Malware detection in android application by rigorous analysis of decompiled source code

Android platform implements permissions to guard sensitive information from untrusted apps. Android's permission system agreements an all-or-nothing choice when installing an app in smart phones. However, after permissions are approved by users at installation time, applications can use these permissions with no further restrictions to access personal information. Thus, contemporary years have perceived the detonation of uninvited activities in Android apps. An indispensable part in the resistance is the truthful analysis of Android apps. However, traditional system call based study practices are not suitable for Android based OS, because they are unable to detect serious communications between the application and the Android system. In this paper we have analyzed an android application by a mechanism which rigorously examine the decompiled source code which we will get after reverse engineering the android apk files.
