Dexter - Online Tool For Analysing Android Applications

Dexter - Android App Analyser

Dexter is an online android application analysis framework that is capable of APK dissection and analysis, extracting information about Activities, BroadcastReceivers, and Permissions, Decompilation, and more.

Dexter's features also include:
  • Manifest view and analysis.
  • Class hierarchy/graph view.
  • Examining actual bytecode in a graph-like basic block view.

It is built around a Python Django backend that combines a SQL database with XML caching (obviously for performance reasons).

The following image shows the Dexter framework components:

If the upload is successful, Dexter's analysis sandbox will perform static analysis on the APK.

Note: If the analysis fails or the status never changes, contact DexLabs.

Now let's talk about the Dashboard...

As you can see in the above image, all the created projects are on the left side in the bar. and there are buttons on the top-right to modify it, invite people, delete it or create a new one.

Note: If you don't see the buttons, you don't have the appropriate rights in the project. Please contact the owner.

In the middle of the tab, you can see the members of the selected project and all analyses inside of it.

If you click on an analysis, you will see some more details about it and you can open it in the analysis view or edit the description and title of it.

Analysis View:

This is the basic analysis view. On the top, you have some information about the application itself and diagrams about some internal statistics of the APK like how big are several packages inside the APK compared to each other etc.

Further down there are lists of all used and application-defined permissions with a small description and all activities, services, broadcast receivers and content providers in the application. If you click on an entry, the class diagram will open automatically.

The buttons on the right are for opening the package diagram, a list of classes and strings and an APK file browser to download files from the APK.

If you want to decompile a class diagram, click on the last button in the toolbar (a circled arrow).

The green bubble you see in the above image is a tag. You can tag things inside your analysis to quickly find them later by searching for them. The above one is created by the Autotagger during the analysis.
