Android获取签名相同的软件列表(签名比对)

        try {
            PackageManager pmg = getPackageManager();

            List<ApplicationInfo> apps = pmg.getInstalledApplications(0);

            Signature ss1 = pmg.getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES).signatures[0];
            for (int i = 0; i < apps.size(); i++) {
                Signature ss = pmg.getPackageInfo(apps.get(i).packageName, PackageManager.GET_SIGNATURES).signatures[0];
                if (ss.equals(ss1)) {

                }
            }
        } catch (NameNotFoundException e) {
            e.printStackTrace();
