About the 9015 null pointer in the bmob backend cloud service platform, I checked it online. The reason is very simple, that is, it does not operate according to the official documents. Although the data can still be transmitted normally, it is still annoying to open the app with a prompt pop-up window.

Solution:

Directly open androidmanifest.xml and add two lines of code

        <provider
            android:name="cn.bmob.v3.util.BmobContentProvider"
            android:authorities="com.example.login.BmobContentProvider"/>

If I can help you, just give me a favor!!!   Thank you from the majority of hard pressed programmers!
