您可以使用MD5、SHA-1、SHA-256等哈希算法来为apk生成摘要。以下是生成SHA-256摘要的示例代码： ```java import java.io.FileInputStream; import java.security.MessageDigest; public class ApkDigest { public static void main(String[] args) { try { MessageDigest digest = MessageDigest.getInstance("SHA-256"); FileInputStream fis = new FileInputStream("jk_1.0.2_sign.apk"); byte[] byteArray = new byte[1024]; int bytesCount = 0; while ((bytesCount = fis.read(byteArray)) != -1) { digest.update(byteArray, 0, bytesCount); } fis.close(); byte[] bytes = digest.digest(); StringBuilder sb = new StringBuilder(); for (byte aByte : bytes) { sb.append(Integer.toString((aByte & 0xff) + 0x100, 16).substring(1)); } String hash = sb.toString(); System.out.println("SHA-256 Digest: " + hash); } catch (Exception e) { e.printStackTrace(); } } } ``` 您可以使用上述代码在您的Java环境中生成apk文件的SHA-256摘要。请确保将apk文件的路径更改为您的实际路径，运行代码后会打印出apk文件的SHA-256摘要。
