在 Xamarin.Forms 中创建默认短信应用
Creating Default SMS App in Xamarin.Forms
我正在 Xamarin 中开发一个短信应用程序，它应该是默认短信，我注册了短信接收器 class，
但是当设备收到消息时出现此错误。
Java.Lang.RuntimeException: 'Unable to instantiate receivercom.companyName.MySmsApp.DroidSmsReceiver: java.lang.ClassNotFoundException:Didn't find class "com.companyName.MySmsApp.DroidSmsReceiver" on path:DexPathList[[zip file "/data/app/com.companyName.MySmsApp-NaDrepA_GVue_nq4DxzmqA==/base.apk"],nativeLibraryDirectories=[/data/app/com.companyName.MySmsApp-NaDrepA_GVue_nq4DxzmqA==/lib/x86, /data/app/com.companyName.MySmsApp-NaDrepA_GVue_nq4DxzmqA==/base.apk!/lib/x86, /system/lib]]'

</intent-filter></receiver>
我的接收器，位于：MySmsApp.Droid
[BroadcastReceiver(Enabled = true, Exported = true)]
[IntentFilter(new[] { "android.provider.Telephony.SMS_RECEIVED" })]
//[IntentFilter(new[] { "android.provider.Telephony.SMS_DELIVER" })]
public class DroidSmsReceiver : BroadcastReceiver
{
//private const string IntentAction = "android.provider.Telephony.SMS_RECEIVED";
protected string address, message = "";
public override void OnReceive(Context context, Intent intent)
{
//message received
}
}
我也在MainActivity.cs
注册了接收器
RegisterReceiver(new DroidSmsReceiver(), new IntentFilter("android.provider.Telephony.SMS_DELIVER"));
提前谢谢大家。
您想在 xamarin 表单中实现类似 GIF 的结果吗？
如果是这样，我使用依赖服务来实现它。
首先，我在PCL
中创建了一个界面
public interface ISmsReader
{
void GetSmsInbox();
}
您可以在 PCL MainPage.xaml.cs.
中使用它
public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
MessagingCenter.Subscribe<List<string>>(this, "MyMessage", (expense) =>
{
List<string> mylist= expense as List<string>;
string allText= "";
foreach (string item in mylist)
{
allText += item+" ";
}
editorSms.Text = allText;
});
}
private void Button_Clicked(object sender, EventArgs e)
{
Xamarin.Forms.DependencyService.Get<ISmsReader>().GetSmsInbox();
}
}
这是我的 MainPage.xaml.
<StackLayout>
<Button Text="open broadcase" Clicked="Button_Clicked"/>
<Label x:Name="editorSms"/>
</StackLayout>
然后，在xxxx.Droidfolder.Note中实现这个接口：你的new IntentFilter("android.provider.Telephony.SMS_DELIVER")IntentFilter在你的MainActivity.cs中是错误的，应该是android.provider.Telephony.SMS_RECEIVED
[assembly: Xamarin.Forms.Dependency(typeof(MySmsReader))]
namespace ScanDemo.Droid
{
public class MySmsReader : ISmsReader
{
public void GetSmsInbox()
{
IntentFilter filter = new IntentFilter();
filter.AddAction("android.provider.Telephony.SMS_RECEIVED");
SmsBroadcastRceiver receiver = new SmsBroadcastRceiver();
Application.Context.RegisterReceiver(receiver, filter);
}
}
}
然后，这是我关于 SmsBroadcastRceiver 的代码。
[BroadcastReceiver(Enabled = true, Exported = true)]
[IntentFilter(new[] { "android.provider.Telephony.SMS_RECEIVED" })]
public class SmsBroadcastRceiver : BroadcastReceiver
{
public SmsBroadcastRceiver()
{
}
public override void OnReceive(Context context, Intent intent)
{
var msgs = Telephony.Sms.Intents.GetMessagesFromIntent(intent);
List<string> msgList = new List<string>();
foreach (var msg in msgs)
{
msgList.Add(msg.DisplayMessageBody);
}
MessagingCenter.Send<List<string>>(msgList, "MyMessage");
}
}
}
如果在SmsBroadcastRceiverclass上面设置了属性，则不需要在AndroidManifest中声明。
这是我的demo（我没有实现运行时权限，如果你测试我的demo，你应该手动添加权限）。

====更新====
这是我的 运行 GIF（将消息设置为已读）。
如果您想将消息设置为已读，首先，我们应该将我的应用程序设置为默认短信应用程序。
我们必须执行以下步骤（如果缺少其中一项，则无法执行）。
在广播接收器中，包括 SMS_DELIVER_ACTION ("android.provider.Telephony.SMS_DELIVER") 的意图过滤器。广播接收器还必须需要 BROADCAST_SMS 权限。这允许您的应用程序直接接收传入的 SMS 消息。
在广播接收器中，包含 MIME 类型 "application/vnd.wap.mms-message" 的 WAP_PUSH_DELIVER_ACTION ("android.provider.Telephony.WAP_PUSH_DELIVER") 的意图过滤器。广播接收器还必须需要 BROADCAST_WAP_PUSH 权限。这允许您的应用程序直接接收传入的彩信。
在您传递新消息的 activity 中，包括一个针对 ACTION_SENDTO ("android.intent.action.SENDTO") 的意图过滤器，其中包含模式、sms:、smsto:、mms:和彩信：。这允许您的应用程序接收来自其他想要传递消息的应用程序的意图。
在服务中，包括 ACTION_RESPONSE_VIA_MESSAGE ("android.intent.action.RESPOND_VIA_MESSAGE") 的意图过滤器，其中包含模式、sms:、smsto:、mms: 和 mmsto:。此服务还必须需要 SEND_RESPOND_VIA_MESSAGE 权限。
没有这四个，您的应用将不会列在默认的 SMS 选择对话框中。
这是我的 AndroidManifest.xml

实现MmsReceiver、HeadlessSmsSendService、ComposeSmsActivity、SmsBroadcastRceiver
这是关于 MmsReceiver.cs.
的代码
public class MmsReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
Toast.MakeText(context, "Received intent!", ToastLength.Short).Show();
}
}
这是关于 HeadlessSmsSendService.cs.
的代码
public class HeadlessSmsSendService : Service
{
public override IBinder OnBind(Intent intent)
{
return null;
}
}
这是关于 ComposeSmsActivity.cs.
的代码
public class ComposeSmsActivity : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your application here
}
}
这是关于 SmsBroadcastRceiver.cs.
的代码
[BroadcastReceiver(Enabled = true, Exported = true,Permission = "android.permission.BROADCAST_SMS")]
[IntentFilter(new[] { "android.provider.Telephony.SMS_RECEIVED", "android.provider.Telephony.SMS_DELIVER" })]
public class SmsBroadcastRceiver : BroadcastReceiver
{
public SmsBroadcastRceiver()
{
}
public override void OnReceive(Context context, Intent intent)
{
var msgs = Telephony.Sms.Intents.GetMessagesFromIntent(intent);
List<string> msgList = new List<string>();
string address = "";
string body = "";
foreach (var msg in msgs)
{
msgList.Add(msg.DisplayMessageBody);
address = msg.DisplayOriginatingAddress;
body = msg.DisplayMessageBody;
}
markMessageRead(Android.App.Application.Context, address, body);
MessagingCenter.Send<List<string>>(msgList, "MyMessage");
}
public void markMessageRead(Context context, String number, String body)
{
Android.Net.Uri uri = Android.Net.Uri.Parse("content://sms/inbox");
ICursor cursor = context.ContentResolver.Query(uri, null, null, null, null);
try
{
while (cursor.MoveToNext())
{
if ((cursor.GetString(cursor.GetColumnIndex("address")).Equals(number)) && (cursor.GetInt(cursor.GetColumnIndex("read")) == 0))
{
if (cursor.GetString(cursor.GetColumnIndex("body")).StartsWith(body))
{
String SmsMessageId = cursor.GetString(cursor.GetColumnIndex("_id"));
ContentValues values = new ContentValues();
values.Put("read", true);
context.ContentResolver.Update(Android.Net.Uri.Parse("content://sms/inbox"), values, "_id=" + SmsMessageId, null);
return;
}
}
}
}
catch (Exception e)
{
Log.Error("Mark Read", "Error in Read: " + e.ToString());
}
}
}
我在 MainActivity.cs 中添加以下代码以将我的应用程序设置为默认短信应用程序。
//Add this to make your app default
Intent intent = new Intent();
intent.SetAction(Telephony.Sms.Intents.ActionChangeDefault);
intent.PutExtra(Telephony.Sms.Intents.ExtraPackageName, this.PackageName);
StartActivity(intent);
这是我的新演示。
