为什么不调用广播接收器的onreceive（）方法？

Question

I am a beginner in android development. I am trying to make a SMS scheduler app.My app's broadcast receiver's onReceive() method is not getting invoked? Given below is my source code.I have looked into some other links like Basic Android alarm app, Broadcast Receiver's onReceive() method not being called Please,I would like to know where I went wrong.Thanks in advance.

1. Homepage.java

     public class Homepage extends Activity { public EditText get_number; public EditText text_box; public String search_string,text_box_buffer; public Bundle bundle; public Intent mesg_intent; public PendingIntent pending_intent; public AlarmManager alarmManager; TimePickerFragment newFragment = new TimePickerFragment(); public void showTimePicker(View view) { newFragment.show(getFragmentManager(),"timepicker"); } public void messageSave(View view) { search_string=get_number.getText().toString(); text_box_buffer=text_box.getText().toString(); bundle.putCharSequence("number",search_string); bundle.putCharSequence("message", text_box_buffer); mesg_intent.putExtras(bundle); pending_intent = PendingIntent.getService(this,0,mesg_intent,0); alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP,newFragment.getTime(),pending_intent); Toast.makeText(this,"SMS scheduled to be sent",Toast.LENGTH_SHORT).show(); } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_homepage); get_number = (EditText) findViewById(R.id.contacts_search); text_box = (EditText) findViewById(R.id.text_box); bundle = new Bundle(); mesg_intent = new Intent(this,Alarmservice.class); } @Override public boolean onOptionsItemSelected(MenuItem item) { int id = item.getItemId(); if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } 

   }

2. TimepickerFragment.java

    public class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener 

   { public Calendar c = Calendar.getInstance(); public int hour = c.get(Calendar.HOUR_OF_DAY); public int minute = c.get(Calendar.MINUTE);

    @Override public Dialog onCreateDialog(Bundle savedInstanceState) { return new TimePickerDialog(getActivity(),this,hour,minute,DateFormat.is24HourFormat(getActivity())); } public void onTimeSet(TimePicker view, int hourOfDay, int minuteset) { hour=hourOfDay; minute=minuteset; } public long getTime() { long time_ret = new GregorianCalendar().getTimeInMillis()+((hour*60*60*1000)+(minute*60*1000)); return time_ret; } 

   }

3. Alarmservice.java

    public class Alarmservice extends BroadcastReceiver { @Override public void onReceive(Context context,Intent intent_local) { try { Bundle received_bundle = intent_local.getExtras(); String number = (String) received_bundle.getCharSequence("number"); String message = (String) received_bundle.getCharSequence("message"); SmsManager smsManager = SmsManager.getDefault(); smsManager.sendTextMessage(number, null, message, null, null); Toast.makeText(context,"SMS successfully sent",Toast.LENGTH_SHORT).show(); } catch (Exception e) { Toast.makeText(context,"SMS failed",Toast.LENGTH_SHORT).show(); } } 

   }

4. Manifest.xml

    <uses-sdk android:minSdkVersion="16" android:targetSdkVersion="24" /> <uses-permission android:name="android.permission.SEND_SMS"/> <uses-permission android:name="com.android.alarm.permission.SET_ALARM"/> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".Homepage" android:label="@string/app_name" android:screenOrientation="sensor" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:process=":remote" android:name=".Alarmservice"/> </application> 

Answer 1

The problem is with creating the intent, do it like this:

mesg_intent = new Intent(this, Alarmservice.class);
mest_intent.putExtras(bundle);
pending_intent = PendingIntent.getBroadcast(this, 0, mesg_intent, PendingIntent.FLAG_UPDATE_CURRENT);
