The system camera app will be started directly, instead. Be aware, however, that on Android this means that the user will no longer have the option of choosing an existing picture. The capture attribute works on Android and iOS, but is ignored on desktop. Īdding the capture attribute without a value let's the browser decide which camera to use, while the "user" and "environment" values tell the browser to prefer the front and rear cameras, respectively. You can also optionally add the capture attribute to the element, which indicates to the browser that you prefer getting an image from the camera. The files property is a FileList object, which I'll talk more about later. addEventListener ( 'change', ( e ) =>ĭoSomethingWithFiles (e. getElementById ( 'file-input' ) įileInput. The data can then be attached to a or manipulated with JavaScript by listening for an onchange event on the input element and then reading the files property of the event target. In Chrome and Safari on iOS and Android this method will give the user a choice of which app to use to capture the image, including the option of taking a photo directly with the camera or choosing an existing image file. On desktop it will prompt the user to upload an image file from the file system. You can also use a simple file input element, including an accept filter that indicates you only want image files. CORS prevents you from accessing the actual pixels unless the server sets the appropriate headers and you mark the image as crossorigin the only practical way around that is to run a proxy server. Though, if you want to manipulate the image in any way, things are a bit more complicated. Create an img element, set the src and you're done. For just displaying the image this works everywhere. Get the user to give you a URL, and then use that. This is the best supported but least satisfying option. The easiest thing to do is simply ask the user for a pre-recorded file. If you want to progressively enhance your experience, you need to start with something that works everywhere. So how can you create an experience that uses a user generated image that works well everywhere? Start simple and progressively # On top of that, not every device even has a camera. However, depending on the browser it might be a full dynamic and inline experience, or it could be delegated to another app on the user's device. Many browsers now have the ability to access video and audio input from the user. Ask permission to use camera responsibly.Stop streaming from the camera when not needed.Ok, I tried removing the whitespace in my filepath to check if the whitespace was really what was causing the problem and it still didn't work File folder = new File(Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_DCIM) + parator + "TBSystem" + parator + patient_id + parator + "lab_result_" + sqlDateToString(result_date) + ".jpg") Īlso, how come it works on my other class with the whitespace and not on this one? :( File folder = new File(Environment.getExternalStoragePublicDirectory(Įnvironment.DIRECTORY_DCIM) + parator + "TB System" + parator + patient_id) įolder = new File(Environment.getExternalStoragePublicDirectory(Įnvironment.DIRECTORY_DCIM) + parator + "TB System" + parator + patient_id + parator + "lab_result_" + result_date + ".jpg") īyte decodedBytes = code(encoded_image, 0) īitmap imageBitmap = codeByteArray(decodedBytes, 0, decodedBytes. I tried checking my manifest file and see if I included the needed permissions and if they are in the right places I don't understand how it worked on my other class and not in this However, in another class, I'm trying to download an encoded image in text form and save it locally using the method i used above but it doesn't work anymore. This works and I am able to save the the image in a custom folder I created on my android phone. I have a class in my project to upload an image and save in my database and if successful, save it locally.
