Day 50
• Fixed several issues with Gradle (see thread)
• Started a Shopping List App that focuses on TDD

(same course)▾

Self-Comment
• The gradle issues are becoming easier to fix thanks to them following the same pattern. Although I've yet to experience this many issues until I started to dive into Testing. I wonder if it's because I'm using AS Arctic Fox Canary 15 instead of an AS stable version. I was having similar issues when I attempted AS 4.2...
• Half way to the 100 day mark! I'm going to have to pick up the pace after the last 10 days of progress 👀🎉Kandroid dance
Goals Tomorrow
• Continue Testing
• Possibly do this problem (random easy on Leetcode)

Issues with finding double META files in a new project. I'm not sure why.. As I've solved this recently, I went ahead and added the following code to my build.gradle.kts (:app) file

packagingOptions {
        exclude("META-INF/*.")
    }

exclude is now deprecated. Changed the code above to:

packagingOptions {
        resources.excludes.add("META-INF/*.")
    }

Fixed replacing

classpath "com.android.tools.build:gradle:4.0.2"

with

classpath 'com.android.tools.build:gradle:7.0.0-alpha15'

I realized I'm using Arctic Fox Canary 15, while the tutorial is probably made with the stable version of Android Studio 😅

Another error that involves excluding packaging options:

* What went wrong:
Execution failed for task ':app:mergeDebugAndroidTestJavaResource'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.MergeJavaResWorkAction
   > 2 files found with path 'win32-x86/attach_hotspot_windows.dll' from inputs:

     Adding a packagingOptions block may help, please refer to
     <https://google.github.io/android-gradle-dsl/current/com.android.build.gradle.internal.dsl.PackagingOptions.html>
     for more information

added

packagingOptions {
        exclude "**/attach_hotspot_windows.dll"
        exclude "META-INF/licenses/**"
        exclude "META-INF/AL2.0"
        exclude "META-INF/LGPL2.1"
    }

Did the trick to solve this
