Install requirements

Install these requirements before to continue.


From NPM package

Run command:

$  npm install -g dexcalibur

And start Dexcalibur with:

$  dexcalibur

Visit and follow instruction.

Your default port number 8000 is already in use ? Specify a custom port by using --port=<number> like $ dexcalibur --port=9999

Fill the form with the location of your workspace and default listening port, and submit it. The workspace will contain a folder for each application you reverse using Dexcalibur.
Install configuration

Dexcalibur will create the workspace if the folder not exists. A standalone version of android platform tools, APKtool, and more will be downloaded into this workspace. Running install

Once install is done, restart Dexcalibur by killing it and doing (again)

$ dexcalibur

From sources



In most situations, Dexcalibur will automatically start the Frida server on your device. However, there are some cases where Dexcalibur is unable to start it or get its status:

In those case, manually start frida-server on your device (you should adapt the command) :

adb shell su -c "/data/local/tmp/frida-server"

Update / Migrating

From version <= 0.6.x

You are using a previous version of Dexcalibur ?

Follow same steps than a new install, and when you should enter workspace path, enter your current workspace location.

From version >= 0.7

Just by doing:

$  npm install -g dexcalibur

Existing configuration and workspace will be detected automatically.


Dexcalibur fails to start (bad interpreter)

If you get this error message ./dexcalibur: bad interpreter: /usr/bin/node: no such file or directory, ensure nodeJS is installed and the path is good.

If you don’t know the path of the NodeJS interpreter, you can run dexcalibur by this way :

node --max-old-space-size=8192 ./dexcalibur <your params>

The parameter –max-old-space-size is optional but often required with large APKs.
