Android擷取apk程式簽名資訊程式碼範例_Android

複製代碼 代碼如下:

這是擷取apk包的簽名資訊
private String getSign(Context context) {
  PackageManager pm = context.getPackageManager();
  List<PackageInfo> apps = pm.getInstalledPackages(PackageManager.GET_SIGNATURES);
  Iterator<PackageInfo> iter = apps.iterator();
  while(iter.hasNext()) {
       PackageInfo packageinfo = iter.next();
       String packageName = packageinfo.packageName;

       return packageinfo.signatures[0].toCharsString();
       if (packageName.equals(instance.getPackageName())) {
          MediaApplication.logD(DownloadApk.class, packageinfo.signatures[0].toCharsString());
          return packageinfo.signatures[0].toCharsString();
       }
}
  return null;
}

返回的簽名資訊結果為很長的一串資料
