判断手机是否安装某个应用的方法有很多，但是有的也存在问题，下面写一个项目里常用的，能用的：

/**
         * 判断手机是否安装某个应用
         * @param context
         * @param appPackageName  应用包名
         * @return   true：安装，false：未安装
         */
        public static boolean isApplicationAvilible(Context context, String appPackageName) {
            PackageManager packageManager = context.getPackageManager();// 获取packagemanager
            List<PackageInfo> pinfo = packageManager.getInstalledPackages(0);// 获取所有已安装程序的包信息
            if (pinfo != null) {
                for (int i = 0; i < pinfo.size(); i++) {
                    String pn = pinfo.get(i).packageName;
                    if (appPackageName.equals(pn)) {
                        return true;
                    }
                }
            }
            return false;
        }

下面这个方法在使用的时候有些情况下会报错：java.lang.RuntimeException: Package manager has died

/**
         * 判断手机是否安装某个应用
         * @param context
         * @param packageName  应用包名
         * @return   true：安装，false：未安装
         * 该方法容易报错：java.lang.RuntimeException: Package manager has died
         */
        public static boolean isAppInstallen(Context context ,String packageName){
            PackageManager pm = context.getPackageManager();
            boolean installed = false;
            try {
                    pm.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
                installed = true;
            } catch (PackageManager.NameNotFoundException e) {
                e.printStackTrace();
                installed = false;
            }
            return  installed;
     
        }
