如何以编程方式读取我的Android apk构建时的日期？

import java.util.jar.JarEntry;
import java.util.jar.JarFile;
import java.util.zip.ZipEntry;

String apkPath = "your_apk_path"; // 替换为你的APK文件路径

try {
    JarFile jarFile = new JarFile(apkPath);
    ZipEntry zipEntry = jarFile.getEntry("classes.dex");
    long timestamp = zipEntry.getTime();

    // 将时间戳转换为日期格式
    Date buildDate = new Date(timestamp);
    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    String buildDateString = dateFormat.format(buildDate);

    System.out.println("APK构建日期：" + buildDateString);

    jarFile.close();
} catch (IOException e) {
    e.printStackTrace();
}
