when installing different types of applications so that the user can approve or reject them if necessary. These permissions are permissions for accessing different types of resources in the system and devices. In order for the application to work well, it must obtain approvals from the user to access the resources of the system and the device. Android 6 or higher or Marshmallows are different (runtime permissions android 6). To learn about the different types of access permissions in different versions of the Android operating system , it is recommended that you follow this tutorial article.

What is Runtime Permission?

Runtime Permission are actually permissions to access various resources on the device and system that applications need to ask the user during installation and the user to determine their access to system and device resources. Permissions for access to various resources of the system and device, such as: access to, contacts, etc. In other words, it can be said that applications need some resources in order to be able to work properly and perform all the desired operations. Have access to the device and operating system. This is why when installing applications, a list is displayed to the user that includes access to the device resources and the user must approve or reject it if necessary.In versions of Android less than 6 or Android before Marshmallow, when installing applications, a list of device and system resources was displayed to users and the user was asked to approve or reject them to complete the installation or non-installation process. To take. The list that was displayed to the user for approval or rejection contained all the resources in one place and the user had to approve or reject them at the same time, which would be a problem:1- The first case is that the user had two options to choose from. Either had to approve all the resources displayed in the list for the user to install the application or reject them all. In this case, the application would not be installed. Consider, for example, that of all the resources displayed to the user, the user does not want to approve one of those resources and does not want the application to access that resource, in which case he had no choice or all of them should Approved and the application installation process was done or you had to reject all of them and ignore the application installation.2- The second problem that users faced in this case is that users do not read the list carefully because the list displayed is long and all the resources displayed in the list are long and may confirm it. And then get into trouble. For example, suppose a list of resources is displayed to the user to obtain a license, and the user approves it in a hurry without paying attention to it, and the application is installed, then it may be due to inaccuracy and paying attention to the resources and the list displayed by the user will face problems and the information and data of some of their sources will face problems.To solve such problems, when building and presenting a new version of the Android Marshmallow operating system , they set an option for it, Runtime Permission, which does not display long lists when installing applications to obtain permissions, so that the user can easily and accurately Review sources and approve or reject them if necessary.
