Question

我在发送短信时大部分时间都在三星设备上遇到这个问题。

Android版 Android 4.0.3 - 4.0.4

这是我的错误报告

... 5 more

在第87行，我有这段代码

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

并且所有这些方法都在AsyncTask＆＃39; doInBackground()方法内。

有人可以帮我吗？

*注意：我的应用程序在后台发送短信，并且它不是默认的短信应用程序。

Answer 1

我想这是因为文字超出限制。允许的最大字符数为159.因此，您必须将消息分成几部分并发送。
