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:

I have tried couple of things explained in other answers but none of them actually helped me. I am not using any drawable resource for that EditText.

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.

How to solve Error inflating class android.support.design.widget.FloatingActionButton

I have a problem in using Float ActionButton on some devices, (with android version 6.0.1 ,6.0, 5.1.1)
I have tried many ways but still it’s not working
Ways I have tried:
1) I’m using app:rippleColor="#color/white" (instead of app:rippleColor="#android:color/white")
2) Im using app:backgroundTint="#color/fab1" (instead of android:backgroundTint="#color/fab2")
3) I’m using app:srcCompat="#drawable/you_graphics" (instead of android:src="#drawable/your_graphics")
4) My appcompat and design support library versions are the same :
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
Here is my android tag :
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.mvam"
minSdkVersion 14
targetSdkVersion 25
versionCode 5
versionName "1.7.8"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
Here is my Error:

Snackbar Error in activity => android.view.InflateException: <merge /> can be used only with a valid ViewGroup root and attachToRoot=true

After updating the android studio to version 3.1.2 & gradle to version 4.4, I've faced weird problem to show snackbar in an activtiy.

as you can see, the error is about inflating layout but can't understand the reason:
Caused by: android.view.InflateException: can be used only with a valid ViewGroup root and attachToRoot=true
It must be mentioned that I've used every solution that are suggested :
my support design version is : implementation com.android.support:design:27.1.1'
the activtiy is extend from AppCompatActivity
The AppTheme is Theme.AppCompat.Light.NoActionBar
I've used getWindow().getDecorView().findViewById(R.id.layout_coordinator), but nothing is solved
be glad someone could help me.

Finally, I've found the solution:
There is a MERGE tag in the snackbar layout that cause exception while inflating layout. By commenting the related row, the problem is solved.

I found the issue after spending some hours. The issue is I have missed to add textColorHighlight in my style for TextInputLayout. So, I changed my theme from
<style name="TextLabel" parent="TextAppearance.AppCompat">
<item name="android:textColorHint">#color/white</item>
<item name="colorAccent">#color/white</item>
<item name="colorControlNormal">#color/white</item>
<item name="colorControlActivated">#color/white</item>
</style>
to
<style name="TextLabel" parent="#android:style/TextAppearance.Widget.TextView">
<item name="android:textColorHint">#color/white</item>
<item name="colorAccent">#color/white</item>
<item name="colorControlNormal">#color/white</item>
<item name="colorControlActivated">#color/white</item>
<item name="android:textColorHighlight">#color/grey_5f6971</item>
<item name="android:textColorLink">#color/white</item>
</style>
Thanks guys who are helping me in comment and answer section.

It just basically means that it was not able to find primary_text_material_light.xml in your resources res/color.xml
Please paste your xml code to get detailed answer.

library android support 7 should add rightly.you should remove and add libray and then clean your project.

#line number 20 android:id="#+id/backButton"..... .
In your java file do this ImageView img = (ImageView)findViewById(R.id.backButton);
you might be typecasting R.id.backButton with some other view type
