                mwebView.loadUrl("http://google.com");
              // mwebView.loadUrl("http://invol.co/aff_m?offer_id=699&aff_id=2189&source=deeplink_generator&url=http%3A%2F%2Fwww.motherhood.com.my%2F&aff_sub=LKQ2IVP4&aff_sub2=CHINTHAKA &aff_sub3=BO3DH1NY");

                //force links open in webview only
                mwebView.setWebViewClient(new MyWebviewClient());`

Answer 1

也试试这些选项：

webSettings.setDatabaseEnabled(true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
    webSettings.setAllowFileAccessFromFileURLs(true);
    webSettings.setAllowUniversalAccessFromFileURLs(true);
}
