Question

Hi I am new to sencha touch development.

trying to run

Please help. Tried posting the same on sencha toch forum was not even published. Let me know any more information required will comment. Have been stuck with this issue from last 2 weeks.

Answer 1

Finally got the solution. The solution was in the posted question itself. Due to frustration did not observe the simple problem.

The problem was bad java path setting

Since was using eclipse to build android application never felt the need to check the class path, as the application would be built by the IDE. But Sencha CMD build process uses command line arguments that is dependent on class path. So set the classpath, path and JAVA_HOME in the environment variable of the machine to jdk 1.6 which solved the problem.

The first clue was in the 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 the existing android sdk installation to run commands on the sdk/tools/android.bat file. The above command creates android skeleton project, using the setting in the config .json file. Since I was using android for a long time I even suspected the installation of android sdk had gone rogue. So installed a newer installation of the sdk from google. But running the build.xml file in the singleton project project produced the same result.

java.lang.UnsupportedClassVersionError: Bad version number in .class file at java.lang.ClassLoader.defineClass1(Native Method)

Some more search from stack overflow, returned the solution.
