### [Learn Android fundamentals](android-app-pentesting/#2-android-application-fundamentals)
* [ ] [Basics](android-app-pentesting/#fundamentals-review)
* [ ] [Dalvik & Smali](android-app-pentesting/#dalvik--smali)
* [ ] [Entry points](android-app-pentesting/#application-entry-points)
* [ ] [Activities](android-app-pentesting/#launcher-activity)
* [ ] [URL Schemes](android-app-pentesting/#url-schemes)
* [ ] [Content Providers](android-app-pentesting/#services)
* [ ] [Services](android-app-pentesting/#services-1)
* [ ] [Broadcast Receivers](android-app-pentesting/#broadcast-receivers)
* [ ] [Intents](android-app-pentesting/#intents)
* [ ] [Intent Filter](android-app-pentesting/#intent-filter)
* [ ] [Other components](android-app-pentesting/#other-app-components)
* [ ] [How to use ADB](android-app-pentesting/#adb-android-debug-bridge)
* [ ] [How to modify Smali](android-app-pentesting/#smali)
### [Static Analysis](android-app-pentesting/#static-analysis)
* [ ] Check for the use of [obfuscation](android-checklist.md#some-obfuscation-deobfuscation-information), checks for noting if the mobile was rooted, if an emulator is being used and anti-tampering checks. [Read this for more info](android-app-pentesting/#other-checks).
* [ ] Sensitive applications (like bank apps) should check if the mobile is rooted and should actuate in consequence.
* [ ] Search for [interesting strings](android-app-pentesting/#looking-for-interesting-info) (passwords, URLs, API, encryption, backdoors, tokens, Bluetooth uuids...).
* [ ] Special attention to [firebase ](android-app-pentesting/#firebase)APIs.
* [ ] [Read the manifest:](android-app-pentesting/#basic-understanding-of-the-application-manifest-xml)
* [ ] Check if the application is in debug mode and try to "exploit" it
* [ ] Check if the APK allows backups
* [ ] Exported Activities
* [ ] Content Providers
* [ ] Exposed services
* [ ] Broadcast Receivers
* [ ] URL Schemes
* [ ] Is the application s[aving data insecurely internally or externally](android-app-pentesting/#insecure-data-storage)?
* [ ] Is there any [password hard coded or saved in disk](android-app-pentesting/#poorkeymanagementprocesses)? Is the app [using insecurely crypto algorithms](android-app-pentesting/#useofinsecureandordeprecatedalgorithms)?
* [ ] All the libraries compiled using the PIE flag?
* [ ] Don't forget that there is a bunch of[ static Android Analyzers](android-app-pentesting/#automatic-analysis) that can help you a lot during this phase.
### [Dynamic Analysis](android-app-pentesting/#dynamic-analysis)
* [ ] Prepare the environment ([online](android-app-pentesting/#online-dynamic-analysis), [local VM or physical](android-app-pentesting/#local-dynamic-analysis))
* [ ] Is there any [unintended data leakage](android-app-pentesting/#unintended-data-leakage) (logging, copy/paste, crash logs)?
* [ ] [Confidential information being saved in SQLite dbs](android-app-pentesting/#sqlite-dbs)?
* [ ] [Exploitable exposed Activities](android-app-pentesting/#exploiting-exported-activities-authorisation-bypass)?
* [ ] [Exploitable Content Providers](android-app-pentesting/#exploiting-content-providers-accessing-and-manipulating-sensitive-information)?
* [ ] [Exploitable exposed Services](android-app-pentesting/#exploiting-services)?
* [ ] [Exploitable Broadcast Receivers](android-app-pentesting/#exploiting-broadcast-receivers)?
* [ ] Is the application [transmitting information in clear text/using weak algorithms](android-app-pentesting/#insufficient-transport-layer-protection)? is a MitM possible?
* [ ] [Inspect HTTP/HTTPS traffic](android-app-pentesting/#inspecting-http-traffic)
* [ ] This one is really important, because if you can capture the HTTP traffic you can search for common Web vulnerabilities (Hacktricks has a lot of information about Web vulns).
* [ ] Check for possible [Android Client Side Injections](android-app-pentesting/#android-client-side-injections-and-others) (probably some static code analysis will help here)
* [ ] [Frida](android-app-pentesting/#frida): Just Frida, use it to obtain interesting dynamic data from the application (maybe some passwords...)
### Some obfuscation/Deobfuscation information
* [ ] [Read here](android-app-pentesting/#obfuscating-deobfuscating-code)
