在安装之前，您无法轻松获取下载的 APK 文件的版本。
话虽如此，您可以解压缩 APK 文件（它只是一个 zip 文件）并解析 AndroidManifest.xml 以获取版本代码的值。由于您提取的 AndroidManifest.xml 是一个二进制文件，因此您需要编写一些代码来解析它。它不像检查纯文本文件那么简单。

PackageManager manager = this.getPackageManager();
PackageInfo info = manager.getPackageInfo("com.whatsapp", 0);
String packageName = info.packageName;
int versionCode = info.versionCode;
String versionName = info.versionName;
Replace com.whatsapp with your package name.
