Android Studio - Uri上传到Firebase

Question

I'm trying to use the camera to take a picture and upload it to Firebase storage. My app is connected to Firebase and passes the dependencies checks. The code compiles fine and when I click on my button to open the camera, it opens the camera and lets me take a picture. As soon as I'm done taking the picture and click okay to go back to the activity, it crashes the app. I've tried several variations, and all seems to end the same way. I have a front image, back image, and selfie, but I'm only working on the front image so that I can get it to work, then I'll add the back image and selfie picture. I have the Firebase storage rules wide open so that anyone can write to it (this is a test environment with no real data).

Any thoughts on what would be crashing it?

Answer 1

Okay - the provider issue was the real issue. Once I fixed that, the CharSequence issue was a make.toast issue that I created myself to try and troubleshoot the provider issue. So once I fixed both, no more crashes. It's still not writing the image file to Firebase, but that's for another thread if I can't get it working on my own.
