我正在使用Firebase电话身份验证,并在广播接收器的帮助下将顶部提取到应用程序中。下面我分享了OTPAutoReader代码,我正面临这个问题-

Caused by java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.Class.isInterface()' on a null object reference

以上问题是由本线引起的-

bundle.getParcelable(SmsRetriever.EXTRA_STATUS, Status::class.java)

下面的代码-

class OTPAutoReader : BroadcastReceiver() {

private var otpSmsListener: OTPSMSListener? = null

fun init(otpSmsListener: OTPSMSListener) {
    this.otpSmsListener = otpSmsListener
}

override fun onReceive(context: Context?, intent: Intent?) {
    if (SmsRetriever.SMS_RETRIEVED_ACTION == intent?.action) {
        val bundle: Bundle? = intent.extras
        if (bundle != null) {
            val status: Status? = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
                bundle.getParcelable(SmsRetriever.EXTRA_STATUS, Status::class.java)
            } else {
                bundle.getParcelable(SmsRetriever.EXTRA_STATUS)
            }
            if (status != null) {
                when (status.statusCode) {
                    CommonStatusCodes.SUCCESS -> {
                        val message: String? = bundle.getString(SmsRetriever.EXTRA_SMS_MESSAGE)
                        Log.i("TAG >> SUCCESS", message ?: "")
                        message?.let {
                            try {
                                val pattern = Pattern.compile("\\d{6}")
                                val matcher = pattern.matcher(message)
                                if (matcher.find()) {
                                    val otp = matcher.group(0)

                                    if (otp != null) {
                                        otpSmsListener?.onSuccess(otp)
                                    } else {
                                        otpSmsListener?.onFailure("OTP not receive")
                                    }
                                } else {
                                    otpSmsListener?.onFailure("OTP not receive")
                                }
                            } catch (e: Exception) {
                                e.printStackTrace()
                                otpSmsListener?.onFailure("Failed to retrieve SMS")
                            }
                        } ?: run {
                            otpSmsListener?.onFailure("Failed to retrieve SMS")
                        }
                    }

                    CommonStatusCodes.TIMEOUT -> {
                        Log.i("TAG >> TIMEOUT", "timeout")
                        otpSmsListener?.onFailure("timeout")
                    }
                }
            }
        }
    }
}

interface OTPSMSListener {
    fun onSuccess(otp: String)
    fun onFailure(msg: String)
}
}

注意:此问题仅在Android 13上出现。

u4vypkhs1#

这看起来类似于this question,其中的解决方案是使用来自androidx.core:core-ktx:1.10.0BundleCompat.getParcelable(Bundle, String, Class)而不是getParcelable(String, Class)
