Lazydroid is a tool written as a bash script to facilitate some aspects of an Android Assessment. It provides some common tasks such as:
- Set the debug flag of an application to true
- Set the backup flag of an application to true
- Re-Build the application
- Re-Sign the application
- Smart log extraction of an application
- Extract the APK of an application installed from Google Play
- Download any mobile folder (/sdcard/, application data folder, other)
- Compare two different snapshots of the same folder
- Insert Frida gadget in the APK (for example when the phone is not or cannot be rooted, and thus Frida server cannot be run)

### Installation
Lazydroid requires Linux or Mac OS to run and the next tools installed:
* apktool
* jarsigner
* adb
* aapt (Android Asset Packaging Tool, part of the SDK)
* your keystore and alias
* Frida Agent (pip install frida)

To run lazydroid.sh the steps would be the following:

```sh
$ git clone
$ #configure the path to the tools (adb, jarsigner, apktool, etc and your favorite shell)
$ cd lazydroid
$ ./getfridalibs.sh #get the last frida libs for Android
$ ./lazydroid.sh
```

### Options
* Set apk to debuggable=true
* Unzip an APK and set the debuggable flag to true.
* Set apk to allowBackup=true
* Unzip an APK and set the allowBackup flag to true (useful to extract the app data folder in non-rooted devices)
* Sign apk
