创建数据库Android的许可 [英] Android permission of creating database
问题描述
您好我在android系统中创建SQLite数据库的一些问题。
Hi I have some problems in creating the sqlite database in android.
一切正常在模拟器上，我可以创建数据库。但它不实际的机器上工作。当我试图调试我的手机上的应用程序，它只是无法创建数据库。
Everything is ok on the emulator, I can create the database. But it doesn't work on the actually machine. When I tried to debug the application on my phone, it just failed to create the database.
因此，谁能告诉我发生了什么事？是否有任何特殊的权限，我需要在manifest文件中添加？我已经试过ACCESS_CHECKIN_PROPERTIES或WRITE_EXTERNAL_STORAGE，但仍无法得到数据库。
So can anyone tell my what happened? Is there any special permission I need to add in the Manifest file? I've tried ACCESS_CHECKIN_PROPERTIES or WRITE_EXTERNAL_STORAGE, but still cannot get the database.
顺便说一句，就是自定义数据库只能存储在SD卡，但根目录？
By the way, is the custom database can only be stored in the sd card but the root directory?
非常感谢你！
推荐答案
如果没有错误的任何反馈，这是不可能告诉你什么是错在你的code。不过，我可以告诉你，你做的不可以需要 ACCESS_CHECKIN_PROPERTIES 使用自己的数据库。你不应该需要 WRITE_EXTERNAL_STORAGE 或者，除非您要访问的SD卡。
Without any feedback in the error, it is impossible to tell you what's wrong in your code. Nevertheless, I can tell you that you do not need ACCESS_CHECKIN_PROPERTIES for using your own database. You should not need WRITE_EXTERNAL_STORAGE either unless you are trying to access the sdcard.
该数据库默认保存在您的应用程序文件夹的子文件夹在内部存储，即：
The databases are stored by default in a subfolder of your app folder in the internal storage, i.e.:
/data/data/YOUR_APP/databases/YOUR_DATABASAE.db
如果你这样做，一个物理设备上它必须虽然扎根。
If you do that on a physical device it has to be rooted though.
