Android Studio: Unfortunately “my App” has stopped
I’m new to Android development. After writing my code and running the debugger, my application fails to open with “Unfortunately the application has stopped”.
Here is my stack trace.

Does anyone know what my problem is? I need to work it out because this is my last year project.

I’m sure you’re following the “Eat-it” app tutorial on youtube. I had the same challenge, and I was equally skeptical that it had to do with
info.hoang8f.widget.FButton
What I tried was to go into my gradle file (application) and comment out the call to the api, and also change every occurrence of it in the app from info.hoang8f.widget.FButton to button so I could have no buttons, no more errors.
Also check your styles.xml file, if there is an error with the “theme”, if not, try checking the code. If any of your files throw any errors, it should tell you.
If all else fails, check here< a href="https://stackoverflow.com/questions/46947665/error-inflating-class-info-hoang8f-widget-fbutton" rel="noreferrer noopener nofollow">Error inflating class info.hoang8f.widget.FButton
If you are using Android Studio v3, you may need to change your Gradle version, and your Gradle version will also show as 3, so you can downgrade it in the build.gradle (project) file, for example:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
NOTE: Do not place your application dependencies here; they belong
in the individual module build.gradle files
}
}
