android sdk manager – find_java.exe or find_java.bat problem and solution

If you are having issues or problems launching the android sdk manager from it’s folder or from Eclipse with ADT plugin with error related to find_java.exe or find_java.bat as unexpected at this time, here is a simple fix or solution. This is a common problem in the Windows version of the sdk that the bat file is setting an incorrect path for your java.exe or javaw.exe file.

1. Go to your android sdk folder, look inside tools,lib

eg. C:\Program Files (x86)\Android\android-sdk\tools\lib

2. Open the find_java.bat file inside this folder

3. look for this line

for /f %%a in (‘%~dps0\find_java.exe -s’) do set java_exe=%%a
if not defined java_exe goto :CheckFailed

4. change it to ( if you are using java se jdk 7, use jre7 instead of jre6)

rem for /f %%a in (‘%~dps0\find_java.exe -s’) do set java_exe=%%a
set java_exe=”C:\Program Files (x86)\Java\jre6\bin\java.exe”
if not defined java_exe goto :CheckFailed

5. look for this other line

for /f %%a in (‘%~dps0\find_java.exe -s -w’) do set javaw_exe=%%a
if not exist %javaw_exe% set javaw_exe=%java_exe%
goto :EOF

6. then change it to

rem for /f %%a in (‘%~dps0\find_java.exe -s -w’) do set javaw_exe=%%a
set javaw_exe=”C:\Program Files (x86)\Java\jre6\bin\javaw.exe”
if not exist %javaw_exe% set javaw_exe=%java_exe%
goto :EOF

7. Basically, you are defining a specific path where your java binary is. Please use your java path if it is different from the example above.

8. Launch your Android sdk again and it should work.

how to create a tcl pcell for laker ic cad software

Quick Code: This post is for integrated circuit cad engineering software for which information are scarce on the internet. Here is a sample tcl code for creating a tcl pcell in Laker ic cad / layout software. The sample pcell is a n transistor device with 3 parameters ( number of gate finger, number of fins and gate length ) in a new 14nm process technology. You may need to change the layer names, purpose and units depending on your techfile. Check the code below or git clone it at git:// or .

#------- Sample N Transistor Tcl Pcell for laker L3 -----------------#
# what:   14nm sample n transistor
# params: 	pc length, number of fins, number of gate
