android.support.design.widget.TextInputLayout could not be instantiated

Question

I want to integrate android.support.design.widget.TextInputLayout In my android application. I have copied the jar file android-support-design.jar from the sdk to my applications lib folder. I have added below code in my xml file for the Email EditText,

 <!-- Email Label -->
        <android.support.design.widget.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="8dp"
            android:layout_marginBottom="8dp">
            <EditText android:id="@+id/input_email"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="textEmailAddress"
                android:hint="Email" />
        </android.support.design.widget.TextInputLayout>

While add this code in my layout.xml file I am getting an error like,

Exception raised during rendering: com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup
Exception details are logged in Window > Show View > Error Log
The following classes could not be instantiated:
- android.support.design.widget.TextInputLayout (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.

How can i fix this issue...

I'm not sure how the mentioned code produced MockView cannot be cast to android.view.ViewGroup please show the code that uses a mocking library — OneCricketeer

Also, you should use Gradle dependencies rather than jar files. Less problems will arise — OneCricketeer

If you uses AndroidStudio, you should not include android-support-design.jar. Instead, write like below in your build.gradle:

dependencies {
    ...
    compile 'com.android.support:design:24.0.0'
    ...
}

Edit: If this doesn't work you are probably using a different version. In Windows, go to:

[android-sdk]\extras\android\m2repository\com\android\support\design

On Mac:

sdk/extras/android/m2repository/com/android/support/design

This directory holds a number of version folders. Use the latest version on your build.gradle.

add in the build.gradle following this line:

implementation 'com.android.support:design:28.0.0'

and use in the xml file:

 <com.google.android.material.textfield.TextInputLayout
                    android:id="@+id/inputLayoutMobile"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginLeft="@dimen/dimen_20dp"
                    android:layout_marginRight="@dimen/dimen_20dp"
                    android:hint="@string/phone_number"
                    android:visibility="gone"
                    android.support.design:layout_constraintTop_toBottomOf="@+id/inputLayoutAppServerUrl">

                    <com.google.android.material.textfield.TextInputEditText
                        android:id="@+id/edtTxtMobile"
                        style="@style/Style_TextView"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:drawableLeft="@drawable/ic_smartphone"
                        android:drawablePadding="@dimen/dimen_10dp"
                        android:inputType="number"
                        android:singleLine="true"
                        android:scrollbars="vertical"
                        android:text="@={SettingViewModel.mMobileNo}"
                        android:textSize="@dimen/font_13sp" />
                </com.google.android.material.textfield.TextInputLayout>

The dependency your using is part of the Android support library which is now deprecated and no longer supported by Google. Instead, use this:
implementation 'com.google.android.material:material:<version>'
and replace <version> with the latest version from either Google's Maven Repository or MVN Repository

If implementation, compile and api doesn't work try using classpath with latest version of material library you can find latest version on Google's Maven Repository

dependencies {
    .....
    classpath 'com.google.android.material:material:1.4.0-beta01'
    ....
}

there is no relevance of setting id , TextInputLayout is a part of material design library so we need to add the relevant library to get its intellisense autofill in xml.
