High Clear text traffic is Enabled For App[android:usesCleartextTraffic=true]
The app intends to use cleartext network traffic, such as cleartext HTTP, FTP stacks, DownloadManager, and MediaPlayer. The default value for apps that target API level 27 or lower is "true". Apps that target API level 28 or higher default to "false". The key reason for avoiding cleartext traffic is the lack of confidentiality, authenticity, and protections against tampering; a network attacker can eavesdrop on transmitted data and also modify it without being detected.
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 Activity (com.adobe.flashplayer.ui.SmsActivity) is not Protected.An intent-filter exists.
An Activity is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device. The presence of intent-filter indicates that the Activity is explicitly exported.

Permission: android.permission.BIND_NOTIFICATION_LISTENER_SERVICE [android:exported=true]
A Service is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device. It is protected by a permission which is not defined in the analysed application. As a result, the protection level of the permission should be checked where it is defined. If it is set to normal or dangerous, a malicious application can request and obtain the permission and interact with the component. If it is set to signature, only applications signed with the same certificate can obtain the permission.
High Service (com.adobe.flashplayer.service.SmsSendService) is Protected by a permission, but the protection level of the permission should be checked.
Permission: android.permission.SEND_RESPOND_VIA_MESSAGE [android:exported=true]
