从 SMS 中读取 otp 并设置为编辑文本 不工作

Question

在我的应用程序中，我试图从 SMS 中读取 otp，而无需在我的应用程序中输入内容。 但它不起作用我无法找出错误我试图纠正错误超过一周请帮助我找出错误在哪里，我创建了一个用于读取传入消息的类并将值传递给我的 OTPActivity 页面但是到达那里的空值

IncomingSms.java

public class IncomingSms extends BroadcastReceiver {

    // Get the object of SmsManager
    final SmsManager sms = SmsManager.getDefault();

    public void onReceive(Context context, Intent intent) {

        // Retrieves a map of extended data from the intent.
        final Bundle bundle = intent.getExtras();

        try {

            if (bundle != null) {

                final Object[] pdusObj = (Object[]) bundle.get("pdus");

                for (int i = 0; i < pdusObj.length; i++) {

                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();

                    String senderNum = phoneNumber;

                        String message = currentMessage.getDisplayMessageBody().replaceAll("\\D", "");

                        //message = message.substring(0, message.length()-1);
                        Log.i("SmsReceiver", "senderNum: " + senderNum + "; message: " + message);

                        Intent myIntent = new Intent("otp");
                        myIntent.putExtra("message", message);
                        myIntent.putExtra("number", senderNum);
                        LocalBroadcastManager.getInstance(context).sendBroadcast(myIntent);
                        // Show Alert


                }

            } // bundle is null

        } catch (Exception e) {
            Log.e("SmsReceiver", "Exception smsReceiver" + e);

        }
    }
}

OTP活动

 @Override
    public void onResume() {
        LocalBroadcastManager.getInstance(this).registerReceiver(receiver, new IntentFilter("otp"));
        super.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        LocalBroadcastManager.getInstance(this).unregisterReceiver(receiver);
    }

    private BroadcastReceiver receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent.getAction().equalsIgnoreCase("otp")) {
                final String message = intent.getStringExtra("message");
                // message is the fetching OTP
                Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();


                mPinEditText.setText(message);
 }
        }
    };

    //Initialization Varibles
    private void initViews() {
        if ((ActivityCompat.checkSelfPermission(OTPActivity.this, Manifest.permission.READ_SMS) != PackageManager.PERMISSION_GRANTED)) {
            ActivityCompat.requestPermissions(OTPActivity.this, new String[]{Manifest.permission.READ_SMS}, 100);
        } else {
            //Permission Granted
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case 100:
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    //Permission Granted
                } else {
                    //Permission Not Granted
                    Toast.makeText(getApplicationContext(), "Permission not granted", Toast.LENGTH_SHORT).show();
                }
        }
    }

日志显示此错误

Answer 1

您需要将android:permission="android.permission.BROADCAST_SMS" 添加到AndroidManifest.xml 中的接收器块中，这是接收短信所必需的。像这样的：

<receiver
    android:name=".IncomingSms"
    android:permission="android.permission.BROADCAST_SMS">
  <intent-filter>
    <action android:name="android.provider.Telephony.SMS_RECEIVED" />
  </intent-filter>
</receiver>

如果不想写receiver，可以使用简单的轻量级库https://github.com/VitaliBov/SmsInterceptor

你只需要重写接口方法，创建一个Interceptor类并与生命周期绑定即可。它看起来像这样：

public class AuthActivity extends AppCompatActivity implements OnMessageListener {
    private SmsInterceptor smsInterceptor;
    private EditText etAuthPassword;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_auth);
        initViews();
        initSmsInterceptor();
    }

    @Override
    protected void onResume() {
        super.onResume();
        smsInterceptor.register();
    }

    @Override
    protected void onPause() {
        super.onPause();
        smsInterceptor.unregister();
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        smsInterceptor.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }

    @Override
    public void messageReceived(String message) {
        // You can perform your validation here
        etAuthPassword.setText(message);
    }

    private void initViews() {
        etAuthPassword = findViewById(R.id.etAuthPassword);
        etAuthPassword.addTextChangedListener(new SmsTextWatcher() {
            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                if (charSequence.length() == 4) {
                    btnAuthPassword.setEnabled(true);
                    checkCode();
                } else {
                    btnAuthPassword.setEnabled(false);
                }
            }
        });
    }

    private void initSmsInterceptor() {
        smsInterceptor = new SmsInterceptor(this, this);
        // Not necessary
        smsInterceptor.setRegex(SMS_CODE_REGEX);
        smsInterceptor.setPhoneNumber(PHONE_NUMBER);
    }

    private void checkCode() {
        // Validation
        if (isValid) {
            navigateToMainScreen();
        }
    }
}
