Suggestion: Android version #214

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This is just a suggestion, but I can't find anywhere better to make it.  Given 
that we're using this tool to make modifications of Android files, sometimes it 
could be very useful to be able to modify them directly from the device itself. 
 Sometimes we don't necessarily have access to a computer for one.  But also 
with Bluetooth keyboards and such it can be almost as easy to do such things 
from the device itself anyway.  Plus it's often really small changes anyway 
(for instance, I'm just using this to modify the pre-defined values for the 
number of volume control steps so I can get actual precise volume control.)

Just use dx on the smali.jar or baksmali.jar, and you can run the resulting dex 
file on a device, using something like terminal emulator.

See

id-with-command for an example of how to run a command-line utility on the 
device

How would you modify, say, the framework.jar this way though?

There would be no difference from the way you would do it from your desktop 
machine. Run baksmali, edit the generated files using <android text editor of 
choice>, reassemble with smali, and replace framework.jar, assuming you have 
root access of course.

Thanks.  I still hold to the recommendation that some sort of actual Android 
version would be really nice though.

I tried that and it doesn't work.  Javac requires "annotation processing" and I 
have no clue what that means to manually do it.  My guess is its methodology 
has changed at some point in the two years since the post linked to above was 
written.

Nope, it still works.

From the help I see that you can specify -proc:only to tell it to do this 
annotation processing whatever that is, but this is the result then:
D:\Android\sdk\sdk\build-tools>"C:\Program Files\Java\jdk1.8.0_05\bin\javac.exe"
 -proc:only Smali.jar
warning: Annotation processing without compilation requested but no processors w
ere found.
error: Class names, 'Smali.jar', are only accepted if annotation processing is e

I have no clue how to specify processors for it or for that matter if this is 
even the right way to do this.

javac is the java compiler. It takes java source code and produces java class 
files. It has no idea what to do with a jar file. (hint: a jar file is just a 
collection of .class files.. you can skip the javac step)

I could have sworn I tried dx first and it gave me an error, but, well, it 
worked this time, so I guess not.  However, the dalvikvm command requires a 
classname -- what do I give it?

It should be org.jf.baksmali.main and org.jf.smali.main
