XYLibrary笔记八：PackageManager基础
一.代码位置（点击末尾阅读原文）
- xlib-Application
- XTester-packagemanger
二.引用方式
将JitPack存储库添加到您的构建文件中 将其添加到存储库末尾的root build.gradle中：
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}添加依赖项
dependencies {
...
implementation 'com.github.itemuse:XLib:Tag'
}初始化 Application中init
import cn.xy.library.XApp;
...
@Override
public void onCreate() {
super.onCreate();
XApp.init(this);
}AndroidManifest.xml中添加UID
android:sharedUserId="android.uid.system"三.几个方法
