我知道呼入短信可以容易地使用广播reciever截获。但我没有看到任何方式来拦截传出的短信。如何才能做到这一点？但是有一个办法做到这一点。因为很多第三方应用程序读取传入和传出的短信。

I know that an incoming sms can be easily intercepted using a broadcast reciever. But I did not see any way to intercept an outgoing sms. How can this be done? But there is a way to do this.. Because many third party applications read both incoming and outgoing sms.

推荐答案

您将不得不做这样的事情：

You will have to do something like this:

缓存所有消息的散$ C $手机基于C 注册的内容观察员了解内容：//短信 在的onChange 方式观测，enumrate所有消息以检查它是否在缓存中，如果不是，该消息被发送出去刚才。 Cache all messages's hash code on the phone Register an content observer for content://sms In onChange method of observer, enumrate all messages to check if it is in cache, if not, the message is sent out just now.

编辑：MD5法 可以采取（抵达日期+消息）文本，以获得一个唯一的MD5输出。

md5 method You can take the (arrival date + message) text to get a unique md5 output.

private String md5(String in) {
    MessageDigest digest;
    try {
        digest = MessageDigest.getInstance("MD5");
        digest.reset();        
        digest.update(in.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) { e.printStackTrace(); }
    return null;
}
