Error inflating class com.google.android.material.appbar.AppBarLayout with AppCompat/Material theme

I don't really know what exactly I am missing but I am getting the same inflate exception error even with an Appcomat theme.
logcat:

I searched and came across this StackOverflow, tried all the solutions that include:
Invalidate Caches/Restart with no luck. Refactor -> Migrate to AndroidX that says No usages found for the project.
I was puzzled and made a separate project with the same single layout that run without any issues but I am unable to differentiate and find the fault here. Please help!

Don't forget to use Theme.MaterialComponents.Light.NoActionBar (or any Theme.MaterialComponents.*.NoActionBar really) as your parent AppTheme in style.xml
implementation 'com.google.android.material:material:1.0.0'
classpath 'com.android.tools.build:gradle:3.2.0'
change Gradle and material design to latest version

I was using SplashScreenApi which is from androidx.core.splashscreen.SplashScreen library.
I knew that I have to call installSplashScreen() before setContentView() in my MainAcitivty() but what I didn't know was that it should be called even before any viewBinding initialization. It went somehow unnoticed for days for someone inexperienced like me. The app was running smoothly and everything was working well until any material design tag implementation.
Before:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
installSplashScreen()
setContentView(binding.root)
...
}
After:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
installSplashScreen()
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
...
}
That was so stupid of me :(. It took me a while cause the logcat was always pointing the setContentView()

Error inflating class ImageButton Stops app from starting

My app fails to start because of Error inflating class ImageButton, Because of this the phone says "app has stopped" Etc.
I am using firebase test lab to debug the problem
the Errors occur on samsung devices specifically A20, s7 Edge , s7(tested with firebase same problem)

It means upload_files_upload is not found in drawble folder, well this can be a case, where your file may present in drawable-24 but not in drawble folder, in that case this problem still arise. The point is your file must be in all drawble folder.

The reason for your error is that the upload_files_upload is not in your drawable folder :
<ImageButton
android:id="#+id/UploadButton"
android:layout_width="300dp"
android:layout_height="209dp"
android:background="#android:color/transparent"
app:layout_constraintTop_toBottomOf="#+id/flexboxLayout"
app:srcCompat="#drawable/upload_files_upload"// this line
android:contentDescription="#string/todo" />

I have solved The Issue I changed app:srcCompat="#drawable/upload_files_upload"// to android:src="#drawable/upload_files_upload"
So the problem was by app:srcCompat I changed it to Android:src and it works fine now

How to fix 'Error inflating class EditText' in Android XML Layout

I am getting following error for the line #30 i.e. first line of first EditText in the provided code. This XML is basically associated with an Activity. The error is while binding XML inside activity
setContentView(R.layout.activity_login)
The error is as follows:

EditText widget should load normally but the activity is crashing with error above.
Providing additional info:
compileSdkVersion 28
minSdkVersion 21
targetSdkVersion 28
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.31"
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

You should set left drawable programmatically if its vector for pre kitkat.
company_code.setCompoundDrawablesWithIntrinsicBounds(AppCompatResources.getDrawable(this,R.drawable.ic_store_white_24dp), null, null, null);```

Which android version you are using, I think you use Vector Drawable in EditText, But Vector Drawable support after KitKat.

Android Studio Facebook SDK - Error inflating class com.facebook.login.widget.LoginButton

Hi to all i'm trying to add the facebook login avaible in the facebook sdk (i'm using the 4.16.0 ver) but i got this error
android.view.InflateException: Binary XML file line #0: Binary XML
file line #0: Error inflating class

</LinearLayout>
edit: the problem is only when I try to inflate the activity, if I use intent I don't have any problem

This is probably because you haven't initialised the Facebook SDK.
Initiate that in the application class as below.
public class AppController extends Application {
#Override
public void onCreate() {
super.onCreate();
FacebookSdk.sdkInitialize(this);
}
}

If you have the same problem, try this.
in your buil.gradle file add this
compile 'com.android.support:multidex:1.0.0'
and add in default config this
default config{
//other stuff
multiDexEnabled true
//other stuff
}
and in yuor application add this MultiDex.install(this);
Thank's myself for answer!

Error inflating class AppCompatButton due to a missing attribute in TypedArray

I have two v4 Fragments in one v7 AppCompatActivity. One fragmet has AppCompatImageButton, the other AppCompatButton. The first one inflates just fine, the other fails with a cryptic error
android.view.InflateException: Binary XML file line #70: Binary XML file line #70: Error inflating class android.support.v7.widget.AppCompatButton
caused by java.lang.UnsupportedOperationException: Failed to resolve attribute at index 5: TypedValue. Both fragments are inflated from the same activity and use the same theme. The only difference is that one button is AppCompatImageButton with just an icon, the other AppCompatButton with an icon and text.
The XML file line #70 is the line where AppCompatButton is defined.
I guess the problem is due to a missing attribute in the Theme, the one at index 5, but how do I find what's at index 5? I tried adding/removing android:tint and android:background, it made no difference.
Here is the relevant piece of the trace:

at co.tinode.tindroid.TopicInfoFragment.onCreateView(TopicInfoFragment.java:43) 
The code at TopicInfoFragment.java:43 is just
return inflater.inflate(R.layout.fragment_topic_info, container, false);
Here is the layout for the Fragment that fails (button on the bottom):
<LinearLayout

android:layout_width="match_parent"
android:layout_height="match_parent"

<LinearLayout

<!-- THIS BUTTON FAILS TO INFLATE -->

</LinearLayout>
Here is the the layout which inflates just fine in the same activity:
<RelativeLayout

<LinearLayout

<!-- This button inflates just fine -->
<android.support.v7.widget.AppCompatImageButton

android:layout_weight="0.1"
android:paddingLeft="4sp"
android:paddingRight="8sp"
android:background="?attr/selectableItemBackgroundBorderless" />
</LinearLayout>
</RelativeLayout>
The theme is quite basic:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="windowActionModeOverlay">true</item>
</style>
Here is the gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion '25.0.0'
defaultConfig {
applicationId "co.tinode.tindroid"
minSdkVersion 15
targetSdkVersion 25
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

packagingOptions {

}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')

compile 'com.android.support:cardview-v7:25.3.1'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'

OK, solved. The problem was with the android:textColor="#color/colorText".
colorText was defined as a reference <color name="colorText">?android:attr/colorPrimary</color>. Once I defined it explicitly, the problem went away.
