Disabling Android O auto-fill service for an application

Android O has the feature to support Auto-filling for fields. Is there any way I can disable it for a specific application. That is I want to force my application not to use the auto-fill service.

Is it possible ?

To block autofill for an entire activity, use this in onCreate() of the activity:

getWindow()
  .getDecorView()
  .setImportantForAutofill(View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS);

Is there any better method than this ?

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

Currently there is no direct way to disable the autofill for an entire application, since the autofill feature is View specific.

You can still try this way and call BaseActivity everywhere.

public class BaseActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       disableAutofill();
    }

    @TargetApi(Build.VERSION_CODES.O)
    private void disableAutofill() { 
        getWindow().getDecorView().setImportantForAutofill(View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS);
    }
}

You can also force request autofill this way.

public void forceAutofill() {
    AutofillManager afm = context.getSystemService(AutofillManager.class);
    if (afm != null) {
        afm.requestAutofill();
    }
}

Note: At the moment autofill feature is only available in API 26 Android Oreo 8.0

Hope this helps!

Solution 2

I believe the accepted answer is incorrect:

So I have my own class which is extends the android.support.v7.widget.AppCompatEditText and all I did is overwrote the following method with the following value:

@Override
public int getAutofillType() {
    return AUTOFILL_TYPE_NONE;
}

no other solutions worked, not even android:importantForAutofill=”no”.

getAutofillType() comes from the View class, so it should work for every other class such as TextInputEditText too!

I ran into this too. It turns out the issue was caused by setting the hint text on the EditText nested inside the TextInputLayout.

I did some digging and found this nugget in the 26.0.0 Beta 2 release notes.
Andorid Support Release Notes June 2017

TextInputLayout must set hints on onProvideAutofillStructure()

That led me to try setting the hint on the TextInputLayout instead of the nested EditText.

This resolved the crashing issue for me.
Example:

            <android.support.design.widget.TextInputLayout
                android:id="@+id/textInputLayout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Some Hint Text"
                android.support.design:hintAnimationEnabled="true"
                android.support.design:hintEnabled="true"
                android.support.design:layout_marginTop="16dp">

                <android.support.design.widget.TextInputEditText
                    android:id="@+id/editText"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>

            </android.support.design.widget.TextInputLayout>

Seems to be a bug that needs to be fixed : https://issuetracker.google.com/issues/67675432

In the meanwhile a workaround for now is to disable the AutoFill feature for the whole project.
You can add in the values-v26/styles.xml file the following style or you can edit your BaseEditTextStyle if you are using a specific style for your EditText views.

<style name="App_EditTextStyle" parent="@android:style/Widget.EditText">
<item name="android:importantForAutofill">noExcludeDescendants</item>
</style>

and in the values-v26/themes.xml file you can simply add to the default theme that you are using in your app the items editTextStyle and android:editTextStyle like following :

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
...
<item name="android:editTextStyle">@style/App_EditTextStyle</item>
<item name="editTextStyle">@style/App_EditTextStyle</item>
</style>

this way you can apply this changes for all your EditTexts without needing to change your layout files or Activities (and later on you can easily remove it when the bug is fixed).

Is it possible ?

Not that I am aware of. Certainly, nothing is documented.

Is there any better method than this ?

Not that I am aware of.

Solution 6

In your EditText attributes add android:importantForAutofill="no"
This should be a temporary fix and will only apply to api 26+

Solution 7

Create custom EditText style and set android:importantForAutofill to no.

<style name="EditTextStyleWithoutAutoFill" parent="Widget.AppCompat.EditText">
    <item name="android:importantForAutofill">no</item>
</style>

Then in your activity theme set this style for editTextStyle.

<item name="android:editTextStyle">@style/EditTextStyleWithoutAutoFill</item>

In my case, our app targets sdk version 21 but newer devices (26+) were still popping up the autocomplete. Pretty big problem if the app runs on devices that are shared between people. Using just android:importantForAutofill="no" did not work for me.

The only solution that I found to work in my case was:

<EditText
    android:importantForAutofill="no"
    tools:targetApi="o"
    android:autofillHints="AUTOFILL_HINT_SMS_OTP" ...

The reason I added android:autofillHints="AUTOFILL_HINT_SMS_OTP" was because if you long pressed on the EditText it would still bring up autofill. Basically I told the field’s autofill that it is waiting for a text message that will never be sent. Bit of a hack, I know…

Note: you may have to add xmlns:tools="http://schemas.android.com/tools" to your schemas’ if it is not there already.

Had the same problem with API 28+ and disable Autofill. For me the only solution was to disable long click for my views.

                <com.google.android.material.textfield.TextInputEditText
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:longClickable="false"
                    android:text="@={model.emailAdress}"/>

Solution 10

With reference to Google issue tracker, it has been fixed.

This is fixed on Android 8.1

If any issue persists, please report at Google issue tracker they will re-open to examine.

Note: Use and implement solution 1 because this method fully tested our system.
