无法在Android Studio中打开SDK管理器

Question

I am unable to open android sdk manager in android studio i recently downloaded this.when i click this it shows me a pop up : Cannot launch SDK manager. Output:

'"C:\\Users\\suraj\\AppData\\Local\\Android\\ANDROI~2\\sdk\\tools\\lib\\find_java.exe" -s' is not recognized as an internal or external command, operable program or batch file.

ERROR: No suitable Java found. In order to properly use the Android Developer Tools, you need a suitable version of Java JDK installed on your system. We recommend that you install the JDK version of JavaSE, available here: http://www.oracle.com/technetwork/java/javase/downloads

If you already have Java installed, you can define the JAVA_HOME environment variable in Control Panel / System / Avanced System Settings to point to the JDK folder.

You can find the complete Android SDK requirements here: http://developer.android.com/sdk/requirements.html

so can anyone help me .!!! how to overcome this problem I am using windows 7 os

Answer 1

Make sure your environment vars JDK_HOME and JAVA_HOME are set properly to the installed JDK package. AS requires oracle JDK, try to use the latest for your system.

Edit: Check if "java" and "javac" are known as commands in console

Also check if the path to JDK is set in project properties: Right click on project folder -> Open Module settings

Finally try to use / for the envi path instead of \\ which usually is used in windows

Answer 2

I have found a problem with the Android Studio studio.bat file and here it is

    ::------------------------------------------------------
    :: Locate a JDK installation directory which will be used to run the IDE.
    :: Try (in order): ANDROID_STUDIO_JDK, ..\jre, JDK_HOME, JAVA_HOME.
    :: ---------------------------------------------------------------------
    IF EXIST "%ANDROID_STUDIO_JDK%" SET JDK=%ANDROID_STUDIO_JDK%
    IF NOT "%JDK%" == "" GOTO jdk
    IF EXIST "%~dp0\..\jre" SET JDK=%~dp0\..\jre
    IF NOT "%JDK%" == "" GOTO jdk
    IF EXIST "%JDK_HOME%" SET JDK=%JDK_HOME%
    IF NOT "%JDK%" == "" GOTO jdk
    IF EXIST "%JAVA_HOME%" SET JDK=%JAVA_HOME%
    IF "%JDK%" == "" GOTO error

Do you get the problem in the last 2 lines of code?
It seems that if your environmental variable is %JAVA_HOME% the batch file will GOTO error and an error message will be displayed and that's it NO ANDROID STUDIO FOR YOU, even though %JAVA_HOME% contains a valid path but if the environmental variable is something like %ANDROID_STUDIO_JDK% like mine is because I created it myself then it will work

PROPOSED SOLUTIONS

(1) Edit the batch file Where you see this IF EXIST "%JAVA_HOME%" SET JDK=%JAVA_HOME% IF "%JDK%" == "" GOTO error
Change it to this
IF EXIST "%JAVA_HOME%" SET JDK=%JAVA_HOME% IF NOT "%JDK%" == "" GOTO jdk IF "%JDK%" == "" GOTO error
(2) Create an environmental variable named %ANDROID_STUDIO_JDK% as shown here https://kb.wisc.edu/cae/page.php?id=24500
