Android 获取手机中已安装apk文件信息

通过PackageManager可以获取手机端已安装的apk文件的信息：

写法一：

    @Deprecated
    public List<String> getAllApps() {
        List<String> packageList = new ArrayList<>();

        final PackageManager packageManager = mContext.getPackageManager();
        List<PackageInfo> resolveInfoList = packageManager.getInstalledPackages(0);
        Log.d("caowj", "全部的应用数量：" + resolveInfoList.size());
        for (PackageInfo info : resolveInfoList) {
//            if ((info.applicationInfo.flags & info.applicationInfo.FLAG_SYSTEM) <= 0) {
//                //非系统应用
//                packageList.add(info.packageName);
//            }

            packageList.add(info.packageName);
        }
        Log.d("caowj", "非系统应用数量：" + packageList.size());
        return packageList;
    }

            }
        }
        Log.d("caowj", "非系统应用数量：" + packageList.size());
        return packageList;
