I know there are other topics on this but none of these actually worked for me so i am going to ask it again.
my Androidmanifest.xml does have permission from internet.
I allowed network sharing
Airplane mode is off
it just doesn't seem to work and is pretty frustrating. would like to have some help on this been trying to fix it for 8 hours.
Download and install emulator system again. The system image may contain bugs that why emulator has no internet connection.

I cannot solve this error. The app seems to build just fine but, for some reason, can't seem to connect to the emulator. It always ends with "Lost connection to device" while installing. I also tried it on a physical device, still won't work. I have tried numerous possible solution, but none of them worked.
What I've checked:
Memory enough
No connection problem
flutter doctor -v shows no issues
The problem might be some plugin issue, but I don't know what or how to solve it. It also might be something else. If further code or information is required do let me know. Does anyone know how to solve this issue?
I have two times facing this issue, to fix it sometime it is a bit tricky.
It is coming from 2 possibilities:
Device you are using
Invalid SDK after accidentally updates its version.
But, if the problem is on your device, try this.
Reset the debug authorization on your device
Go to settings > developer options > revoke USB debbuging authorization.
If problem persist.
Check the disable adb auth timeout if it unchecked.
Modify the Logger buffer size to max (Mine is set off before, now it is 8MB, and changing this to 64k is working on small apps, but bigger apps need to log the debug process much bigger so it needs to increase its capacity).
Hope this can helps you mate!
What usually fixes it for me is to close the emulator, go into Android Studio Device Manager and 'Wipe Data' for that emulator. See image:
I know that there are several threads posted about this issue, however I believe my problem to be a bit different:
I have installed Android emulator on my desktop.
When i try to browse internet via the emulator, it works perfect.
But the problem is the apps that i have installed in the emulator are not able to access the internet
i installed whatsapp successfully, the registration screen loads properly, then i entered my mobile number and pressed OK button. I keep getting the following error
Unable to connect. Please check that you are connected to the internet
and try again. Please reboot your phone if your connection problem
persists.
Its very annoying that i have been Googleing the error for weeks now and still havent reached a solution to the problem
I tried bluestacks .. i also reinstalled it as well as emulator several times... it did not help...
1000 thanks to person that helps me solve this issue..:D
Re install emulator
Delete and create the emulator again
Check whether machine is connected to online
Check Android manifest to see whether application has access to internet
These are some common issues.
From this answer:
<manifest xlmns:android...>
...
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>
inside your AndroidManifest.xml
Add 8.8.8.8
on a Mac: System Preferences > Network > DNS
(or equivalent for Windows)
As described here: Android emulator not able to access the internet
I have installed youwave on my laptop at home and downloaded whatsapp, then registered in whatsapp. It worked perfectly without any problem.
Then I tried the same at office and it did not work. But can access the internet thru the browser. I believe that the reason is that at office I'm behind a proxy and not sure if whatsapp uses certain protocols not allowed by office proxy.
ok... i have the same problem.
but i know, what is the best solution till now for bluestacks connection problem.
you have to install proxycap software.
make new proxy rules for bluestacks.
in c/program*86/bluestacks/HD-network.exe
this is the file that you have to make rule for.
whatsapp will work and other apps too.
but still u can't download data using bluestacks.
but yes if you have bluetooth then there is no problem. connect ur phone having internet connection.
and your rule's proxy will allow you to download data. the good thing is that 95% data is downloaded through your wired network(LAN). bluetooth connection of phone just helps you to maintain the server side connected...and now go to google store or wtever u want to download. you are good to go.
and just activate a small data pack on your phone.... thanxx.. hope that would help
one solution can be to disable the gps, just go to advance conf. then to location and turn that off. that worked for me at least.
I am not able to access internet in my emulator. It doesn't even connect to google on emulator browser. I have already checked Settings. Data Enabled checkbox is checked.
I referred to a few SO questions before posting the question.
As this answer suggests, I don't have wifi enabled. So that doesn't seem to be a problem.
As another answer in the same question suggests, I tried giving it in Run configurations, but still nothing is changed.
If someone can give any idea, that will help me a lot.
Note: On my emulator's home screen, 3G appears, but its with grey lines. I think those lines should be white. I might be wrong on this.
add GSM Modem Support to your emulator.
open AVD manager -> your emulator -> Edit.-> Hardware->New->GSM Modem Support.
You should check for http proxy settings in Tools of android sdk Manager in Eclipse.
First, I know this question doesn't exactly belong here, but I'll explain later why I'm asking here instead of on the specific android board.
I'm developing an app, and yesterday I had some problems with sqlite, so I went on to checking how my database looked like. Found out I didn't have the sqlite3 actually installed on my phone, so I followed this answer to install it. I got some problems with the pushing part so I tried to alter the permissions on /system to try and make it work. I basically ran "chmod 7777 /system" on an adb shell. After that I still couldn't push the sqlite to the phone, so I quit the shell and tried to open it again, but I got a no permission error. When I unlocked the phone, every possible app (including system ones) started crashing, one after the other. I freaked out and took the battery off. at that time I had the phone connected through usb to a Ubuntu pc, with no headphones connected. When I turned the phone on again everything seemed to work properly, and I managed to push the sqlite to the system folder without any problem. I thought the problem was over and moved on with debugging and developing.
When I was going home, I was listening to some music with headphones and a friend called me. I answered but couldn't hear anything. I then later discovered that since then I can't hear anything and no one can hear me too. Every other sound related function works fine, except calling. I'm not hearing even that calling beep.
So that's why I'm asking here, as it's actually a question related to developing and coding stuff. Please, if anyone knows what this might be, answer here, I have tried many things to get it working again, but none of them worked. I read it could be a headphone related issue, but that seems to occur only on some motorola phones or something. I have a Galaxy S advance, 3 or 4 months old. I have also tried to change the chmod setting again, to chmod 4755 /system, but it remains the same. I'm getting really desperate here, I don't think customer support can solve this.
As nobody ansered yet, and also I think this is a too specific error for many people to know, I'll report what I did and discovered:
I changed the permissions of all the files in the folders /system and /system/app, not recursively.
A friend later told me UNIX systems sometimes have problem with executing programs that have too many permissions
All the system applications had full 777 permissions.
So I rebooted the device many times, even made a factory reset on it, but nothing seemed to work. So I began changing the permissions again. I tried to change everything to the default permissions (I used a friend device of same model as reference), and when I changed the system/app folder permissions to 755 and rebooted, it worked again!
So for all of you who don't know exactly how chmod and permissions on UNIX works, think twice before start to mess up with it.
