title: Launch another application in background android
body: <p>In my application, i start another application (not activity) with this code :</p>
  
  <pre><code>protected void launchApp(String packageName) {
      Intent mIntent = getPackageManager().getLaunchIntentForPackage(
              packageName);
      if (mIntent != null) {
          try {
              startActivity(mIntent);
          } catch (ActivityNotFoundException err) {
              Toast t = Toast.makeText(getApplicationContext(),
                      "App not found", Toast.LENGTH_SHORT);
              t.show();
          }
      }
  }
