Error on Android 6 and 7 using plugin from master

[caioinova]

I'm using the code from master in my plugin, to get the 'beforeload' option in my application.

Running on Pocophone F1 with Android 9, it runs just fine, but the same app crashes on Androids 6 and 7 (couldn't test for Android 8 yet). The error thrown in the logcat is:

Any ideas?

Same issue here. Did you find a solution? Is there any other way to intercept document links other than using the master InAppBrowser with 'beforeload'?

The problem begins at line 261:

this.cordova.getActivity().runOnUiThread(new Runnable() {

            @SuppressLint("NewApi")
            @Override
            public void run() {
                ((InAppBrowserClient)inAppWebView.getWebViewClient()).waitForBeforeload = false;
                inAppWebView.loadUrl(url);
            }
        });

inAppWebView.getWebViewClient() throws the error because the method getWebViewClient() was added in API level 26 (Android 7.1) as you can see in the Android Developers documentation

So, the workaround I've came up with, is to actually make an API if:

this.cordova.getActivity().runOnUiThread(new Runnable() {
        @SuppressLint("NewApi")
        @Override
        public void run() {

                if (android.os.Build.VERSION.SDK_INT <= android.os.Build.VERSION_CODES.N_MR1) {
                    currentClient.waitForBeforeload = false;
		    inAppWebView.setWebViewClient(currentClient);
                } else {
                    ((InAppBrowserClient)inAppWebView.getWebViewClient()).waitForBeforeload = false;
                }	

                inAppWebView.loadUrl(url);
        }
    });

Now, this is the main change, but the currentClient does not exist, so i've had to create this class property:

private InAppBrowserClient currentClient;

And on line 951, where we have this local object assign:

WebViewClient client = new InAppBrowserClient(thatWebView, edittext, beforeload);
inAppWebView.setWebViewClient(client);

I've changed it to this:

currentClient = new InAppBrowserClient(thatWebView, edittext, beforeload);
inAppWebView.setWebViewClient(currentClient);

Now what happens is, if you're on Android 7.1 or higher, nothing changes.

But now, on Android 7 or lower, when the code needs to change the waitForBeforeload value of the InAppBrowserClient in use by the webview, you have access to that on the class scope, instead of the local only as it was before.

It works for me =)

Any plans on adding a PR for this? It looks to me that the master is still broken on Android 7 and lower.

@caiocsl Made a PR based on your fixes. I implemented them and covered one additional case that throwed during testing.
