I find that the readme file says: "It can also record time-stamped trace of executed methods, values of arguments passed at call-sites, values of formal parameters of methods, etc.", but I don't find how to get it?

Would you please to share the configuration for that? Thank you very much!

The ant build command

ant -f frontend/build.xml deploy

returns this error...
ella/frontend/build.xml:73: java.net.MalformedURLException: no protocol:
tomcat/deploy?path=%2Fella&war=%2FUsers%2FAlex%2FDesktop%2FDevelopment%2Fsrc%2Fella%2Fbin%2Fella.war&update=true

I'm running on mac 10.9 and set my tomcat.url=http:///localhost:8080.

I can set up and run tomcat on at this address independently of ella. Do you know what might be causing this error? Thanks!

In server/src/com/apposcopy/ella/server/Server.java near line 131, findMessageBreak is only used to find breaks within newly read data. This might not work all the time, consider the example {...}\r\n|||\r\n{...}\r\n\r\n where ||| indicates the boundary of data read in the first and second time. In this case, findMessageBreak can only find the second message break, and {...}\r\n\r\n{...} will be fed to Gson, causing parsing problems.

A quick fix would be:

int prefix = Math.min(3, offset);
int splitByte = findMessageBreak(buf, offset - prefix, read + prefix);

So that findMessageBreak will be able to also consider at most 3 characters (\r\n\r) before the newly arrived data, which is enough to cover the problematic situations.

Hope this helps.

When I use the command ella.sh i , I got the following error:

Error: Could not find or load main class Testing.ella.bin.ella.server.jar

What could be the reason?

Is there a away to instrument an apk, run it, collect coverage files and analyze them by some scripts? When many apks need to deal with, it is not good to check every result on a web-server.

Thanks a lot

Hi,

Thank you for contributing this useful tool : )

I tried to instrument several popular apps on Google Play and encountered similar problems:

The command line:

Exception in thread "main" java.lang.Error: Error occurred while instrumenting. exit code is 1
    at com.apposcopy.ella.EllaLauncher.instrument(EllaLauncher.java:259)
    at com.apposcopy.ella.EllaLauncher.main(EllaLauncher.java:23)

The log.txt file:

Exception in thread "main" java.lang.Error: Error in repackaging the apk.
    at com.apposcopy.app.App.updateApk(App.java:208)
    at com.apposcopy.ella.Main.main(Main.java:42)

Sample apps for repeating the error(s):

• com.bethsoft.falloutshelter
• com.amazon.mShop.android.shopping

Thanks!

Hi there,

I have tried to built the ella for a few days, however it seems like it is not working. My error is the same as the other issue page:
(#12)

I have tried to build Ella on my Mac and also on a ubuntu server which is running 20.04.

I have installed all the requested environment.

And then I run the ant command on the ella directory, it shows this error message:

However I have set the path for Android.jar and also the android build tool in the ella.settings file

In the last two lines with the path to these two files.

Could anyone please help me solve this problem?

Hello!

• I'm on step "Instrument the app" in yours README.md.

./ella.sh i /home/node1/Downloads/Ella\ -\ IC\ Airton/apks/facebook.apk

• Then a error appears in the terminal:

Unrecognized option: -
Error: Could not create the Java Virtual Machine.

• When I use any command related to "ella.sh", the same error appears.
• I'm using Ella in my PC on Terminal.
• Thanks!

Hi,

When instrumenting the app using "ella.sh i" command, I got an error saying java.io.FileNotFoundException: /home/myname/ella/bin/ella.runtime.dex (No such file or directory). After checking for "ella.runtime.dex" on the respected directory on my PC and on github, I couldnt find the file. An APK was created in the ella-out, although i'm not sure if that was properly instrumented or not.

Can I ignore this error or is there something that I missed?

Thanks
EB

I set exact path of android but still error.

I added the below two lines

It seems that current implementation supports instrumenting only one dex in an app.
