javascript - React JS (JSX) div not rendering unless text is added to div -


i trying render image inside div tag using styling want image dynamically resize based upon size of window.

here jsx code

const heroimage = "pathtoimage";  const heroimagestyling = {   backgroundimage: `url(${heroimage})` };  reactdom.render(   <div style={heroimagestyling}></div>,   document.getelementbyid("root") );

running doesn't render on page

if text added div tag so, small portion of image rendered screen (a long strip same height text)

<div style={heroimagestyling}>test text</div>

how correct problem , render image screen?

div without content , width height won't render. can have 2 approaches here:

  1. put &nbsp; inside div (when don't want define width/height)

reactdom.render( <div style={heroimagestyling}>&nbsp;</div>, document.getelementbyid("root") );

  1. define either width or height or both in div styling

const heroimagestyling = { backgroundimage:url(${heroimage}), height: 200px, width: 200px }; reactdom.render( <div style={heroimagestyling}></div>, document.getelementbyid("root") );

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
