android.permission.READ_PHONE_STATE does not work
«
on:
February 12, 2019, 01:03:26 pm »
hi.
I don’t understand why it doesn’t work for me android.permission.READ_PHONE_STATE
Code: Pascal
[Select]
[+]
[-]
procedure
TfrmMain
.
frmMainJNIPrompt
(
Sender
:
TObject
)
;
var
manifestPermissions
:
TDynArrayOfString
;
begin
if
IsRuntimePermissionNeed
(
)
then
// that is, if target API >= 23
begin
ShowMessage
(
'RequestRuntimePermission....'
)
;
////https://developer.android.com/guide/topics/security/permissions#normal-dangerous
SetLength
(
manifestPermissions
,
1
)
;
manifestPermissions
[
1
]
:
=
'android.permission.READ_PHONE_STATE'
;
//from AndroodManifest.xml
Self
.
RequestRuntimePermission
(
manifestPermissions
,
1212
)
;
//handled by OnRequestPermissionResult
SetLength
(
manifestPermissions
,
1
)
;
end
;
end
;
procedure
TfrmMain
.
frmMainRequestPermissionResult
(
Sender
:
TObject
;
requestCode
:
integer
;
manifestPermission
:
string
;
grantResult
:
TManifestPermissionResult
)
;
begin
case
requestCode
of
1212
:
begin
if
grantResult
=
PERMISSION_GRANTED
then
begin
//ShowMessage('Success! ['+manifestPermission+'] Permission granted!!! ' );
if
manifestPermission
=
'android.permission.READ_PHONE_STATE'
then
showmessage
(
'read_call_state_ok'
)
;
end
else
//PERMISSION_DENIED
begin
ShowMessage
(
'Sorry... ['
+
manifestPermission
+
'] permission not granted... '
)
;
end
;
end
;
end
;
end
;
procedure
TfrmMain
.
jTelephonyManager1CallStateChanged
(
Sender
:
TObject
;
state
:
TTelephonyCallState
;
phoneNumber
:
string
)
;
begin
if
state
=
csIdle
then
showmessage
(
'csIdle'
)
;
if
state
=
csRinging
then
showmessage
(
'pause'
)
;
if
state
=
csOffHook
then
showmessage
(
'start'
)
end
;
The application is successfully compiled and installed on the phone. But when I receive an incoming call, not one of the TTelephonyCallState events does not work.
Why?

Hi, RDL!
finally!
Now demo "AppTelephonyManagerDemo1" can handle
"incoming call" when the app is in background....
You, can try the demo "AppBroadcastReceiverDemo2", too!
Thank you!
