每当我的应用尝试发送意图邮寄任何邮件应用时，它都会崩溃。 有人可以帮我解决这个问题吗？
这是我的意图的xml代码：
Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setData(Uri.parse("mailto:"));
intent.setType("*/*");
intent.putExtra(Intent.EXTRA_EMAIL, "jainharshil670@yahoo.in");
intent.putExtra(Intent.EXTRA_SUBJECT, "My Coffee Order");
intent.putExtra(Intent.EXTRA_TEXT, priceMessage);
startActivity(intent);
应用程序在日志文件中提供的错误消息是：

以这种方式向您的清单添加活动：
<activity android:name=".AppPreferenceActivity" android:label="@string/app_name">
<intent-filter>
<action android:name="com.scytec.datamobile.vd.gui.android.AppPreferenceActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

line 2:++++execSync('powershell get-netipaddress '+ip)消除了您在setType()中的价值。相反，结合：
setData()成：
intent.setData(Uri.parse("mailto:"));
intent.setType("*/*");
intent.putExtra(Intent.EXTRA_EMAIL, "jainharshil670@yahoo.in");
（将intent.setDataAndType(Uri.parse("mailto:jainharshil670@yahoo.in"), "text/plain");
替换为text/plain中所含内容的实际MIME类型

这意味着android系统没有找到任何电子邮件发送活动来处理您创建的意图。确保您的设备中安装了电子邮件应用程序。
还可以使用以下代码发送电子邮件，
<% if @posts.present? %>
<% @posts.each do |post| %>
<%= link_to "#{post.title}", post_path(post) %>
<% end %>
<% else %>
<p> You don't have any post yet. Keep posting! </p>
<% end %>

我在发布这个问题之后就知道了。
当我看到行
时，我发现了它intent.setData(Uri.parse("mailto:"));
intent.setType("*/*");
然后我删除了： -
intent.setType("*/*");
然后一切都很好。
