在Android中我们可以通过下面这段代码获取SIM的iccid
TelephonyManager telephonyManager = (TelephonyManager)
getSystemService(TELEPHONY_SERVICE);
String simSerialNumber = telephonyManager.getSimSerialNumber();
很好,重点来了,如果我们此时需要获取带字母的ICCID,就会发现获取的并不全,在带字母的前一位就停止获取了,我就不去阐述原因了,百度一大把,今天我们介绍怎么正确获取所有的20位卡号:
1.第一步:连接你所使用的机器,打开电脑adb,输入命令adb shell getprop,就会获取机器的一连串信息:
此时我们只关注iccid,此时我的机器的iccid的标志位是: ril.yuga.iccid(不同的机器可能有不同的标志位,注意仔细查看)
2.第二步,在代码中使用标志位ril.yuga.iccid获取到物联网卡的iccid
看到这,应该有人能看懂我的操作,没错,我使用的是su命令,我再贴一下代码:
CommandUtil
package com.example.test.utils
import android.util.Log
import java.io.BufferedReader
import java.io.DataOutputStream
import java.io.IOException
import java.io.InputStreamReader
class CommandUtil {
companion object {
var TAG = "CommandUtil"
fun execRootCmdSilent(cmd: String?, onEnd: ((str: String) -> Unit)? = null) {
var process: Process? = null
var os: DataOutputStream? = null
var successResult: BufferedReader? = null
var errorResult: BufferedReader? = null
var successMsg: StringBuilder? = null
var errorMsg: StringBuilder? = null
val commandResult =
ShellUtils.CommandResult(1)
try {
process = Runtime.getRuntime().exec("su")
os = DataOutputStream(process.outputStream)
os.writeBytes(cmd)
os.writeBytes("exitn")
os.flush()
os.close()
commandResult.result = process.waitFor()
successMsg = StringBuilder()
errorMsg = StringBuilder()
successResult =
BufferedReader(InputStreamReader(process.inputStream))
errorResult =
BufferedReader(InputStreamReader(process.errorStream))
var s: String?
while (successResult.readLine().also { s = it } != null) successMsg.append(s)
while (errorResult.readLine().also { s = it } != null) errorMsg.append(s)
commandResult.successMsg = successMsg.toString()
commandResult.errorMsg = errorMsg.toString()
Log.e(
TAG,
commandResult.result.toString() + " | " + commandResult.successMsg + " | " + commandResult.errorMsg
)
if (commandResult.result == 0) {
//获取成功
onEnd!!.invoke(commandResult.successMsg)
} else {
onEnd!!.invoke("iccid卡获取异常")
}
} catch (e: Exception) {
val errmsg = e.message
if (errmsg != null) {
Log.i(TAG, errmsg)
onEnd!!.invoke("errmsg$errmsg")
}
} finally {
try {
os?.close()
successResult?.close()
errorResult?.close()
} catch (e: IOException) {
val errmsg = e.message
if (errmsg != null) {
Log.v(TAG, errmsg)
} else {
e.printStackTrace()
}
}
process?.destroy()
}
}
}
}
