Android - Send Telegram message to a specific number

Question

I'm trying to send a Telegram message to a specific number from within my Android app. Right now my code launches Telegram app, and then the user has to select the destinatary. What I want to do is to send the message to the specified number, without having the user select the contact. My code is as follows:

/**
 * Intent to send a telegram message
 * @param msg
 */
void intentMessageTelegram(String msg)
{
    final String appName = "org.telegram.messenger";
    final boolean isAppInstalled = isAppAvailable(mUIActivity.getApplicationContext(), appName);
    if (isAppInstalled) 
    {
        Intent myIntent = new Intent(Intent.ACTION_SEND);
        myIntent.setType("text/plain");
        myIntent.setPackage(appName);
        myIntent.putExtra(Intent.EXTRA_TEXT, msg);//
        mUIActivity.startActivity(Intent.createChooser(myIntent, "Share with"));
    } 
    else 
    {
        Toast.makeText(mUIActivity, "Telegram not Installed", Toast.LENGTH_SHORT).show();
    }
}

Answer 1

You can't send to special number, But You can do this by USERID

try {

    Intent telegramIntent = new Intent(Intent.ACTION_VIEW);
    telegramIntent.setData(Uri.parse("http://telegram.me/USERID"));
    startActivity(telegramIntent);

} catch (Exception e) {
        // show error message
}

This code will show user an alert for choosing applications that support telegram uri's like Telegram itself and Mobogram!

Tip: don't set package name. some people install telegram alternatives like mobogram.
