I would like to delete the database file from the Android file system programatically? Can I have a shell script launch adb which in turns runs a shell script in the Android space to do the database deletion? Can I get this done from within a JUnit test case (with a system() call)?

如何在 Android 中删除整个数据库?我需要让整个事情消失，以便我可以测试数据库创建.我可以删除桌子，但这还不够.这是在模拟器中，而不是在手机上.

How do I delete an entire database in Android? I need to make the whole thing go away so I can test database creation. I can drop tables, but that's not enough. This is in the emulator, not on a phone.

推荐答案

一旦你有你的上下文并知道数据库的名称，使用:

Once you have your Context and know the name of the database, use:

context.deleteDatabase(DATABASE_NAME);

当这一行运行时，数据库应该被删除.

When this line gets run, the database should be deleted.
