Android: TextInputLayouts always have an error icon

I have noticed that since a few days, all my TextInputLayouts have the "error exclamation point" always enabled. I haven't changed anything about those TextInputLayouts for a long time, so I really don't understand what is happening.
Here is a screenshot of how it looks:
Do you have have any idea what could be the source of this issue? Did something recently changed with the TextInputLayouts?
Thank you very much in advance
EDIT
Here is the related code:
The .xml file is really simple. It's a list of TextInputLayouts and EditTexts like this:
<com.google.android.material.textfield.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/default_margin"
android:layout_marginTop="#dimen/default_margin"
android:layout_marginRight="#dimen/default_margin">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/txtAddressTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/PROFILE_SCREEN_ADDRESS_INPUT_TITLE"
android:inputType="textPersonName|textCapWords" />
</com.google.android.material.textfield.TextInputLayout>
Also, there absolutely no mention of setError() in my Kotlin code.

You can try this. But It will permanently remove the error Icon. If you want to show it again you have do it programmatically.
app:errorIconDrawable="#null"

Edit:
It looks like it's fixed with com.google.android.material:material:1.2.0-alpha04.
Ho, I found the issue. I actually updated the version of the Material library from version com.google.android.material:material:1.1.0-alpha08 to com.google.android.material:material:1.1.0-alpha09.
Google changed the behaviour of Text Field (see here: https://github.com/material-components/material-components-android/releases/tag/1.1.0-alpha09):
Text Field:
Adding option to set TextInputLayout icons to be not checkable (6a88f2b)
Implementing error icon for text fields (3f73804)

Accessibility Checks - TextInputEditText has contradictory exceptions

All, we're using the Espresso Accessibility Checking and are getting the following errors for the same view. What's the best way to fix this? Removing the content description fixes the second error but the first still remains. Is there a way to satisfy the Accessibility Checker for TextInputEditText?
https://developer.android.com/training/testing/espresso/accessibility-checking
AccessibilityViewCheckException: There were 2 accessibility errors:
TextInputEditText{id=2131362592, res-name=reason}: View is missing speakable text needed for a screen reader
TextInputEditText{id=2131362592, res-name=reason}: Editable TextView should not have a contentDescription.

I noticed that this error will go away if you set the hint in the TextInputEditText and remove the labelFor in TextInputLayout.
According to Google documentation, setting the hint is the way to tell Accessibility about your view for EditTexts.
When labeling editable elements, such as EditText objects, use the android:hint XML attribute for static elements and the setHint() method for dynamic elements to indicate each element's purpose. (Source)
Also, in Google's example of TextInputLayout, it does not specify that you need to have the labelFor field. (Source)
Code Example:
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TextInputEditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/edit_text_hint"/>
</android.support.design.widget.TextInputLayout>
I am aware that this post is in direct contradiction to this post:
Accessibility Check fail when using TextInputLayout. However, doing the things mentioned in that post did not work for me on the latest version of Android.

Automatically show text of error in EditText

I'm using code like
EditText.setError("Something went wrong");
to show an error on an EditText. But only the exclamation mark icon is shown, not the text of the error. Clicking on it shows the error text.
How can I have the error text display automatically, without needing to touch the icon first?

You can set focus to the EditText so that the user doesn't have to click on it.
editText.requestFocus()
However, this would still only show one error at a time. I believe this is probably still the best way to go since that's the way the platform implements it.

// In you layout Xml
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:id="#+id/layFName"
android:textColorHint="#color/edittext_hintcolor"
app:hintTextAppearance="#style/TextAppearence.App.TextInputLayout"
android:layout_height="wrap_content">
<EditText
android:id="#+id/et_name_registration"
android:inputType="textPersonName"
android:hint="Hint Text"
/>
</android.support.design.widget.TextInputLayout>
// In java
private TextInputLayout mLayFName;
mLayFName = (TextInputLayout) findViewById(R.id.layFName);
for set error
mInputLayoutView.setError(msg);
EditText.getBackground().setColorFilter(getResources().getColor(R.color.red), PorterDuff.Mode.SRC_ATOP);}

EditText added is not a TextInputEditText. Please switch to using that class instead

I'm using an EditText inside a TextInputLayout, but after upgrading the support library to 23.2.0, I get this warning in the logcat, What's the difference between a regular EditText and a TextInputEditText? I can't seem to find any documentation for it.

I was wondering this too, Daniel Wilson gathered the documentation, but to the untrained eye it doesn't mean much. Here's what it's all about: "extract mode" is referring to the type of view that's shown when the space is too small, for example landscape on a phone. I'm using Galaxy S4 with Google Keyboard as input method editor (IME).
Landscape UI without visible IME
Based on the focus (on Description) you can see TextInputLayout in action pushing the hint outside the editor. Nothing special here, this is what TextInputLayout is supposed to do.
Landscape UI editing empty Name field
Editing the Name you can see that the IME doesn't give you a hint of what you're editing.
Landscape UI editing empty Description field
Editing the Description you can see that the IME gives you a hint of what you're editing.
Layout XMLs
The difference between the two fields is their type EditText VS TextInputEditText. The important thing here is that TextInputLayout has the android:hint and not the wrapped EditText, this is the case when TextInputEditText's few lines of Java code makes a big difference.
Name field
<android.support.design.widget.TextInputLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Item Name"
>
<EditText
android:id="#+id/name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</android.support.design.widget.TextInputLayout>
Description field
<android.support.design.widget.TextInputLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Item Description"
>
<android.support.design.widget.TextInputEditText
android:id="#+id/description"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="textMultiLine"
android:minLines="4"
android:scrollbars="vertical"
/>
</android.support.design.widget.TextInputLayout>

There is no documentation for it, but the class is a regular EditText with a single extra feature:
Using this class allows us to display a hint in the IME when in 'extract' mode.
Specifically it sets the EditorInfo.hintText. You'll notice in the TextInputLayout class you can specify the hint and it's appearance rather than as part of the child EditText widget.
If you need to do that, you should use a TextInputEditText so it pays attention to the hint info you specified in the TextInputLayout.

They are essentially the same thing, but I think the TextInputEditText has more features and possibly attributes. I changed to the TextInputEditText and everything worked and looked as it did before with the standard EditText.

The only difference is that when your device is in landscape mode, TextInputEditText will show the hint, EditText won't.

I had this problem and just deleted this line in my xml file:
android: fitsSystemWindows = "true"
and the error disappeared.

Meaning of "No label views point to this text field" warning message

What is the meaning of this warning?
No label views point to this text field with an android:labelFor="#
id/# id/editText1" attribute
Note that the double id (#id/#id) is a problem with the error message text and does not reflect the XML content (which is the correct syntax).

The labelFor is an attribute for accessibility options. You assign this to a label so that if, on a form , user clicks a textedit field , android can know what to read (TalkBack) to user.
The id you assigned to it doesn't seem to be a valid one. why there are two #id in the id? Use ids like this: #id/editText1

I've had the same warning message. It disappeared, when I added a hint to my EditText
android:hint="Some explanation about the input..."

Although I am not familiar with the exact error you have posted. But it definitely sounds like you have done something wrong with the id in the textView. Use id like following in your textView.
android:id="#+id/editText1"
And if you want to set labelFor then use :
android:labelFor="#+id/editText1"

It means that you probably should define a label for this edit text and link them using a labelFor inside that labels definition.
example code:
<TextView
android:id="#+id/my_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:labelFor="#+id/my_editText" <!--the plus sign goes first in the code-->
android:text="I'm a label" />
<EditText
android:id="#id/my_editText" <!--no plus sign if not the first-->
android:layout_width="wrap_content"
android:inputType="text"
android:layout_height="wrap_content" />
and it's not only for text views.

Remove th first '#id/' , use like
android:id="#+id/editText1"
which is the correct format. Keep going.. Best wishes.. :)

I solved it by writing both attributes:
android:id="#+id/editText1"
android:labelFor="#+id/editText1"

Select the editText, go to Properties, then Label for and enter #id/EditText1

If the XML looks correct and you're in a Graphical Layout mode then it's probably using a later version of the Android rendering layout that doesn't support EditText.
In Eclipse and Android Studio there should be a green Android icon with what API version is rendering the layout. Make sure you're using a non W or Wearable API as Android W APIs don't support the EditText element. (EditText is most likely not supported because virtual keyboard space is limited on those devices).
The rendered preview should support EditText in any API 4.X version without a trailing W.
