android kitkat 中的短信发送问题

Question

我在三星设备中发送短信时经常遇到这个问题。

安卓版本 Android 4.0.3 - 4.0.4

这是我收到的错误报告

java.lang.RuntimeException: An error occured while executing doInBackground()

... 5 more

在第 87 行，我有这段代码

sms.sendTextMessage(destinationNumber, null, msg, sentPI, deliveredPI);

所有这些方法都在AsyncTask的doInBackground()方法中。

有人可以帮我吗？

*注意：我的应用在后台发送短信，它不是默认短信应用。

Answer 1

我猜这是由于文本的大小限制。最大允许字符数为 159。因此您必须将消息分成几部分并发送。

老兄，你得到 NullPointerException。好像您还没有初始化 sms 对象。 请检查..
