HCE mode allows the software to simulate smart cards and generate electronic virtual smart cards .HCE (host-based card Emulation) is an analog smart card software that exists as software in Android (for example: APK). HCE is characterized by analog intelligent IC Card (ISO 7816-4), can be used in finance, transportatio

First, prefaceToday we opened the Android system article, in fact, have always wanted to get, but has not been too much in-depth understanding, and recently took this piece out of a good look, so want to comb a bit, to see the android in this piece of knowledge, First of all, let's take a look at this: the concept of smart pointers in

In the previous article, we analyzed the strong pointer sp in the Android smart pointer. In this article, we will analyze the weak pointer wp. Why do we need a weak pointer wp? Consider the following scenario: CParent and CChild. A smart pointer points to a CChild object in the CParent class, and a smart pointer points

Ultra-smart Android data transmission method and android Data Transmission In Android, data transmission between activities is somewhat complicated. For example, when a complex object is passed through Intent and Bundle, it must be a class that implements the Serializable interface, this makes data transmission between

incorrectly, Android provides us with smart pointers, defined in the RefBase.h and StrongPointer.h files in the Frameworks/rs/cpp/util directory.Android smart pointer is a template class, also divided into strong pointer sp and weak pointer WP. The strong pointer SP is defined as follows: 62template66-71 rows, 5 SP constructors are defined.73 rows, defines the S

Design of smart pointersA very important difference between Java and C ++ is that Java does not have the "Pointer" concept, but does not. Pointers are used in internal use, but hidden, pa

The Android mobile operating system is an open-source operating system. The open source code of various functions is stored in a specific folder. We can modify the source code to easily complete the required functions. Here we will take a look at the Android smart pointer source code interpretation and application methods. Introduction to the callback method of

Android mobile OS is an open source operating system. Then in the specific folder will be stored in a variety of related functions of open source code. We can easily complete the functions we need when we use these source code to make corresponding changes. Here, let's take a look at Android intelligencePointers to the relevant source code interpretation and Application methods.In the

Wit Cloud currently offers 3 sets of Sdk:ios platform native SDK, Android platform native SDK, Apicloud cross-platform SDK. Developers can choose their own according to the project, where the Apicloud version SDK can be developed at once with H5 technology, with iOS and Android two plat
