Permissions¶
Request runtime permissions without polluting your codebase.
Supported platforms: Android.
The most straightforward way to request runtime permissions on Android is not… straightforward, and that's why there are so many libraries that attempt to make it easier.
If you don't use any library, you end up breaking control flow with all permissions request results
coming in a method you must override from your Activity or Fragment as a couple of two arrays.
That means a lot of code to write, and a lot of ways to mess up.
Splitties Permissions leverages suspending functions, and DialogFragments under the hood, to
make requesting a permission and handling all the result cases a single function call.
Setup¶
If you want to use this dependency without using one of the fun packs,
you can use Splitties.permissions, provided you have refreshVersions added to the project.
For reference, the maven coordinates of this module are com.louiscad.splitties:splitties-permissions.
Included functions¶
Top-level functions:
| Name | Description |
|---|---|
hasPermission |

requestPermission |
Requests the passed permission if needed and returns the result. |
ensurePermission |

ensureAllPermissions |
Requests the passed permissions, taking the user to app details in settings if needed and returns only once all are granted. |
Extension functions:
| Name | Description |

Fragment.requestPermission |
Requests the passed permission if needed and returns the result. |
FragmentActivity.requestPermission |
Requests the passed permission if needed and returns the result. |
Fragment.ensurePermission |
Requests the passed permission, taking the user to app details in settings if needed and returns only once granted. |
Fragment.ensureAllPermissions |
Requests the passed permissions, taking the user to app details in settings if needed and returns only once all are granted. |
FragmentActivity.ensurePermission |
Requests the passed permission, taking the user to app details in settings if needed and returns only once granted. |
FragmentActivity.ensureAllPermissions |
Requests the passed permissions, taking the user to app details in settings if needed and returns only once all are granted. |
Usage¶
The requestPermission is straightforward to use, you just have to write a when expression for
its result, but it doesn't help you handling the 2 following cases:
- You need to ask again after showing the rationale
- You need to take the user to your app details in the settings because they checked the do not ask again checkbox.
That's where the ensurePermission comes handy. It takes several parameters to handle showing the
rationale, and will automatically open the settings pointing to your app details if the user checked
the do not ask again checkbox.
You can see how to easily implement a higher-level overload that suits the UX you want to provide for permissions requests with that example, and you can see how it is used in PermissionsExampleActivity.
