I'm having trouble getting emulators running Android versions prior to API 19 (including 19) to connect to the internet. Emulators running newer versions connect just fine. There's no connection at all, it's not that the app can't access the internet, nothing in the device can. Mobile data is turned on and the 4G (or 3G) icon is showing.
I have tried different devices, but the problem seems to be the Android version itself. I also tried deleting and re-creating the device. Uninstalling and reinstalling the emulator, reinstalling Android studio, reinstalling SDK and tried forcing 3G to no avail too.
Sorry if I'm not being specific enough or providing any more info than this, but I'm not able to do much more and I haven't found anything online that helps me.
Is there any reason for this?
Thanks in advance
Android Studio build
SDK
I had the same issue, so I deleted emulator, than went to sdk manager and
updated sdk platform fot 19 api
updated and installed sdk tools as below:

I have a question about running an app through the emulator on android studio.
My emulator device is able to turn on, but when running the app, install never completes so the app times out. I have tried invalidating cache and restarting, and I have installed the sdk platforms that are the same as the emulators and project, but these changes did not work. My computer cannot install emulator hypervisor driver for AMD processors or intel x86 Emulator accelerator, but I don't think it is necessary for the app to run since my emulator can turn on, right? also, any app has never successfully run on android studio.
The is no code other than the hello world that comes up automatically. This is an empty project with a minimum sdk of api: android 4.1. The device I am using is a pixel 2 with an api of 22. (size on disk 3.5 GB) for tools, I have android SDK build-tools 33, android emulator (31.3.10), and android sdk platform- tools (33.0.3) installed.
I have tried every forum that has the same issue as me but if you think there is one that can help me, please share it thanks.
Android Emulators aren't always the best so expect random failures. This is what I would try:
Make sure the app compiles properly (make sure you see BUILD SUCCESSFUL in your bottom "Build" Tab in Android Studio)
Make sure you have updated Android Studio and Android Emulator, Android Build Tools, SDKs etc.
Create and use a device with a higher API version. Ideally one with Play Store.
Depending on your development machine you might want to try a different architecture (ABI). Try x86 or x86_64 instead of what you've already tried.
In rare cases your existing emulator images get corrupted. Uninstall them in your SDK manager (Show Package Details) and install them again.
If possible try running the app on a real device (follow online instructions to enable USB debugging etc.) to verify the emulator is the problem.
So here's the issue:
Regardless of which Android device I choose, my emulator always looks like the screen's been scratched. When I try to run my app, the screen then becomes so distorted and scratched that it's unrecognizable. I have tried, what I think to be, everything including: deleting all android studio files and redownloading the application and wiping data of each emulator. Regardless of what I do, the screen still ends up looking like that.
Here's the details of my emulator:
I'm using a OSX Yosemite 10.10.5.
How do I fix this?
I had same issue and finally just solved it
try to install Oreo system image (API 27) and use it to create new AVD insted of API 28
I had the same issue with Pie in the emulator. I went to the AVD Manager, clicked Edit for the Pie AVD, clicked advanced settings, found the Graphics and changed it to 'Software'. Then it worked!
Well that is strange indeed. Does it happen with emulators from all API levels?
Have you updated your Android SDK tools to version 27 already? Also, check out the Android Blog post with important SDK tools release notes to help you with the emulator setup. Emulator installation is becoming more and more cumbersome in each SDK release and API level, now they even depend on your type of processor... anyway, if you follow the instructions it should eventually work fine.
I am using android studio 2.3. After I updated my android sdk to the latest version, I noticed that my emulator stopped working. When I try to start the emulator it says "Waiting for target device to come online". But it goes nowhere and the emulator never shows up. After reading some posts, I installed some extra libraries Intel and ARM apis for each version of Android like 5.0, 6.0 but still that did not work. Restarted my machine, IDE, invalidated caches but that did not help.
Try rebuilding your emulator. I had a similar issue when I updated to an earlier version (2.2.2), and removing and rebuilding my emulators did the trick after installing the appropriate apis and packages. Hope this helps.
I am using a MACbook. For one specific emulator its always showing offline. The emulator has a nexus 5 skin and is a api 24 build. When i try another emulator its fine and works. i tried re-creating the emulator. when i run adb devices it says the "unauthorized".
I tried the following:
I went into the developer settings of the emulator and allowed usb debugging if to see if that would help but it did not. this happened after i updated android studio to 2.3. i also tried to wipe user data from emulator. What is going on here ?
UPDATE: THIS IS OCCURRing for my other emualtors above api 22 also . i had to switch to genymotion for now which seems to work fine and shows as online. it has something to do with updating android studio. after i re-installed studio and did not take the 2.3 update, the problem was resolved.
Don't know the exact issue but it appears there are some bugs/issues with the latest updates.
Personally I am seeing my tests fail when run by ./gradlew commands, but not when run via Android Studio IDE.
I experienced your offline issue as well, I found I could at least rectify this by running:
adb kill-server
adb devices

-- UPDATE --
After investigating this one a little more, I found there to be compatibility issues between Qt version 5.7.0 which the new emulator uses, and Ubuntu 14.04 and it's version of Qt. Whatever system you will be using, you will have some version of Qt installed.
I'm guessing this may be the cause/related to the issues you are experiencing.
I was successfully able to fix my system by downgrading the SDK tools from version 25.3.1 to 25.2.3. I don't get the speed improvements of the new emulator, but at least I can run my tests reliably.
Going to try resolve the issues between Qt versions, and will update this if I can get the new emulator to work correctly again.
I had the same problem. I solved it by turning on USB debugging after unlocking developer options of the emulator by clicking 7x on the build number.
I'm developing a taxi order application for Android. Two days ago I got stuck with a problem that I couldn't use Internet on emulator - it refused to work. The cause was in network settings in Windows, but I learned it later. That time I just tried to reinstall Android SDK hoping everyrhing will be repaired. Before that I was working with revision 16. Now I installed revision 20. My Eclipse ADT plugin automatically updated to support newer SDK version.
Now I work without real device and test everything on Android emulator. Today I sent the newest release of my app to my chief but I refused to be installed. The minimal SDK version is 8 (2.2), and the chief has an Android 2.3 device. He tried to install this app onto other two devices. Another 2.3 device also declined apk, but a 2.2 device accepted it. What's the problem? Note that I didn't set max SDK version. I also tried installing and running my application an a 2.3 emulator, everything was fine.
P.S. Problem solved, see Tim's suggestion below.
If he had an old version installed have him try uninstalling that first. My guess is that you got a new debug key and it is failing install due to different keys.
