在android中尝试md5字符串时遇到问题

在Android上，我尝试md5字符串时出现以下错误：

"Performing stop of activity that is not resumed"

我需要将md5附加到URL

请帮忙

//md5代码

信息摘要

    try {
        digest = MessageDigest.getInstance("MD5");
        digest.reset();
        digest.update(text.getBytes());
        byte[] a = digest.digest();
        int len = a.length;
        StringBuilder sb = new StringBuilder(len << 1);
        for (int i = 0; i < len; i++) {
            sb.append(Character.forDigit((a[i] & 0xf0) >> 4, 16));
            sb.append(Character.forDigit(a[i] & 0x0f, 16));
        }
        return sb.toString();
    } catch (NoSuchAlgorithmException e) {

尝试使用此静态函数：

 public static final String md5(final String toEncrypt) {
    try {
        final MessageDigest digest = MessageDigest.getInstance("md5");
        digest.update(toEncrypt.getBytes());
        final byte[] bytes = digest.digest();
        final StringBuilder sb = new StringBuilder();
        for (int i = 0; i < bytes.length; i++) {
            sb.append(String.format("%02X", bytes[i]));
        }
        return sb.toString().toLowerCase();
    } catch (Exception exc) {
        return ""; // Impossibru!
    }
}

你能出示你的密码吗？我已经在用这个了。我的问题是，当我这样做时，会得到上面提到的错误。执行在该lineCare处停止，向我们展示如何调用md5函数并将其附加到URL？encryptedTaskId=MDConversion.MD5taskId；totalUrl=baseUrl+&access\u令牌=+accessToken+&id=+EncryptedTaskKid；totalUrl=baseUrl+？访问令牌=+accessToken+&id=+EncryptedTaskKid；–

 public static final String md5(final String toEncrypt) {
    try {
        final MessageDigest digest = MessageDigest.getInstance("md5");
        digest.update(toEncrypt.getBytes());
        final byte[] bytes = digest.digest();
        final StringBuilder sb = new StringBuilder();
        for (int i = 0; i < bytes.length; i++) {
            sb.append(String.format("%02X", bytes[i]));
        }
        return sb.toString().toLowerCase();
    } catch (Exception exc) {
        return ""; // Impossibru!
    }
