Telephonymanager is a service class that manages cell phone communication status and telephone network information, and this class provides a listen (Phonestatelistener listener,int events) method to monitor call status

Run the above program, you can see a phonelist file in the Ddms's File Explorer panel data/data/crazyit.monitorphone/files directory, the file will be imported to the computer can see the phone call information

Because I am testing with a real machine, I need root permission to export the file under DDMS, otherwise I can't open the folder

To get permission to open a folder in DDMS:

>ADB Shell

$ su

# chmod 755/data

# chmod 755/data/data

# chmod 755/data/data/crazyit.monitorphone/

# chmod 755/data/data/crazyit.monitorphone/files
