android - how to run java hello world program in adb shell?

Question

It would be better if detailed commands provided. Thanks!

I can use the method adopted by android am/pm program:

1. create Android.mk and java file
2. compile using mmm
3. put the generated jar to target /data/
4. run it:
# export CLASS_PATH=/data/MyTest.jar
# app_process /data com.android.test.MyTest

It work, but somewhat difficult. I think there must be an easier way using dx/dvz/dalvikvm.

Answer 1

It would be much easier if you used eclipse to wrap all those commands. ADT plugin for eclipse is just great and productive.

Answer 2

Assuming you do mean a Java hello world, and not an Android hello world:

javac Hello.java
dx --dex --no-strict --output=Hello.jar Hello.class
java -jar Hello.jar Hello

Terminal IDE, an app on the market, allows you to do this on the device, or to telnet into the device and then make use of them.
