Android WebView shouldInterceptRequest? I need to intercept android requests. I passed an HTTPClient and implemented shouldInterceptRequest. The doc says If the return value is null, the WebView will continue to load the resource as usud But when I return the value of super or return null it breaks and won't load the webview? Any thoughts? class WebViewClientImpl(val webView: WebView): WebViewClient() { @RequiresApi(Build.VERSION_CODES.LOLLIPOP) override fun shouldInterceptRequest(view: WebView?, request: WebResourceRequest?): WebResourceResponse? { retuen null } } By clicking "Post Your Answer", you acknowledge that you have read our updated terms of service, privacy policy and cookie policy, and that your continued use of the website is subject to these policies.

Reading JSON or text file in resource folder I am developing Kotlin app. I am trying to read text and JSON files which I stored in resource folder(res/raw/file.txt).

Thanks 1 Answer 1 If you want to read a file from res/raw folder you can obtain InputStream by R.raw.yourfile id like this: res/raw InputStream R.raw.yourfile resources.openRawResource(R.raw.yourfile) Or you can open file by Uri: val uri = Uri.parse("android.resource://com.example.your_package/raw/yourfile") val file = File(uri.getPath()); Alternatevily you can put your files in assets/ folder and get InputStream like this: assets/ ...

taskSnapshot.downloadUrl.toString() dont work in Kotlin Code Img I'm trying to follow a tutorial but the part that teaches the value of DownloadURL = taskSnapshot.downloadUrl.toString() does not work anymore. I tried to substitute some options like : DownloadURL = taskSnapshot.downloadUrl.toString() val DownloadURL = taskSnapshot.storage.downloadUrl.toString() Or : val DownloadURL = ImageRef.downloadUrl.toString() But I only get print values such as : com.google.android.gms.tasks.zzu@8a94cv2 and not a valid url. Think we need a little bit more code. What is class is ImageRef since it seems like you don't follow common casing conventions and is probably a val ? – JRomero 2 days ago ImageRef val I inserted an image with a code sample and println.
