USSDダイアログを防ぎ、USSD応答を読み取りますか？

Question

私はussdについて多くの調査を行いましたが、USSD responeを読み取ることができません。このアプリケーションのようなussdダイアログを防ぐにはどうすればよいですか。

https://play.google.com/store/apps/details?id=com.iba.ussdchecker&hl=en

私はこれをインストールします https://github.com/alaasalman/ussdinterceptor 電話を再起動します（S2 Android 4.0.3）、ussdコードを送信しますが、何も起こりません、誰かが言いますログを読まなければならないのですが、どうすればそれを行うことができますか。

ログからUSSDを読み取るためにこれらのコードを試します

        this.view.setText("");
    }

    protected void call(String phoneNumber) {
        try {
            startActivityForResult(
                    new Intent("Android.intent.action.CALL", Uri.parse("tel:"
                            + phoneNumber)), 1);
        } catch (Exception eExcept) {
            this.view.append("\n\n " + "\n" + eExcept.toString());
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        USSD ussd = new USSD(4000, 4000);
        if (ussd.IsFound())
            this.view.append("\n test" + ussd.getMsg());
        else
            this.view.append("" + R.string.error_ussd_msg);
    }

}

そして出力は次のようなものです：

アクセシビリティサービスを利用して可能です。最初にサービスクラスを作成します。

public class USSDService extends AccessibilityService {

    public static String TAG = USSDService.class.getSimpleName();

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        Log.d(TAG, "onAccessibilityEvent");

        AccessibilityNodeInfo source = event.getSource();
        /* if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && !event.getClassName().equals("Android.app.AlertDialog")) { // Android.app.AlertDialog is the standard but not for all phones  */
        if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && !String.valueOf(event.getClassName()).contains("AlertDialog")) {
            return;
        }
        if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED && (source == null || !source.getClassName().equals("Android.widget.TextView"))) {
            return;
        }
        if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED && TextUtils.isEmpty(source.getText())) {
            return;
        }

        List<CharSequence> eventText;

        if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {
            eventText = event.getText();
        } else {
            eventText = Collections.singletonList(source.getText());
        }

        String text = processUSSDText(eventText);

        if( TextUtils.isEmpty(text) ) return;

        // Close dialog
        performGlobalAction(GLOBAL_ACTION_BACK); // This works on 4.1+ only

        Log.d(TAG, text);
        // Handle USSD response here

    }

    private String processUSSDText(List<CharSequence> eventText) {
        for (CharSequence s : eventText) {
            String text = String.valueOf(s);
            // Return text if text is the expected ussd response
            if( true ) {
                return text;
            }
        }
        return null;
    }

    @Override
    public void onInterrupt() {
    }

    @Override
    protected void onServiceConnected() {
        super.onServiceConnected();
        Log.d(TAG, "onServiceConnected");
        AccessibilityServiceInfo info = new AccessibilityServiceInfo();
        info.flags = AccessibilityServiceInfo.DEFAULT;
        info.packageNames = new String[]{"com.Android.phone"};
        info.eventTypes = AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED | AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED;
        info.feedbackType = AccessibilityServiceInfo.FEEDBACK_GENERIC;
        setServiceInfo(info);
    }
}

Android manifestで宣言します

<service Android:name=".USSDService"
    Android:permission="Android.permission.BIND_ACCESSIBILITY_SERVICE">
        <intent-filter>
            <action Android:name="Android.accessibilityservice.AccessibilityService" />
        </intent-filter>
        <meta-data Android:name="Android.accessibilityservice"
            Android:resource="@xml/ussd_service" />
 </service>

Ussd_serviceというユーザー補助サービスを記述したxmlファイルを作成します

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:accessibilityEventTypes="typeWindowStateChanged|typeWindowContentChanged"
Android:accessibilityFeedbackType="feedbackGeneric"
Android:accessibilityFlags="flagDefault"
Android:canRetrieveWindowContent="true"
Android:description="@string/accessibility_service_description"
Android:notificationTimeout="0"
Android:packageNames="com.Android.phone" />

それでおしまい。アプリをインストールしたら、ユーザー補助の設定（設定->ユーザー補助の設定-> YourAppName）でサービスを有効にする必要があります。

Android 2.3で動作しますが、これが上位バージョンで動作するかどうかは完全にはわかりません。指示に従ってください：

1. 電話機のUSBをコンピュータに接続します（デバッグモード）
2. タイプadb devices（お使いの携帯電話がリストされている必要があります）
3. タイプadb Shell
4. タイプlogcat -v time -b main PhoneUtils:D > output.txt
5. 今あなたの電話で、ussdコード例を送信します：＃123＃少し待ってから、コンソールで押します Ctrl + C
6. 読む output.txtとこの単語を検索displayMMIComplete

Answer 3

IExtendedNetworkService.aidlを使用する

このファイルをパスcom\Android\internal\telephonyに作成します

package com.Android.internal.telephony;

/**
 * Interface used to interact with extended MMI/USSD network service.
 */
interface IExtendedNetworkService {
    /**
     * Set a MMI/USSD command to ExtendedNetworkService for further process.
     * This should be called when a MMI command is placed from panel.
     * @param number the dialed MMI/USSD number.
     */
    void setMmiString(String number);

    /**
     * return the specific string which is used to Prompt MMI/USSD is running
     */
    CharSequence getMmiRunningText();

    /**
     * Get specific message which should be displayed on pop-up dialog.
     * @param text original MMI/USSD message response from framework
     * @return specific user message correspond to text. null stands for no pop-up dialog need to show.
     */
    CharSequence getUserMessage(CharSequence text);

    /**
     * Clear pre-set MMI/USSD command.
     * This should be called when user cancel a pre-dialed MMI command.
     */
    void clearMmiString();
}

Manifastにcom.Android.ussd.IExtendedNetworkServiceフィルターを追加します。
