I am working on one project on that project i have to work with the below permission.

<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"
        tools:ignore="ProtectedPermissions" />

as per below link :- How to grant MODIFY_PHONE_STATE permission for apps ran on Gingerbread

this permission is system permission not used by other application but i want to know is there any other way to achive this.

Thanks in Advance

MODIFY_PHONE_STATE is a system-only permission, you could root device and put your app in /system/priv-app folder.
