Failed to initialize JaCoCo

Hi guys,

I tried to run COSMO in black box mode using a very simple BMI Calculator app (https://f-droid.org/packages/com.zola.bmi/). First, I decompiled the APK using apktool, inserted the debuggable attribute in the AndroidManifest.xml and re-packaged it (https://gist.github.com/nstarke/615ca3603fdded8aee47fab6f4917826). After that, I executed python cli.py com.zola.bmi.apk:

$ python cli.py com.zola.bmi.apk

The instrumenation process looks fine. After that, I had to re-sign the instrumented APK since the installation failed and complained about a stripped signature:

$ adb install -g output_apks/com.zola.bmi.apk
Performing Streamed Install
adb: failed to install output_apks/com.zola.bmi.apk: Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl90500489.tmp/base.apk: META-INF/ANDROIDD.SF indicates /data/app/vmdl90500489.tmp/base.apk is signed using APK Signature Scheme v2, but no such signature was found. Signature stripped?]

I suppose you are using some outdated signing scheme, but I could fix that by using my own keystore and after re-signing the installation succeeded. However, when I try to launch the app on the emulator the app crashes immediately with the following stack trace:

I am using a Nexus_5_API_25 emulator and the un-instrumented APK works as expected. Is this failure known to you? I will try to update to a more recent dex2jar version but since the instrumentation logs looked promising, I thought this was not necessary.
Or do I need to grant some additional permissions in the AndroidManifest.xml?

Thanks in advance.

Error during Java to Dalvik conversion command

command: python .\cli.py path_to_my.apk
(I tried several apps, official and my own. Both got the error below.)

Watch apk instrumented from you

Good morning I apologize for the distrubution.
I wanted to know in what way it was possible to see and magariscarload the source code with its apk of these applications, which have been tested by you.
Awaiting your reply I wish you a good day.

Could not evaluate onlyIf predicate for task ':app:jacocoInstrumenterReport'

Ciao, ho provato il tool e mi sono imbattuto in un problema nella fase finale, ovvero la fase in cui si va a generare il report HTML.
Quando vado a lanciare il comando ./gradlew jacocoInstrumenterReport, ottengo il seguente errore:
`> Task :app:jacocoInstrumenterReport FAILED

FAILURE: Build failed with an exception.

What went wrong:
Could not evaluate onlyIf predicate for task ':app:jacocoInstrumenterReport'.

Could not read path '/Users/francesco/Desktop/coverage'.`

Se puoi servire, lascio anche le informazioni relative al 1) build.gradle (Project :Personal_Health_Monitor), al 2) build.gradle (Module :app) e al file 3) jacoco-instrumenter-coverage.gradle:
1)

Invece le informazioni relative a gradle sono le seguenti:

Ti ringrazio anticipatamente per la disponibilità.

Experimental results and Aligning APK after Signing

Hi, the experimental results link the in the readme are no longer working.
I also noticed that in the code (apk_instrumenter.py) the apk is being signed (with apksigner) before aligning (with zipalign). I saw in apksigner's documentation that you should first align and then sign.
