I've got an unrooted Coolpad Porto S running on Android 5.1. I tried to ungoogle it but accidentally removed a vital package. The apps I have been trying to reinstall were com.android.vending and com.google.android.webview (I don't have concrete evidence, but after uninstalling it, I am unable to access any browser application like DuckDuckGo or even Steam) by using pm uninstall -k --user 0 APP. I've been trying to install those back using APKs I got from APK Mirror, but if I do through my phone or through adb, they appear in the app list as "Downloaded", however they're also "Not installed for this user". I tried installing them through using adb install -r app.apk command, then going into adb shell mode and using pm install -r --user 0 app.apk, but still the same result. If I don't use the -r option, it just gives me INSTALL_FAILED_ALREADY_EXISTS error. If it helps, upon doing pm enable --user 0 com.android.vending, it gives me Error: java.lang.SecurityException: Permission Denial: attempt to change component state from pid=4418, uid=2000, package uid=10015error. After tinkering about for a bit, I am still having a ton of issues with doing that. If it helps, I found the base apk location for the WebView app. It didn't work trying to pm install -r --user 0 directory, because INSTALL_FAILED_DEXOPT, but I managed to get the crash in logcat.

Not sure if it helps, but here it is. Anyone got any ideas?

I want to add a corporate-managed email in the Gmail app, but it opens a site for authentication that has to be opened in desktop mode. On Android, it's opened in the app's internal browser and I can't switch to the desktop site and can't add the mail. However, on iPhone, it opens Safari in which I can switch to desktop mode, and the email is added successfully. The email can only be added to the Gmail app. I tried rooting my phone, deleting the Gmail app, and adding the account through Settings, but it still opens this internal browser (web view I think).

We have a web application and want to provide an app for it. We use a simple WebViewClient application which opens our web application. This works good. For authentication the web application doesn't use our own site, but an external ID provider, which redirects back to our website after authentication. The session timeout is pretty short due to reglatory reasons, so the user cannot stay logged in for a longer period of time. So we want the user to at least be able to autofill the user/password fields with credentials that are stored on the phone. It seems like I get different behaviours on different devices. For example I have an Android 9 device and there seems to be no possibility to use stored credentials on the login form. A friend has an Android 12 and for him when he enters the password field he has this little key symbol to use stored credentials to autofill the fields by then selecting one of the stored user/password combinations. Also in Android Studio in an emulator I don't get this option in my keyboard to use stored credentials. So my question is. What are the requirements that this is shown on your phone? Is there a way we can set up the app to always allow the possibility to use stored credentials? Please keep in mind that we don't have control over the login page itself, as it is hosted by the Identity provider. So we would need a solution based only in the app itself.

Is it possible to call a Javascript function that exists within a WebView from Tasker? I tried calling a URL on the WebView of "javascript:FUNCTION_NAME()", but that did not seem to work. This is a completely random example. Lets say, from Tasker, that I want to be able to change the background color of the body of the WebView. In the webview, I have the code function ChangeBGColor(NewColor) { document.body.style.backgroundColor=NewColor; } I want to be able to call ChangeBGColor() from Tasker with a color.

I am looking for a solution to block all URLs except a few which are required for my device to function. I have all the root permissions required to make changes. Is there any way we can block all URLs except a list of URLs (approx. 10 URLs) from a common place in android Web-view Framework so that all the Native applications can access the common code and access set of Allowed and Blocked URLs

I want to whitelist some URLs been used by my device and native apps for sync and updates. Other than these few URLs, I wish to block all other URLs being accessed by any chat window and browser. I have my device rooted, and have been looking for a common solution which can be accessed by all native applications and browsers. I have found a solution to override the API "shouldOverrideUrlLoading" in the class WebView Client, but if there are any applications which do not call this WebViewclient and directly calls native APIs (system/netd). I am quite new to the WebView thing, do let me know if anyone has any solutions or suggestions.

I have a custom Rom on my phone and I didn't install Google Chrome; I'm using Firefox instead. However, once in a blue moon there's a site that complains that it doesn't work with Firefox and suggests using Chrome instead. I have Android Webview installed and as far as I know it is a browser engine based on Chromium. I believe that apps that want to show web content use Android Webview for that. Am I right about this? Is there a workaround to open a website using Webview without installing Google Chrome or other browser?

I have a Samsung Galaxy Tab Active2 (SM-T390) tablet with Android 9 and One UI 1.1 and the latest available updates. An app with an WebView looses connection after about six minutes of standby. I tried to disable enrgy saving for the app as well as Chrome and Android System WebView (Chrome and WebView disables each other). This approach does work for another Samsung device with Android 10, but not on Android 9. Is there another app, which I have to exclude from power saving? Or is this a bug in Android or from Samsung?

does anyone know a way to update the WebView system component on KitKat. I'm running 4.4.4, I think people get updates in Google Play in Android 5.0 and above but I would like to update it on KitKat and keep using this OS as it runs smoother for me, I'm sure there is a way to do this, can anyone help? The Webview on KitKat has some horrible bugs.. Thanks!

I am running AOS 6.0.1 (API-23) on a non-rooted phone. It's been working perfectly for months, but one day after updating some apps like [Uber](https://play.google.com/store/apps/details?id=com.ubercab) , [Viber](https://play.google.com/store/apps/details?id=com.viber.voip) or [Windy](https://play.google.com/store/apps/details?id=co.windyapp.android) , I was told that Google Play services need to be updated as well and would not work properly, until then. I then updated Google Play, Google Play services and Android System WebView, but then none of their maps was working, meaning that maps based on Google maps are just showing an empty blank map canvas without any features except the pins. I.e. showing the cars in Uber but no background map. Somehow, after having installed all and everything Google related for my device, the in-app-maps was working again. Unfortunately, I have no recollection or idea what I did at the time that made it work. Unfortunately now, 6 months later, I have the same problem again after some updates but this time I can't get my maps back. Although Googles own Google Maps, always seem to work... Nowadays I always use [apkmirror](https://www.apkmirror.com/) to download, since they show the relevant app variations and are simply better that Google Play Store, which I no longer use. Here for example, is what's shown for Google Play services: ---------- ---------- My device is a "**440**", at least according to the original firmware versions. 1. **What Google related apps are responsible for showing the in-app-maps correctly?** 2. **On what do they depend?** (I.e. How are they related?) ----------

I'm using Xioami MI 9 SE. Over the past day or two, I've started experiencing mysterious crashes on startup with several applications, including a Radio receiver app (local to Israel); Opera occasionally, APKPure; and one or two others. Now, I noticed other people experiences something similar on their Samsung phones, and also a few new items about a multi-app-crash issue: Are your Android apps crashing? You’re not alone. so I thought my situation may be related. However, the workaround suggested at the link doesn't work for me, since MIUI doesn't even show an "Android System Webview" app. So, could it be the same issue? ANd - how do I restore my system to working order? Note: Downloading and installating the latest APKPure version does not seem to resolve the crash.

I have an Android 5.1 device, where I have full root access. For this device I have written a **cordova application** and installed it as a **system app**. It is working good, however the webview-version of Android 5.1 is very old and unfortunately has a few bugs. I know that you can update the webview with the playstore, but unfortunately the device does not have the google apps and therefore I am not able to update the webview with the playstore. So my question is: **How can I update the system webview without google playstore?** I already tried it with a rather naive approach, which unfortunately killed my application: I have downloaded the latest webview.apk from the playstore (https://play.google.com/store/apps/details?id=com.google.android.webview&hl=de) Then I did: adb remount adb push webview.apk /system/webview/ adb reboot Now I get errors when I try to start my cordova application and the app itself doesn't show up anymore: I/CordovaActivity( 1931): Apache Cordova native platform version 6.1.1 is starting D/CordovaActivity( 1931): CordovaActivity.onCreate() E/WebViewFactory( 1931): Failed to list WebView package libraries for loadNativeLibrary E/WebViewFactory( 1931): android.content.pm.PackageManager$NameNotFoundException: com.android.webview E/WebViewFactory( 1931): at android.app.ApplicationPackageManager.getApplicationInfo(ApplicationPackageManager.java:281) E/WebViewFactory( 1931): at android.webkit.WebViewFactory.getWebViewNativeLibraryPaths(WebViewFactory.java:282) E/WebViewFactory( 1931): at android.webkit.WebViewFactory.loadNativeLibrary(WebViewFactory.java:397) E/WebViewFactory( 1931): at android.webkit.WebViewFactory.getProvider(WebViewFactory.java:103) E/WebViewFactory( 1931): at android.webkit.WebView.getFactory(WebView.java:2194) E/WebViewFactory( 1931): at android.webkit.WebView.ensureProviderCreated(WebView.java:2189) E/WebViewFactory( 1931): at android.webkit.WebView.setOverScrollMode(WebView.java:2248) E/WebViewFactory( 1931): at android.view.View.(View.java:3595) E/WebViewFactory( 1931): at android.view.View.(View.java:3689) **How is the correct way to update the webview.apk without google playstore?**

My mom's phone (yes, I know what you're thinking :-) suffered from the webview update glitch yesterday. She thought that for whatever reasons it might have something to do with her credentials, so she set a new password from another device. I know about the fix for that glitch, but can't do much about it using the recommended methods because now she's locked out of her Google account on her phone. Obviously, trying to update her credentials on her phone must bring webview which doesn't work. It does sound like some kind of catch 22 that my very limited knowledge can't help me getting out of. Any help would greatly appreciated, thanks for your attention.

I need to get netlogs for the Android webview used by my application. The chromium describes few steps to do so. It required userdebug build for which I am using emulator. But the commandline flags need to set using webview-command-line . The path /data/local/tmp/webview-command-line doesn't exists. There is nothing inside. /data/local/tmp folder. Can someone please guide me to how set the commandline flags. Regards

I downloaded and installed the latest version of android system WebView from the app store on my android tablet (running 5.0.2). But apps still go on using the old webview version (39.0.0.0). How can I get them to switch ? For info, I've tried disabling the old one, and it get re-enabled when I open an app that uses webview.

In previous versions of Android, in-app browsing was facilitated using WebView (1) . Disabling in-app browsing system-wide could be achieved by uninstalling the WebView app (2) . Recently, an in-app version of Chrome, called Custom Tabs, took over the WebView app (3, 4) . This meant the previous trick no longer worked. How to disable in-app browsing has already been discussed previously (5) . However, the answers included uninstalling Chrome and, thereby, uninstalling Custom Tabs. Is there a way to keep Chrome as the default browser, while also disabling in-app browsing? Clicking on links in certain apps would, then, result in the full Chrome app opening and rendering the webpage.

**Background** The situation is a little bit confusing but with try to explain: I have 2 applications, A and B respectively. Application A has some links which when clicked are supposed to open in application B (or use **external browser** in case application B isn't installed). This is the setup that I prefer as it doesn't use additional data since application B works offline fully. However when application A updated, it no longer allows these links to open in application B (or external) browser, instead it has an **internal browser** which is limited and needs to use data to load the content which is inconvenient. I tried to communicate with the developer and sadly they said older applications were no longer supported hence I am stuck with application A with an internal browser. Is there a way or workaround to at least force the app not to use its internal browser but allow for me to choose a preferred app or browser to open these links?

I think the title sums up pretty good what I am asking but, here is a screen capture of the particular type of in-browser panels I'm wondering about I don't mean the ones android system shows when there is no default app setup. I mean, in the browser itself. I don't imagine they are the same are they ? I've seen the Android dev documentation about "SlidingPaneLayout" which sounds similar. Except, the one I'm interested in is not "dismissable" or "resizable". It actually takes over the flow and darkens the background until the user either selects an option it offers or, swipe kill the browser tab. Are those part of the webwiew? I'm wondering what term I need to look for in order to get the details about those panels. Or, if I am wrong in anyway here, maybe someone could just give me a brief explanation? would be much appreciated Search results on google mostly brought rants about a completely different type of browser notification so I figured i'd try asking here.

I've a phone and tablet running Android 7.0. In both cases I do not use Chrome as my default browser. I believe that the use of Chrome Webview was to reduce resource use by sharing code. Does it make sense, when one is not using Chrome, to disable Chrome and use Android System webview as default?
