Joe Bowser commented on CB-13773:
---------------------------------
I would recommend trying it on a standalone Camera app. I don't know what
Error Code 20 means on your device, but if you're not seeing any permission,
maybe the permission was denied too many times and it decided to just give up
and deny it, which is something Android can do. That said, it should handle
that case a lot better than just showing "20".
> camera.getPicture returns error code 20
> ---------------------------------------
>
> Key: CB-13773
> URL: https://issues.apache.org/jira/browse/CB-13773
> Project: Apache Cordova
> Issue Type: Bug
> Components: cordova-plugin-camera
> Environment: Android platform
> Reporter: Bob Myers
> Priority: Major
>
> A call to `camera.getPicture` returns an error code of "20". This occurs on
> the Android platform. Things work fine on the browser platform.
> This error started suddenly a few days ago, and I cannot identify anything
> specific I did that might have caused it.
> It's very hard for me to present a reproducible case, since this is occurring
> in the context of large app, but I will try to reproduce in a sample app if
> there's no alternative. Meanwhile, I'm posting this issue in the hope that
> someone might know what an error 20 is supposed to mean.
> In case it matters, it strikes me as odd that the device is not asking me for
> access for the camera when I install the app, nor when I try to take the
> first picture.
> This happens on different devices, including Nougat and Oreo. It happens with
> different versions of the camera plugins. What is especially puzzling to me
> is that it happens with a build of my app from a version three months ago,
> even though that application works fine in the field.
> cordova-android version is 6.2.1. Cordova CLI version is 8.0.0.
> Here is some relevant code:
> {code}
> function getPicture(cameraOptions: CameraOptions): Promise<string> {
> const {camera} = navigator;
> if (!camera) throw new Error("missing camera in
> cordova-plugin-camera.util");
> return new Promise((resolve, reject) => camera.getPicture(resolve, reject,
> cameraOptions));
> }
> // Get a picture from the camera, returning a promise for the URL on the
> device.
> private async getPictureCordova(library): Promise<string> {
> const destinationType = isPlatformWindows() ?
> Camera.DestinationType.DATA_URL : Camera.DestinationType.FILE_URI;
> const sourceType = library ? Camera.PictureSourceType.PHOTOLIBRARY :
> Camera.PictureSourceType.CAMERA;
> const cameraOptions: CameraOptions = {
> quality: 50,
> destinationType,
> sourceType,
> allowEdit : false,
> targetWidth: 1280,
> // targetHeight: 960,
> correctOrientation: true,
> saveToPhotoAlbum: false,
> mediaType: Camera.MediaType.PICTURE, // applies only in case of
> library
> };
> this.reset();
> return await getPicture(cameraOptions);
> }
> {code}
