Android. permission. MODIFY_PHONE_STATE permission

 

Android. permission. MODIFY_PHONE_STATE permission restriction has been changed to system permission

 

Normal applications can no longer be called

 

Therefore, all articles found on the internet that use android. permission. MODIFY_PHONE_STATE have expired.

 

However, there are still some reference methods.

 

Is to let your program Program System Program

 

One is premade to ROM.

 

Another method is to use the system signature.

 

First, I have passed the test, and the second is to be verified.

 

Also, just to save everyone some searching. I 've been researching this and here's what happened:

 

David marked the permission MODIFY_PHONE_STATE as signatureOrSystem. that means only apps installed to the/system folder or signed with the certificate used to build the phone (I. e. your phone's manufacturer) will be able to use the permission.

 

As a developer, if you are using the permission there is no work around... unless you can convince every manufacturer to include your app as a preinstalled bloatware.
