I'm using Android Studio Dolphin | 2021.3.1 & Electric Eel | 2022.1.1
After updating Android studio chipmunk | 2021.2.1 to Android studio Dolphin | 2021.3.1 my all project design preview and layout preview not showing.
If anyone solved this issue please help me.
I have tried all possible ways but didn't find any solution for this.
Below are points that I have tried
Invalidate caches.
Restart IDE.
Repair IDE.
Update Gradle plugin version to 7.3.0 from setting project structure (No working)
Check the Below screenshot so everyone gets an idea of what I have issue faced.
Thanks in advance.
For me, some layouts are working fine but in some layouts, I am getting the below error which used to work in earlier versions of Android Studio.
The same issue I faced in Android (Electric Eel | 2022.1.1). Still, this Issue continues.
I was able to fix this by changing the preview's theme from App.Starting [default] to my app's theme from the Design Tab
After alot of searching and testing, I upgraded my gradle version and its work for me.
Just goto File -> Project Structure or press Ctrl + Alt + Shift + S and then upgrate the gradle version as shown in the image below and then invalidate cache and restart the Android Studio and its working
As shown in the image I upgrade my gradle.
Apparently, there are many people reporting the exact same issue to Google but no concrete solution has been given so far:
Issues with Layout Preview in AS since Dolphin
Layout rendering inside AS stops on most of layout after upgrade to 2021.3.1 RC 1 (worked on Chipmunk)
NPE in AarResourceRepositoryCache.createCachingData (AS Dolphin+)
Dolphin continuously refuses to show Design Layouts
Layout editor preview almost always broken
Layout previews have stopped working
I tried most of the suggestions from the other answers, but the only thing that has worked for me so far was upgrading to Flamingo (2022.2.1 Canary 10) or downgrading to Chipmunk (2021.2.1 Patch 2).
These solutions are obviously far from ideal, but until Google decides to fix this in either Dolphin or Electric Eel, I believe that's what we're stuck with.
In my case, I found two situations.
1. Include
the android studio can't show the XML if it contains the "include" tag.
My project has more than 100+ XML files that have the include, and none of them can show the preview. Otherwise, it was fine.
Setting the app theme doesn't work for this case.
2. Setting app theme
On top of the preview screen, you can select the app theme. (If you can't find it, try enlarging the android window itself. Then the hidden app theme menu will be revealed.)
Then, try setting some theme, such as "AppTheme" or "BaseTheme", etc. Then, for some cases, this will show you the preview.
I tried to update gradle but not work with me.
so after that i changed them from
Theme.MaterialComponents.DayNight.NoActionBar
to
Theme.Material3.DayNight.NoActionBar
work with me
if this solution does not work with you
add this line to root group view in layout
android:theme="#style/Theme.MaterialComponents.Light.DarkActionBar.Bridge"
another solution
down material version to this version
material_version = '1.6.1'
I hope that helps you.
I have same issue as above just solved by doing below things
Setting - SDK tools and check for Android Emulator Update
just Update it and Rebuild project and Done
No need to downgrade API versions.
Note - if not work after it just try to invalidate cach and restart
Option 2
after doing above task try to just update or select app theme from above preview design
To solve temporary this issue. Change theme for preview using "AppTheme". This is work for me. For detail see the attachment file image
Use material:1.8.0-alpha01 dependency. alpha02 has issue showing preview.
New solution:
I just tried the latest canary build of Android Studio Flamingo and it seems that the layout preview is now fixed! At least it works for me again without any problems, with MDC 1.8.0-alpha03 and the latest gradle plugin and gradle version.
Old solution:
It appears to be a bug in Dolphin in connection with API 33, but for me at least the layout preview toolbar is shown. In case the preview toolbar is somehow accessible, the following workaround solves the disappeared preview (at least for me):
Select API 32 in the layout toolbar instead of the preselected API 33.
Then the preview is shown to me as it should and I do not have to downgrade anything and can use the latest gradle version.
Change the AGP Version and Increase Gradle version if you have not in Project structure > Project to latest version the click apply and wait for gradle to complete. After completing, Just Invalidate Cache and restart. It worked for me.
Starting with Android Studio Chipmunk, if you're seeing java.lang.NoSuchFieldError: view_tree_saved_state_registry_owner or java.lang.ClassNotFoundException: androidx.savedstate.R$id in the issues panel, make sure to include a debugImplementation dependency to androidx.lifecycle:lifecycle-viewmodel-savedstate in your module.
If you're seeing java.lang.NoSuchFieldError: view_tree_lifecycle_owner in the issues panel, make sure to include a debugImplementation dependency to androidx.lifecycle:lifecycle-runtime in your module.
If you're seeing java.lang.NoClassDefFoundError: Could not initialize class androidx.customview.poolingcontainer.PoolingContainer or java.lang.NoClassDefFoundError: androidx/customview/poolingcontainer/PoolingContainerListener in the issues panel, make sure to include a debugImplementation dependency to androidx.customview:customview-poolingcontainer in your module.

Workaround Solution : File - Project Structure -
I have also encountered this issue. Switching Android Gradle Plugin to 7.3.0 for all projects and 7.4 for gradle solve this problem.
Try to remove/modify any drawable resource files that you are using as style/background in your layout. It may cause Render problem/Touch size/Touch Target too small. In my case I was using such resource files, after modifying those, the layout is visible to me. Thanks.
I had the same issue and solved it by ignoring some errors in the issue panel
Not this specific issue, this is for example sake
Don't use alpha version. Use this
implementation 'com.google.android.material:material:1.7.0'
In my case solve this issue I do following steps
First I just update Gradle plugin version to 7.3.0 from setting project structure (No working)
after that I also update com.google.gms:google-services version to 4.3.14
now every things work fine.
I was using custom views, styles and fonts from a library and ran into this when upgrading to Dolphin. I fixed the issue by upgrading the libraries compile SDK to 33. Upgraded gradle to 7.3 and upgraded androidx.appcompat:appcompat to 1.4+
Once you do that, invalidate caches and rebuild and it should work.
Google is aware of this issue https://issuetracker.google.com/issues?q=dolphin%20layout%20preview
Downgrading to Chipmunk until a patch is released will also fix the issue if you can't or wont upgrade.
Try to upgrade your gradle version to latest (whatever it may be). Mine Worked
If all these solutions are not working then you can try below option as well.
Disable lottieAnimation in the xml file, and reBuild the app, then it is working fine now.
For you that because of others dependencies cannot update the Android Gradle Plugin:
You'll have to wait a little bit, the devs are already aware. There should eventually be a version to correct this.
For now what you can do to keep working is downgrading the Android Studio Version to Chipmunk | 2021.2.1 (or older)
Maybe it's not going to fix your problem. But it may helps someone who gets into the same trouble as I had. I have an extended layout, the exception says it's not able to initial this class, and pointing to a singleton property variable.
private SingletonProperty property = SingletonProperty.getInstance();
Turns out it's not possible to have a singleton field in a layout class(which it's okay before Android Studio Dolphin). Everything works fine after I move it into several methods. Don't forget to build your project after this.
For me, disabling assertions fixed the issue.
I found the fix here: https://issuetracker.google.com/issues/255525863
To disable assertions, add -da to Custom VM Options:
In case that Android Studio won't start after applying the new options,
the custom VM options file is located at:
macOS:
~/Library/Application Support/Google/AndroidStudio2021.3/studio.vmoptions
I had the same problem if you are using custom views in your layout, checkout this answer https://stackoverflow.com/a/66337620/14599955.
Open Layout Validation tab from right side or search it from toolbar search menu
now see the issue in my case is inside MaterialAutoCompleteTextView
after investigating issue is
android:fontFamily="More Fonts..." font is not point to right one
I also had the problem of the layout page not appearing and it was not solved in any way until I made a copy of it and deleted the entire layout one by one to find out which view had the problem. It is interesting that the copy of the layout was intact and worked exactly.
Frankly guys tried everything as suggested in mentioned answers, but doesn't seems to work for me, might be a recent Android Studio bug.
Sharing something what worked for me (workaround, not a fix)
I accidentally clicked the LayoutValidation tab as mentioned in screenshot, and for now using it to preview my design while updating XML code. Preview gets updated as you make changes.
But yes this might not be helpful if want to make changes using design.
I'm on Android Studio Electric Eel and I managed to fix the issue after a whole day of trying by replacing com.google.android.material:material version 1.8.0 with 1.7.0.
Even though 1.8.0 is now 'stable' it was the one causing the issue.
Downgrade to Android Studio Chipmunk (2021.2.1) Patch 2
https://developer.android.com/studio/archive
It will work after that.
The only way that rendering of XML is going to work is by clearing out all the errors from the issue panels, which in your case from the photo are 4 errors. This worked for me
I just started learning some Android Studio, but when I create a project, the "Hello World" template isn't showing on the preview window, even if I make changes or add elements to the xml layout.
On my phone it shows perfectly, but I can't make it work on the IDE.
This is a known bug. Here are the many options to fix it:
Build > Clean Project
Build > Rebuild project
File > Invalidate Caches/Restart
If all else fails, go to your styles.xml located in res/values. Make sure you're using the parent="Theme.AppCompat.Light.NoActionBar" theme, instead of the default. (If you want a dark theme, do the obvious and change it to Theme.AppCompat.Dark.NoActionBar
Why this happens/Why this fixes it:
For some reason, Android Studio still uses the deprecated ActionBar by default and I don't think the layout editor supports it anymore. Thus it's crashing anonymously.
To use a Toolbar since the ActionBar is deprecated, follow this link:
https://developer.android.com/training/appbar/setting-up
(^ You can probably skip Step 1 in the above link)
After upgrading to Android Studio my styles.xml suddenly has lots of errors.
When trying to change the parent property Android Studio suggests 'TextAppearance.Widget.AppCompat.Toolbar' as a valid value when typing...
Also I had to prefix ?attr/... attributes with ?android:attr like below...
android:background="?android:attr/selectableItemBackground"
Note that my app will compile and run...
Are these bugs? (probably...)
If not; What is the reason for the change?
If so; What prefix is missing for my themes?
Thanks, Ove
It can be solved after Sync project with Gradle, Clean , Rebuild the Project. I think it is a bug of android studio 3.0.
I get that from time to time as well, I usually try the following:
Clean & Rebuild Project
Sync project with Gradle files
File -> Invalidate caches / Restart -> Invalidate and Restart
A combination of these in a random order usually solves it (I know, I know, really scientific method... but hey as long as it works :))
I'm using Android Studio 1.4
It has passed some time since the last time I've created a new project in android studio and today when I did it the android studio does not show anything from the layout preview. Its a blank window and says "Nothing to show".
I think it's related with the new support design library cuz I've never seen this new "default code". I've researched a bit and it's the new android material design guidelines ...
I've already done this:
updated the SDK tools
cleaned the project and rebuild it
invalidated and restarted caches
...and still nothing.
Updated:
I decided to update 1.5.1 it's like this: it's giving me that rendering problem.. I think it's not showing correctly the lower right button, cuz I think it's supposed to be a button with a message icon in it and in my AS just shows the message icon (correct me if I'm wrong).
Choose another theme (other than Holo, for example Theme)
When you create the style incorrectly or from an existing style, this problem usually occurs. So select the "Graphical Layout" select "AppTheme" (The tab with a blue star). And select any of the predefined style. In my case "Light" which should resolve the problem.
Try to 'Invalidate caches & restart'.
Restart your Android Studio by choosing this option. It may take some time.
Then, if still doesn't work try to rebuild your project.
This is a common problem . It can be easily solved by changing res/values/styles.xml to
<!-- Base application theme. -->
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>
Steps :
Go to res/values/
open styles.xml
change from -> style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"
change to -> style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar"
(Just prepend "Base." to "Theme".)
Save the file and check Preview now.
Preview Works Perfeclty now.
Force refresh helped me.
It is at the top of the design tab.
Check again for SDK update because API 23: Android N (preview) is now available, download it properly OR select the API 23: Android 6.0 from the top right of the preview window. check the image
.
.
It (Android Studio) automatically selects the latest one even if it not properly installed. So,
What you need to do is :
install the new one properly
OR
click on the previous one.
Find Styles.xml in Values.(res/Values/Styles.xml)
Change this
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
to this:
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
Then clean and build project. Both of those you can do from build menu.
It worked for me.
Clean build your project by going to Build > Clean build.
It helped me when I had the same problem.
I also go through same problem and do this simple work just go to res->values->style.xml and change
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
to
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
Fast Forward to 2018 and we are still having this issue!
When I had this issue with Android Studio Canary 3.2 today, this is what I did:
I went to
File -> Settings -> Plugins
On the plugins list, I disabled Android Support by unchecking it.
Then, I selected Apply and then, OK.
After this I restarted Android Studio.
On restart, I repeated the process:
File -> Settings -> Plugins
But this time, on the plugins list, I enabled Android Support by checking it.
Then I restarted.
When Android Studio came on, I allowed Gradle do its thing, then I did:
File -> Sync Project with Gradle Files
When this was done, I reopened my xml files or refreshed them anyhow possible
and everything was fine.
Yeah long route, but on a day when I have to deliver at work? It sure works!
TLDR: Just disable and re-enable Android Support and you will be fine
Sometimes layout preview not show only in your current project, try open other project if in other project layout preview work well then the problem in your current project.
in your current project try clean project, rebuild project, if still not working try make changes in your build.gradle app file, such add some implementation then gradle sync , check your layout preview works.
Switch from Blank Activity and use Empty Activity. Change your theme to for example Holo.Light.NoActionBar.
Unlike Blank, Empty is more stripped down thus you may need to add some stuff yourself. Such as add the 2 Override methods onCreateOptionsMenu and onOptionsItemSelected yourself if you need to manipulate controls on the ActionBar and such. Otherwise, no other significant difference.
I faced the exact problem when creating a new project, It seams to be related to the Appcompat Library to solve it:
I replaced : implementation 'com.android.support:appcompat-v7:28.0.0-alpha3' by implementation 'com.android.support:appcompat-v7:27.1.1' And everything worked fine.
In conclusion, The problem is related to a bug in the library version.
But if it is necessary to use the Natesh bhat's solution is for you.
In my case, Android Studio created project including support library which version is RC or beta.
So I tried downgrade version of support library, then worked.
If your library version is RC or beta, try downgrade.
Downgrade this
implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
to this
implementation 'com.android.support:appcompat-v7:27.1.1'
and downgrade also compileSdkVersion, targetSdkVersion if you need.
This problem occurs due to theme compatibility issue.
All you have to do is first navigate to res/values/styles.xml in the project view.There look for base application theme which by default should be the fourth line.
It'd look similar to the following:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
Now, you just have to add 'Base. to the parent.
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
If the project contains multiple themes, it should be ensured that the right theme is selected in the 'Theme for preview' option.
In android studio dolphin, it would look something like this:
It doesn't even show the "Hello World" in the preview when i started my first project,only displays 'Rendering problem' and 'Failed to instantiates one or more class'.This helps me out, try this.....
in the left side menu, GoTo
base-> res-> values-> styles.xml
then write "Base." in the line <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
just before the Theme.AppCompat i.e <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
just refresh your layout by clicking this:
there will be a blue logo at the top left of the "layout-design" page
click and choose "Force Refresh Layout"
In your top Android Studio menu, go to View > Tool Windows > Preview, then it should appear somewhere in the frame of Android Studio, you can move it to the desired place with the dented wheel tool in the Preview frame
For me, in Android Studio 3.6.1, while in the layout.xml file, clicking here showed the preview of the layout again.
I Don't think the "tab" Preview exists anymore, it does now appear to me here: View > Tool Windows > Preview.
Change the Android version to use while rendering layouts in the IDE.
Go to your xml layout file -> Design -> change Android API version from Automatically Pick Best to a value in between your minimum and target sdk versions.
use the below code in build.gradle and it will show your layout preview.
configurations.all {
resolutionStrategy {
force 'androidx.core:core-ktx:1.6.0'
}
}
Please (change com.android.support:appcompat-v7:28.0.0-alpha3) or (com.android.support:appcompat-v7:28.0.0-rc02) to (com.android.support:appcompat-v7:28.0.0-alpha1) in build.gradle (Module: App).
Next click File -> Invalidate Caches / Restart
Need internet access.
It works for me Windows 10 and in Ubuntu 18.04.1 LTS
Clean Project
Rebuild Project
Invalidate Caches / Restart
Android Studio Stuck At Initializing
Close the project
Delete .idea folder in project root folder
Open the
project
Here is a simple solution that worked for me:
Go to File -> Settings -> Apperance & Behavior -> System Settings -> Android SDK :
Check Show Package Details which is located on the bottom right.
Under the latest Android SDK version (for ex: Android 8.1 (Oreo)), check Google Play Intel x86 Atom System Image
Now click apply button
This system image helps android studio to show layout preview.
Changing the theme(near the android symbol for changing API version) from AppTheme to anything else like DeviceDefault or Holo fixed the problem easily.
After so many flip-flap I realised that on xml Preview size above,on the left side of Apptheme we have Android Icon with ears click it and change to your target api in case that its not the same as it targeted on built.gradle
For me this problem keeps appearing after I run the APK at first time. Invalidating did not help.
However, I came with a workaround:
Just run the APK, and while it's running you can submit your changes clicking the "Lightning" button (Apply changes) next to to the "Run" button at the top right panel. Works charming for me, when making changes to the layout.
Follow a few steps:-
1) Clean Project
If 1 doesn't work then
2) Invalidate cache and restart
If 2 doesn't work then
3) run command in the project folder rm -r .idea
Android Studio Stuck At Initializing
android studio 4.1.2 suddenly stuck at initializing preview and XML preview is completely crashed. this is what I have done to fix the issue
go to C:/Users/username/AppData/Roaming/Google
Delete the entire AndroidStudio folder
Invalidate cache and restart your IDE
SOLUTION
Go to Preferences -> Plugin -> Installed.
Search "Android APK Support" -> Disable it
Invalidate Caches & Restart
Re-enable "Android APK Support" plugin
Restart
Done (It should resolve the issue. If you still see the issue on some custom views, just rebuilt/run the project)
PROBLEM
The reason of the issue (from my investigation) is related to some incorrect UI parts, for example:
Incorrect XML layout implementation
Incorrect styles implementation
So if the issue still persists, just try to figure out what part of your UI implemented wrong, and fix it.
I just update Android Studio, and when I restarted it, the preview window rendering failed, and I was told that
The following classes could not be found:
- android.support.v7.internal.widget.ActionBarOverlayLayout
If someone can tell me what can I do to fix this rendering problem? Thank you.
You have to do two things:
be sure to have imported right appcompat-v7 library in your project structure -> dependencies
change the theme in the preview window to not an AppCompat theme. Try with Holo.light or Holo.dark for example.
Please see the following link - here is where I found a solution that worked for me.
Rendering problems in Android Studio v 1.1 / 1.2
Changing the Android Version when rendering layouts worked for me - I flipped it back to 21 and my "Hello World" app then rendered the basic activity_main.xml OK - at 22 I got this error. I borrowed the image from this posting to show you where to click in the Design tab of the XML preview. What is wierd is that when I flip back to 22 the problem is still gone :-).
I had to change my values/styles.xml to
<!-- Base application theme. -->
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
Before that change, it was without 'Base'.
(IntelliJ IDEA 2017.2.4)
I have faced this issue when I introduced additional supporting libraries in my project IntelliJ IDEA
So for me "File" -> "Invalidate Caches...", and select "Invalidate and Restart" option to fix this.
To use the class ActionBarOverlayLayout you need to include this in the dependencies section of build.gradle file:
compile 'com.android.support:design:24.1.1'
Sync the project once again and then you will find no problem
I faced this error when I created second activity in my project in the newly updated Android Studio,I solved it simply by copy pasting the whole xml code from first layout to the second and then I just removed the code that's unnecessary.
