doesn't show picture in android 6 and above

Question

I am trying to learn how to use the camera in an app and this is what I reached , the idea is having a button that opens the camera and that the picture will instantly show

Answer 1

After android 6.0 permission structure has changed. You must check permission on run-time. For example you will select a picture from image gallery, User give permission for gallery access before entering gallery.

You can look this document for this newness.

https://developer.android.com/training/permissions/requesting.html

Sample code for your issue

if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
            == PackageManager.PERMISSION_GRANTED) {
        Log.v(TAG,"Permission is granted");
        return true;
  }

If not, you need to ask the user to grant your app a permission:

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CODE);

Good luck :)
