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 Activity (com.github.shadowsocks.antss.ui.MainActivity) 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.
High Activity (com.github.shadowsocks.tasker.ConfigActivity) 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.
High Activity (com.github.shadowsocks.QuickToggleShortcut) 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.
High Service (com.github.shadowsocks.bg.TileService) is Protected by a permission, but the protection level of the permission should be checked.
Permission: android.permission.BIND_QUICK_SETTINGS_TILE [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 Broadcast Receiver (com.github.shadowsocks.tasker.ActionListener) is not Protected.An intent-filter exists.
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. The presence of intent-filter indicates that the Broadcast Receiver is explicitly exported.
High Activity (com.alipay.sdk.app.PayResultActivity) is not Protected. [android:exported=true]
An Activity is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device.
High Activity (com.alipay.sdk.app.AlipayResultActivity) is not Protected. [android:exported=true]
An Activity is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device.
High Activity (com.github.shadowsocks.UrlImportActivity) 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.
High Broadcast Receiver (com.github.shadowsocks.BootReceiver) is not Protected.An intent-filter exists.
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. The presence of intent-filter indicates that the Broadcast Receiver is explicitly exported.
High Service (androidx.work.impl.background.systemjob.SystemJobService) is Protected by a permission, but the protection level of the permission should be checked.
Permission: android.permission.BIND_JOB_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 (androidx.work.impl.background.gcm.WorkManagerGcmService) is Protected by a permission, but the protection level of the permission should be checked.
Permission: com.google.android.gms.permission.BIND_NETWORK_TASK_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.
