推荐答案
如果你计划的数据存储的MB，然后尝试使用SD卡，以避免填满建成尤其是在G1的手机往往是有限的存储空间。
If you are planning to store MBs of data then try to use the sdcard to avoid filling the often limited storage built into the phone especially on the G1.
如果你在手机上存储数据，每个应用程序都有它的时候卸载应用程序也将被删除其自身的存储区域。
If you do store data on the phone, each app has its own storage area which will also be deleted when the application is uninstalled.

有关缓存的文件，您可以使用 文件cacheDir = getCacheDir（）; 返回的路径，在文件系统中的特殊应用缓存目录。这些文件将是那些获得了第一个删除的设备在运行时存储时。
For cached files you can use File cacheDir = getCacheDir(); which returns the path to the application specific cache directory on the filesystem. These files will be ones that get deleted first when the device runs low on storage.
