7. Convert the string into ascii code

8. Call the System Browser 9. determine the current mobile phone carrier

10. Determine the installation status of the application on the mobile phone

11. convert long type to byte array

 

1. Obtain the current mobile phone number

 

        = (TelephonyManager) =

 

 

 

2. check whether there is a network connection

 = (ConnectivityManager) = (info !=  &&                          

3. get request network data

 = = = client.execute(get);             

Obtain the signature information of a program.

=<PackageInfo> apps =<PackageInfo> iter === packageinfo.signatures[0, packageinfo.signatures[0 packageinfo.signatures[0 

The returned signature is a long string of data.

4. Get ctwap or ctnet?

      String CTWAP="ctwap"  String CTNET="ctnet"  Uri PREFERRED_APN_URI ="content://telephony/carriers/preferapn"= "nomatch"= context.getContentResolver().query(PREFERRED_APN_URI, , , = c.getString(c.getColumnIndex("apn"= =

5. Get the IMSI code of the mobile phone?

                TelephonyManager telManager="-----"+telManager.getSubscriberId());                 System.out.println("-----"+telManager.getSimSerialNumber());                 System.out.println("-----"+"-----"+"-----"+"-----"+telManager.getSimState());

6. determine the current network connection status?

              ="connectivity" (networkInfo !=  

7. convert a string to an Ascii code?

String toHexUtil (= "" 10: rt + = "A"; 11: rt + = "B"; 12: rt + = "C"; 13: rt + = "D"; 14: rt + = "E"; 15: rt + = "F "; + = String toHex (= (n/16 = 0 = toHex (n/16 nn = n % 16 = [] bs = (I = 0; I <bs. length; I ++ = "xyz" "The converted string is:" +

8. Call the System Browser

                         Intent intent= "android.intent.action.VIEW"=

9. determine the current mobile phone operator

TelephonyManager telManager ==( imsi! = (Imsi. startsWith ("46000") | imsi. startsWith ("46002" Toast. makeText (getApplicationContext (), "the current mobile number has been sent", 0 = (imsi. startsWith ("46001") {"the current Unicom number has been sent", 0 = (imsi. startsWith ("46003") {Toast. makeText (getApplicationContext (), "the current telecom number has been sent", 0 = Constants. sendNumber_JT ;}

10. determine the application installation status on the mobile phone

     <PackageInfo> pakageinfos ==  

11. Convert the long type into a byte array

* @*/      [] long2Bytes([] bytes =  [8 i = 8(= ()(l & 0xff--i] =>>= 8
