Question

好的，我在这里有一个奇怪的错误，我无法弄清楚。我在android＆＃34; android.intent.action.SEND＆＃34;中与共享选项列表共享数据。

分享单张图片效果很好，但是当我尝试分享纯文本，例如＆＃34; asdfdgdsfsa＆＃34;时，该程序会抛出此错误

＆＃34; Java.Lang.RuntimeException：无法实例化活动 ComponentInfo {com.companyname.Revamp / Revamp.RecieveDataFromApp.RecieveDataFromApp}： java.lang.ClassNotFoundException：没找到类＆＃34; Revamp.RecieveDataFromApp.RecieveDataFromApp＆＃34;在路径上： DexPathList [[zip文件＆＃34; /data/app/com.companyname.Revamp-HFm6SmD1Y-A76OQwcwCXIA == / base.apk＆＃34]，nativeLibraryDirectories = [/数据/应用/ com.companyname.Revamp-HFm6SmD1Y-A76OQwcwCXIA == / lib中/ 86， /系统/假库， /data/app/com.companyname.Revamp-HFm6SmD1Y-A76OQwcwCXIA==/base.apk!/lib/x86， / system / lib，/ vendor / lib]]＆＃34;。

  protected override void OnCreate(Bundle bundle)
    {

        Intent intent = Intent;
        String action = Intent.Action;
        String type = intent.Type;

        if (Intent.ActionSend.Equals(action) && type != null)
        {
            // This is what we are trying to get working here. 
            if ("text/plain".Equals(type))
            {
                // Handle text being sent
                // ...
                // ...
                // ...     
            }
            else if (type.StartsWith("image/"))
            {
                // Handle single image being sent
                // ...
                // ...
                // ...    
            }
        }
        else if (Intent.ActionSendMultiple.Equals(action) && type != null)
        {
            //This works 
            if (type.StartsWith("image/"))
            {
                // Handle multiple images being sent
                // ...
                // ...
                // ...                        
            }
        }
        else
        {
            // Handle other intents, such as being started from the home screen                    
        }

        TabLayoutResource = Resource.Layout.Tabbar;
        ToolbarResource = Resource.Layout.Toolbar;

        base.OnCreate(bundle);

        global::Xamarin.Forms.Forms.Init(this, bundle);
        LoadApplication(new App());
    }

我已经测试了您的代码并重现了该问题。您可以尝试在代码中设置intent-filter，而不是AndroidManifest.xml 例如：

[Activity(Label = "RecieveDataFromApp", Icon = "@drawable/icon", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
[IntentFilter(new[] { Intent.ActionSend }, Categories = new[] { Intent.CategoryDefault }, DataMimeType = "image/*", Label = "RecieveDataFromApp")]
[IntentFilter(new[] { Intent.ActionSend }, Categories = new[] { Intent.CategoryDefault }, DataMimeType = "text/plain", Label = "RecieveDataFromApp")]
[IntentFilter(new[] { Intent.ActionSendMultiple }, Categories = new[] { Intent.CategoryDefault }, DataMimeType = "image/*", Label = "RecieveDataFromApp")]    
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
   ...
   ...
   ...
}

带有共享选项列表的纯文本会出错
