I got some strange behaviour of my android studio.
On my "watcher" window i have different result from that there really is.
The Watcher does not want to show static final string from a Preferences class, but from the code it looks fine.
Whats wrong?
I attached a video demostration
If i evatule in watcher
Preferences.KEY_PREF_PAY_BUTTONS
i got null
From the App and from sources i can see that this thing is static final and it unit to non null string.

After updating android studio to version 4.2 I am unable to find elements in an activity by their id name. At first I thought it was only a problem with the recyclerView, but I cannot find simple textViews or buttons even when it matches the id perfectly. What is happening here, it has broken all my android projects with hundreds of unresolved reference errors.
You might be using Synthetics, this is deprecated. I suggest you to migrate to View Binding:

Additionally, the first parameter in both makeText method calls have a wrong type. Call getActivity there in order to get a Context:

The uploader is using android studio version 2.3.3,while I am using android studio 3.3.1 . So I am aware that there are few changes here and there. Right now, I am stuck at one such change from that version of picasso....
I have used the exact code group as him, but to me,it gives error at "load"
enter image description here
This is what it says-
enter image description here
I have added this version of picasso as dependency in my build.gradle..
enter image description here
Can anyone help me out here please? What could be triggering error in 'load',and how do I fix it? Thanks in advance
It's just a typo. Instead of writing
Picasso.with(getBaseContext().load(food.getImage())).into(food_image);
use
Picasso.with(getBaseContext()).load(food.getImage()).into(food_image);
You did a typing mistake over there. A method that is started must be closed. What you typed:
Picasso.with(getBaseContext().load(food.getImage())).into(food_image);
What is should be:
Picasso.with(getBaseContext()).load(food.getImage()).into(food_image);
^
Check that you started the with() method and didn't close it.

error
xml layout
Please help me, when I run the application directly out "unfortunately the application has been stopped". Before the button was changed to ImageButton, its application can run normally.
You need to change your referencing of Button in your activity to ImageButton.
I assume:
Button btn=(Button)findViewById(R.id.button);
Change that to:
ImageButton btn=(ImageButton)findViewById(R.id.button);

I have
I am making an app about a simple test that tells the truth. I want to turn the led of the camera on/off. Can anybody tell me where is the error here?
This is not an error, but a warning "Deprecated Class", this mean Camera class can be removed(not supported) from future versions of Android.
Follow this link for new Camera apis.
According to the Java Documentation:
Deprecated Class >> A program element annotated #Deprecated is one that programmers are discouraged from using, typically because it is dangerous, or because a better alternative exists.
