After migrating to Androidx packages using Android Studio menu option Refactor -> Refactor to Androidx...
I'm getting the following error:
Error inflating class androidx.constraintlayout.widget.ConstraintLayout
Make sure constraint layout is updated to latest version:
implementation 'androidx.constraintlayout:constraintlayout:2.1.3'
And replace your xml tag names
<androidx.constraintlayout.ConstraintLayout>
with
<androidx.constraintlayout.widget.ConstraintLayout>
in every place where it appears using this shortcut:
Windows: CTRL + SHIFT + R
Mac: COMMAND + SHIFT + R
In AndroidStudio 3.3 RC2 I got it resolved by upgrading -
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
to
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
in build.gradle (Module: app)
Note:
This solution is also valid for the release version 3.3 (as per below comment by FireZenk), 3.5.2 (as per below comment by user2350644)
Just replace
<androidx.constraintlayout.ConstraintLayout>
with
<androidx.constraintlayout.widget.ConstraintLayout>
In your project's xml files.
You can use Replace in Path shortcut in mac (⇧⌘F or ⇧⌘R) and windows (Ctrl+Shift+R)
Well in my case I've tried Solution 1 which still was not working. Then I used Solution 2 along with Solution 1.
Solution 1
Updating the current version ConstraintLayout in app level build.gradle file.
From
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
Into
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
Solution 2
Invalidate Caches and Restart Android Studio (If still not working after applying Solution 1).
File → Invalidate Caches / Restart → Invalidate and Restart
I used both of them and It works fine for me.
Note: Solution 1 is important.
I've also face this issue. This issue occur only for constraintlayout dependecy version.
Use 1.1.3 version & hope your issue will be solved:
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
There are two ways to add ConstraintLayout:
implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha3'
then you need to use it like this:
<android.support.constraint.ConstraintLayout
...>
</android.support.constraint.ConstraintLayout>
or using androidx:
implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'
then you need to use
<androidx.constraintlayout.widget.ConstraintLayout
...
>
</androidx.constraintlayout.widget.ConstraintLayout>
Do not mix those two.
Since the Android Studio is updated to 3.3 it will pop this error. I resolved it by upgrading the version for constraint layout in the build.gradle of the app level:
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
TO
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
I use an Android Studio 4.1 and this library for constraint layout:
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
which is updated on 09-Nov-20 and had the same error with inflating a Constraint Layout.
In my case on my Samsung a40 app worked but on my ZTE nubia n1 app crashed instantly.
I figured that a problem was in my layout background image because my png image was too big for an old device with a different screen resolution than the Samsung a40.
I imported a background png image through the file explorer (drawable - right-click- Show in Explorer) and there was actually the problem.
I tried to import images with Android Drawable Importer but I notice this plugin does not work anymore on Android Studio.
SOLUTION RELATED TO ANDROID DRAWABLE IMPORTER:
If you have already installed the Android Drawable Importer on your Android Studio please uninstall it before you start the process of repairing.
To repair the Android Drawable Importer you need ADI-hack-plugin which you can get by following this youtube video from Thomas Samoul.
After you repair the Android Drawable Importer just import your image with it and everything will work fine.
I ran into the same problem none of the solutions above worked. The problem, in fact , was caused by a null pointer exception thrown after I switch to NoActionBar theme while the app was using the ActionBar to setTitle(). The linked stack overflow answer helped me figure it out
Android Studio is updated version 3.3. Please remove the previous version constraintLayout
my case used this
implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'
Thank you
In my case i just had to update the androidx dependencies to the latest version.
EDIT In build.gradle (app) you have to look for the dependencies which contains androidx. Android studio will show you information about the latest versions of these dependencies. Using that information just the change the dependency version.
In AndroidStudio 3.4 I had to downgrade to
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
to get it working again.
Strangely, it worked for when I upgraded androidx.appcompat:...' library to
'androidx.appcompat:appcompat:1.1.0-alpha05' with constraint layout version
'androidx.constraintlayout:constraintlayout:1.1.3' on Android Studio 3.3
For those who have tried all of the above to no vain, downgrading constraintLayout worked for me (after I wrecked my head for 3 days trying everything under the sun).
implementation 'androidx.constraintlayout:constraintlayout:2.1.0'
to
implementation 'androidx.constraintlayout:constraintlayout:2.0.0'

After Update android studio dolphin my old projects xml preview not showing views. Is anyone facing same issue? And have done solution then please share it here.
It's run perfectly fine but preview not working.
What I did tried?
File -> Invalidate Cashes / Restart
Delete build , idea , gradle folder
Restart PC and android studio
but none of that solved my problem.
In my case, I have upgraded the project AGP (Android Gradle Plugin) and then restart the android studio.
Problem Solved.
I'm suffering from same issue/bug. What I did so far?
Attempt 1
File -> Sync Project with gradle files
File -> Invalid catch and Restart.
Delete build folder idea and .gradle folder.
Restart Android studio and restarted my pc as well.
This will do solve in one of the my project which is only 5 screen project. But not solved in my other old projects which are more than 5 year old.
Attempt 2
Tried all step from attempt 1 Also tried what siregar2103 answered
File -> Repair IDE but still have same problem ,But Repair IDE did solve my other project issue/bug.
Attempt 3
All from Attempt 1 and 2 but not solve in my main project so I decided to upgrade my years old project to latest one.
I did upgrade my Gradle from 4.1.3 to 7.3.0
Update all dependency to latest one but I face many error while doing that.
Hilt error and other errors too. Which I'm going to mention below.
For Hilt I did removed all old Hilt related library and and below
kapt "com.google.dagger:dagger-compiler:2.42"
kapt "com.google.dagger:hilt-android-compiler:2.43.2"
implementation "com.google.dagger:dagger:2.42"
implementation "com.google.dagger:hilt-android:2.43.2"
implementation 'androidx.hilt:hilt-work:1.0.0'
kapt "androidx.hilt:hilt-compiler:1.0.0"
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.5.1'
implementation "androidx.navigation:navigation-compose:2.5.1"
In build.gradle file (not .app level)
id 'com.google.dagger.hilt.android' version '2.43.2' apply false
Important note: I did add implementation "androidx.navigation:navigation-compose:2.5.1" dependency because I got
java.lang.IllegalArgumentException: CreationExtras must have a value
by SAVED_STATE_REGISTRY_OWNER_KEY error in runtime.
Other Error which I faced is
Exception is:
com.intellij.openapi.externalSystem.model.ExternalSystemException:
lateinit property _buildFeatureValues has not been initialized
For this I did build gradle using command line and it give me full error which I didn't get when I directly build don't know why? But It's through error related flat dir and aar file so I did removed flat dir code and change aar file implementation code now It's started to build and my app started to install.
Now still some of my file not rendering and that because of I'm using custom attr from style so I'm trying to figuring out why it's happening and I'll update this answer when I find solution for that.
So using above my 60% xml files preview start showing in my old projects. For 40% screen I have to change my default theme to custom theme in preview of xml so it can start rendering.
Repair IDE
Upgrade your code to latest Android Gradle Plugin
This 2 step should solve your problem. And build using command line for more error related details.
Have you try to using Repair IDE? It works for me
I ran into a similar issue when upgrading to Dolphin. I was able to solve this by changing the preview's theme from App.Starting [default] to my app's theme.
Try to update the gradle and sync files. It work for me.
The XML file in your project may contain an error. The reason may be a font issue or a file not linking correctly with your XML layout.
This is for your reference on how to find errors.
Hope you find it useful.
Check what Layout Inspectors you have enabled in Android Studio and try to let only the API 29-30 inspector active.
In my case if in xml custom views have used that my preview screen not show views if I remove or comment custom views in xml layout after that the preview screen show other view perfectly
I know removing custom layouts not solution.
for 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.
In my case, I have upgraded Android Gradle Plugin when update is popUp and then restart the android studio.
My Problem Solved.
I am looking as well for a soluition till now.
From what i see, it has something to do with
AGP or Cardview (Layouts). Many code snipeets relate to this issue.
I am trying to update the AGP version, but it seems, that the enveronmet is more broken than that.
I get as well an empty Field for the gradle version and plugin under settings.
For anyone can not fix this issue, i'm just need to update gradle version and buildtool
buildSrc/src/main/kotlin/Dependencies.kt
object BuildPlugins {
object Versions {
const val buildToolVersion = "7.3.0" //lower version seem not work
and change to 7.4 in gradle/wrapper/gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-7.4-bin.zip
Cannot resolve symbol 'androidx.constraintlayout.widget.ConstraintLayout'
I made an empty activity in Android Studio, ahead of nothing added, in activity_main.xml, there were so many red lines,and the prompt was: Cannot resolve symbol'
while, these code was generated by Android Studio, I tried file->invalidate cashes/restart... and installed all the SDK tools but Google series. The error was still there.
Gradle was successful, and JDK was installed.
Has anyone a solution ?
Make sure constraint layout is updated to latest version:
implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'
This is because your project support android legacy version, check this out in build.gradle, search for this key:
implementation 'com.android.support:appcompat-v7:28.0.0'
If confirmed, you should use the compatible version instead of the androidx version.
That is android.support.constraint.ConstraintLayout.
BTW, are you trying to follow the https://developer.android.com/guide demo? This tutorial sucks.
I am beginner in android and creating a program, whole thing is done but when importing constraintlayout with the importing statement 'import android.support.constraint.ConstraintLayout' code editor highlighed red and shows 'cannot resolve symbol'.
You can try using androidx or use thee version 28.0.0-alpha1 of support library
Refactor and migrate your code to Android X.
Then add this in your build.gradle file app level.
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
Sync changes to the project.
It's a bit hard to guess what the problem is without a code snippet or screenshot of how you're using constraint layout in your XML but I imagine this Gradle issue is caused you have not imported constraint layout to your build.gradle file. Make sure this is in your build.gradle file in the dependencies section:
implementation "androidx.constraintlayout:constraintlayout:1.1.3"
The importing statment is as ...
import android.support.constraint.ConstraintLayout;
I am trying to implement card view by implementing it in my build.gradle.
However while doing this, I am getting an error. It is saying
"Version 28 (intended for Android Pie and below) is the last version of the legacy support library, so we recommend that you migrate to AndroidX libraries when using Android Q and moving forward. The IDE can help with this: Refactor > Migrate to AndroidX... less... (Ctrl+F1)"
I understand how to do it but am not sure if I should since I am not getting any build errors and my gradle is still syncing. Can someone tell me whats going on?
You are using androidx libraries together with a very old version of support library of cardview.
Remove the dependency of support library
//implementation 'com.android.support:cardview-v7:16.0.4'
and add:
implementation 'androidx.cardview:cardview:1.0.0'
More info about androidx here.
You have another option.
Just add the MaterialCard included in the official Material Components library:
implementation 'com.google.android.material:material:1.1.0-alpha10'
and in your xml you can use:
<com.google.android.material.card.MaterialCardView
...>
Just open your project and make the compile and target version to 28 , then sync then go to refractor on toolbar of studio , there you will see migrate to android x just tap on that. It will resolved all your issue.
I have a problem with the preview of my app.
In the log file i have a few errors :
This is a group project but I am the only one encountering this problem. I just downloaded Android Studio so I did not touch anything in the settings.
Any idea?
Add constraint layout dependency in build.gradle
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
Just click the blue text that prompt in your console
or try to add these into your gradle (app level)
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
And you can update them to latest version if Android Studio tells you there's a new version.
