Before is to do domestic application development, has not used foreign three-party login, such as Google login, Facebok login, recently participated in an overseas payment related projects, survey of Google Login and Facebook login, in fact, after the survey felt is also very simple,　　　　In particular, Facebook login, with the domestic three-party login integration almost no difference. Let's talk about the Facebok login integration process: First you

0x01 Android Intents with Chrome Android has a feature that few people know can send intent via a Web page to launch apps.

If all applications have version updates, how can they be updated? Today, we will introduce the entire process of automatic application updates. The procedure for automatically updating a program is roughly as follows: Program startup --> timely background check for updates ---> link remote server --> get new version information --> Compare the current version --> if (updated) --> display the update prompt dialog box and display the updated content --> submit and select. Below is my demo. You

new SocialLoginImpl());// 指定使用的具体实现loginMgr.useThis(clzKey);To make it simpler, the process is encapsulated in a function, and the code used is finally simplified to:// 一行代码搞定！这个函数封装了上述所有的代码。LoginSDKManager.getInstance().addAndUse(new SocialLoginImpl()) ;With these steps, the login system is injected into the micro-Community SDK. When a friend Alliance Micro community needs to log in, the micro-Community SDK will take the user-specified login implementation via Loginsdkmanager's Getcurrentimpl (

methods that enable activity and fragment to easily interact with the rest API's data. These methods use URLConnection and Asynctask to execute a network request within a separate thread, and then return the result to the activity through a callback.In the same way, Cacheprovider contains methods for retrieving and storing data from sharedpreferences and SQLite databases. Also use callbacks to return the results back to the activity.Problems that exist:The main problem with this structure is th

above configuration, the HTTP traffic in the app can go directly to the Burp suite: Four, Summary: Android app is more of HTTP communication, a small number of HTTPS, which is also the status of domestic network security problems. After all, unencrypted HTTP communications save bandwidth and system resources, more people directly using non-SSL or TLS encryp

method.Iii. Overview of the implementation methodsOne might think that if you could download a DLL-like file or a jar package like any other platform, it would automatically recognize and load the feature? Unfortunately, the Android platform is not allowed to directly load the jar package, the author did not think of a similar approach. So, to do this, you still have to load it in a standalone apk. And the first way is different, from the design poin

provided bySecurity Inspection PlatformIt provides the convenience for the app's security vulnerability analysis. Now with love encryption as an example, the online vulnerability detection for simple analysis:App developers only need to upload an APK package in the Love encryption security detection platform, can analyze the vulnerability, detect the content: Dex file detection apk, resource files, so library files, whether the main files are encrypt

In Android, how to implement custom broadcast can only receive the specified app, androidapp I went to the interview again today, but I won't talk about the specific company, because I noted the names of those companies in my previous blog, as a result, people sent me a private message saying that I leaked their questions. Okay, I am wrong... In fact, when we are at work, we can face each other in our free

configuration, HTTP traffic in the app can go straight to Burp suite:Iv. Summary:Android app is more in the use of HTTP communication, a few of the use of HTTPS, which is also the status of domestic network security issues. After all, unencrypted HTTP communication saves bandwidth and system resources, and more people directly use non-SSL or TLS-encrypted HTTP communication, which is why network sniffing i

Use android studio to detect app Memory leakage [reprinted] And androidapp In Android development, various memory leaks are inevitable. If you do not find and handle the vulnerabilities in time, the larger the memory usage, and various strange crash may occur due to memory leaks, the APP may even crash due to insuffici

more perfectly.One thing to be aware of is that Coordinatorlayout does not know the internal workings of Floatingactionbutton or appbarlayout, It simply provides an additional API in the form of Coordinator.behavior, which enables child view to better control touch events and gestures, and to declare dependencies between them, and receive callbacks through Ondependentviewchanged ().You can use Coordinatorlayout.defaultbehavior (your View.Behavior.class) annotation or use app:layout_behavior= in

My friend recommended me to go to the Huawei terminal in Xi'an last time. Then HR called me and asked me if I had any Android development experience. I said no, and I was not given an interview. I am not doing anything here. Why can't I do anything without relevant experience? Of course, I admit that I don't have any experience. When I first started working, There will be differences, but is experience omnipotent? Is it so difficult to cross-border?

division of required functions, and the rational allocation of teams. Efficient Production and fast iteration are the survival of mobile projects. Android Testing Mobile development requires logical testing to ensure quality output. In the design of the project framework, the simple mvc mode is not conducive to interface testing if the view and model are mixed with the business logic. Therefore, in subsequ
