在我的 android 代码中，我试图检测传入的 SMS 消息。下面的代码自 2 年以来一直在工作，但现在它停止工作了。我错过了哪些更新？
public class SmsListener extends BroadcastReceiver {
private String msgBody;
private SharedPreferences preferences;
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){
Toast.makeText(context,"message received",Toast.LENGTH_SHORT).show();
Bundle bundle = intent.getExtras(); //---get the SMS message passed in---
SmsMessage[] msgs = null;
String msg_from;
if (bundle != null){
//---retrieve the SMS message received---
try{
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for(int i=0; i<msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
msg_from = msgs[i].getOriginatingAddress();
msgBody = msgs[i].getMessageBody();
MainActivity.handleMessage(msgBody);
}
Toast.makeText(context,"message is:"+msgBody,Toast.LENGTH_SHORT).show();
}catch(Exception e){
Log.d("Exception caught",e.getMessage());
}
}
}
}
在我的主要活动中，我请求用户许可，并使用 SMS 接收器如下：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Updated///////////////////////////////////////////////////////////////////////////////////
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
requestSmsPermission();
else {
smsListener = new SmsListener();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(smsListener, intentFilter);
}
///////Updated///////////////////////////////////////////////////////////////////////////////////
}
private void requestSmsPermission() {
String permission = Manifest.permission.RECEIVE_SMS;
int grant = ContextCompat.checkSelfPermission(this, permission);
if ( grant != PackageManager.PERMISSION_GRANTED) {
String[] permission_list = new String[1];
permission_list[0] = permission;
ActivityCompat.requestPermissions(this, permission_list, 1);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 1) {
smsListener = new SmsListener();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(smsListener, intentFilter);
}
}

收到短信后，我的 android 应用程序没有检测到它，但它没有崩溃或显示任何内容。为什么？谢谢。
注意：我对使用验证码捕获短信不感兴趣。我希望我的应用程序能够捕获任何传入的短信。
