How can I convert a jar file into apk format?

I need to find a way to convert jar file to apk开发者_StackOverflow file. I have reached a road block!

Is the JAR natively made for Android? If not, you'll have to run it in an emulation layer or something like this: http://microemu.blogspot.com/2008/11/running-java-me-applications-on-android.html

Good luck?

I've never tried this tool, but you can give it a go:

If it doesn't work then I think you'll have to use an emulator on the device, or create an apk from source, as expressed by Blender and burpen.

According to this thread on xda-devs, you might be able to use something like this. However, if you have the source for the jar, then you might as well compile the apk from the source. It seems to depend on what the jar was compiled as.

ok, guess the only way around it is to run the application on an android emulator, when that is done, an apk file is automatically generated in the project directory. If the application is not built by using android libraries then the only way to get an apk file is to rewrite the code by using android libraries and run it on an emulator. Bad news for me and some of you.
