I have run this script "ruby bin/rec.rb target.apk --no-rec -loop" and meet this trouble.
The script is hanging without clicking. What's wrong with it?

Hi, the a3e world

I am a newer to a3e.
I run into a build failure when invoking the depth-first search on an example android app. 
It seems need to customize the "build.xml", can someone give me any instructions?

The log:

• waiting for device -

At last, the a3e tool hangs on the last command line.
Thanks in advance!

Good morning,

I have encountered some problems during the execution of the tool.
More precisely, it is unable to install troyd.apk.
Even if I try to install that app manually using adb install troyd.apk, I get this error: Failure [INSTALL_FAILED_INVALID_APK]
Moreover, there is an exception before the attempt to install the app.
Could anyone help me?
Thanks in advance.

This is the output
out.txt

I observed this issue when the text contains special characters like spaces. To completely eliminate this problem, I modified both the app and cmd.rb to encode texts in Base64 when they are passed through command arguments.

but there has something wrong, how can i solve this?

When trying to run the Depth First Search the "temp" folder in the project is missing causing a crash.

In Troyd app, registering BroadcastReceiver on main activity might cause A3E to hang if the main activity does not remain running throughout the test. To fix this issue, change the following line in Troy.java:

act.registerReceiver(r, new IntentFilter(Intent.ACTION_RUN));

to

getTargetContext().registerReceiver(r, new IntentFilter(Intent.ACTION_RUN));

In the requirements, you should also mention including $ANDROID_HOME/built-tools/[latest_version] in path. The tool complains that it doesn't find aapt otherwise.

https://github.com/tanzirul/a3e#requirements

This was a change introduced in the newer version of the android sdk

Depth first search hangs at the following step:

shell$ adb shell am startservice -n umd.troyd/.Ignite -e AUT <app and activity name>

I am on Mac OSX with the latest version of ruby, ruby gems, and nokogiri installed.

Dear Developer:
I have tried this tool, but I do not know: how to run Targeted exploration?
