我正在尝试编写代码以从Android应用程序发送短信,但当我尝试发送短信时,它会将错误发送给我:

我检查了但是我在清单中有权限,如下所示:

<?xml version="1.0" encoding="utf-8"?>

<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-feature android:name="android.hardware.telephony"
    android:required="true"/>

<application
    android:exported="true"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity> …

嗨，我想在我的 Android 设备中获取IMEI 号码。而我能够做到。但我收到过时警告说 ' TelephonyManager.DeviceId' is obsolete:'deprecated'。我正在使用此代码在我的 Android 设备中获取 IMEI 号码

Android.Telephony.TelephonyManager mTelephonyMgr;
        mTelephonyMgr = (Android.Telephony.TelephonyManager)Forms.Context.GetSystemService(Android.Content.Context.TelephonyService);

        return mTelephonyMgr.DeviceId;

现在我可以通过使用禁用过时的警告

     mTelephonyMgr = (Android.Telephony.TelephonyManager)Forms.Context.GetSystemService(Android.Content.Context.TelephonyService);
#pragma warning disable CS0618 // Type or member is obsolete
            return mTelephonyMgr.DeviceId;
#pragma warning restore CS0618 // Type or member is obsolete

但是为什么我会收到这个过时的警告？是否有不同的方法来获取 IMEI 号码，我不会收到这个过时的警告？
