这次错误说明并不是所有没在manifest中添加权限的错误都会在错误提示中提示出来的

attempt to write a readonly database

错误是试图写数据到只读数据库

打开数据库的方法是这种

应该没错的

SQLiteDatabase db = SQLiteDatabase.openDatabase(Dir.dbPath, null,SQLiteDatabase.OPEN_READWRITE);

经过网上查找在论坛发现错误原因是没加权限

<span style="font-size:18px;"><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /></span>
