我有一个sqlite数据库文件,但是我无法读写这个数据库文件。 我正在使用以下代码:
fileIsExists = new File(Environment.getExternalStorageDirectory()
+ "/bbmp/bbmp2.sqlite");
if (fileIsExists.exists()) {
db = SQLiteDatabase.openDatabase(fileIsExists.toString(), null,
SQLiteDatabase.OPEN_READWRITE);
}
这会抛出以下错误:

10-01 17:09:17.374: E/Database(9216): Failed to setLocale() when constructing, closing the database
