I just downloaded and installed Android Studio. For whatever reason, it won't open. I've tried running it as administrator, but that doesn't seem to work either. I've also tried uninstalling and reinstalling, but I'm still having this same problem.
On windows open task manager and check if android studio is there.
End the task and start the app again it works like a charm
Figured it out! I'm sure someone will run into this in the future, so here goes.
Even though it found my JDK during installation, it wasn't able to find it when I was trying to open it, for some reason. Simple fix. Add a JDK_HOME environment variable to your system variables. It should contain the path to your JDK's ROOT directory. i.e. c:\Program Files\Java\jdk1.7.0_21\
For me this technique works
Hover on icon, then hover on app
Press right click and select maximize
This link http://tools.android.com/knownissues lists another cause for the launcher malfunctioning.
I quote the link here:
"
On some systems the launcher script does not find where Java is installed. Workaround is to set a variable indicating the location of Java [b/55281]:
Open Start menu > computer > System Properties > Advanced System Properties
In the Advanced tab > Environment Variables, add new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.7.0_21.
Another issue we found is that the launcher script uses an option that is unknown to Java on some system [b/55267]
Open the installation folder of Android Studio (e.g. C:\Programs Files\Android\android-studio, or C:\Users\\AppData\Local\Android\android-studio) and find the "bin" directory in there.
Open a "cmd.exe" (command prompt), cd to the android-studio\bin folder and run "studio.bat". You will most likely see an error: for example b/55267 is about the option -XX:+UseCodeCacheFlushing not being recognized. Report the error, remove the line from the studio.exe.vmoptions or studio64.exe.vmoptions and it should now work.
Apologies for this weak launcher."
OS: Windows 10 64bit
Need to delete below folder and try launch Android Studio again.
C:\Users\your_user_name\AppData\Roaming\Google\AndroidStudio4.1
Source: developer android
I am Installing Android Studio 4.1.1 in my Windows 10 and trying to open as normal as well run as administration both ways but did not open as regular.
When I saw in Task Manager then it was run as a background process then simply I was Endtask it in that background process and re-open. It works for me...!!!
Just add a JDK_HOME variable with the path of your JDK as value and start the IDE again. That's the only thing to do, hope this closes the other questions.
Windows 7 user:
I tried all the above ideas ( adding JDK_HOME, JAVA_HOME environment variables), but the final trick was to run as admin.
If that fails, try "where java" in cmd.exe.
If it lists c:\system32\java.exe first, then rename the file.
(i) Open the folder where android-studio is installed. (C:\Program Files (x86)\Android\android-studio)
(ii)- Right click on the android-studio folder and scroll to properties.
(iii)While in Properties window, click on Security.
(iv)Click the Edit Button
(v) Select User/Admin...or others
(vi)Check "Allow" in front of "Full control"
(vii) Either Apply or Press OK
....At this point you have to wait for it to install....Enjoy!!!
And I use Window 8...!!! So same thing applies to Window 7...wonder why the security on it...
I am on Windows 8 64 bit machine.
I already had JDK installed and jdk.1.7.0 folder was present in C:\Program Files\Java. But path for that folder didn't work. You must have jdk.1.7.xxx folder present on your machine and give that folder as JDK_HOME in Environment variable.
You can take latest JDK version from here
Make sure to choose Windows x64 version. Install JDK and then set your path. For those who are not sure how to set path in Windows 8, I have got following screenshots.
Go to bottom right corner. Click on Settings. Click on PC Info.
Click on Advanced System Setting link on left side.
Click on Environment Variables button. A Winodw will open with 2 listboxes. Click on New button below System variables listbox. New Window will pop up. Provide name as JDK_HOME and path as your path like "C:\Program Files\Java\jdk1.7.0_55". No need to take bin folder into the path.
None of the above mentioned solution worked for me. And there is no studio.bat file in bin directory.
So, I downloaded a 32-bit android-studio for my system (as it is 32bit) from here (official website) and it worked!
PS: The link might be broken in the future, just google for the 32 bit android studio.
(After wasting half a day on it, finally, I got it running)
I am running it on Windows 8.1. Also, I had JDK 1.7.0_13.
I tried the following:
Open Start menu > Computer > System Properties > Advanced System Properties In the Advanced tab > Environment Variables
Add new system variable JAVA_HOME that points to JDK folder, C:\Program Files\Java\jdk1.7.0_13\
Just to be on the safer side, also add new system variable JDK_HOME that points to JDK folder, for example, C:\Program Files\Java\jdk1.7.0_13\
Append new PATH in system variable that points to JDK folder, C:\Program Files\Java\jdk1.7.0_13\
But still it didn't work. Then it struck me that might be, my Java version is old. I downloaded the latest version from here.
I uninstalled JDK 1.7.0_13 and installed version 8 i.e. JDK 1.8.0_131.
Now do all the above steps but, replace the path with C:\Program Files\Java\jdk1.8.0_131\ OR whichever your latest version is.
Success!! Now it works.
In my case, I have existing projects and during trying the opening Android Studio, it just showed me the name of the project.
The thing I did was changing the name of that project and forcing Android Studio to ask me to choose which project at the beginning.
In my case, it was a windows related bug. Android Studio was configured properly and working like a charm, but it was opening in the second disconnected windows.
My solution was to press [Win] + Tab and then choose Android Studio on half of the screen so that it readjusts. Finally, I maximized it and it opened it in the correct screen.
I was able to resolve the same issue by refer to the solution provided in Android Developer Portal,
Studio doesn't start after upgrade
If Studio doesn't start after an upgrade, the problem may be due to an invalid Android Studio configuration imported from a previous version of Android Studio or an incompatible plugin. As a workaround, try deleting (or renaming, for backup purposes) the directory below, depending on the Android Studio version and operating system, and start Android Studio again. This will reset Android Studio to its default state, with all third-party plugins removed.
For Android Studio 4.1 and later:
Windows: %APPDATA%\Google\AndroidStudio Example: C:\Users\your_user_name\AppData\Roaming\Google\AndroidStudio4.1
macOS: ~/Library/Application Support/Google/AndroidStudio Example: ~/Library/Application Support/Google/AndroidStudio4.1
Linux: ~/.config/Google/AndroidStudio and ~/.local/share/Google/AndroidStudio Example: ~/.config/Google/AndroidStudio4.1 and ~/.local/share/Google/AndroidStudio4.1
In my case executing these in the command line worked after ending the Android Studio process in the task manager:
net stop winnat
net start winnat
Check the log file in :
C:\Users\<yourid>\.AndroidStudio<version>\system\log\idea.log
It might give you some clue.
You don't have to reinstall the Android Studio. In my case, I just deleted "C:\Users\User.AndroidStudio3.5" folder. Then Android Studio is opened. The folder contains just personel settings such as your ide theme darcula etc.
I invalidated cache and restartI deleted the Android studio version folder which was C:\Users\User.AndroidStudio3.5 for me and it worked like charm.
What worked for me was simply rebooting the computer. I'm certain that logging off and logging in will work to so the environment variables can refresh on profile level after installation.
Change the JAVA_HOME system environment variable to C:\Program Files\Android\Android Studio\jre
The direct path to installed java may not work sometimes due to version conflict.
I had Android studio crash on my machine crying about ram. Then it just wouldn't start again. Restarting th ecomputer wouldn't help and I know it has nothing to do with Java.
What ended up fixing it was runing Android Studio trough the Start Menu, or the instalation folder and not the pinned icon ...
Make sure you are not using two Languages (Hindi + English) as input method because android studio install required some time stamp and suppose you are using Hindi language that time and letters will not match at the time of opening
Solution is - select primary Language as English while installing Android Studio.
To change steps
press Windows
search word language
remove Hindi Language
then install Android Studio
I edited studio.bat file.
I added actual jdk placement to SET JDK= line at the beginning of file:
SET JDK=C:\\\Program Files\\\Java\\\jdk1.8.0_151
You must upgrade to 4.0.1 version!
The same problem happened with me. Actually my C drive wasn't full still I wanted to install android studio in D drive. The problem was resolved when I deleted it and again installed android studio.
Install it in C drive (You don't have to do anything for that. Actually, just click next...next.. next.. while installing and you are done.
)
Zuhair Naqi's solution is good, but in my case I don't have the option to maximize. So I found another method, because in my case the Android Studio (Bumblebee) does not open every time the windows was updated.
Select right click on the android studio icon, and open some recent project.
A new window will open with the recent project correctly.
You close the window that you couldn't see, and from there you can open projects normally.
I was able to solve it by going to control panel and uninstalling android studio, then restarting the computer so that any running instances would close. Next I deleted the folder
C:\Program Files\Android\Android Studio
Re-installed everything, and everything was working fine.
I've been trying to fix this for the last 48 hours, and it is driving me insane.
My SDK Manager.exe flashes a cmd screen and closes in less than a second.
After much searching, I finally managed to get my SDK Manager to open after adjusting android.bat, and running it as administrator.
But, SDK Manager.exe was not able to find android.bat so I copied it into the android-sdk folder.
SDK Manager.exe is now able to find android.bat, but it is still briefly flashing cmd and then closing.
My PATH variable has my jdk java.exe directory as the first entry, and I have restarted and reinstalled several times.
What is causing this? Why am I able to open the manager from android.bat, but not from the executable?
I am trying to configure Eclipse to use the SDK Manager, but obviously I cannot because the executable refuses to open.
Eclipse is also telling me that adb.exe is missing, and upon checking platforms I have confirmed this. I assume adb.exe will be installed from the SDK Manager?
Edit: After thinking about it, I think the issue may be with the permissions of android.bat. It must be run as administrator in order to work, otherwise if opened regularly it will say "Access is denied".
Is it possible to change this? Looking in the properties of android.bat, I have adjusted my account to have full control. This has not affected the issue, though.
I've experienced this on some machines, but not others. It's a strange problem and I believe it has to do with a path problem in one of the android files (android.bat?).
Why this happens on some installs and not others I have yet to figure out. I've read everything I could find both here and on the interweb, tried many different solutions, including installing another version of JDK 6 and 7, modifying the path variable, adding a JAVA_HOME variable, etc. and none worked.
This worked for me in Windows 7...
1) Add a copy of the "SDK Manager.exe" file INSIDE the SDK folder (so it's next to the tools, platforms, et. al folders) and then run it. You will still see the command window "flash" for a second and then disappear, but be patient and the SDK manager WILL show up.
2) Create a shortcut to this "inside" copy of the SDK Manager.exe and move it where ever you want; it now knows where to go to find the files and works every time. I have a copy on my desktop, but it doesn't matter where you put it.
Note: There's still a problem somewhere, and it may have to do with Google, but it seems to happen to some people regardless of what/when they do an install, while others have no issues at all.
This may not be the answer we need to get Google to fix it, but it works without uninstalling/reinstalling java or the SDK, modifying/adding variables, modifying android.bat, changing your path, running as admin, etc., and the best part is it's easy. It's too bad many of us have wasted hours of time on trying to fix it.
Good Luck!
Note: I added the comment below about x64 machines. It's strange, but when we tried it on one x64 (OS/ADT) machine and it didn't work. I just tried a fresh install of Java 7 x64, and ADT x64 on a machine where it was working with a 32bit install (meaning I now have both 32bit and 64bit installs of Java and ADT on the same machine) and again, it works fine. A brief flash, it goes away, and then the SDK manager opens as expected. The mystery continues. :)
I had the same problem when I updated my android SDK tools to 23.0.2. Spent a lot of time (around 6 hours) messing around trying to find a fix... and I found it, but still not sure how it all works.
It has to do with android.bat file in the tools folder of your android SDK directory, in the lines:
set java_exe=
call lib\find_java.bat
I modified the lines into the following values:
set java_exe=pathwhereyoufindjavaexe
REM call lib\find_java.bat
Basically, two things are done:
Set your java_exe variable to your Java.exe path
Delete, or comment the line: "call lib\find_java.bat"
I commented second line so it DOESN'T re-set my java_exe variable through find_java.bat, and manually set my java_exe variable to where my java.exe file is. If you don't know where (or forgot where) your java.exe is, try using windows search for it.
My path for java.exe is different from the one found using find_java.bat.
My Actual path:
U:\PortableApps\CommonFiles\Java\bin\Java.exe
The path find_java.bat sets it to:
C:\Windows\systems32\java.exe
NOTE:
I figured what path "call lib\find_java.bat" sets the java_exe variable through adding the following command below the line itself:
echo %java_exe%
pause
I'm not sure if this is some sort of permission or access error, or this solution worked only for me since my java JDK is on USB device or such. Well, if anyone else bump into this problem, give my solution a try and see if it works for you guys as well.
I had the same issue!
I had installed the ADT bundle 64-bit, so I downloaded Java 64-bit.
I messed around with paths and things, but the thing that fixed it in the end was installed Java 32-bit.
The easy fix is to install both versions. You can download them manually here.
Good luck!
I don't know if it will solve your problem but make sure you have installed jre and jdk and android sdk for the same bit system (I mean that all three are for 32 or 64 bit systems).
I once had an android problem based on this!
If you use them for one system try to reinstall them.
I had a similar problem and it worked after changing all versions to 64 bit.
Hope I could help you.
When you 'Run as administrator' the current directory gets changed because you are impersonating another user. To prove this put the following line at the top of your bat file:
echo.CD=%CD% & pause
Then execute your bat file as a normal user and observe result.
Now execute bat file via 'Run as administrator' and note that CD has been changed to C:\Windows\system32 (typical).
The fix is simple. Put the following line in your bat file to restore the current directory:
pushd %~dp0
It needs to be before you reference any files/folders. I typically put that line near the top of all bat files that may be 'Run as administrator'. It does not hurt anything if used for older (XP) OS's.
I had same problem with Windows 8.1 64-bit and JDK8. I uninstalled JDK8x64 and installed JDK8i586 and now it works like a charm.
I recently updated to ADT r17. Ever since then, none of the android tools could see java on my system. I could not launch AVD Manager, SDK Manager, Draw-9patch, anything. The only way I could get an AVD to launch was to compile from eclipse without my phone plugged it. Java is still on my system, everything was working perfectly on r16. I can still go into the command line and type java and javac and everything works.
I uninstalled the sdk (by deleting the folder) and am attempting to reinstall it. The installer doesn't even see java. I tried clicking back and next again. No dice. I have in my system variables:
JAVA_HOME C:\Program Files\Java\jdk1.7.0_03\bin
I just did that one after the first failed attempt to reinstall since that's what is recommended on the installer. Did not help. What was working before was:
...F:\Development\Android\android-sdk\platform-tools;C:\Program Files\Java\jdk1.7.0_03\bin;...
I can confirm that at the end of the filepath, in the bin folder, java.exe and all it's other programs are there. I'm downloading the .zip sdk, but I don't think that's going to help much, since none of the tools seem to see java even when extracted. Edit: I can confirm, simply extracting the .zip did not help.
I'm on a 64bit system. Everything was working with r16. Any ideas? Should I go back to r16?
You can reference here: http://code.google.com/p/android/issues/detail?id=28196
I set JAVA_HOME=d:\jdk1.7\jre\ (which is my JDK's directory) to solve this problem.
For whatever reason, adt r17 decided it did not like 64bit Java, even though r16 was fine with it. Installed 32bit java and added that to my path. Everything is fine now.
I updated the Android SDK tools from revision 11 to revision 12, and the emulator now fails to start. When I try to run emulator.exe, I get:
invalid command-line parameter: Files\Android\android-sdk\tools/emulator-arm.exe.
Hint: use '#foo' to launch a virtual device named 'foo'.
please use -help for more information
The path to emulator.exe is C:\Program Files\Android\android-sdk\tools.
How do I fix it?
As was previously suggested, it does seem to be caused by the fact that there is a space in the default installation path of the Android SDK: C:\Program Files\Android\android-sdk\
There are a couple of possible solves, though-
move installation directories to paths that do not contains spaces (as already mentioned)...
but simpler and possibly slightly less cumbersome is simply adjusting the path in Eclipse to use 8-dot-3 directory name(s). Since I'm running Win7, I have two Program Files directories, the second one being "Program Files (x86)" which is where the sdk installed. So the 8-dot-3 path is PROGRA~2. Thus, I simply changed the "SDK Location" value in the Android Preferences in Eclipse from C:\Program Files\Android\android-sdk\ to C:\PROGRA~2\Android\android-sdk\ and everything now works fine.
If you don't know the 8-dot-3 name of your desired path, just fire up a Command Prompt and execute "DIR /X"... the short name will be displayed next to each directory.
Same problem for me, though this is my first time trying to work with Android SDK in general. I believe the problem is with the location of the SDK. Note the "paramater" "Files\Android\android-sdk\tools/emulator-arm.exe." I believe there is a bug in google's code where it doesn't have the directory the SDK is located in in quotes, meaning, if there is a space anywhere in the directory name, it won't work. Can someone with their SDK in a directory with no spaces confirm my theory?
To work around the issue, you can call "C:\Program Files\Android\android-sdk\tools\emulator #foo" from the command line, where "foo" is the name of your emulator.
I got this problem just now, and I found a solution.
My path to the emulator-arm.exe is C:\Program Files\Android\android-sdk\tools. When I try emulator-arm #my_avd from the command line (my_avd is my Android Virtual Device name), it works.
I fixed this problem on Windows XP. Just cut from "C:\Program Files\Android\android-sdk" and paste content directory to "C:\Android\android-sdk". Set my system varaible 'ANDROID_HOME'="C:\Android\android-sdk". Set path to Android SDK in Eclipse as "C:\Android\android-sdk". That's it!
Everything works fine.
Since the cause of this issue is the space within filepath names of the Windows install directory then another workaround is to use the file short names (i.e. 8.3 alias filenames).
Specifically, if root install directory for Android SDK is
c:\Program Files\.. then use c:\PROGRA~1\..
or if
c:\Program Files(x86)\.. then use c:\PROGRA~2\..
You can then launch the SDK Manager via the command-line by running:
start c:\PROGRA~2\Android\android-sdk\tools\android.bat
Fixed in r13. Update your SDK Tools!
I think you are saying you changed the minSDK version of your app and now the emulator wont run...? this is because your emulator is the wrong version... assuming you changed the minSDK of your app correctly, all you need to do is create a emulator with the same SDK version. Open the Android SDK / AVD manager (icon top right of screen next to print token) and create a emulator with minSDK 12.
Moving your Android SDK folder to somewhere that the complete path will be without white spaces will fix the problem.
I also got this problem after updating SDK Tools from revision 11 to 12.
I found it was a problem with a space in the upper directory name where android-sdk-windows resides, then I copied both 'eclipse' and 'android-sdk-windows' directories from my 'Program Files (x86)' to the root of drive D:.
All is solved now!
As an alternative to PROGRA~2 method (which is not working for example in Intellij IDEA), you can create a symlink named, for example, prg to Program Files (run mklink /? from command line to learn how to do it), then run emulator as C:\prg\Android\android-sdk\tools\emulator.exe. Change path to SDK/emulator in your IDE also.
I had a same problem when I setup r12. I found out this problem was caused by blank spaces in the path you setup android SDK. The solution is that you should move the folder of android SDK to a place without spaces, in your case : E:\andriod-sdk or D:\abc\xyz\android-sdk.
I'm trying to run the SDK Samples on the Emulator in Eclipse 3.5.
Most of the time the AVD Manager hangs when I try to create a new AVD.
When I manage to create an AVD and try to start the emulator I get this:
emulator: ERROR: no search paths found in this AVD's configuration
weird, the AVD's config.ini file is malformed. Try re-creating it.
I'm running the latest version of the SDK on Win7 32 bit. Any ideas?
Update:
I think I found the source of the problem. I'm running a Hebrew version of WIN 7. My user name is in Hebrew. Apparently this causes a problem for Eclipse. Once I started to suspect that was the problem, I created a new user on the system called DEV and tried to run the emulator under that user. Went like butter.
You can set the environment variable ANDROID_SDK_HOME. For example:
ANDROID_SDK_HOME=D:\Development\android-sdk\
It helped me. Add this variable to <eclipseFolder>\configuration\.settings\org.eclipse.ui.ide.prefs:
ANDROID_SDK_HOME=D\:\\Development\\android-sdk\\
Stop the process adb.exe and (re)start Eclipse.
The problem here is that my c:\users... path has foreign characters in it "Michael Schøler" - the "ø" being the problem.
This is an ecclipse and/or Android SDK problem.
move c:\Users\YourName\.android\avd\YourAVDName.avd manually to c:\Android\YourAVDName.avd then open c:\Users\YourName\.android\avd\YourAVDName.ini and change path from
path=c:\Users\YourName\.android\avd\YourAVDName.avd to path=c:\Android\YourAVDName.avd
Another rather simple solution to this problem (non-english characters in the AVD's path), is to use the "shortname" of the directories. In my case:
My windows user is "András", so my homedir is C:\Users\András
If you open up a cmd, cd to C:\Users, and issue a "dir /x" command, you will see the "shortnames" of the directories, in my case it is "ANDRS~1".
So you just change the path in the AVD's config file from C:\Users\András\blabla to C:\Users\ANDRS~1\blabla, and voila, it works.
If you have special character in your username do this:
~/.android/avd on OS X and Linux, C:\Documents and Settings\user\.android\ on Windows XP, and C:\Users\user\.android\avd on Windows Vista, 7.
There name.ini and name.avd folder
- copy the folder for example: C:\
- modifiy the path in the .ini to path=C:\name.avd
I had a similar problem because of non-latin letters in my username.
When opening the ini-file in a text editor I found the non-latin characters was wrong. So I just changed the path from
path=c:\Users\YourNa¤%"%¤%%¤me.android\avd\YourAVDName.avd
to
path=c:\Users\YourName.android\avd\YourAVDName.avd
and it worked.
To make sure everything is installed correctly, I recommend you reinstall all the components. To be sure everything goes correctly follow my step by step instructions on my blog.
http://androidcodemonkey.blogspot.com/2010/01/how-to-setup-android-development_23.html
If you follow all the steps you should be good to go!
Good luck.
I had the same error. What I found was that I was missing
ARM EABI v7a System Image.
I fixed it by opening the Android SDK Manager (The tool bar button looks like a little white arrow in a gray box with green android head)
I checked the missing system image and clicked the install button.
See this topic.
I also had the same problem since my username was in Cyrilic letters Димитров.
I change it to a latin alphabet and then it's OK.
You have to use Android tool from sdk\tools folder to move your AVD device to some Folder with no foreign characters in the path.
Just type android move avd -n "nameofdevice" -p "newpath"
For example: android move avd -n HTDDESIRE -p C:\HTCDESIRE
I agree with Zian, something is seriously wrong here and you should consider reinstalling. Also make sure of the following:
1) Make sure your avd folder looks sane. This can be found in the .android directory in your home directory. Look in ~\.android\avd\<name-of-avd>.avd\ and you should see config.ini and userdata.img files, plus an sd image if you created one. Make sure your config.ini looks something like this:
hw.sdCard=yes
hw.dPad=yes
hw.accelerometer=yes
hw.lcd.density=160
skin.name=HVGA
skin.path=platforms/android-1.6/skins/HVGA
hw.trackBall=no
hw.ramSize=256
image.sysdir.1=platforms/android-1.6/images/
Or, if you don't have any custom settings, then it will just consist of this one line:
hw.lcd.density=160
2) Make sure you have the latest version of the ADT Eclipse plugin (v0.95).
3) Also, you really truly shouldn't have any permissions problems within your home directory, but hey, it's Windows -- you never know. So you may want to manually set the permissions to the avd/ folder to read/write/execute, just to be sure.
4) Other than that, reinstall with extreme prejudice!
Try to download again the SDK, unzip it and reinstall through Eclipse.
Be sure to have the last version and have configured all the paths in Eclipse preferences correctly.
If you have installed the Android SDK to a different drive ie not C: then you might need to set the ANDROID_HOME environment variable to the location of the SDK installation
Another consideration I may have overlooked in others answers - I see you mentioned Eclipse 3.5 - consider using 3.5.2 (the current latest version)
May not matter, may have just been omitted by you, either way using the most up to date stuff never hurts.
One way is to don't exit the emulator after running. You edit the program without closing emulator. Do it every time.
This solved it for me on IOS: I looked in the actual .ini file for the device (Nexus-7-inch-tablet.ini) which looked like:
avd.ini.encoding=ISO-8859-1
target=android-17
path=/Users/stevensanborn/.android/avd/Nexus-7-inch-tablet.avd
path.rel=avd/Nexus-7-inch-tablet.avd
and removed and extra return space in the file. Resaved it and worked. Ridiculous.
The solution (that worked for me) was to add the following missing entries in my avd's config.ini:
image.sysdir.2=system-images/android-14/armeabi-v7a/
image.sysdir.1=add-ons/addon-google_apis-google-14/images/armeabi-v7a/
