使用 com.android.mms.ui.ComposeMessageActivity 发送彩信时出错

Question

当我尝试发送彩信时出现以下错误（我正在抑制用于编写彩信的建议应用程序活动列表），并且我的代码类似于

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：Sony Xperia SDK版本：2.1

请帮我解决这个问题？

Answer 1

问题是空指针，如

java.lang.NullPointerException

您发布的代码所示，看起来路径是问题所在。从您的堆栈中，它尝试根据 URI 设置附件。根据您的评论，我怀疑它是特定于设备的。我认为问题很简单，“Page.jpg”不在 SDCard 上。
