检测是否安装App
/**
* 检索是否有对应app
*/
fun isApp(packageName: String?): Boolean {
//获取packagemanager

//获取所有已安装程序的包信息
val packageInfos = packageManager?.getInstalledPackages(0)

val packageNames: MutableList = ArrayList()
//从pinfo中将包名字逐一取出，压入pName list中
if (packageInfos !=null) {
for (iin packageInfos.indices) {
val packName =packageInfos[i].packageName
packageNames.add(packName)
}
}
//判断packageNames中是否有目标程序的包名，有TRUE，没有FALSE
return packageNames.contains(packageName)
}
