• Trying to open a URL on Android using an intent

  I love tinkering with the Bangle2. It's so fun.

  My goal is to write an app that opens a URL in the browser on my Android device. I was hoping the right way to do this is to send an intent with code like this. I'm unsure what the correct intent would look like, and tried a variety of ideas but none seemed to work. However, there is a weird thing in the Android ADB logs that suggest perhaps this isn't the issue anyway.

  const reddit = JSON.stringify({t:"intent",       
                                 category:"android.intent.category.DEFAUL­T", 
                                 target:"activity", 
                                 data: "https://reddit.com", 
                                 action: "android.intent.action.VIEW"});
  
  const reddit2 = JSON.stringify({
    t:"intent", 
    data: "https://reddit.com", 
    action: "ACTION_VIEW"});
  
  const reddit3 = JSON.stringify({t:"intent", data: "https://reddit.com", action: "android.intent.action.VIEW"});
  
  E.showPrompt("Open url?",{
    title:"Open URL",
    buttons : {"One":1,"Two":2,"Three": 3}
  }).then(function(v) {
    if (v===1) {
     E.showMessage("reddit");
     Bluetooth.println(reddit);
    } else if (v===2) {
     E.showMessage("reddit2");
     Bluetooth.println(reddit2);
    } else {
     E.showMessage("reddit3");
      Bluetooth.println(reddit3));
    }
  });
  

  Strangely, when I look at the android adb logs I see this:

  In other words, the code to receive the JSON is getting a "<" character at the front of it, which means it hits this line and does not try to parse it.

  https://github.com/gfwilliams/Gadgetbrid­ge/commit/60c7f79366f3d62df711bd0d87c333­bd8e67f11d#diff-28d26af2b02f3df362db1ead­5920145a8d90650859a256590ddf1e0926d3368b­R425

  (

  LOG.info("UART RX line started with "+(int)line.charAt(0)+" - ignoring");
  

  )

  Is there something I'm doing wrong with Bluetooth.print() or JSON.stringify() that is adding this extra character? Or, a work around?
