I like to use autofill for smsOTPCode and use the library's

androidx.appcompat:appcompat:1.2.0
com.google.android.material:material:1.1.0
androidx.autofill:autofill:1.0.0

For the right hint I use androidx.autofill.HintConstants.AUTOFILL_HINT_SMS_OTP

 <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="@dimen/scan_address_padding"
            android:gravity="center"
            android:importantForAutofill="yes"
            android:autofillHints="smsOTPCode"
            android:orientation="horizontal"
            tools:targetApi="o">

            <com.google.android.material.textfield.TextInputLayout
                android:id="@+id/textField_validate"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_weight="0.5">

                <com.google.android.material.textfield.TextInputEditText
                    android:id="@+id/sms_validate_text_field"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:textIsSelectable="true"
                    android:hint="@string/ux_checkin_validate_tan_text"
                    android:inputType="numberDecimal"
                    android:maxLines="1"
                    android:nextFocusDown="@+id/validate_tan_button"
                    android:singleLine="true"
                    android:textSize="@dimen/scan_font_size"
                    tools:targetApi="o"
                    tools:text="SMS TAN" />

            </com.google.android.material.textfield.TextInputLayout>

        </LinearLayout>

I have tried different combination with

    android:supportsInlineSuggestions="true"
    android:importantForAutofill="yes"
    android:autofillHints="smsOTPCode"
    tools:autofillHints="smsOTPCode"
    android:autofillHints="AUTOFILL_HINT_SMS_OTP"

No one works. I send an SMS with 'code 1234' but I never get the '1234' in my TextInputEditText.

In some combination I get the receiver phone number as autofill which is total wrong. But in this combination I am able the "code 1234" form the SMS.

If I add android:autofillHints="smsOTPCode" TextInputEditText

<com.google.android.material.textfield.TextInputEditText
                    android:id="@+id/sms_validate_text_field"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:textIsSelectable="true"
                    android:hint="@string/ux_checkin_validate_tan_text"
                    android:autofillHints="smsOTPCode"

                    android:inputType="numberDecimal"
                    android:maxLines="1"
                    android:nextFocusDown="@+id/validate_tan_button"
                    android:singleLine="true"
                    android:textSize="@dimen/scan_font_size"
                    tools:targetApi="o"
                    tools:text="SMS TAN" />

I get the bubble "Autofill code from Message" but if I press the bubble, there is no message (code 1234 or 1234) in my TextInputEditText.

Any suggestion to work with AUTOFILL_HINT_SMS_OTP ?
