我有一个BroadcastListener检查传入的短信并处理它们以获得警报系统的潜在状态。

如果文本符合我的条件和前台应用程序的活动，我想在我的活动的 GUI 中显示状态。

为此，我尝试使用这样的意图：

public class SmsReader extends BroadcastReceiver implements Runnable
{
    private static final String LOG_TAG = "SMSReceiver";
    private String alarm = "15555215554";

    public static final String INCOMING_SMS_ACTION = "android.provider.Telephony.SMS_RECEIVED";
    public static final String ALARM_STATUS_ON_FULL = "moorehojer.alarmcontrol.intent.action.ALARM_STATUS_FULL_ON";
    public static final String ALARM_STATUS_ON_PART = "moorehojer.alarmcontrol.intent.action.ALARM_STATUS_PART_ON";
    public static final String ALARM_STATUS_OFF = "moorehojer.alarmcontrol.intent.action.ALARM_STATUS_OFF";

    @Override
    public void onReceive(Context _context, Intent intent) 
    {
        String intentActionToCall = "";

        if (intent.getAction().equals(INCOMING_SMS_ACTION)) 
        {
            //this stops notifications to others
            this.abortBroadcast();
            boolean releaseBroadcast = false;

            try
            {   
                Bundle myBundle = intent.getExtras();
                SmsMessage [] messages = null;

                if (myBundle != null)
                {
                    Object [] pdus = (Object[]) myBundle.get("pdus");
                    messages = new SmsMessage[pdus.length];

                    for (int i = 0; i < messages.length; i++)
                    {
                        messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);

                            if(!Util.UnifyPhoneNumberPrefix(messages[i].getOriginatingAddress()).equals(Util.UnifyPhoneNumberPrefix(this.alarm)))
                        {
                            releaseBroadcast = true;
                        }
                        else
                        {
                            if(messages[i].getMessageBody().substring(0, 5).equals("FS-C "))
                            {
                                boolean frakoblet01 = messages[i].getMessageBody().contains("FRAKOBLET1");
                                boolean frakoblet02 = messages[i].getMessageBody().contains("FRAKOBLET2");
                                boolean tilkoblet01 = messages[i].getMessageBody().contains("TILKOBLET1");
                                boolean tilkoblet02 = messages[i].getMessageBody().contains("TILKOBLET2");
                                boolean deltilkoblet01 = messages[i].getMessageBody().contains("DELTILKOBLET1");
                                boolean deltilkoblet02 = messages[i].getMessageBody().contains("DELTILKOBLET2");

                                if(deltilkoblet01 || deltilkoblet02)
                                {
                                    intentActionToCall = SmsReader.ALARM_STATUS_ON_PART;
                                }
                                else if(tilkoblet01 && tilkoblet02)
                                {
                                    intentActionToCall = SmsReader.ALARM_STATUS_ON_FULL;
                                }
                                else if(frakoblet01 && frakoblet02)
                                {
                                    intentActionToCall = SmsReader.ALARM_STATUS_OFF;
                                }
                                else
                                {
                                    releaseBroadcast = true;    
                                }
                            }
                        }
                    }
                }
            }
            catch(Exception e)
            {
                this.makeToast(_context, "Ex 1: "+e.toString());
            }
            /**/

            try 
            {
                if(releaseBroadcast)
                {
                    this.clearAbortBroadcast();
                }
            } 
            catch (Exception e) 
            {
                this.makeToast(_context, e.toString());
            }
        } 

        if(!intentActionToCall.equals(""))
        {
                Intent myIntent = new Intent(intentActionToCall);

                this.makeToast(_context, "Intent created:\n"+intentActionToCall);

                    this.makeToast(_context, "Trying broadcast");
                    myIntent.putExtra("message", "Hallelujah");
                    try
                    {
                        _context.sendBroadcast(myIntent);
                    }
                    catch(Exception e)
                    {
                        e.printStackTrace();
                    }
        }
    }

    private void makeToast(Context context, String message)
    {
        Toast.makeText(context, message, Toast.LENGTH_LONG).show();
    }

    public void run() {
        // TODO Auto-generated method stub

    }
}

但是每次代码到达该行时：

_context.sendBroadcast(myIntent);

操作系统出现一条消息，表明该进程已意外停止工作，并随着 try-catch 的介入而关闭。

我尝试删除该行并且代码运行到最后没有问题。
