Execution failed for task ':app:processDebugResources' after cleaning project

Keyword is Resources from

Execution failed for task ':app:processDebugResources'

Therefore, the problem likely exists somewhere in an XML file.

For instance, your manifest's application tag. I don't think that name attribute is valid. Plus, you already have android:name for a different class. Therefore remove the name one. Or change to android:name and keep only one. If you need both classes, then have AppController extend the BootstrapApplication class.

<application
    name="com.example.bliss_000.todolistapp.AppController"

Also, the entire package name isn't necessary.

For example, the MainActivity can simply be

<activity
     android:name=".MainActivity"

For me it was to update the compileSdkVersion and targetSdkVersion in build.gradle from 27 to 28.
