the audio to raw PCM format before they are needed for playback.

Have a look at the SoundPool section in this example: http://www.vogella.com/articles/AndroidMedia/
