Android Question EndCall routine does not work on Android 8.x !?

palmzac · Jul 13, 2018

Hi,

This routine is work perfectly before Android 8.x. The MODIFY_PHONE_STATE permission already put into manifest editor. Would you help me to solve this problem ? Thanks !

B4X:

Dim r As Reflector
r.Target = r.GetContext
Dim TelephonyManager, TelephonyInterface As Object
TelephonyManager = r.RunMethod2("getSystemService", "phone", "java.lang.String")
r.Target = TelephonyManager
TelephonyInterface = r.RunMethod("getITelephony")
r.Target = TelephonyInterface
r.RunMethod("endCall")

This is error message on Android 8.x .

java.lang.SecurityException: MODIFY_PHONE_STATE permission required.

I guess you have set targetsdk to 26.
Are you using Runtimepermissions and request the right permission?

Hi DonManfred,

Thank for your reply !

MODIFY_PHONE_STATE permission does not need Runtimepermissions After I check the B4A permission tool.

What is the content of the manifest editor?
Are you adding the permission here? If not: why?

https://stackoverflow.com/questions...-state-permission-for-apps-ran-on-gingerbread

Looks like this is no longer possible for normal apps. Only Systemapps get this permission.

MODIFY_PHONE_STATE
added in API level 1
public static final String MODIFY_PHONE_STATE
Allows modification of the telephony state - power on, mmi, etc. Does not include placing calls.

Not for use by third-party applications.

Constant Value: "android.permission.MODIFY_PHONE_STATE

Try to USE runtimepermissions and request the permission. Even if you think it is not a dangerous permission.
Based on SO findings it is...

I used the EndCall routine on my project. How to simulate it on Android 8.x ? Would you help me ?

my manifest

It will not work. Your app will never have the MODIFY_PHONE_STATE permission.

palmzac · Jul 15, 2018

Hi Erel,

Thank for you reply ! I know that.

I want to find a alternative.

I found this code on Stackoverflow. How to convert it to B4A code ? Is it possiable ?

B4X:

    TelecomManager tm = (TelecomManager)  context.getSystemService(context.TELECOM_SERVICE);

    if (tm != null) {
        boolean success = tm.endCall();
        // Call was terminated or not.
    }

B4X:

Dim ctxt As JavaObject
ctxt.InitializeContext
Dim tm As JavaObject = ctxt.RunMethod("getSystemService", Array("telecom"))
Dim success As Boolean = tm.RunMethod("endCall", Null))
