1. setting android emulator in config file , running without emulator.

the cmd prompt shows sencha cmd tool version , noting happens not prompt returns, waited hours, in build folder 0 kb .apk file present.

1. setting android device in config file , running without emulator. same case 2

have checked installed api version using

android.bat list targets

command, configured , run same api.

any on issue

following application/sdk used sencha touch development on windows xp sp3 machine.

1. sencha cmd v3.1.2.342
2. sencha-touch-2.1.1-gpl / sencha-touch-2.2.1-gpl
3. ruby installed
4. compass , sass plugin ruby installed.
5. jdk1.5.0_11 , java home set in environment variable.
6. eclipse juno android sdk installed. certificate create android.

created skeleton project tried running in crome browser works fine.

created application configuration json file documentation suggested.

below file updated application.

{     "applicationname":"myapp",     "applicationid":"org.amx.myapp",     "bundleseedid":"kpxfepz6ef",     "versionstring":"1.0",     "versioncode":"1",     "icon": {         "36":"resources/icons/icon.png",         "48":"resources/icons/icon.png",         "72":"resources/icons/icon.png"     },     "inputpath":"./",     "outputpath":"../build/",     "configuration":"debug",     "platform":"android",     "devicetype":"universal",     "certificatepath":"../../my-release-key.keystore",     "certificatealias":"",     "certificatepassword":"abc123",     "provisionprofile":"",     "urlscheme":"",     "notificationconfiguration":"",     "sdkpath":"c:/program files/android/android-sdk",     "androidapilevel":"16",     "permissions":[         "internet",         "access_network_state",         "camera",         "vibrate",         "access_fine_location",         "access_coarse_location",         "call_phone"     ],     "orientations": [         "portrait",         "landscapeleft",         "landscaperight",         "portraitupsidedown"     ] } 

please help. tried posting same on sencha toch forum not published. let me know more information required comment. have been stuck issue last 2 weeks.

finally got solution. solution in posted question itself. due frustration did not observe simple problem.

the problem bad java path setting

since using eclipse build android application never felt need check class path, application built ide. sencha cmd build process uses command line arguments dependent on class path. so set classpath, path , java_home in environment variable of machine jdk 1.6 solved problem.

the first clue in line

c:/program files/android\tools\android" create project --target android-15 --name myapp --activity stactivity --path "../build//" --package org.amx.myapp

sencha cmd uses existing android sdk installation run commands on sdk/tools/android.bat file. above command creates android skeleton project, using setting in config .json file. since using android long time suspected installation of android sdk had gone rogue. installed newer installation of sdk google. running build.xml file in singleton project project produced same result.

java.lang.unsupportedclassversionerror: bad version number in .class file @ java.lang.classloader.defineclass1(native method)

some more search stack overflow, returned solution.
