android - soundpool 提示堆内存溢出

Question

我在广播中对收到短信进行判断,然后根据短信内容想要播放音频文件.
在使用mediaplayer是可以正常播放的,但是使用soundpool就无法播放了,
错误提示,

E/AudioCache: Heap size overflow! req size: 1052672, max size: 1048576

我的音频文件大小是100k,格式是mp3;
我的代码是

package com.aa.safe.safe.receiver;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.media.SoundPool;
import android.telephony.SmsMessage;
import android.util.Log;

import com.aa.safe.safe.R;

public class SmsBroadcast extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("SmsBroadcast", "onReceive: " + "进入了短信接受");
        Object[] pdus = (Object[]) intent.getExtras().get("pdus");
        for(Object obj:pdus){
            SmsMessage msg = SmsMessage.createFromPdu((byte[]) obj);
            String msgBody = msg.getMessageBody();

            if("#*location*#".equals(msgBody)) {
                Log.d("SmsBroadcast", "onReceive: location" );
                abortBroadcast();
            }else if("#*alarm*#".equals(msgBody)) {
                Log.d("SmsBroadcast", "onReceive: alarm" );
                final SoundPool sp = new SoundPool(1, AudioManager.STREAM_MUSIC,0);
                final int load = sp.load(context, R.raw.faka,1);
                sp.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {
                    @Override
                    public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
                        sp.play(load,1.0f,1.0f,0,1,1.5f);
                    }
                });
//                MediaPlayer mediaPlayer = MediaPlayer.create(context, R.raw.faka);
//                mediaPlayer.start();
                abortBroadcast();
            }else if("#*wipedata*#".equals(msgBody)) {
                Log.d("SmsBroadcast", "onReceive: wipedata" );
                abortBroadcast();
            }else if("#*lockscreen*#".equals(msgBody)) {
                Log.d("SmsBroadcast", "onReceive: lockscreen" );
                abortBroadcast();
            }
        }
    }
}

错误已经很明显了，播放的文件大小超过SoundPool所支持的内存限制的大小。SoundPool对内存是有限制的，它只支持小而急促的音频文件。你可以换个更小的音频文件试试。
