Unable to resolve class com.android.build.outputfile

To resolve the “unable to resolve class com.android.build.outputfile” issue, you need to include the necessary dependencies in your project’s build.gradle file. This error is commonly encountered when building Android applications using Android Studio.

Here’s an example of how you can include the needed dependencies in your build.gradle file:

    
      plugins {
          id 'com.android.application'
      }

      android {
          compileSdk 30
          defaultConfig {
              applicationId "com.example.yourapplication"
              minSdk 21
              targetSdk 30
              versionCode 1
              versionName "1.0"

              testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
          }

          buildTypes {
              release {
                  // Configure release build settings here
              }
          }
      }

      dependencies {
          implementation 'androidx.appcompat:appcompat:1.3.0'
          implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
          implementation 'com.android.support:multidex:1.0.3' // This line is important to include multidex library if needed
      }
    
  

Make sure to replace “com.example.yourapplication” with the appropriate applicationId for your project. Additionally, you can add any other necessary dependencies specific to your project.

After adding the dependencies, sync your project to ensure the changes take effect. You can do this by clicking on the “Sync Now” button that appears in the top bar of Android Studio or by selecting “Sync Project with Gradle Files” from the “File” menu.

Once the sync is complete, rebuild your project by selecting “Build” from the top menu and then “Rebuild Project”. This should resolve the “unable to resolve class com.android.build.outputfile” issue.
