Disabling autosuggestion on WebView?

Question

I have some HTML text inputs into a WebView, and I need to disable the autosuggetions on these inputs from Android, not from HTML (autocomplete=off).

How can I do this?

here is the main link [http://stackoverflow.com/questions/582244/is-there-a-w3c-valid-way-to-disable-autocomplete-in-a-html-form][1] [1]: http://stackoverflow.com/questions/582244/is-there-a-w3c-valid-way-to-disable-autocomplete-in-a-html-form — , Sep 22 '11 at 16:02

This problem vexed me for quite a while but the solution is very simple:

webview.getSettings().setSaveFormData(false);

I wrote about it here:

For when webview already has the data: `WebViewDatabase.getInstance(this).clearFormData();` – Hugh Jeffner Dec 17 '15 at 21:23

The suggested above answers didn't help me. So I found next solution: I just created a simple wrapper for WebView and used it.

public class NoSuggestionsWebView extends WebView {
    public NoSuggestionsWebView(Context context) {
        super(context);
    }

    public NoSuggestionsWebView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public NoSuggestionsWebView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
        InputConnection ic = super.onCreateInputConnection(outAttrs);

        outAttrs.inputType &= ~EditorInfo.TYPE_MASK_VARIATION; /* clear VARIATION type to be able to set new value */
        outAttrs.inputType |= InputType.TYPE_TEXT_VARIATION_WEB_PASSWORD; /* WEB_PASSWORD type will prevent form suggestions */

        return ic;
    }
}

Brilliant! I had the same problem in my app and after applying this, users reported problem solved. — Giorgos Kylafas, Jul 25 '17 at 08:25

In addition to setSaveFormData setting as False, this also helped me

WebView.getSettings().setSavePassword(false);
WebView.clearFormData();

None of the above helped so after extensive search i found this which works perfect on webview as well as normal websites. Text area can be replaced by Input text fields too :)

<textarea class="form-control" id="comments" autocomplete="off" autocorrect="off"  spellcheck="false"></textarea>

A solution of @lpsun in Kotlin.

import android.content.Context
import android.text.InputType
import android.util.AttributeSet
import android.view.inputmethod.EditorInfo
import android.view.inputmethod.InputConnection
import android.webkit.WebView

class NoSuggestionsWebView : WebView {
    constructor(context: Context) : super(context)

    constructor(context: Context, attrs: AttributeSet) : super(context, attrs)

    constructor(context: Context, attrs: AttributeSet, defStyle: Int) : super(context, attrs,
        defStyle)

    override fun onCreateInputConnection(outAttrs: EditorInfo): InputConnection? {
        val ic = super.onCreateInputConnection(outAttrs)

        /* clear VARIATION type to be able to set new value */
        outAttrs.inputType = outAttrs.inputType and EditorInfo.TYPE_MASK_VARIATION.inv()
        /* WEB_PASSWORD type will prevent form suggestions */
        outAttrs.inputType = outAttrs.inputType or InputType.TYPE_TEXT_VARIATION_WEB_PASSWORD

        return ic
    }
}

For Android 5 without Google Play Services see https://stackoverflow.com/questions/41025200/android-view-inflateexception-error-inflating-class-android-webkit-webview/60639991. There is a bug in `appcompat` library, so WebView will crash on these devices. — CoolMind, Mar 27 '20 at 07:45

If it already has the form data then setSaveFormData(false) won't stop it from using it. To clear the database you may have to do the following:

WebViewDatabase.getInstance(this).clearFormData();

I couldn't do this from Android's side, however in adding to the webview's text input spellcheck="false" did the trick.

<textarea spellcheck="false"></textarea>

In Android 8 and above, you should set importance of a textview subclass for system auto-fill feature:

android:importantForAutofill="noExcludeDescendants"

Official reference: Optimize your app for autofill

Furthermore, You might try to delete the "Web Data" sqlite file in data/data/{your-app-package}/app_webview when webview isn't in use for security's sake.
