Android Studio indexing every 2 seconds

[lwasyl]

In Android Studio 3.1 Beta 1 (and 3.2 Canary 1) indexing is triggered every 2 seconds, which makes e.g. code completion tooltips go away. Excerpt from the log (this continues forever):

2018-02-04 12:39:19,749 [e-1024-b01]   INFO - pl.ProjectRootManagerComponent - project roots have changed
2018-02-04 12:39:19,762 [ thread 11]   INFO - .diagnostic.PerformanceWatcher - Pushing properties took 1ms; general responsiveness: ok; EDT responsiveness: ok
2018-02-04 12:39:19,772 [ thread 11]   INFO - .diagnostic.PerformanceWatcher - Indexable file iteration took 10ms; general responsiveness: ok; EDT responsiveness: ok
2018-02-04 12:39:21,760 [e-1024-b01]   INFO - pl.ProjectRootManagerComponent - project roots have changed
2018-02-04 12:39:21,772 [ thread 12]   INFO - .diagnostic.PerformanceWatcher - Pushing properties took 0ms; general responsiveness: ok; EDT responsiveness: ok
2018-02-04 12:39:21,776 [ thread 12]   INFO - .diagnostic.PerformanceWatcher - Indexable file iteration took 4ms; general responsiveness: ok; EDT responsiveness: ok

This also happens when there's no tab with Flutter/Dart code.

Steps to Reproduce

• Create new Flutter Project (in Android Studio 3.0, because of FlutterNewProjectAction not found #1649);
• open main.dart file
• observe indexing

This is in android studio 3.1 (not in the stable android studio)?

This looks suspicious:

INFO - pl.ProjectRootManagerComponent - project roots have changed

but I'm not sure what would be causing it. This:

This also happens when there's no tab with Flutter/Dart code.

Makes me think that this is an issue with Android Studio itself, and not necessarily the Dart or Flutter plugins. Perhaps re-file this issue here: https://developer.android.com/studio/report-bugs.html ?

[lwasyl]

I don't have much time, so will investigate later, but regular (big) Android project doesn't trigger indexing, and I've been working on 3.1 for a long time now, and never had this problem.

I've tinkered a bit with the project, removing things one by one, and at some point indexing stopped and seemed to work after I restored all the files. But as soon as I restarted Android Studio, indexing is resumed, and removing things from iml file doesn't seem to work.

Things I've tried that seem to help (sometimes) is removing and readding contents of configuration tag in .._android.iml project. This triggers autogeneration error and indexing stops, but I'm not sure whether everything works normally afterwards

Fixed in #1908

[geiszla]

I just updated to Android Studio 3.1 and have the same problem. How do I convert my existing project to get rid of this constant refreshing?

The workaround of @lwasyl worked until I restarted Android Studio, when the issue came back.

[devoncarew]

We're releasing a new version of the plugin shortly which will address this; thanks for your patience!

[stevemessick]

For those who are curious, you need to change your android facet (in the module definition *.iml file) to include this:

<option name="ALLOW_USER_CONFIGURATION" value="false" />

That is required by a change in the Android Studio code that was made in 3.1. You can dig through #1908 for the details.

@stevemessick where exactly do i put this in my .iml file(s)? I've tried in various spots and the indexing/insanity continues

[lemonboston]

@acidjazz I've added that line in the <myproject>_android.iml file at the root (not in <myproject>.iml). It looks like this currently:

<?xml version="1.0" encoding="UTF-8"?>
<module type="JAVA_MODULE" version="4">
  <component name="FacetManager">
    <facet type="android" name="Android">
      <configuration>

        <option name="GEN_FOLDER_RELATIVE_PATH_AIDL" value="/android/gen" />
        <option name="MANIFEST_FILE_RELATIVE_PATH" value="/android/AndroidManifest.xml" />

@acidjazz dude instead of waiting for someone else to fix - find a way. Download an older version of Android Studio, do some searching on StackOverflow, follow the instructions above. The longer you wait for someone else to solve your problems the more miserable you will become. Become your own hero.

[stevemessick]

To fix the refresh issue on projects already open in 3.1 you need to close them then re-open them. Use the Welcome screen item named Open an existing Android Studio project. See #2017 for more info.
