title: How to open from my app a specific activity from an other app?
body: <p>I'm developing an app that opens other apps with intents and it works perfectly, but now i need to open a specific activity (or part of the app) and i don't know if it's even possible.</p>
  
  <p>In this case i want to open Street View from the Google Cardboard app. I can't figure out or find the way of doing it.</p>
  
  <p>Here is the intent im using (that works but does not full fill the task):</p>
  
  <pre><code>public void actionOpenCardboard(View view) {
      Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.google.samples.apps.cardboarddemo");
      if (launchIntent != null) {
          startActivity(launchIntent);
      }
  }
  </code></pre>
