SoundPool not playing sound (while MediaPlayer does)

阅读更多关于 SoundPool not playing sound (while MediaPlayer does)

问题 I am trying to play a sound in an app. However, using SoundPool I am unable to do so. The code is really simple and I don't see where it can fail. A similar code but using MediaPlayer does work, but I am interested in using SoundPool. SoundPool code: private void playSound2(){ SoundPool sp = new SoundPool.Builder().build(); int soundID = sp.load(MainActivity.this, R.raw.sound, 1); sp.play(soundID, 1, 1, 1, 0, 1); } Context: public void goButtonClick(View view){ Button goButton = findViewById

问题 I'm trying to have a SoundPool play while a view object is being clicked. I have successfully implemented it but found out that the sound of the click will lag. I've been researching on StackOverFlow and on the internet for solutions and the best solution seems to be to have the SoundPool on a separate Thread. I'm very new to the whole Thread thing and so I don't really know what to do at the moment. I have followed THIS guide on creating a SoundPool thread, however, I don't know how to

Android SoundPool 的简单使用

阅读更多关于 Android SoundPool 的简单使用

3 月，跳不动了？>>> 之前只知道Android中可以用MediapLayer播放音乐，原来今天才发现可以用SoundPool,用 SoundPool 可以播一些短的反应速度要求高的声音，比如游戏中的爆破声，而 MediapLayer 适合播放长点的。一般在玩游戏的时候，特别是在射击游戏中，经常会出现“突突突的射击”的声音，听起来好多声音连发的效果。其实实现起来是不难的，都知道，在Java中有线程池的概念，那么，类似的，在 Android 中，也存在 SoundPool 的概念。备注：声音池默认申请1M的内存空间，所以不适合加载大文件。 SoundPool载入音乐文件使用了独立的线程，不会阻塞UI主线程的操作。但是这里如果音效文件过大没有载入完成，我们调用play方法时可能产生严重的后果，这里Android SDK提供了一个SoundPool.OnLoadCompleteListener类来帮助我们了解媒体文件是否载入完成，我们重载 onLoadComplete(SoundPool soundPool, int sampleId, int status) 方法即可获得。从上面的onLoadComplete方法可以看出该类有很多参数，比如类似id，是的SoundPool在load时可以处理多个媒体一次初始化并放入内存中，这里效率比MediaPlayer高了很多。

Loading SoundPool with audio from APK Expansion file

问题 In the documentation it says: If you're using your expansion files to store media files, a ZIP file still allows you to use Android media playback calls that provide offset and length controls (such as MediaPlayer.setDataSource() and SoundPool.load()). I have 10 small .ogg files and I want to use SoundPool.load (FileDescriptor fd, long offset, long length, int priority) to load these audio files. I've written some code, but when I run it I get error message: "Unable to load sample: (null)" ,
