I have developed a simple android application in which I have used webview to access a webpage.
When I run the application, I get the error saying webpage does not exist or check your internet connection.
I checked the internet connection and also the same link opens in my computer.
Where am I going wrong?
Do I have to provide some special permissions to the application to access the webpage over internet?
What else could be causing this error?
Try adding missing permission in manifest.
<manifest xlmns:android...>
...
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>

Login and Registration aren't working on the apk that we build, but it works on the emulator, and it works when it's connected with a cable to a real phone.
Any ideas?
We haven't changed anything considering login.(controllers, service, ect.) and we are using android phones
We are also using GetX if that matters.
Is it some android permission or something?
You might forget the internet permission in Android Manifest.
in your AndroidManifest.xml file, add the below line inside <manifest></manifest>
<uses-permission android:name="android.permission.INTERNET"/>
Flutter App is working fine with Location Package in Debug Mode but it is not working in Release Mode, the app is not giving location access. i tried to use Flutter Clean Command but nothing Helped. Pls Help me
If your problem is that the flutter build (APK, bundle) isn't making API calls in a real device, this is because you need to add the Internet permission to Android Manifest before creating the release/build.
By default, "internet use" will work fine on the emulator but not on a real device.
To fix this, simply:
Open the file "android/app/src/main/AndroidManifest.xml" and add the proper user-permission
<manifest>
...
<uses-permission android:name="android.permission.INTERNET"/>
...
</manifest>
And then create your build again.
Also there is discussion on github , you can visit their and clearify your problem more effectively Github.
We have an app connected to the internet.
Building a release APK is working and the app is connected to the internet.
Building a App Bundle, uploading it in the Google Play store and
installing it via Google Play the app is running but gets no connection to the internet.
downloading the apk via the App Bundle Explorer in the Google Play Console the app is running but gets no connection to the internet.
I also see the android.permission.INTERNET is set...
What can be the problem in my case?
<application android:label="APP_NAME" android:usesCleartextTraffic="true" //Add This>
</application>
<uses-permission android:name="android.permission.INTERNET"/> //Add This
Few Options I can think of:-
1. Build the apk from aab you uploaded on play. (test its behaviour)
2. Check that the flavor you are building, it doesn’t override settings, by having its own manifest.
3. Test on different devices.
4. See if there are any certificates installed.
5. Reverse Engineering (Last Option)
I found out the problem is not about the connection to the internet itself - the problem seems to be inside the flutter_secure_storage - but only when deployed in Google Play Store...
After updating flutter_secure_storage to the latest version the problem was gone.

Hi guys, I faced with this error and the real problem came from flutter_secure_storage and shared_preferences. You guys need to add:
android:allowBackup="false" android:fullBackupContent="false"
to Androidmanifest.xml like this issues!
There is a manifest file in this directory
android/app/src/debug/AndroidManifest.xml
Copy the internet permission from above directory and to add the internet permission in this directory
android/app/src/main/AndroidManifest.xml
My APK build file in flutter doesn't have internet permission.
I already did this
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.Supplier_app">
<!-- Flutter needs it to communicate with the running application
to allow setting breakpoints, to provide hot reload, etc.
-->
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
This is a very general issue faced by flutter beginners.
In android, each required permission is specified in AndroidManifest.xml file.
For native coding there is only one file inside app/src/main. For flutter, there are not one but 3 of these.
app/src/debug/AndroidManifest.xml - for debug mode
app/src/main/AndroidManifest.xml- for app distribution in release mode
app/src/profile/AndroidManifest.xml - for running app in profile mode
The internet permission is provided by default in the debug mode. So, internet works without doing anything.
All the permissions required for app distribution must be specified in app/src/main/AndroidManifest.xml. For testing purpose, the permissions are specified in other files mentioned.
Please check the mode of the app in which you have permission. It should be in main/AndroidManifest.
You are probably trying to edit the AndroidManifest.xml that is located inside the "debug" directory. The AndroidManifest.xml you are looking for is located in the app\src\main path.
when i run the app i get an error:
“Verify Internet Connection”
Meanwhile my laptop and my mobile device has got internet what could be the problem?
I'm not sure what happen. Have you try add internet permission in AndroidManifest.xml located at android/app/src/main you need to add tag :
<uses-permission android:name="android.permission.INTERNET"/>
