Android programming to get the mobile phone model, local phone number, SDK version and firmware version (that is, the system version number)

In the android development platform, you can use telephonymanager to obtain local information.

Telephonymanager phonemgr = (telephonymanager) This. getsystemservice (context. telephony_service );
Txtphonemodel. settext (build. model); // Mobile Phone Model
Txtphonenumber. settext (phonemgr. getline1number (); // local phone number
Txtsdkversion. settext (build. version. SDK); // SDK version
Txtosversion. settext (build. version. Release); // firmware/OS version

Note:
According to Android's security mechanism, when using telephonymanager, you must add <uses-Permission Android: Name = "read_phone_state"/> to androidmanifest. xml. Otherwise, you cannot obtain the system license.
