我自己也一直在寻找这个问题的解决方案，发现这里所有其他的答案都很有帮助。
然而，我对 NativeScript 还是个新手（只学了两天），实际上不知道在哪里以及如何实现所有代码位一起工作。
通过使用这里的答案，我可以继续搜索并找到一个完整的GITHUB示例：NickIliev/nativescript-receiving-shared-content
对于其他大一新生（或女新生）来说，如果你想找一个完整的例子，可以去repo目录下探索/demo/app/目录下的代码，这对我很有帮助，我希望对你也有帮助。

NativeScript应该支持这种场景。下面是我的AndroidManifest在app/App_resources/Android中的默认引导应用程序的外观：

<activity
        android:name="com.tns.NativeScriptActivity"
        android:label="@string/title_activity_kimera"
        android:configChanges="keyboardHidden|orientation|screenSize">

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter> 
            <action android:name="android.intent.action.SEND" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:mimeType="text/plain" />
       </intent-filter>
</activity>

edit：非常简单的实现，可以将Intent发送到我的任何其他应用程序：

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent sendIntent = new Intent(Intent.ACTION_SEND);
                sendIntent.setType("text/plain");
                sendIntent.putExtra("string", "the data Im sending you");

                Intent chooser = Intent.createChooser(sendIntent, "Share with ");

                if (sendIntent.resolveActivity(getPackageManager()) != null) {
                    startActivity(chooser);
                }
            }
        });

除了您必须在AppManifest.xml中添加的Intent过滤器之外，请确保重新构建您的应用（livesync选项可能不会反映AppManifest.xml中的更改）
下面是基本共享的NativeScript实现

var app = require("application");

function onShare() {

    var sharingIntent = new android.content.Intent(android.content.Intent.ACTION_SEND);
    sharingIntent.setType("text/plain");
    var shareBody = "Here is the share content body";

    sharingIntent.addFlags(android.content.Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    sharingIntent.addFlags(android.content.Intent.FLAG_ACTIVITY_NEW_TASK | android.content.Intent.FLAG_ACTIVITY_MULTIPLE_TASK);

    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);

    app.android.context.startActivity(sharingIntent);
}
exports.onShare = onShare;

首先在应用程序/应用程序_资源/安卓清单. xml中更新您的安卓清单. xml
添加如下Intent过滤器

<application        android:name="com.tns.NativeScriptApplication"      android:allowBackup="true"      android:icon="@drawable/icon"       android:label="@string/app_name"
                android:theme="@style/AppTheme">        <activity           android:name="com.tns.NativeScriptActivity"
                        android:label="@string/title_activity_kimera"           android:configChanges="keyboardHidden|orientation|screenSize">

                        <intent-filter>
                <action android:name="android.intent.action.MAIN" />                                
                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>                        
                        <intent-filter>
                                <action android:name="android.intent.action.SEND" />
                                <category android:name="android.intent.category.DEFAULT" />
                                <category android:name="android.intent.category.APP_BROWSER" />
                                <data android:mimeType="text/plain" /> 
                                <data android:mimeType="image/*" />
                        </intent-filter>
                        <intent-filter>
                            <action android:name="android.intent.action.SEND_MULTIPLE" />
                            <category android:name="android.intent.category.DEFAULT" />
                            <category android:name="android.intent.category.APP_BROWSER" />
                            <data android:mimeType="image/*" />
                        </intent-filter>
                                </activity>         <activity android:name="com.tns.ErrorReportActivity"/>  </application>

然后在app.js中添加以下代码行

application.android.on(application.AndroidApplication.activityResumedEvent, function (args) {
        console.log("Event: " + args.eventName + ", Activity: " + args.activity);
        var a = args.activity;
        try {
            var Intent_1 = android.content.Intent;
            var actionSend = Intent_1.ACTION_SEND;
            var actionSendMultiple = Intent_1.ACTION_SEND_MULTIPLE;
            var argIntent = a.getIntent();
            var argIntentAction = argIntent.getAction();
            var argIntentType = argIntent.getType();
            console.log(" ~~~~ Intent is ~~~~ :" + new String(argIntent.getAction()).valueOf());
            String.prototype.startsWith = function (str) {
                return this.substring(0, str.length) === str;
            };
            if (new String(argIntentAction).valueOf() === new String(Intent_1.ACTION_SEND).valueOf()) {
                if (new String(argIntentType).valueOf() === new String("text/plain").valueOf()) {
                    console.dump(cbParseTextAndUrl(argIntent));
                }
                else if (argIntentType.startsWith("image/")) {
                    console.log(cbParseImageUrl(argIntent));
                }
            }
            else if (new String(argIntentAction).valueOf() === new String(Intent_1.ACTION_SEND_MULTIPLE).valueOf()) {
                if (argIntentType.startsWith("image/")) {
                    var Uri = cbParseMultipleImageUrl(argIntent);
                    if (Uri !== null) {
                        var Uris = JSON.parse(Uri);
                        console.log(Uris);
                    }
                }
            }
            function cbParseTextAndUrl(argIntent) {
                var Patterns = android.util.Patterns;
                //let Matcher = java.util.regex.Matcher;
                var ListUrl = [];
                var text = argIntent.getStringExtra(Intent_1.EXTRA_TEXT);
                if (new String().valueOf() !== "null") {
                    var Matcher = Patterns.WEB_URL.matcher(text);
                    while (Matcher.find()) {
                        var url = Matcher.group();
                        ListUrl.push(url);
                    }
                    return { "text": text, "listUrl": ListUrl };
                }
            }
            function cbParseImageUrl(argIntent) {
                var imageUri = argIntent.getParcelableExtra(Intent_1.EXTRA_STREAM);
                if (imageUri != null) {
                    // Update UI to reflect image being shared
                    return imageUri;
                }
            }
            function cbParseMultipleImageUrl(argIntent) {
                var imageUris = argIntent.getParcelableArrayListExtra(Intent_1.EXTRA_STREAM);
                if (imageUris != null) {
                    // Update UI to reflect image being shared
                    return JSON.stringify(imageUris.toString());
                }
            }
        }
        catch (e) {
            console.log(e);
        }
    });

现在，您可以将第三方应用中的内容共享到您的应用。

由于这些答案在2023年都不正确，nativescript 7+的工作方式是
1.添加前面提到的Intent过滤器：

<intent-filter>
       <action android:name="android.intent.action.SEND" />
       <category android:name="android.intent.category.DEFAULT" />
       <data android:mimeType="image/*" />
     </intent-filter>

1.侦听activityNewIntentEvent。这是检索传入Intent并提取额外Intent的唯一方法：

if (isAndroid) {
      Application.android.on(AndroidApplication.activityNewIntentEvent, function (args: AndroidActivityNewIntentEventData) {
        console.log('Event : ' + args.intent);
      });
    }

如果有人正在寻找最新的NS7和NS8兼容版本，这对我和Android都适用。这是在NS8的抽屉模板应用程序上测试的。Javascript部分是主页. js，只需将其内容替换为下面的代码。
NS7和NS8的进口是不同的，这让人们感到困惑。
