  15. @Override
  16. protected void onCreate(Bundle savedInstanceState) {
  17. super.onCreate(savedInstanceState);
  18. setContentView(R.layout.activity_main);
  19. textView = (TextView) findViewById(R.id.textView);
  21. TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
  23. String deviceId = telephonyManager.getDeviceId();
  24. String simSerialNumber = telephonyManager.getSimSerialNumber();
  25. String networkCountryIso = telephonyManager.getNetworkCountryIso();
  26. String simCountryIso = telephonyManager.getSimCountryIso();
  27. String deviceSoftwareVersion = telephonyManager.getDeviceSoftwareVersion();
  28. String voiceMailNumber = telephonyManager.getVoiceMailNumber();
  29. String simOperatorName = telephonyManager.getSimOperatorName();
  30. int networkType = telephonyManager.getNetworkType();
  33. if(telephonyManager.getPhoneType()==1)
  34. {
  35. setType="GSM";
  36. }
  37. textView.setText("deviceid:" + deviceId + "" + "\n simSerialNumber:" + simSerialNumber + "" + " \n networkCountryIso :" + networkCountryIso + "" + "\n simCountryIso :" + simCountryIso +
  38. "" + "\n deviceSoftwareVersion :" + deviceSoftwareVersion + "" + "\n voiceMailNumber :" + voiceMailNumber + "" + "\nNetworkType: " + networkType + "" + "\nsimOperatorName: " +
  39. simOperatorName+""+"\nphoneType:"+setType+""+"\nnetworkType:"+networkType);
  40. }
  41. @Override
  42. public boolean onCreateOptionsMenu(Menu menu) {
  43. // Inflate the menu; this adds items to the action bar if it is present.
  44. getMenuInflater().inflate(R.menu.main, menu);
