Android Studio - XML Editor autocomplete not working with support libraries

I just started using the new android.support.design library. When using any of the widgets inside the XML editor I stop getting the XML autocomplete suggestions!

For example,

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/header_root"
    android:layout_width="match_parent"
    android:layout_height="200dp">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/primary_dark" />

    <android.support.design.widget.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|right"
        android:src="@drawable/ic_action_add"
        android:layout_marginLeft="16dp"
        android:layout_marginRight="16dp"
        android:layout_marginTop="56dp"
        app:fabSize="normal"
        app:layout_anchor="@id/header_root"
        app:layout_anchorGravity="bottom|right|end" />

</android.support.design.widget.CoordinatorLayout>

None of the tags will show the autocomplete popup, like when I start typing "android:i" no popup appears, the only suggestion I get is shown in the following picture.

enter image description here

I have tried cleaning my project, restarting the pc, restarting Android Studio.. nothing is working!

The answer for me was to switch to lower sdk when compiling project, I think this is platform problem. I was using sdk 33.

Change in build.gradle

compileSdk=32

Edit: It seems that it is also fixed in newest Android Studio version

I tried all, Invalidate Cache, Restart, Clean, and rebuild the project. Downgrading from SDK 33 to 30 also I did after searching. Nothing worked.

In the end, I updated my Android Studio from Chipmunk to Dolphin. Everything is sorted now.

So the final conclusion that worked for me is: Update the Android Studio

If you use compileSdkVersion 33, upgrade your Android Studio to Dolphin. It worked for me.

As this just happened to me, working with Android Studio Chipmunk Patch 2. and nothing of the above answers worked so targeting SDK version number 33 causing this error lowering it solved the issue

    defaultConfig {
            targetSdkVersion = 30
            compileSdkVersion = 30 }

I have this issue when doing my project. I tried everything: Delete every folders if I can; Un-install; Reset to default (I actually search SO for this); Invalidate Cache; Create a very new project for test; Etc... All of those have no resolve problem

Now I have a final way to do: use Intellji instead of Android Studio and I am very happy now. This is advice for anyone who suffered by this issue

Tried everything like deleting .idea folder, power saver mode, deleting cache folder under user/.android , invalidate cache and restart, etc nothing worked.

Setting compileSdkVersion 31 (latest till date) worked for me.

I just tried waiting for 10 seconds and the auto-complete suggestions appeared(Using Android Studio 4.2) , it seems that the xml just takes some time to resolve them.
And no my PC is not slow.

My issue was that I tried to autocomplete on an xml layout file inside res/xml. Autocomplete does not work there for layout files. Moving the xml file to res/layout made autocomplete work again.

I have tried a lot of things (restart Android Studio, PC, Invalidate Caches, Power Saver mode,...).

Finally, deleting the .idea folder and all .iml files from the project, restarting Android Studio, and rebuilding Gradle did the trick. Autocomplete in XML support library is working again.

Checking out files from Version Control or copying all the source files in a new project would do the trick as well.

Change to an older version in build.gradle(Module: app) -Make sure is the one under Gradle Script and it is NOT build.gradle(Project: yourproject). After getting XML autocomplete suggestions change to the current version.

If NONE of the above answers worked, ...

Just navigate to your android studio installation directory, i.e,

yourDrive:/.AndroidStudio3.3/system

and DELETE THE CACHE FOLDER ( first close android studio, if its running ).

Then start Android Studio again. Done.

P.S I am using android studio 4.0

One possibility is to check power mode in the android studio. Go to File > Power mode and check it's on or off. If it is on, You also will not get any suggestions. To get suggestions, It must be off.

If it doesn't work for you then you should reset your Android studio which will set the default configuration for you. For that, find out .AndroidStudioBeta or .AndroidStudio folder and delete those and restart the android studio. Generally, you will get this folder into users\[user name]\.AndroidStudio3.3.

Let me know if it helps you then. Happy coding..!

I too faced this issue and this was only happening on an imported module class. Tried everything like deleting .idea folder, power saver mode, invalidate cache and restart, etc.

Finally updating compileSdkVersion and buildToolsVersion of the module to match with the app module fixed the issue.

In my case I was using:

  compileSdkVersion 29
  buildToolsVersion '29.0.3'

Check 5 ways:

Restart Android Studio
File -> Invalidate Caches / Restart... -> Select Invalidate and Restart
File -> turn of power save mode and restart Android Studio
Delete .idea folder. Search for *.iml files and delete all those and use way number 2

The Santanu Sur answer works for me! But in Windows I found these folders in %USERNAME%/.AndroidStudio3.4 or %USERNAME%/.AndroidStudio3.3

I deleted these two folders and it worked well finally.

The best option is to make a zip folder of the project and change its path.(Relocate this project than open it). This will do the needful.

What worked for me was renaming $USERDIR/.AndroidStudio3.3/system folder and restarting AS.

Delete the complete folder ` of the android studio and then restarting it. Solve the problem

driveLocation:/.AndroidStudio3.3

.AndroidStudio3.3 may be different in your case

A few years too late, but I wanted to submit an answer to this that I figured out and worked for me. It was very quick and didnt require a lot of reconfiguration as some of other answers on here had, so I thought I'd add it.

Solution

Comment the gradle dependencies for xml attributes, sync the project, and then un-comment them and sync it again. For me, resyncing these three with and then without the comments was enough to get them to start coming up again.

//implementation 'com.android.support:appcompat-v7:27.1.1'
//implementation 'com.android.support.constraint:constraint-layout:1.1.3'
//implementation 'com.android.support:design:27.1.1'

And don't worry if your build fails after the first step, it should if you already have any of those attributes in your project. Another note, the attributes that I had previously put in (without the autocomplete before the resync) needed to be re-inputted for some reason.

This same problem appeared in version 3.2. . The solution for that is

Close Android Studio
Go to C:\Users\UserName\.android and rename the build-cache folder to build-cache.bak

Go to C:\Users\UserName\.AndroidStudio3.2\system and rename these folders

caches to caches.bak

compiler to compiler.bak

compile-server to compile-server.bak

conversion to conversion.bak

external_build_system to external_build_system.bak

frameworks to frameworks.bak

gradle to gradle.bak

resource_folder_cache to resource_folder_cache.bak

Open the Android Studio and open your project again.

I tried with Invalid caches/restart option but it didn't work for me. For Android Studio 3> versions check following first:

compileSdkVersion
targetSdkVersion
buildToolsVersion

Set these 3 to the latest version and then try to sync the project and clean, ReBuild once. It will work and show the XML editor autocomplete options.
