Could please locate your app module .iml file and confirm that the selected build variant is persisted there before you re-open your project?

It looks like (see SELECTED_BUILD_VARIANT):

    <facet type="android" name="Android">
      <configuration>
        <option name="SELECTED_BUILD_VARIANT" value="debug" />
        <option name="ASSEMBLE_TASK_NAME" value="assembleDebug" />
        <option name="COMPILE_JAVA_TASK_NAME" value="compileDebugSources" />
        <afterSyncTasks>
          <task>generateDebugSources</task>
        </afterSyncTasks>
        <option name="ALLOW_USER_CONFIGURATION" value="false" />
        <option name="MANIFEST_FILE_RELATIVE_PATH" value="/src/main/AndroidManifest.xml" />
        <option name="RES_FOLDER_RELATIVE_PATH" value="/src/main/res" />
        <option name="RES_FOLDERS_RELATIVE_PATH" value="file://$MODULE_DIR$/../../../app/src/main/res;file://$MODULE_DIR$/../../../app/src/debug/res;file://$MODULE_DIR$/../../../app/build/generated/res/rs/debug" />
        <option name="TEST_RES_FOLDERS_RELATIVE_PATH" value="file://$MODULE_DIR$/../../../app/src/androidTest/res;file://$MODULE_DIR$/../../../app/src/test/res;file://$MODULE_DIR$/../../../app/src/androidTestDebug/res;file://$MODULE_DIR$/../../../app/src/testDebug/res;file://$MODULE_DIR$/../../../app/build/generated/res/rs/androidTest/debug" />
        <option name="ASSETS_FOLDER_RELATIVE_PATH" value="/src/main/assets" />
      </configuration>
    </facet>
  </component>

From the video is can be seen that AS does not load the project from cached data and instead launches Gradle to obtain build models.

The log file attached does not seem to include log from either before or after re-opening the project.

"pl.ProjectRootManagerComponent - project roots have changed" is fine and expected.

Could you also share your gradle.xml from your .idea/ directory? I wonder how many there are <GradleProjectSettings> elements.

Thank you. The file is fine.

Thank you, I can reproduce the problem. I don't know causes it yet.

Do you use:

1. build.gradle or build.gradle.kts configuration? (or both)
2. Is your buildSrc project in Java or Kotlin?

Thank you

Could you

1. list all the .iml files you project get after syncing? (They may be located both with your sources or under .idea/modules directory on both places).

2. let us know if existing .iml files match the files listed in .idea/modules.xml ?

Thank you

Thank you! Do you happen to have any Kotlin multiplatform or Kotlin/JS modules in your project?

It looks like AS forgets variant selection if it needs to sync the project after opening. WIf it happens whatever the current variant selection is it is reset to the default one.

It can be easily reproduced by following these steps:

1. Create and sync a new Android app
2. Switch its only module to Release build variant
3. Make an irrelevant change to its build file (like adding a comment) and DO NOT sync
4. Close the project
5. Re-open the project

The currently selected variant resets to Debug

The problem is exacerbated by an unrelated bug which causes some projects to be synced each time they are opened.

Also it means that if a project is re-opened after updating the sources from the VCS it might lose its variant selection as well.

I96e3840515e6721188d1a986f7f8c4492097d4dc change fixes the problem for non-native variants.

Re comment #29 - I don't know if we have any. I'll update this bug when I have more details.

Was the fix cherry-picked to 3.6.2?

Since adding

productFlavors {
  myFlavor {
    isDefault.set(true)
  }
}

this has stopped being an issue for me. I use AS 3.6.2.

It's actually an issue for me again, as well. I wouldn't call it a "big issue", because it happens basically all the time so now I'm very well acquainted with it and how to manually fix it.

Re-appeared in 4.1 for me as well. It's sporadic, but I could reproduce it by executing Gradle Sync a couple of times. I see a correct SELECTED_BUILD_VARIANT in my app module .iml. The project has some modules with .gradle.kts files.

Android Studio 4.1.1 which includes the fix has been relased. If you can still reproduce any of these or similar problems in 4.1.1 please open a new bug.

Can confirm, 4.1.1 fixes it for me.

Re comment #44: It does not look like related. I suspect that Android Studio does not see changes to the file system. Could you please open a new issue and share Android Studio log files with us? ( Help | Show Logs.. )
