Android, in fact, the core is one: no matter how the upper layer of reinforcement, eventually loaded into the memory of the Dex is certainly not a reinforcement, so this dex is what we want, Ida is used here to dynamically debug the Dvmdexfileopenpartial function in libdvm.so to get the Dex content in memory, and it can also be obtained using Gdb+gdbserver, the interested classmate to search by themselves. Combined with the previous two articles, eve

Store these services in a hashmap in the form of key-value pairs. Users only need to rely on key to obtain the corresponding servicefetcher. The detailed service object is then obtained through the GetService function of the Servicefetcher object. When the first time is ac

Android design mode-decoration Mode 1. Definition: Attach additional responsibilities to an object dynamically keeping the same interface.Decoators provide a flexible alternative to subclassing for extending functionality. Dynamically extends the functions of an object without changing the original class file and using inheritance. It creates a packaging object,

Problem Description: the Android SDK Manager cannot download the update, or the update is very slow, or the list of packages to be installed is not displayed.

Find the file, we need to modify the file, some students may find that will not be able to modify the file, this may b

The Shared Runtime contains the Mono runtime and bcl,shared Platform contains specific assemblies for Android API levels:Replicating the 2 core components only needs to be done once, because it takes a very long time, but allows subsequent applications to run in debug mode. Finally, the applications we actually r

Factory mode is a typical decoupling mode, can reduce the coupling degree between the objects;4.4, the factory model relies on the abstract architecture, it is the task of the instantiation of the product to the implementation of the class completion, the scalability is better.4.5, can make the code structure clear, effectively package changes.4.6. Block specific product classes for callers. If you use Fac

popular, it is no longer just used in the push mail, more in our app.When we develop the applications that need to interact with the server, we basically need to get the server-side data, such as "earthquake emergency traffic" need to get the latest seismic information on the server. There are generally two ways to get information about updates on the server that are not timed: the first is the way the client uses pull, which is to get information from the server at a time and see if there is a
