how to change a static variable in broadcaster onReceive

how to change a static variable in broadcaster onReceive - android

I want to get the sending status of each phone number, so I define a variable statusMap to record the status, 0 means success, 1 means failed. And I assign value to statusMap at onReceive function, but after that the statusMap's value is still empty. how can I change a static value in onReceive function

manager.sendTextMessage(number, null, content, sentPI, null);
}
}

Remove this:
intent.putExtra("data2", statusMap);
setResult(RESULT_OK, intent);
//Log.i("msg", "statusMap length is" + statusMap.size());
// back to contacts
SendMessage.this.finish();
code from onClick and put it in onReceive:
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String n = numbers.poll();
switch (getResultCode()) {
case RESULT_OK:
Log.i("msg", "c:ok" + n);
statusMap.put(n, "0");
break;
default:
Log.i("msg", "c:failed" + n);
statusMap.put(n, "1");
break;
}
if(hashMap.size()==statusMap.size()){
intent.putExtra("data2", statusMap);
SendMessage.this.setResult(RESULT_OK, intent);
//Log.i("msg", "statusMap length is" + statusMap.size());
// back to contacts
SendMessage.this.finish();
}
}
The problem was that the onClick event is completed first that is you call set result and finish this activity and then onReceive is getting called so by the time your map is updated result was already sent

BroadCast Receiver makes slowly works to other services

when I listen push message from BroadcastReceiver I can take message but it makes slow other services for example I am sending "Message is taken" to my web service when I take push message but I can't send to my webservice it works very slowly when I listen to BroadcastReceiver for take message and when I delete BroadcastReceiver I can send message to my webservice very fastly

Problem is: The broadcast receiver that you are registering is implemented on the Main thread. The broadcast receiver handler is ALWAYS EXECUTED ON THE MAIN THREAD, thus, making your entire process slower. To implement receiver's own thread, you can explicitly do so by providing it's own Handler thread.
Register your broadcast receiver like this:
HandlerThread receiverHandlerThread = new HandlerThread("threadName");
receiverHandlerThread.start();
Looper looper = receiverHandlerThread.getLooper();
Handler handler = new Handler(looper);
context.registerReceiver(mHandleMessageReceiver,newIntentFilter(DISPLAY_MESSAGE_ACTION),null,handler);

Uploading xml file to server using Android Service

I am developing an application in android wrein I call a service that will upload a xml file to the server on click of a button.Problem is when I click the button first time it dosent get uploaded but when I click the button second time its gets uploaded...so let me know if there is any solution..pls help me.

onStartCommand intent:
This may be null if the service is being restarted after its process
has gone away, and it had previously returned anything except
START_STICKY_COMPATIBILITY.
http://developer.android.com/reference/android/app/Service.html
So try use:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
rather than finish();

onReceive Issue uses SMS

I am new to android programming and i encounter issue about the onReceive() method in Broadcast Receivers.I want to execute a specific method from the other class which is the MainActivity.java that has the method of TurnGPSOnOff(). It goes like this, every time system receive a SMS equal to the stored value in the shared preference the GPS will turn on if it is disabled and does vice versa.
MainActivity.java:
package com.smscontrol;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.provider.Settings;
import android.view.View;

import android.widget.Toast;
public class MainActivity extends Activity {
EditText editText1, editText2;
Button buttonSaveMem1;
#Override
/** Called when the activity is first created. */
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText1 = (EditText)findViewById(R.id.editText1);
editText2 = (EditText)findViewById(R.id.EditText01);
buttonSaveMem1 = (Button)findViewById(R.id.button1);
buttonSaveMem1.setOnClickListener(buttonSaveMem1OnClickListener);
LoadPreferences();
}
Button.OnClickListener buttonSaveMem1OnClickListener = new Button.OnClickListener(){
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
SavePreferences("loc_key", editText1.getText().toString());
SavePreferences("gps_key", editText2.getText().toString());
Toast.makeText(getBaseContext(), "Keywords Saved.", Toast.LENGTH_SHORT).show();
LoadPreferences();
}
};
private void SavePreferences(String key, String value){
Context context = getApplicationContext();
AppPrefs appPrefs = new AppPrefs(context);
appPrefs.setLoc_key(editText1.getText().toString());
appPrefs.setGPS_key(editText2.getText().toString());
}
private void LoadPreferences(){
Context context = getApplicationContext();
AppPrefs appPrefs = new AppPrefs(context);
String strSavedMem1 = appPrefs.getLoc_key();
String strSavedMem2 = appPrefs.getGPS_key();
editText1.setText(strSavedMem1);
editText2.setText(strSavedMem2);
}
public void turnGPSOnOff(){
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(!provider.contains("gps"))
{ //if gps is disabled

any advice or help will do. badly needed for the part of my thesis. thanks!

Start Activity inside onReceive BroadcastReceiver

str += "SMS from " + msgs[i].getOriginatingAddress();

trigger_message = msgs[i].getMessageBody().toString();

}

You have context passed as parameter to onRecieve() method, so just use:
#Override
public void onReceive(Context context, Intent intent) {
//start activity
Intent i = new Intent();
i.setClassName("com.test", "com.test.MainActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
It works, of course you have to change package and activity class name to your own.

I am using this and its work on my site:
Intent intentone = new Intent(context.getApplicationContext(), DialogAct.class);
intentone.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intentone);

Intent intent1 = new Intent();
intent1.setClassName(context.getPackageName(), MainActivity.class.getName());
intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent1);
to prevent those package exceptions
