Analysis of Android source code design patterns and practices (16)Chapter 2 visitor Mode Visitor mode is a behavior mode. It is the most complex of the 23 design modes. Although the frequency of use is not high, it does not mean that it can be ignored, it brings unexpected flexibility. Visitor mode, as the name implies, with this mode, you can add additional "visitors" without modifying the existing progr

Android Progress bar code and Progress bar refreshing Today I saw a discussion about the slow progress bar. The actual problem is that the program execution speed in the background is very fast, but the progress bar on the interface is relatively slow. To this end, a small experiment was conducted to increase the progress bar to 100% in one second (1%

Example: @SuppressLint("NewApi")@Overridepublic void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); The code above indicates that the lint check "NewApi" is disabled in the onCreate method, but the lint still checks other methods without the @ SuppressLint ("NewApi") Mark.Similar: @SuppressLint("ParserError")public

being decompiled: A) Minimize sensitive content in client code, such as the key of the encryption algorithm. It is impossible to avoid cracking at all. companies like Microsoft and Apple will also be cracked and jailbroken. We can only find ways to increase the difficulty of decompilation and the threshold for cracking. First, try to make sensitive content on the server rather than on the client. The key i

This problem occurs recently when an android application is used. The customer requires that the function be registered before it can be used, and the program itself is not used online. Therefore, the machine code registration mechanism should be added to the program. It is well known that android applications are developed based on Java. If no processing is per
