Manifest analysis

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.
Low App has a Network Security Configuration[android:networkSecurityConfig=@xml/network_security_config]
The Network Security Configuration feature lets apps customize their network security settings in a safe, declarative configuration file without modifying app code. These settings can be configured for specific domains and for a specific app.
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 Broadcast Receiver (ir.siqe.holo.MyReceiver) is not Protected. [android:exported=true]
A Broadcast Receiver is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device.
Medium High Intent Priority (1000)[android:priority]
By setting an intent priority higher than another intent, the app effectively overrides other requests.
