title: Launch Telegram app from Android application with message and recipient
body: <p>I need to open Telegram from my own Android App prepopulating both the message and recipient (and not having to choose betwenn Chrome or Telegram),
  I achieved the first one with this code:</p>
  
  <pre><code>        final String appName = "org.telegram.messenger";
          Intent tIntent = new Intent(Intent.ACTION_SEND);
          tIntent.setType("text/plain");
          tIntent.setPackage(appName);
          tIntent.putExtra(Intent.EXTRA_TEXT, msg);
          mUIActivity.startActivity(tIntent);
  </code></pre>
  
  <p>And the second one with this code:</p>
  
  <pre><code>        Intent tIntent = new Intent(Intent.ACTION_VIEW);
          tIntent.setData(Uri.parse("http://telegram.me/USERID"));
          startActivity(tIntent);
  </code></pre>
  
  <p>(I removed all checks like isTelegramInstalled for simplicity)</p>
  
  <p>I tried to mix the two methods 
  adding some intent extra such as msg we get to this code that will open Telegram, in one click, with pre-populated message and recipient:</p>
  
  <pre><code>        Intent telegramIntent = new Intent(Intent.ACTION_SEND);
          tIntent.setDataAndType(Uri.parse("http://telegram.me/username"), "text/plain");
          final String appName = "org.telegram.messenger";
          tIntent.setPackage(appName);
          tIntent.putExtra(Intent.EXTRA_TEXT, "hello");
          startActivity(tIntent);
  </code></pre>
  
  <p>...aaand it didn't work!</p>
  
  <p><code>android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.SEND dat=http://telegram.me/... flg=0x1 pkg=org.telegram.messenger clip={null T:hello} (has extras) }
  </code></p>
  
  <p>Any idea how to achieve this?</p>
