Can't uninstall Android Studio

I'm having problems uninstalling Android Studio in Win10, I can't find the uninstall.exe file. I installed it, but I'm not going to use it, after all, so I went to Control Panel>Programs and Features, but when I tried from there it said it couldn't find the uninstall.exe and removed it from the list, I have the Android Studio folders in Program Files and all, but that's it.
I already removed the SDK from the user folder. All that's left is in Program Files. I tried reinstalling but only creates another installation folder under 'Android Studio1'.
Thanks in advance!

Go to C:\Users%username%, and delete .android,
.AndroidStudio(#version-number), .gradle and AndroidStudioProjects
directories if they exist. After that go to
C:\Users%username%\AppData\Roaming and delete the JetBrains
directory.
Just follow Flot2011's directions and restart your PC, and Android Studio is no more on your computer.

This is what I did to resolve this exact issue:
Launch Android Studio.
Upgrade Android Studio to the latest version when prompted.
Delete C:\Program Files\Android\
Download the latest Android Studio installer.
Install the latest Android Studio. This will replace the files removed in step 3, and install a functioning uninstaller.
Run the uninstaller from the Settings app. Make sure to check the user preferences box so that it deletes the files in %userprofile%.
I prefer this approach to manually removing directories because the installers and updaters should get all of them and also address any registry changes that need to be made.

Android studio doesn't start on windows 10

I bought a new laptop and tried to install Android Studio, but It doesn't start.
I set the right path of "JDK_HOME" and "JAVA_Home" in the environment cariables.
Checked if the Java.exe doesn't exist in C:\Windows\System32
When trying to start Android Studio it shows the process in the Task Manager and disappears instantly.
My JDK Version is 1.8.0_121.

You don't need JDK_HOME and JAVA_HOME
delete one of them should solve your problem. android studio might got duplicated configuration.
If problem remains remove android studio and reinstall it.

Error: Please provide a path to the Android SDK

After installing the Android studio and launching it I am getting this error.
I cannot specify the path to the SDK. I have tried giving the path as :C:\Development\Android\android-sdk-windows\platform-tools\" but the path is invalid

Try this:
close this box then
Tools -> Android -> SDK Manager

I encountered this problem when installing Android Studio 3.0.
There was in fact no folder named C:\Users\Your Name\AppData\Local\Android\Sdk after I installed Android Studio. I tried installing the Android command line tools at this location, but android studio did not accept this. (Turns out, the command line tools are not the SDK.)
Managed to fix it by doing a complete uninstall of Android Studio, deleting the C:\Users\Your Name\AppData\Local\Android folder, deleting any Android Studio settings folders (in my case C:\Users\Your Name\.AndroidStudio2.3 and C:\Users\Your Name\.AndroidStudio2.3). After reinstalling and opening Android Studio, it gave me a dialog to download the SDK.
I can think of 2 possible explanations why this worked for me:
Originally, Android Studio was opening a project straight away, which didn't trigger the "download your sdk" dialog. (This no longer occurred since I deleted my Android Studio settings.)
There was some kind of setting that made Android Studio think I already had the SDK downloaded.

Try this - C:\Users\Your Name\AppData\Local\Android\Sdk
Replace Your Name with the name of your PC.

This problem is usual after you update, or reinstall the Android Studio.. Follow these steps-
* Close all the opened project which is opened by default after you started the Android Studio.. and again open the Android Studio, it will direct you towards re-downloading of SDK components from the net (So be sure to have net connectivity at this point)..
* If above step doesn't work, then restart the PC and open Android Studio again..
Hope it will help..

C:\Program Files (x86)\Android\android-sdk
Hope this will work.

I was also stuck with this...i tried everything mentioned above, but could not get through.
Then I was about to uninstall and reinstall the IDE as mentioned above.
When I was about to uninstall, to my surprise, I found Android SDK Tools in control Panel -> Programs and Features, which was the thing I was looking for!
Android SDK Tools in Control Panel -> Programs and features
I didn't know how to find the path of that, because even after searching in my computer, I didn't get it. So, I went on further and clicked on uninstall.
There, I found the path of Android SDK Tools "C:\Program Files (x86)\Android\android-sdk\". I did not uninstall anything.
I linked this path in the dialogue box, the error was gone!
Whoever encounters the same error, should look for the "Android SDK Tools" in the programs and features in control panel, and then go for uninstalling the same.
There you will find the path of the tools folder.
Copy and paste that path, and you shall get through.

When installing Android Studio on my Mac I accidentally cancelled the dialog box that would normally have installed the SDK. To fix this I deleted Android Studio from /Applications, and deleted the following folders:
% cd $HOME
% rm -rf Preferences/AndroidStudio3.4
% rm -rf Logs/AndroidStudio3.4
% rm -rf Caches/AndroidStudio3.4
% rm -rf Application\ Support/AndroidStudio3.4
(Adjust the version number for your version.) I then reinstalled Android Studio and let it guide me through the SDK installation process.

In case anyone get to experience the same weird situation as me:
I had installed Android Studio, had projects saved, but for some reason I had to do reinstall Windows (and during that I deleted my "Android-folder" in ".../local". When you do that, you will encounter the exact same pop up.
No worries, close it and even though it says that it is needed, it's not. You just don't have access to the prior projects. When saving the new one, then everything will be OK.

The problem was solved by downloading the SDK again, in my case I had deleted the SDK folder that was in C:\Users\george\AppData\Local\Android\Sdk, because I deleted it then I had to download the SDK

I just reinstalled Android Studio (everything) C:/user/yourName/.androidStudio.4 and C:/user/yourName/.androidStudio.4.
You dont have to delete your projects folder!

In my case, going to the Settings menu in Android Studio, there I could download the SDK (none were installed) through the "edit" button

I got this error when moving a project from one computer to antother, even though it wasn't an Android project and didn't need an Android SDK.
The solution for me was to open the file local.properties and remove the line that says sdk.dir. Hope this can help someone.

All you need to do is close the project opened in android studio. This error occurs when you reinstall Android Studio. The previous project that you have been working on will be opened by default. Select that folder from file explorer and move into different location and then again launch Android Studio. The SDK installation will begin thereafter.

The Reason that why Android Studio can't install/find SDK automatically:
As I tried many times for reinstalling Android Studio, but each time I faced with this SDK popup. I figured out that after installing, Android Studio seeks for project folder automatically (usually located in C:\Users\Username\AppData\AndroidStudioProject) to syn previous settings, gradle, SDK path, Android Studio Settings etc. When I deleted this folder (if you need your previous projects copy it somewhere for latter replacement) the usual installation has been started after clicking on install.

I just encountered this issue when updating my Android Studio after a couple of years of not using it, and the solution ended up very easy:
I exited the window with the SDK prompt and closed the old project it was trying to open. Once the project was closed, the IDE was able to prompt me with the download window, and there SDK download worked!

Unable to upgrade Android studio in Ubuntu

I am currently using android studio 2.0 but wanted to update it to 2.1 as its been released on the stable channel. Now when I press on "Update & Restart" button ,it downloads the patch and then will exit but wont restart by its own.So I am starting it manually to check if update was successful but it still shows android studio 2.0 and same dialogue "Android studio is ready to update". I did it many times but no success. I am using Linux Ubuntu System 14.04 LTS.

Try the following:
After the patch was downloaded and Android Studio closed, open the terminal
Go to your android studio folder, e.g.
cd ~/android-studio
Go to bin subfolder:
cd bin
Make sure your studio.sh file has run permissions:
chmod +x studio.sh
Run Android Studio from here: ./studio.sh
After that Android Studio will find the patch and install it. Then you may close Android Studio and run it the regular way (whatever way you prefer, I run it from Launcher pad).

I solved this problem. i logged as root user then updated the android 2.0 to 2.1 it worked fine and got updated

I also faced this problem.
In 64 bit machine android studio installed in 2 different version 32bit and 64bit. At the time of update and restart 32bit android studio selected by default.
and when it load 64bit android studio.
To solve this problem please select 64 bit at the time of update and restart.
hope it will work.

As an alternate solution, you can download the Android Studio version that you want to upgrade to directly. For instance, 2.1 is located here:
2.1 # Android Tools
Make sure that you import your old settings. Also, pull your SDK out of the old install folder and point the new installation at it, if necessary. This will ensure consistency across installs.

What you have to do is simple:
Make sure you can run android studio from command line using studio.sh
If you have an open project in android studio go in "File > Close project" and close it
A small window opens up, wait for the notification for the update to appear and click on it
If 3 doesn't work, close android studio, repeat number 1 and 3
Let me know if it works

Start Android studio from /android-studio/bin/studio.sh, and then restart update process

From where do I import settings from previous version of Android Studio?

I was running Droidio (Android Studio) 0.6.1; from there I was not able to update to the newest version (a quantum leap to 0.8); I had to download it separately and install from Windows Explorer. But now the installation process is looking for old settings:
Where it seems to want to take me is here (to the Android folder, I reckon); this is what I see when I mash the "compressed ellipsis" (one dot) button:
...but I'm not sure that is really the right spot; Is it [not]? What is the precise name of the settings file I should be seeking?
UPDATE
I followed Gabriele's directive, and then I got this:
I chose "Use Android Studio's SDK"
And then I got this when trying to rebuild my project, "Error:Execution failed for task ':app:preBuild'. failed to find target android-19 : C:\Users\clay\AppData\Local\Android\android-studio1\sdk"
UPDATE 2
I then opened the SDK Manager and installed what was missing/out of date, and tried to build again.
I got the error, "Failed to refresh Gradle project 'Platypus' Error: Cause: failed to find target android-19: C:\users\clay\AppData\Local\Android\android-studio1\sdk Install missing platform and sync project
The "Install missing platform and sync project" part of the message is a link. I clicked it, accepted the License Agreement.
Once that finished, the build failed again with a similar message: "...failed to find Build Tools revision 19.1.0 Install Build Tools 19.1.0 and sync project"
Again, the "install..." jazz was a link; I clicked it, accepted, and installed...
The next problem child was, "Error:The project is using an unsupported version of the Android Gradle plug-in (0.11.2) Fix plug-in version and re-import project"
Acquiescing to the counsel of the wise old man in "Never Cry Wolf," I endeavored to persevere by clicking "Fix plug-in version and re-import project"
At which point I finally got a successful build.
UPDATE 3
I then ran the project, and it seemed to be running (it said so, and the red square was visible), but no emulator ever appeared.
I opened the AVD Manager, and the device had a warning icon (repairable). I clicked the "Repair" button; it seemed to work - the warning icon disappeared.
But then I got this:
It still won't display an emulator when I Run > Debug App...
It used to be (with Droidio 0.5* to 0.61) that the first time I ran, I would see this:
...and the Emulator would eventually come up; subsequent runs of the app, the Device would be listed at the top (under "Choose a Running Device") - no more, though - it is only at the bottom as shown in the scream shot above, even on subsequent runs of the app...
I reckon I should try "re-creating the AVD's weird, malformed config.ini" but don't savvy just what steps to take to accomplish that.

I used a method to trick the Android Studio to import settings from previous one without exporting the settings and it worked.
Just go to your previous .AndroidStudio\config folder, copy and paste them all to the new one (in my scenario I updated from 1.1 to 1.2 beta) .AndroidStudioPreview1.2
(For preventing any failure, please make a Rar file of your original config,
also, after it works, export it so you can import it if you need it)

Starting with Android Studio 0.8.0 (Beta) its now
/home/{username}/.AndroidStudioBeta
for a *nix environment
UPDATE:
Since Android Studio is now out of beta the settings can now be found in:
/home/{username}/.AndroidStudio

On mac Sierra, Android studio 2.3
/Users/[username]/Library/Preferences/AndroidStudio2.3/

On my Mac, using Android Studio 2.1, the directory is
~/Library/Preferences/AndroidStudio2.1/
that is, not a hidden dir.

For Linux and Android Studio 4.2+, the location is:
/home/[username]/.config/Google/AndroidStudio4.1
assuming you are upgrading from version 4.1.

Contrary to JetBrains' documentation, but according to Configure Android Studio, the configuration is currently under a "Google" folder:
Windows: %APPDATA%\Google\<product><version>
Mac: ~/Library/Application Support/Google/<product><version>
Linux: ~/.config/Google/<product><version>
That's where I found them (the Mac variant).

And in a *nix environment, this will probably be located at /home/[username]/.AndroidStudioPreview

for Android Studio 4.2, Google has moved it to %appdata%\Roaming\Google\AndroidStudioPreview4.2

There is a single point of reference for the location of the settings folder for all Jetbrains IDE's for all OS's:
