1.cache.txt: open failed: EROFS (Read-only file system)
- 原因:
ObjectOutputStream outputStream = new ObjectOutputStream(new FileOutputStream("test.txt"));
现在有些手机不允许我们直接向sd card上写东西,因此做如下修改:
String fname = Environment.getExternalStorageDirectory() + "/test.txt";
ObjectOutputStream outputStream = new ObjectOutputStream(new FileOutputStream(fname));
