有没有办法知道我的Android应用程序更新是手动更新还是自动更新到google play商店？

import android.content.Context;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;

public class UpdateChecker {
    public static boolean isManualUpdate(Context context) {
        try {
            PackageManager packageManager = context.getPackageManager();
            PackageInfo packageInfo = packageManager.getPackageInfo(context.getPackageName(), 0);
            int flags = packageInfo.applicationInfo.flags;
            return (flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0;
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        return false;
    }
}
