Have a user upload an image to the Android Resources/drawable folder

Question

I need the user to be able to upload an image, and then have the image be able to be accessed later for drawing it. I only know how to show an image in the Android Resources/drawable folder. I don't think it is possible for a user to upload an image there, so is there another place they can upload it, and then have the image to be used? I don't know how to have the user to be able to upload it either.

I only know how to show an image with the xaml code <Image Source="image.png"/> , where image.png is in the Android Resources/drawable folder

Answer 1

Since Resources contained in out raw directory of our project will be packaged inside our APK and will not be writeable at runtime.

So I highly recommend that you use Internal or External Data Storage to store your images and text file.

For more details, you can check: https://docs.microsoft.com/en-us/xamarin/android/platform/files/

And at the bottom of this page: External storage , there is a example which function is to save text file in External storage, it should be helpful for you.

The sample link is here: https://github.com/xamarin/monodroid-samples/tree/master/LocalFiles

If you want to choose Photos and Video, you can use MediaPlugin of jamesmontemagno. Of course, you can achieve this function yourself.
