Android SDK manager won t open

Question

So I installed the android sdk for Windows   http   developer android com sdk index html    the installation link    And ran into the path variable problem  So I fixed that by changing  PATH  in enviroment variables to include where my java exe file is located from the JDK     But now when I open the android sdk manager  a cmd-like screen just briefly flashes on for half a second then disappears  I have no idea what s going on and how to get this thing working

I tried all the most popular solutions before and no one worked for me  until I realised that the Android SDK folder must not have any spaces  so I changed it from  C  Android SDK  to  C  Android SDK   As simple as that

There are many reasons as to why the SDK Manager won t open   Rather than trying each one of them blindly  I recommend running the android bat in a command window so you can read the error message and apply the correct fix

I had the same problem  tried setting path variables and everything  What SDK manager needs is not the JDK  but the actual Java SE end user crap  Go to http   www java com en download ie manual jsp locale en and download that  As soon as I finished installing that  it worked like a charm

Also make sure there is not as JRE before your JDK in PATH on Windows   Oracle always stuffs its own JRE into the path before anything else   I had installed Oracle Lite after I installed the android sdk

I installed Android Studio for Mac  I was not able to access the SDK manager through the IDE  It turns out I just had to have my JAVA HOME environment variable set  Once I got this set I was able to launch the SDK manager

Google removed the GUI for SDK starting from version 26  If you re using version 26  try downgrading to version 25  You can still open the SDK from Android Studio   Source  Is GUI for Android SDK manager gone

In the latest version of the Android SDK  running  SDK Manager exe  and or  AVD Manager exe  will not open anymore  Even the  Launch Standalone SDK Manager  link in Android Studio  which can be previously found in Android SDK Settings  is now gone    It is now recommended to perform manual SDK and AVD management inside Android Studio  But for those who do not have an Android Studio or for those who do not like to open Android Studio just to perform SDK management  you can still manage the SDK using the command line tools   tools bin sdkmanager bat  and  tools bin avdmanager bat     This information is available when running  tools android bat   I think this is true for those who currently have Android SDK tooks v25 3 1 and above

Make sure your java bin directory is in your path statement before the windows system32 directory   The SDK Manager uses java and it was finding the one in the system32 folder    In a CMD window  you can run  where java   Don t forget to restart your CMD after changing the path variable for checking

Same problem here  Fixed  I installed the correct Java stuff  all for 64 bit  because my system is x64  and nothing happened  So I went to C  Users  my name  and deleted the directory  android that has been created the first time the SDK ran  apparently with some wrong configuration   Then it worked  You can try that  Delete that folder or just move it to the desktop and run the SDK

There appear to be several ways to launch the SDK Manager    SDK Manager exe in the root of the Android SDK  SDK Manager exe in sdk tools lib of the Android SDK  Window - gt  Android SDK Manager menu in Eclipse android bat in sdk tools of the Android SDK    In my case  it looks like android bat fails on the line   for  f   a in    java exe  -jar lib archquery jar   do set swt path lib   a   As far as what that line is doing    if I manually run    path to java java  -jar lib archquery jar  It successfully returns  x86 64  But when the batch file runs that same command  I don t know why but it fails with the error message   Unable to access jarfile lib archquery jar   So the variable swt path gets set to an empty string   Everything breaks down from there   The batch file sets the correct value for the variable java exe   Others have commonly reported this as a problem  but those workarounds weren t relevant in my case   People have recommended commenting out the problem line by adding REM to the beginning of it  and adding a line to manually set the swt path variable  which is a valid workaround   REM for  f   a in    java exe  -jar lib archquery jar   do set swt path lib   a set swt path lib x86   BUT  the critical issue in my case is that it s choosing to load a jar file from either the lib x86 or the lib x86 64 folder here   At some point  things were getting confused between the BAT file error  a 32-bit JDK  and a 64-bit Android SDK   SO  the workaround in my case was to    Uninstall ALL versions of Java Install the JDK  You can either use the 32-bit Android SDK and install the 32-bit JDK Or use the 64-bit Android SDK and install the 64-bit JDK  But the  bitness  of the JDK should match the Android SDK   It appears that either of the 32-bit or the 64-bit will work on a 64-bit computer  AS LONG AS the JDK bitness matches the Android SDK bitness   Edit  android bat    If using the 32-bit Android SDK JDK  use lib x86   REM for  f   a in    java exe  -jar lib archquery jar   do set swt path lib   a set swt path lib x86  If using the 64-bit Android SDK JDK  use lib x86 64   REM for  f   a in    java exe  -jar lib archquery jar   do set swt path lib   a set swt path lib x86 64     After doing this  I can successfully run the SDK Manager by running android bat  or from the Eclipse menu  but still not by running either of the SDK Manager exe files directly

I recently faced this problem after I installed android emulator using the sdk manager of android studio - which also upgraded my android sdk tools to 26 0 1  as it was a prerequisite - according to the sdk manager of android studio    In my case  I simply replaced the tools folder of android sdk with tools folder from an older android sdk  This downgraded the android sdk tools  but now I can open the sdk manager using SDK Manager exe

I saw answers that provide workaround solutions by hard coding java exe location and x86   x86 64 architecture string in sdk tools android bat  Those are quick solutions but did not solve the fundamental issue that I am actually curious of   The actual problem that I encountered is  the batch script is not able to find another script jar file and thus is failed to proceed  I could say the script was poorly written   After I made the following changes in sdk tools android bat  everything works like a charm   Specifically  I added   dp0    set java exe  call   dp0 lib find java bat if not defined java exe goto  EOF       for  f  delims     a in     java exe   -jar   dp0 lib archquery jar   do set swt path lib   a   Now  try to launch the script and SDK Manager should come out   p s  My installation of OS  Java 8 and Android SDK are fresh and I did not do any of the extra configuration   p s  You may still need to configure PATH environment variable so that the script could find the suitable java exe

I encountered a similar problem where SDK manager would flash a command window and die   This is what worked for me  My processor and OS both are 64-bit  I had installed 64-bit JDK version  The problem wouldn t go away with reinstalling JDK or modifying path  My theory was that SDK Manager may be needed 32-bit version of JDK  Don t know why that should matter but I ended up installing 32-bit version of JDK and magic  And SDK Manager successfully launched
