尝试发送MMS时出现以下错误（我抑制了列表中建议的用于编写MMS的应用程序活动），并且代码看起来像
Uri path = Uri.parse("file:///sdcard//page.jpg");
Intent intent = new Intent(Intent.ACTION_SEND, path);
intent.putExtra("address", “<<phone number>>”);
intent.putExtra("subject", "dfsdfsdfds");
intent.putExtra("sms_body", "hello");
intent.setClassName(
"com.android.mms",
"com.android.mms.ui.ComposeMessageActivity"
);
intent.putExtra(Intent.EXTRA_STREAM, path);
intent.setType("image/*");
startActivity(intent);
设备：索尼Xperia
SDK版本：2.1

请帮我吗？
最佳答案
问题是空指针，如
java.lang.NullPointerException
从您发布的代码看来，路径是问题所在。它正在尝试从堆栈中基于URI设置附件。我怀疑它是否根据您的评论特定于设备。我认为问题仅仅是SDCard上没有“ Page.jpg”。
