B4A Library PermissionsManager

PermissionsManager is a library that enables the management of runtime permissions. This library completely replaces the standard RuntimePermissions library with the addition of modern dangerous permissions and special permissions that require approval via the settings application.

This library contains constants for:
  1. Dangerous permissions,
  2. Special permissions.

For both types of permissions, the request principle is the same and is performed via one of the CheckAndRequestPermission methods. Example:
Dangerous:
Dim PM As PermissionsManager
PM.CheckAndRequestPermission(PermissionsManager.DANGEROUS_WRITE_EXTERNAL_STORAGE)
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
'or
'Wait For B4XPage_PermissionResult (Permission As String, Result As Boolean)
If Result Then
    'Allowed
End If
Special:
Dim PM As PermissionsManager
PM.CheckAndRequestPermission(PermissionsManager.SPECIAL_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS)
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
'or
'Wait For B4XPage_PermissionResult (Permission As String, Result As Boolean)
If Result Then
    'Allowed
End If
Of course, all permissions must be declared in the manifest, either automatically or manually.

As of version 1.2, the PermissionsManagerFileProvider class is included in the library. This FileProvider reduces the size of the final application by 0.5MB compared to the standard B4A FileProvider. This is made possible by wrapping the FileProvider class from the androidx.core:core package.

As of version 1.3, the PermissionsManagerFileProvider class is replaced with FileProvider static class module (B4X module).

To use FileProvider add the following lines to the manifest:
Manifest::
AddApplicationText(
<provider
android:name="igolub.permissionmanager.b4a.PMFileProvider"
android:authorities="$PACKAGE$.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
)
CreateResource(xml, provider_paths,
<files-path name="name" path="shared" />
)

  • PermissionsManager
    • Events:
      • ApplicationResumeAllowed
    • Functions:
      • CheckAndRequestPermission (Permission As String)
        Checks whether the application has been granted the specified permission. If not then the user will be shown a dialog asking for permission.
        The Activity_PermissionResult or B4XPage_PermissionResult will be raised with the result (in all cases).
        This method can only be called from an Activity.
      • CheckAndRequestPermission2 (Permission As String, DescriptionDialogText As String, DescriptionDialogTitle As String, DialogCloseButtonText As String)
        Checks whether the application has been granted the specified permission. If not, dialog with specified DescriptionText and Title will be shown in which you can explain to user for what the application requires this permission. After user closes dialog, a default dialog with asking for permission will be shown.
        The Activity_PermissionResult or B4XPage_PermissionResult will be raised with the result (in all cases).
        This method can only be called from an Activity.
      • CheckPermission (Permission As String) As Boolean
        Checks whether the application has been granted the specified permission.
        This method can be called from a Service.
      • GetAllSafeDirsExternal (subFolder As String) As List
        Returns an List with all the external folders available to your application.
        The first element will be the same as the value returned from GetSafeDirDefaultExternal.
        On Android 4.4+ no permission is required to access these folders.
        On older versions only one folder will be returned. You should add the permission as explained in GetSafeDirDefaultExternal documentation.
        SubFolder - A sub folder that will be created for your application. Pass an empty string if not needed.
      • GetSafeDirDefaultExternal (subFolder As String) As String
        Returns the path to the app's default folder on the secondary storage device.
        The path to File.DirInternal will be returned if there is no secondary storage available.
        It is a better alternative to File.DirDefaultExternal. On Android 4.4+ no permission is required to access this folder.
        SubFolder - A sub folder that will be created for your application. Pass an empty string if not needed.
      • IsDangerous (Permission As String) As Boolean
        Check if the permission is Dangerous permission.
      • IsDangerousOrSpecial (Permission As String) As Boolean
        Check if the permission is Special or Dangerous permission.
      • IsSpecial (Permission As String) As Boolean
        Check if the permission is Special permission.
    • Properties:
      • AllPermissionsInManifestFile As List [read only]
        Returns the List of all permissions specified in manifest file. You can use this list to ask for all permissions in manifest at the same time.
        Example: <code>
        For Each permission As String In PermissionManager1.AllPermissionsInManifestFile
        PermissionManager1.CheckAndRequestPermission(permission)
        Wait For Activity_PermissionResult (permission As String, Result As Boolean)
        Next</code>
      • ApplicationResumeAllowed As Boolean
        You can use this property to prevent the application to resume until the permissions requesting process will finish. Before start of permissions requesting process you need to set this value to False. When permissions process is finished, you must set this value to True. PermissionsManager_ApplicationResumeAllowed event will be triggered when you set value to True. Default value is True.
        Example: <code>
        PermissionManager1.ApplicationResumeAllowed=False 'Start preventing Application to resume.
        For Each permission As String In PermissionManager1.AllPermissionsInManifestFile
        PermissionManager1.CheckAndRequestPermission(permission)
        Wait For Activity_PermissionResult (permission As String, Result As Boolean)
        Next
        PermissionManager1.ApplicationResumeAllowed=True 'Stop preventing Application to resume.</code>

        Wait For PermissionsManager_ApplicationResumeAllowed
        End If
        'Rest of the code...</code>

Hi everybody,

When using B4XPages it is necessary to change:

Activity_PermissionResult
to
B4XPage_PermissionResult

Is this also necessary when using this library??

Best regards

For activity project you must use Activity_PermissionResult.
For B4XPages project it is recommended to use B4XPage_PermissionResult (it is delegatet from MainActivity by default).

So, if I DON'T use B4XPage_PermissionResult it "should" work anyway?? .. I have had situations when if I use "Activity_PermissionResult" on a B4XPage Project, the permission is not granted, and everything after that line does not execute!

Just use next lines in your active B4XPage:
Code:
Dim PM As PermissionsManager
PM.CheckAndRequestPermission(PermissionsManager.[your desired permission])
Wait For B4XPage_PermissionResult (Permission As String, Result As Boolean)
If Result Then
    'Allowed
End If
