我曾尝试使用这一法典,但我却在任满例外。
FileInputStream fis = soundFile.createInputStream();
我增加了许可,但错误仍然存在?

如果您的法典与《刑法》相同的话。
try {
soundFile= mCr.openAssetFileDescriptor(mUri, "r");
} catch (FileNotFoundException e) {
soundFile=null;
}
try {
byte[] readData = new byte[1024];
FileInputStream fis = soundFile.createInputStream();
那么,可能发生的情况是:
mCr.openAssetFileDescriptor(mUri, "r");
要么放弃,要么引起例外。
我要:
(1) 添加一些标识,以准确追踪问题所在之处
(2) 检查你是否获得所有许可
3) 检查你试图打开的档案存放在正确的地点
if that fails come back here with some logs and we ll help more ;)
