I'm trying to upload selected image by MIT App Inventor II. What I did is to download an extension which encodes image to base64 coding, and then call Web1 to address Google App Script. Actually, what I did is just follow an YouTube channel, but somehow it does not work.
function doPost(e) {
var data = Utilities.base64Decode(e.parameters.data);
var blob = Utilities.newBlob(data,e.parameters.mimetype,e.parameters.filename);
var folderid = Utilities.base64Decode(e.parameters.folderid);
DriveApp.getFileById(folderid).createFile(blob);
return ContentService.createTextOutput("Your File Successfuly Uploaded");
}
Combining with Taifun's Extension. These blocks are confirmed to be able to do as below.
Display the ImagePicker selected image on the Image component
Encode the ImagePicker selected image to a Base64 string.
Send the string to URL (Google App Script)

I trying to create a whatsapp status saver in flutter. I trying to save the whatsapp status. I created a folder statuses in /storage/emulated/0/statuses/ and The process of copying goes well. But that Image is not shown in the gallery app.
So I even Tried storing it in DCIM/Camera still it doesn't show up there. But when the copy the same image using file explorer then that image shows up in gallery app. I think something is wrong with the image properties.
The code used to save is here.
saveFile(filePath) async {
String newFilename;
File originalFile = File(filePath);
Directory _directory = await getExternalStorageDirectory();
if (!Directory("/storage/emulated/0/statuses/").existsSync()) {
Directory("/storage/emulated/0/statuses/")
.createSync(recursive: false);
}
String curDate = DateTime.now().toString();
newFilename = "/storage/emulated/0/statuses/VIDEO-$curDate.jpg";
await originalFile.copy(newFilename).then((value) {
print("Saved: " + newFilename);
});
}
When you change a media, you should tell the device to re-scan. This image saver plugin will notify the Android OS about the media that is saved.
If you don't want the plugin, you can use platform channels to write native code yourself.
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + Environment.getExternalStorageDirectory())));
This issue is discussed here and here.
I want to get image base64 from cahcedNetworkImageProvider widget without redownload it to share it in my App.
or if there's a way to share image as a URL and could be saved to the device in flutter
used flutter_cache_manager plugin to get cached data through this function
var file = await DefaultCacheManager().getSingleFile(url);
and works fine for cached images and if URL is new will download it then get back with file object
Just a little background: As you might know, if you have an image in Google drive and you try to open it with Google Docs, Google tries to extract the text within your image (OCR) and show the text alongside the image in a newly created Google Docs file.
I am writing a script and within that script I would like to open an image (with some text) with Google Docs.
When I try to do it through the following code, I just an Error message with no explanation on why it fails.
var file_url = file.getUrl();
try
{
var doc = DocumentApp.openByUrl(file_url);
}catch (e) {
Logger.log("Error Occurred: " + e.toString());
}
Any help would be appreciated.
Edit 1: Here is an actual scenario. I have the following .png image and I can open it with Google Docs.
When I open with Google Docs, I get the following document:
Document generated after opening the .png image with Google Doc.
Having the url of this .png file, I would like to do all this through my script so I can have the OCR generated text.
You want to convert a PNG file to Google Document by OCR using Google Apps Script.
If my understanding is correct, how about this modification? In this modification, Drive API is used.
When you use this script, please enable Drive API at Advanced Google Services and API console. You can see about this at here.
Modified script:
var fileId = "### file ID of PNG file ###";
var file = DriveApp.getFileById(fileId);
Drive.Files.insert(
{title: file.getName(), mimeType: MimeType.GOOGLE_DOCS},
file.getBlob(),
{ocr: true}
);
Note:
When the URL of PNG file is like https://drive.google.com/file/d/#####/view?usp=sharing, ##### is the file ID.
In this modified script, the filename of created Document uses the filename of file retrieved by fileId. If you want to use other filename, please modify title: file.getName().

Is it possible to attach an image to a tweet using the Twitter share link?
I'm using the following url to tweet but I can't find away to attach an image. The tweet has a link to the image but I want it attached to the tweet so someone can view the image while reading the tweet.
https://twitter.com/intent/tweet?hashtags=MyTag&url=http%3A%2F%2Ftest.com%2Fimage.png
Or would have to use the twitter api?
I would recommend using https://tweetinvi.codeplex.com/documentation which you can programmer directly with twitter.
// Publish with media
byte[] file = File.ReadAllBytes(filePath);
var tweet = Tweet.CreateTweetWithMedia("I love tweetinvi", file);
var imageURL = tweet.Entities.Medias.First().MediaURL;
// Publish with geo information
var tweet = Tweet.CreateTweet("Hello guys");
tweet.PublishWithGeo(-54.73, -64.2);
// Retweet
tweet.PublishRetweet();
I do not believe it is possible to upload media through the share link. Probably, a security decision by Twitter.
I suggest you try the twitpic API.
I'm developing an app for Windows Phone 7 and I'm using a Phonegap template for it.
Everything looks perfect, but now I’m stuck trying to open a PDF file in the browser.
I tried the following but that doesn’t work because the url of the PDF exceeds the 2048 character limit (it’s a data url). This code runs after the deviceReady event was fired.
var ref = window.open('http://www.google.com', '_blank', 'location=no');
ref.addEventListener('loadstart', function () { alert(event.url); });
Now, I'm trying to save the PDF file to storage and then I'm trying to have it opened by the browser, but the browser doesn't show anything. I'm editing the InAppBrowser.cs code from cordovalib and I added the following lines before calling browser.Navigate(loc);
private void ShowInAppBrowser(string url)
{
IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication();
FileStream stream = store.OpenFile("test.pdf", FileMode.Create);
BinaryWriter writer = new BinaryWriter(stream);
var myvar = Base64Decode("the big data url");
writer.Write(myvar);
writer.Close();
if (store.FileExists("test.pdf")) // Check if file exists
{
Uri loc = new Uri("test.pdf", UriKind.Relative);
...
}
}
This code is returning the following error:
Log:"Error in error callback: InAppBrowser1921408518 = TypeError: Unable to get value of the property 'url': object is null or undefined"
I don’t wanna use ComponentOne.
Any help would be greatly appreciated!
You cannot open pdf files from the isolated storage in the default reader for PDF files. If the file is online e.g. it has a URI for it, you can use WebBrowserTask to open it since that will download and open the file in Adobe Reader.
On Windows Phone 8 you actually can open your own file in default file reader for that extension, but I am not sure how that will help you since you target PhoneGap and Windows Phone 7.
Toni is correct. You could go and try to build your own viewer (which would be the same thing as using C1, but with more time involved). I worked on a port of iTextSharp and PDFSharp for WP7, but neither of which are PDF Viewers. They are good for creating PDFs and parsing them some (but to render them there is more work involved). This has been a personal quest of mine, but honestly the best I have gotten is to be able to extract some images from the PDF (and none of the text)
try this
var installedLocation = Windows.ApplicationModel.Package.Current.InstalledLocation;
var assets = await installedLocation.GetFolderAsync("Assets");
var pdf = await assets.GetFileAsync("metro.pdf");
Windows.System.Launcher.LaunchFileAsync(pdf);
This worked correctly on my Device.
