It means upload_files_upload is not found in drawble folder, well this can be a case, where your file may present in drawable-24 but not in drawble folder, in that case this problem still arise. The point is your file must be in all drawble folder.

I just have one drawable folder, That is "Drawable" Must I add new drawable folders or what

Suraj Vaishnav Over a year ago

@RubenMeiring No, that is not needed. Will try remove this line: app:srcCompat="@drawable/upload_files_upload" and build your project again. Let me know what happens

Ruben Meiring Over a year ago

the button disapears it is an imagebutton and that removes the image

Suraj Vaishnav Over a year ago

There might be a problem with your image, wil try loading different image in your ImageButton

The reason for your error is that the upload_files_upload is not in your drawable folder :

<ImageButton
            android:id="@+id/UploadButton"
            android:layout_width="300dp"
            android:layout_height="209dp"
            android:background="@android:color/transparent"
            app:layout_constraintTop_toBottomOf="@+id/flexboxLayout" 
            app:srcCompat="@drawable/upload_files_upload"// this line
            android:contentDescription="@string/todo" />

I only have the one drawable folder and the app works on several devices on my phone and several of my colleagues phones

mohammadReza Abiri Over a year ago

Is your upload_files_upload vector drawable?

Ruben Meiring Over a year ago

Yes it is, will that cause an issue??, It is in PNG format if that will make a diffrence

mohammadReza Abiri Over a year ago

did you define defaultConfig { vectorDrawables.useSupportLibrary = true } in your build.gradle?

Ruben Meiring Over a year ago

Yes, I have, the thing is the app works on some phones and some not, its very confusing

I have solved The Issue I changed app:srcCompat="@drawable/upload_files_upload"// to android:src="@drawable/upload_files_upload" So the problem was by app:srcCompat I changed it to Android:src and it works fine now
