title: I keep getting error "No Activity found to handle Intent"
body: <p>I'm trying to do as simple thing as opening web page from my app. I think code should look something looke below, but I keep getting error "no activity found" while executing code:</p>
  
  <pre><code>    public class MainActivity extends Activity {
      public static final String MY_STRING =  "com..example.MY_STRING";
      Button button1;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          button1 = (Button) findViewById(R.id.button1);
          button1.setOnClickListener(clickListener);
  
      }    
      public OnClickListener clickListener = new  OnClickListener(){          
          @Override
          public void onClick(View arg0) {
  
              Intent launchBrowser = new Intent(Intent.ACTION_VIEW, Uri.parse("www.example.com"));                
              startActivity(launchBrowser);               
          }           
      };      
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          // Inflate the menu; this adds items to the action bar if it is present.
          getMenuInflater().inflate(R.menu.main, menu);
          return true;
      }
  
  }
