How to understand single (double) linked list, Trie tree and idx in heap?
Reprinted and modified on ACwing Questions In this chapter, we often see that y always uses the variable idx in implementing various data structures. What is the use of this variable? Why Linked List, Trie and Heap use idx to maintain this data structure, but Stack and Queue don’t use idx strong> instead of hh […]
[Solved] Code obfuscation solution, adapted to AndroidX
Obfuscation in android Studio is basically the operation of the Proguard-rules.pro file. The process of confusion is also regular. Below I will introduce the obfuscation process in several parts. (1) How to turn on confusion. (2) Obfuscated public parts. (3) Requires code that we don’t obfuscate. (4) Obfuscation of third-party Jar packages under libs. (5) […]
[Solved] [Problem solving] Solve the conflict between Androidx and other third-party libraries when compiling
The new project in Android Studio uses the Androidx library. If the old version of the Support library is included in the third-party library used at this time, a conflict error will be reported. `Your project has set `android.useAndroidX=true`, but configuration `:app:debugAnnotationProcessorClasspath` still contains legacy support libraries, which may cause runtime issues. This behavior will […]
