1.不要在UI线程里调用getReadableDatabase ()或者getWritableDatabase ()方法

    参见androidAPI文档如下:

    Create a helper object to create, open, and/or manage a database. This method always returns very quickly. The database is not actually created or opened until one of getWritableDatabase() or getReadableDatabase() is called.

    Like getWritableDatabase(), this method may take a long time to return, so you should not call it from the application main thread, including from ContentProvider.onCreate().

     Database upgrade may take a long time, you should not call this method from the application main thread, including from ContentProvider.onCreate().
