| Medium | Application Data can be Backed up[android:allowBackup=true] This flag allows anyone to backup your application data via adb. It allows users who have enabled USB debugging to copy application data off of the device. |
| High | Launch Mode of Activity (com.lexun.sjgs.DefaultAct) is not standard. An Activity should not be having the launch mode attribute set to "singleTask/singleInstance" as it becomes root Activity and it is possible for other applications to read the contents of the calling Intent. So it is required to use the "standard" launch mode attribute when sensitive information is included in an Intent. |
