I'm targeting my app at SDK 28 so I need to use file provider to save captured image. My code function well for select image from gallery and successfully retrieved the intended image to next activity (DetectionActivity). However I couldnt retrieve the image captured from camera to (DetectionActivity). In this case, the image has been saved in my storage device so the file provider works well. Just that it wont display in next activity. I think its because of the image Uri but not so sure. Attached is my SelectImageActivity and DetectionActivity. Please help me on passing the image captured to DetectionActivity. p/s : the code got no error, it just allow user to open camera, snap picture but after that return to the same activity.

Hi every all, I am using Android Studio 4.0.1 and I need to learn some new functions at all (concerning connection to Mysql database). But there is a problem...

I read Amir Ali's article on retrieving drawable images and storing them in a SQLite database, but the code was for only a single image. In the app I'm currently developing, I need to display several images at once, plus then be able to display several new images on the next screen. With roughly 400 images in total to display. I have my Database Table created with data type "BLOB" for the images, but in the table, how do I reference the specific images to go in place? In the article there is the code: img1 = c.getBlob(c.getColumnIndex( "image" )); ... Bitmap b1 = BitmapFactory.decodeByteArray(img1, 0, img1.length); imageView.setImageBitmap(b1); Would I need to do that for every image and specifically put them in the table, or is there another way to reference them? Thank you in advance for your assistance with my problem.
