Data recovery is the process of retrieving deleted data from the device and thus is a very important concept in forensics. In this chapter, we have seen various techniques to recover deleted data from both the SD card and the internal memory. While recovering the data from a removable SD card is easy, recovering data from internal memory involves a few complications. SQLite file parsing and file carving techniques aid a forensic analyst in recovering the deleted items present in the internal memory of an Android device.
In the next chapter, we will try to understand the forensic perspective and the analysis of Android apps.
