######原始代码
String destFile = p.getImageDir() + now + ".png";
out = new FileOutputStream(file);
######产生原因
文件路径不存在时 输出流输出到文件时会报错
######更改建议
String destFile = p.getImageDir() + now + ".png";
File file = new File(destFile);
if(!file.getParentFile().exists()){
file.getParentFile().mkdirs();
}
out = new FileOutputStream(file);
