missing content description

When I finally got the phone in the program to test the Crystall Ball app, my phone just said “Unfortunately Crystal Ball has stopped.” There are no errors noted and the only warning I’m finding says “Missing contentDescription attribute on image” Here is what I have - 

 <ImageView
        android:id="@+id/imageView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/ball01" />

How do I fix this?

...and now I can't get the code to show up in the post... <ImageView android:id="@+id/imageView1" android:layout_width="match_parent" android:layout_height="match_parent" android:src="@drawable/ball01" />

The forum uses markdown to correctly format code, check out this thread on how to type code in the forum for some examples.

What is line 8 under activity_main supposed to look like? That's the ImageView lines.

So I fixed that 1 warning, so now I have 0 errors and 0 warnings and the app still closes before it starts. Is that the programming or the phone?

Glad you got past the warning. Warnings are usually recommendations that won't cause any problems, like in this case. It's best to fix your code to remove all warnings, but not required.

It sounds like something is wrong with your code. What does your output look like in logcat? Usually it gives some kind of exception that helps track down the error. Have you tried debugging and inserting breakpoints (although I think that's later in the project than where you are)?

I'm not sure what was wrong with the code, but everything is working now. I started again from scratch, which I didn't mind. seeing as how I could use the experience. It still gives me the same warning, (Missing contentDescription attribute on image) and has ImageView in the code above underlined in yellow, but I can get past it now and it's working on my phone. Thanks! Onward and upward!
