二、判斷是否安裝某個軟件

/*** 判斷是否安裝某個軟件*/ fun isAvilible(context: Context, packageName: String): Boolean {//獲取packagemanagerval packageManager = context.packageManager//獲取所有已安裝程序的包信息val packages = packageManager.getInstalledPackages(0)//用于存儲所有已安裝程序的包名val arrayList = ArrayList<String>()//從pinfo中將包名字逐一取出，壓入pName list中if (packages != null) {for (p: PackageInfo in packages) {val p = p.packageNamearrayList.add(p)}}//判斷packageNames中是否有目標程序的包名，有TRUE，沒有FALSEreturn arrayList.contains(packageName); }
