SMSを読み取るためのKotlinコード：
1-この権限をAndroidManifest.xmlに追加します。
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
2-BroadCastreceiverクラスを作成します。
package utils.broadcastreceivers
import android.content.BroadcastReceiver
import android.content.Context
import android.content.Intent
import android.telephony.SmsMessage
import android.util.Log
class MySMSBroadCastReceiver : BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent?) {
var body = ""
val bundle = intent?.extras
val pdusArr = bundle!!.get("pdus") as Array<Any>
var messages: Array<SmsMessage?> = arrayOfNulls(pdusArr.size)
// if SMSis Long and contain more than 1 Message we'll read all of them
for (i in pdusArr.indices) {
messages[i] = SmsMessage.createFromPdu(pdusArr[i] as ByteArray)
}
var MobileNumber: String? = messages[0]?.originatingAddress
Log.i(TAG, "MobileNumber =$MobileNumber")
val bodyText = StringBuilder()
for (i in messages.indices) {
bodyText.append(messages[i]?.messageBody)
}
body = bodyText.toString()
if (body.isNotEmpty()){
// Do something, save SMS in DB or variable , static object or ....
Log.i("Inside Receiver :" , "body =$body")
}
}
}
3-Android 6以降の場合は、SMS権限を取得します。
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M &&
ActivityCompat.checkSelfPermission(context!!,
Manifest.permission.RECEIVE_SMS
) != PackageManager.PERMISSION_GRANTED
) { // Needs permission
requestPermissions(arrayOf(Manifest.permission.RECEIVE_SMS),
PERMISSIONS_REQUEST_READ_SMS
)
} else { // Permission has already been granted
}
4-このリクエストコードをアクティビティまたはフラグメントに追加します。
companion object {
const val PERMISSIONS_REQUEST_READ_SMS = 100
}
5-許可チェック要求の結果のオーバーライドfun：
override fun onRequestPermissionsResult(
requestCode: Int, permissions: Array<out String>,
grantResults: IntArray
) {
when (requestCode) {
PERMISSIONS_REQUEST_READ_SMS -> {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Log.i("BroadCastReceiver", "PERMISSIONS_REQUEST_READ_SMS Granted")
} else {
// toast("Permission must be granted ")
}
}
}
}
