问题描述
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;/** * Created by the18 on 2016/11/19 0019. */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(); }} }}
问题解答
回答1：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。
