Examples of how to port a Web or HTML5 game to a native Android, iOS and Mac OS X App.

The App has a WebView that shows you the content of a embedded HTML file. Also, you can read files from the device and write files to it. For last, in the Android version the Web file is in app/src/main/assets/SpiderGame.htm and in the iOS/Mac OS X version is in www/SpiderGame.htm.

// WebToApp.min.js code added to your embedded HTML file
...

new WebToApp(myArrayBuffer, "myImageFile.jpg");

// WebToApp.min.js code added to your embedded HTML file
...

new WebToApp("example123", "myTextFile.txt");

<input type="file" onchange="readingAFile(event.target.files);" />

<script>
    function readingAFile(files)
        {
        var filereader = new FileReader();
        filereader.file_name = files[0].name;
        filereader.onload = function()
            {
            var myArrayBuffer = this.result;
            var myFilename = files[0].name;
            };
        filereader.readAsArrayBuffer(files[0]);
        }
</script>

• Copy the file WebToApp.htm to some of the available ports to test the described features. You can modify the code of the porting that you want to use to load WebToApp.htm instead of SpiderGame.htm (or just rename WebToApp.htm).

Every downloaded Blob file is automatically written in the Downloads folder. If the file already exists, a new file will be created with a suffix, for example: MyFileName(1).txt.

If your App is not going to save an image, delete the NSPhotoLibraryUsageDescription and NSPhotoLibraryAddUsageDescription keys from the Info.plist file.
