播放铃声时出现java.io.FileNotFoundException

如何解决播放铃声时出现java.io.FileNotFoundException

我想播放来电铃声。我确实喜欢下面的内容，

Uri defaultringtoneUri = ringtoneManager.getDefaultUri(ringtoneManager.TYPE_ringtone);
            if(currentringtonePlayer != null ){
                stopringtonePlayer();
            }
            currentringtonePlayer = new MediaPlayer();
            currentringtonePlayer.setDataSource(this,defaultringtoneUri);
            currentringtonePlayer.setLooping(true);
            currentringtonePlayer.prepare();
            currentringtonePlayer.start();

使用此代码播放铃声。但我得到了以下例外，

在我的情况下播放铃声。尽管我得到了这个例外。有人知道为什么会这样吗？提前致谢

解决方法

如何使用 getActualDefaultRingtoneUri

Uri defaultRingToneUri = RingtoneManager.getActualDefaultRingtoneUri(mContext,RingtoneManager.TYPE_RINGTONE);
