AllowBackup ----------- Summary: Ensure that allowBackup is explicitly set in the application's manifest Priority: 3 / 10 Severity: Warning Category: Security The allowBackup attribute determines if an application's data can be ba and restored. It is documented at https://developer.android.com/reference/android/R.attr.html#allowBackup By default, this flag is set to true. When this flag is set to true, application data can be backed up and restored by the user using adb ba and adb restore. This may have security consequences for an application. adb backup allo users who have enabled USB debugging to copy application data off of th device. Once backed up, all application data can be read by the user. a restore allows creation of application data from a source specified by user. Following a restore, applications should not assume that the data permissions, and directory permissions were created by the application itself. Setting allowBackup="false" opts an application out of both backup and restore. To fix this warning, decide whether your application should support bac and explicitly set android:allowBackup=(true|false)" More information: https://developer.android.com/reference/android/R.attr.html#allowBackup
