body: <p>If I modify <code>Libraries/Image/resolveAssetSource.js</code> something like below</p>
  
  <pre><code>function assetToImageSource(asset): ResolvedAssetSource {
    var devServerURL = getDevServerURL();
  
    if(devServerURL){
      console.log("devServerURL:"+getPathOnDevserver(devServerURL, asset));
    }else{
      console.log("PathInArchive:"+getPathInArchive(asset));
    }
  
    return {
      __packager_asset: true,
      width: asset.width,
      height: asset.height,
      uri: devServerURL ? getPathOnDevserver(devServerURL, asset) :   getPathInArchive(asset),
      scale: pickScale(asset.scales, PixelRatio.get()),
    };
  }
  </code></pre>
