android - 如何在各种流行的聊天/社交网络应用程序中打开特定联系人的聊天屏幕？

Question

背景

我发现有一种方法可以在 WhatsApp 上打开特定的联系人对话屏幕，here .

不仅如此，我还发现一个名为“Drupe”的应用程序也有同样的作用，甚至可能更多:

问题

我找不到任何官方API可以用这种方式打开它，所以我不确定它的安全性。

我找到了 SDK，但没有找到 intents 说明。

问题

我想了解更多关于各种社交网络和聊天应用程序可用的内容:

• WhatsApp
• Facebook 信使
• 微博
• 线路
• Telegram
• 环聊

可能的特征可能是:

• 打开联系人的对话，输入他的电话号码
• 准备好在新屏幕中发送的新文本
• 对于 Facebook，也许还可以使用此人的 Facebook-ID(即输入)而不是电话号码打开。

这些社交网络和聊天应用是否都可以使用这些功能？

Answer 1

对于 Facebook 信使，我发现了这个(来自 https://developers.facebook.com/docs/messenger-platform/discovery/m-me-links#format ):

final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://m.me/" + facebookId));

它有效，但我想知道是否有其他方法可以访问它(例如，使用电话号码)。

对于 WhatsApp，我发现了这个(来自 here):

    final String formattedPhoneNumber = getFormattedPhoneNumber(this, phone);
    final String contactId = getContactIdFromPhoneNumber(phone);
    final String contactMimeTypeDataId = getContactMimeTypeDataId(contactId, "vnd.android.cursor.item/vnd.com.whatsapp.profile");
    if (contactMimeTypeDataId != null) {
        intent = new Intent(Intent.ACTION_SENDTO, Uri.parse("smsto:" + formattedPhoneNumber));
        intent.setPackage("com.whatsapp");
    } else
        Toast.makeText(this, "cannot find this contact on whatsapp", Toast.LENGTH_SHORT).show();

public static String getFormattedPhoneNumber(Context context, String input) {
    final PhoneNumberUtil phoneNumberUtil = PhoneNumberUtil.getInstance();
    String normalizedPhone = input.replaceAll("[^0-9+]", "");
    try {
        TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        String countryCode = tm.getSimCountryIso();
        final PhoneNumber phoneNumber = phoneNumberUtil.parse(normalizedPhone, countryCode.toUpperCase());
        final String formattedPhoneNumber = phoneNumberUtil.format(phoneNumber, PhoneNumberFormat.E164).replaceAll("[^0-9]", "");
        return formattedPhoneNumber;
    } catch (NumberParseException e) {
        e.printStackTrace();
    }
    return null;
}

private String getContactIdFromPhoneNumber(String phone) {
    if (TextUtils.isEmpty(phone))
        return null;
    final Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phone));
    final ContentResolver contentResolver = getContentResolver();
    final Cursor phoneQueryCursor = contentResolver.query(uri, new String[]{PhoneLookup._ID}, null, null, null);
    if (phoneQueryCursor != null) {
        if (phoneQueryCursor.moveToFirst()) {
            String result = phoneQueryCursor.getString(phoneQueryCursor.getColumnIndex(PhoneLookup._ID));
            phoneQueryCursor.close();
            return result;
        }
        phoneQueryCursor.close();
    }
    return null;
}

public String getContactMimeTypeDataId(@NonNull Context context, String contactId, @NonNull String mimeType) {
    if (TextUtils.isEmpty(mimeType))
        return null;
    ContentResolver cr = context.getContentResolver();
    Cursor cursor = cr.query(ContactsContract.Data.CONTENT_URI, new String[]{Data._ID}, Data.MIMETYPE + "= ? AND "
            + ContactsContract.Data.CONTACT_ID + "= ?", new String[]{mimeType, contactId}, null);
    if (cursor == null)
        return null;
    if (!cursor.moveToFirst()) {
        cursor.close();
        return null;
    }
    String result = cursor.getString(cursor.getColumnIndex(Data._ID));
    cursor.close();
    return result;
}

它有效，但它不添加消息。它还可能会说联系人没有 WhatsApp。

也可以只使用电话号码，正如我写的 here .

对于 Viber，我发现了这个(来自 here):

        final String contactId = getContactIdFromPhoneNumber(phone);
        final String contactMimeTypeDataId = getContactMimeTypeDataId(contactId, "vnd.android.cursor.item/vnd.com.viber.voip.viber_number_message");
        if (contactMimeTypeDataId != null) {
            intent = new Intent(Intent.ACTION_VIEW, Uri.parse("content://com.android.contacts/data/" + contactMimeTypeDataId));
            intent.addFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET | Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP);
            intent.setPackage("com.viber.voip");
        } else {
            intent = new Intent("android.intent.action.VIEW", Uri.parse("tel:" + Uri.encode(formattedPhoneNumber)));
            intent.setClassName("com.viber.voip", "com.viber.voip.WelcomeActivity");
        }

private String getContactIdFromPhoneNumber(String phone) {
    final Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phone));
    final ContentResolver contentResolver = getContentResolver();
    final Cursor phoneQueryCursor = contentResolver.query(uri, new String[]{PhoneLookup._ID}, null, null, null);
    if (phoneQueryCursor != null) {
        if (phoneQueryCursor.moveToFirst()) {
            String result = phoneQueryCursor.getString(phoneQueryCursor.getColumnIndex(PhoneLookup._ID));
            phoneQueryCursor.close();
            return result;
        }
        phoneQueryCursor.close();
    }
    return null;
}

对于 Hangouts，它似乎与 Viber 类似，但具有以下 mimetype:“vnd.android.cursor.item/vnd.googleplus.profile.comm”。然而，它不起作用，因为它可能需要额外的步骤(设置 G+ 以保持联系人更新并在 G+ 圈子中拥有联系人)。但是，我以某种方式成功地打开了一个人的视频聊天:

        intent =new Intent(Intent.ACTION_VIEW,Uri.parse("content://com.android.contacts/data/"+contactMimeTypeDataId));
        intent.addFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT |Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET |Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP);

对于 Telegram，有人 ( here ) 建议使用下一个代码，但它不起作用:

        intent = new Intent(android.content.Intent.ACTION_SENDUri.parse("http://telegram.me/"+profile)));
        intent.setPackage("org.telegram.messenger");

也可以只使用电话号码，正如我写的here .

对于 Line，我找到了这些(基于 here 和 here )，但都没有用:

    Intent intent = new Intent("jp.naver.line.android.intent.action.LINESHORTCUT");
    intent.putExtra("shortcutType", "chatmid");
    intent.putExtra("shortcutTargetId", target);
    intent.putExtra("shortcutTargetName", "");
    intent.putExtra("shortcutFromOS", false);
    startActivity(intent);

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(Uri.parse("line://msg/text/" + getMongon()));

Skype:这个有效(从各种链接中找到，例如 here):

        final String skypeUserName = getSkypeUserName(phone);
        intent = new Intent(Intent.ACTION_VIEW, Uri.parse("skype:" + skypeUserName + "?chat"));

    public String getSkypeUserName(String phoneNumber) {
        if (TextUtils.isEmpty(phoneNumber))
            return null;
        ContentResolver cr = getContentResolver();
        final Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
        Cursor cursor = cr.query(uri, new String[]{PhoneLookup.LOOKUP_KEY}, null, null, null);
        if (cursor == null)
            return null;
        final Set<String> contactKeys = new HashSet<>();
        // get contact keys
        {
            final int contactKeyIdx = cursor.getColumnIndex(PhoneLookup.LOOKUP_KEY);
            for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()) {
                String contactKey = cursor.getString(contactKeyIdx);
                contactKeys.add(contactKey);
            }
            cursor.close();
        }
        if (contactKeys.isEmpty())
            return null;
        //get raw ids
        final Set<String> contactRawIdsSet = new HashSet<>();
        {
            final StringBuilder sb = new StringBuilder();
            for (int i = 0; i < contactKeys.size(); ++i)
                sb.append(sb.length() == 0 ? "?" : ",?");
            String inParameters = sb.toString();
            final String[] selectionArgs = contactKeys.toArray(new String[contactKeys.size()]);
            cursor = cr.query(ContactsContract.Data.CONTENT_URI, new String[]{ContactsContract.Data.RAW_CONTACT_ID}, ContactsContract.Data.LOOKUP_KEY + " IN (" + inParameters + ")", selectionArgs, null);
            if (cursor == null)
                return null;
            final int rawContactColIdx = cursor.getColumnIndex(ContactsContract.Data.RAW_CONTACT_ID);
            for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()) {
                String rawContactId = cursor.getString(rawContactColIdx);
                contactRawIdsSet.add(rawContactId);
            }
            cursor.close();
        }
        if (contactRawIdsSet.isEmpty())
            return null;
        //find the skype name
        //TODO think of a better way to query, as it looks weird to search within a set of ids...
        final StringBuilder sb = new StringBuilder();
        for (int i = 0; i < contactRawIdsSet.size(); ++i)
            sb.append(sb.length() == 0 ? "?" : ",?");
        String inParameters = sb.toString();
        final String[] selectionArgs = new String[2 + contactRawIdsSet.size()];
        selectionArgs[0] = "com.skype.contacts.sync";
        selectionArgs[1] = "vnd.android.cursor.item/name";
        int i = 2;
        for (String rawId : contactRawIdsSet)
            selectionArgs[i++] = rawId;
        cursor = cr.query(ContactsContract.Data.CONTENT_URI, new String[]{RawContacts.SOURCE_ID}, ContactsContract.RawContacts.ACCOUNT_TYPE + " = ? AND " + Data.MIMETYPE + " = ? AND " +
                ContactsContract.Data.CONTACT_ID + " IN (" + inParameters + ")", selectionArgs, null);
        if (cursor == null)
            return null;
        if (!cursor.moveToFirst()) {
            cursor.close();
            return null;
        }
        String result = cursor.getString(cursor.getColumnIndex(RawContacts.SOURCE_ID));
        cursor.close();
        return result;
    }
