但是只有在一台4.4版本和5.1版本的机器上有这个问题，其他的机器都没问题，这是为什么

Answer 1

是不是手机的CPU架构不一样，没有对应的.so文件加载

Answer 2

path的获取方式不行，或者该型号手机不支持这种方式创建文件
 /**
     * 创建File对象，用于存储照片
     */    public File saveFile(String filename) {
        String storageState = Environment.getExternalStorageState();// 获取sd卡的状态
        if (Environment.MEDIA_MOUNTED.equals(storageState)) {// 如果已挂载状态
            //存储在SD卡文件夹image下
            dir = new File(Environment.getExternalStorageDirectory().getPath() + "/fsh_image");
            if (!dir.exists()) {
                dir.mkdirs();
            }            file = new File(Environment.getExternalStorageDirectory().getPath() + "/fsh_image/" + filename + ".jpg");
