I hope you can get something after reading this article. Let's take a look at this "what are the interview questions for Android development programmers?"

1. What are the advantages and disadvantages of MVP mode?

Advantages of MVP mode:

Reduce coupling degree

The division of module responsibilities is obvious.

Conducive to test-driven development

Code reuse

Hidden data

Code flexibility

Disadvantages of MVP mode:

Because the rendering of the view is placed in Presenter, the interaction between the view and Presenter is too frequent. It is also important to understand that if Presenter renders the view too much, it tends to make it too closely related to a particular view. Once the view needs to be changed, then Presenter also needs to change

2. How to start an Activity when you start a service?

First define a service, then connect and bindservice or startService directly in the onCreate of activity.

3. What is the relationship of Activity,Intent,Service?

An Activity is usually a separate screen, and each Activity is implemented as a separate class, which inherits from the Activity base class. The Activity class displays the user interface made up of view controls and responds to the events of the view control.

The call to Intent is used to switch between schema screens.

Intent describes what the application wants to do.

The two most important parts of Intent data structure are the corresponding data of action and action, and one action corresponds to one action data.

Android Service is code that runs in the background and cannot interact with users. It can run in its own process or in the context of other application processes. It needs to be called through an Activity or other Context object.

Activity jumps to Activity,Activity and starts Service,Service to open Activity. Intent is required to indicate the intention of the jump, as well as pass parameters, and Intent is the bearer of signaling between these components.
