QUESTION
I recently updated my android studio to Arctic Fox and got an error in my project
...ANSWER
Answered 2022-Mar-17 at 10:30For insecure HTTP connections in Gradle 7+ versions, we need to specify a boolean allowInsecureProtocol as true to MavenArtifactRepository closure.
Since you have received this error for sonatype repository, you need to set the repositories as below:

QUESTION
Android Studio Bumblebee (2021.1.1) was released stably on 25 January 2022 bundled with a new Device Manager (accompanying new support for Android 11+ device debugging over WIFI). I jumped on this stable release, updating from Android Studio Arctic Fox (2020.3.1 Patch 4).
Unfortunately however, since updating, physical devices/handsets don't remain connected to Android Studio for the purpose of debugging. I can confirm that the issue was introduced from Android Studio Bumblebee onwards (occurring in Beta and Canary builds also). I've reproduced the issue on Android Studio Bumblebee (Stable), Chipmunk (Beta), and Dolphin (Canary), but Android Studio Arctic Fox (superseded Stable) continues to work just fine.
The issue occurs soon after opening Android Studio (Bumblebee+) with one of my physical devices connected. Everything appears fine initially and I may even have enough time to deploy my project to the handset, before the device disappears from Android Studio (as if I'd physically disconnected the USB cable from my computer or from the handset itself).
I've tried a fair few things in an attempt to determine a root cause. These include testing:
- With different USB cables.
- With different handsets (both varying makes and models).
- With various versions of the Android Studio IDE (as mentioned above).
- Plugging the USB cables into different USB ports on my computer.
- Rebooting handsets and my computer.
- Restarting Android Studio.
- Invalidating caches and restarting Android Studio.
adb kill-serverthenadb start-server.- Revoking/reaccepting USB debugging authorization.
- Reinstalled build tools/platform tools, and ADB.
- A great number of further possibilities, to no avail.
I searched and read through remotely similar issues, including (but not limited to) these:
- Android Studio Arctic Fox (Adb) - Connected Devices are being disconnected after some time
- Android debugger continually disconnects
This particular comment in one of the above issues clued me onto a possible root cause:
I have been fighting for a few days with adb not seeing my device. After trying many other posted solutions, I discovered that the issue was with Chrome also trying to connect its debugger to a web view. If Chrome is connected using chrome://inspect, then adb seems to disconnect. Quitting Chrome resolves the issue. Then I can connect with Android Studio and then restart Chrome and reconnect. Hope this helps someone else.
However I've been unable to do anything with the above discovery, other than close Google Chrome, and hope for the best. Obviously this isn't an ideal solution. It appears as though the moment Google Chrome shows the connected physical device in the chrome://inspect/#devices page, the physical device promptly becomes unavailable through Android Studio.
I've jumped back to Android Studio Arctic Fox (2020.3.1 Patch 4) for the moment, however this brings with it other issues (my current core project targets the latest SDK version, which requires the updated IDE).
Absolutely any help with this would be insanely appreciated. I've exhausted just about every avenue that I can think of!

Answered 2022-Feb-01 at 17:29I solved the problem by disabling

QUESTION
I'm facing a weird issue. Before I updated my Android Studio, everything went fine in flutter doctor. Once I've updated Android Studio, when I run the doctor, it's showing "Unable to find bundled Java version". I've already downloaded Java installer and installed it on my M1 Mac, but after I restarted, running flutter doctor still shows the same error. The weird thing is, when I uninstall the Arctic Fox version and re-install the older Android Studio version, everything goes fine again when running the doctor. How can I resolve this?

QUESTION
Android Studio updated to the newest Arctic Fox version, after opening a project it prompted me to update the Gradle plug-in, which I did.
Now everytime I try to run an app (with the updated plug-in) the build fails with the next output: Zip file '/home/user/path-to-my-project/app/build/outputs/apk/debug/app-debug.apk' already contains entry 'AndroidManifest.xml', cannot overwrite
Old apps that are not updated to newest plug-in release does not have this problem.
I already tried with this solution but it didn't help.
My build.gradle file looks like this:

In my case it turned out that AndroidManifest.xml was inside the directory that was pointed to by resources.srcDir. Gradle tried to copy the AndroidManifest.xml from that directory into APK where a compiled version was already bundled.

Answered 2021-Sep-03 at 12:11Not just XML preview, the Jetpack Compose preview is also very blurry on my Macbook. I tried the old trick Help > Edit custom properties and add:

But this did not work (maybe it will work on Windows, you can try). Currently I have to revert back to Android Studio 4.2.2 .
QUESTION
Today I updated my Android Studio from the Arctic Fox to Bumblebee 2021.1.1, and I realized my AVD and emulator windows changed a bit. They were on separate windows, now they are on the right side-menu.
I windowed the emulator again to get the old style, but the mobile-phone on the emulator is not separated from the menu. In the older version, I only had the phone as a separate window, I didn't have window bars and side fillers that are marked on the picture below. How can I get rid of them and only get the phone instead of the whole window? I don't want it as "emulator window" but rather plain "phone".
...ANSWER
Answered 2022-Jan-29 at 09:37If you want the old look in Arctic Fox, go to
File->Settings->Tools->Emulator and unselect "Launch in a tool window".
This way it will launch it seperately which is the same as in the old version.
