在使用Firebase身份验证时,我想要自动输入通过短信接收到的代码。我能够手动接收短信并完成身份验证过程,但是当我使用SmsRetriever时,应用程序会崩溃,然后底部对话框会出现。以下是Logcat中显示的所有内容:

以下是在我的Fragment中接收短信的代码:
private val SMS_CONSENT_REQUEST = 2 // Set to an unused request code
private val smsVerificationReceiver = object : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent) {
try {
if (SmsRetriever.SMS_RETRIEVED_ACTION == intent.action) {
val extras = intent.extras
val smsRetrieverStatus = extras?.get(SmsRetriever.EXTRA_STATUS) as Status
when (smsRetrieverStatus.statusCode) {
CommonStatusCodes.SUCCESS -> {
// Get consent intent
val consentIntent = extras.getParcelable<Intent>(SmsRetriever.EXTRA_CONSENT_INTENT)
try {
// Start activity to show consent dialog to user, activity must be started in
// 5 minutes, otherwise you'll receive another TIMEOUT intent
startActivityForResult(consentIntent, SMS_CONSENT_REQUEST)
} catch (e: ActivityNotFoundException) {
// Handle the exception ...
}
}
CommonStatusCodes.TIMEOUT -> {
// Time out occurred, handle the error.
}
}
}
} catch (e: Exception) {
Timber.e(e, "onReceive: ")
}
}
}
override fun onResume() {
super.onResume()
val task = SmsRetriever.getClient(requireActivity()).startSmsUserConsent(null)
val intentFilter = IntentFilter(SmsRetriever.SMS_RETRIEVED_ACTION)
requireActivity().registerReceiver(smsVerificationReceiver, intentFilter)
}
override fun onPause() {
super.onPause()
requireActivity().unregisterReceiver(smsVerificationReceiver)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
when (requestCode) {
// ...
SMS_CONSENT_REQUEST ->
// Obtain the phone number from the result
if (resultCode == Activity.RESULT_OK && data != null) {
// Get SMS message content
val message = data.getStringExtra(SmsRetriever.EXTRA_SMS_MESSAGE)
// Extract one-time code from the message and complete verification
// `message` contains the entire text of the SMS message, so you will need
// to parse the string.
message?.let { presenter.parseSms(it) }
// send one time code to the server
} else {
// Consent denied. User can type OTC manually.
}
}
}
有趣的是,进展顺利的情况很少,并且我不知道它取决于什么。此外,如果在 onReceive
中设置断点,则在调试模式下一切都会顺利进行。
