I am trying to implement sms scheduling app. I am calling a service after selecting the time when the user needs to schedule an sms. Everything works fine when the app is running in foreground and background. But not working when the app is closed. I have used alarm manager as well and same is the thing with alarm manager. I have also declared "Process" attribute in the manifest file. Any help would be appreciated.
These are my code files. Have a look.
1. MainActivity
public class MainActivity extends AppCompatActivity implements
View.OnClickListener{
Button mButton;
EditText mPhoneNumber;
EditText mMessage;
String message=null;
String phoneNumber=null;
Button alarmButton;
int number;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mButton = (Button)findViewById(R.id.send_button);
mPhoneNumber = (EditText) findViewById(R.id.phone_number);
mMessage = (EditText) findViewById(R.id.message);
message=mMessage.getText().toString();
phoneNumber=mPhoneNumber.getText().toString();
alarmButton=(Button)findViewById(R.id.alarm_button);
alarmButton.setOnClickListener(this);
mButton.setOnClickListener(this);
}
@Override
public void onClick(View view) {
switch(view.getId()){
case R.id.send_button:
if(!message.equals(null)&&!phoneNumber.equals(null)){
sendSS(mMessage.getText().toString(),mPhoneNumber.getText().toString());
}
break;
case R.id.alarm_button:
int currentHour,currentMinute;
Calendar ca = Calendar.getInstance();
currentHour = ca.get(Calendar.HOUR_OF_DAY);
currentMinute = ca.get(Calendar.MINUTE);
// Launch Time Picker Dialog
TimePickerDialog tpd = new TimePickerDialog(this,
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
sendPickedTime(hourOfDay,minute);
}
}, currentHour, currentMinute, true);
tpd.show();
break;
}
}
