Inflate exception occurs 'androidx.appcompat:appcompat:1.1.0'

Question

I am trying to upgrade my gradle. When i updated the appcompat from 1.0.2 to 1.1.0, my webview didnt work anymore on certain phones. (api 21 and 22).
Is there a smart way to upgrade to 1.1.0 and still make the webview work.

I get an 'android.view.InflateException: Binary XML file line #1: Error inflating class '. I have tried to find a way to update the webview on my emulators. But i really hope for a code that either way fixes the problem, for users that dont update the webview.

my xml:

<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    />

My Activity:

 private WebView mWebView;
    private String state;

    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        try {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.login_webview_activity);

            mWebView = findViewById(R.id.webview);

            mWebView.setWebViewClient(new MyBrowser());

            WebSettings settings = mWebView.getSettings();
            settings.setJavaScriptEnabled(true);
            settings.setDomStorageEnabled(true);

            CookieManager.getInstance().setAcceptCookie(true);
            CookieManager.getInstance().setAcceptThirdPartyCookies(mWebView, true);

            mWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

My error:

WebViewActivity: android.view.InflateException: Binary XML file line #1: Error inflating class android.webkit.WebView

And again- appcompat 1.0.2 works like a charm, but not 1.1.0.

Something might be wrong with your xml. Please share the related xml code too. — Mahdi-Malv, Sep 17 '19 at 07:06
haven't found any solution yet... just ended up with downgrading appcompat again hahah — Meyben, Sep 18 '19 at 07:28
It's a bug in Lollipop + regression in AppCompat 1.1.0, see: https://issuetracker.google.com/issues/141132133 and https://stackoverflow.com/questions/41025200 — gmk57, Sep 19 '19 at 12:41

If you are not relying on DayNight theme switching (or other UiMode events), you can add android:configChanges="uiMode" to the webview activity manifest to prevent AppCompatDelegate updating the Resources configuration and thereby messing up the webview inflation. Found this workaround by studing the sourcecode of the 1.1.0-rc01 to 1.1.0 changes.

Downgrading to 1.1.0-rc01 should also work.
