Synchronize Dialog Boxes

I have a broadcast receiver that on boot of the phone runs a pending intent. The pending intent opens a dialog box to alert the user.
I noticed that if there are several dialog boxes who's time has passed, they all fire off at once. Which leads to only the first dialog box displayed. When you click on the 'dismiss' button the it dismisses all the dialog boxes.
Is there a way to for each box to be displayed one at a time and not jam up like this?
I read up on using 'synchronize' but it seems to be only used in networking. Can you let me know what would be the best approach to resolving this issue?
My code:
package com.google.android.gcm.demo.app.Alerts;

afd.close();

if (vibrateState == 0) {
// Get instance of Vibrator from current Context
vibrate = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
// Start immediately
// Vibrate for 200 milliseconds
// Sleep for 500 milliseconds
long[] pattern = { 0, 200, 500 };
// The "0" means to repeat the pattern starting at the beginning
// CUIDADO: If you start at the wrong index (e.g., 1) then your
// pattern will be off --
// You will vibrate for your pause times and pause for your vibrate
// times !
vibrate.vibrate(pattern, 0);
} else {
}
}
}

In order to resolve this issue, I compared the current date to when the alert fired off. If the alert passed I, I put it in an arrary list. Then I used a intent to send the list to another activity. In that activity, I used a another for loop to process the dialog boxes one at a time.

using puelocesar / android-lib-magick

I am a beginner in Android. I want a sample app which uses this library: https://github.com/puelocesar/android-lib-magick. I tried to use https://github.com/lilac/Android-ImageMagick before - I made lots of changes to make it work but the result I got was not satisfactory.
I just want to know which class to call for a particular thing.
These are the effects i am getting using https://github.com/lilac/Android-ImageMagick
blur, charcoal and no effect looks exactly same. when i select edge it shows blur image.
and the noise effects appear but they look like red and green dots are drawn manually on that image.
below is the code which runs application.
it searches for images in sd card with hard coded name and extention. it gets all the ibages but i am unable to understand wha it does with those images because it shows only one image on screen.
also dont know test.txt is created. this code is present in library as AndroidMagickActivity
i did some changes in android.mk file after searching for long time and now its running but the output is not that good.
please anybody help me to improve results of lilac library or help me to understand how to use https://github.com/puelocesar/android-lib-magick
i am beginner and i don't know how to use NDK and how to create JNI and .so files

Getting force close error in android when using threading

In my application i want to do bluetooth chat. I'm facing a problem in threading. In my application my android phone will work as server which has a blocking statement
socket=mServerSocket.accept();
for this purpose i've created a child thread so that it will run separately. But before finishing this child thread main thread goes down giving Force Close and if i use the .join() method it hangs up my UI.
What is the solution to run both threads parallel?
this is my code
main Activity
package com.my.bluechat_2_1;

import android.bluetooth.BluetoothAdapter;

setContentView(R.layout.main);
chatWindow=(TextView)findViewById(R.id.textView1);
doStart();
}
private void doStart(){
Button btnStart=(Button)findViewById(R.id.button1);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// Get local Bluetooth adapter
btAdapter = BluetoothAdapter.getDefaultAdapter();
// If the adapter is null, then Bluetooth is not supported
if(btAdapter == null)
{
Toast.makeText(context, "Device does not support Bluetooth", Toast.LENGTH_LONG).show();
}
if (!btAdapter.isEnabled()) {
Intent discoverableIntent = new
Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);
startActivity(discoverableIntent);
}
chatWindow.append("Waiting for connection...\n");
btHandler=new BlueHandler(context,chatWindow,btAdapter);
Thread acceptThread=new Thread(btHandler);
acceptThread.start();
}
});
}
}

String s;
int bytes; // bytes returned from read()
// Keep listening to the InputStream until an exception occurs
while (true) {
try {
// Read from the InputStream
bytes=btInputStream.read(buffer);
s= new String(buffer);
// Send the obtained bytes to the UI Activity
textView.append("received ::" +s+"\n");
} catch (IOException e) {
break;
}
}
}
}

You're probably getting a crash because you're accessing a textView on the worker thread. You'll need to use TextView.post(Runnable) to make that not happen.
In reality you should be using a bindable Service to do this kind of work. You can post back to the UI via broadcast intents or callback methods, That way you don't have to worry about rotation bugs.

Are you performing a long operation in the constructor of your children thread? Each long operation must be done in the run() method.

Turn FTP command into ASync Task?

First off, don't flame me for not searching, I've looked for answers to this and while there are answers out there, I can't understand any of them.
Now, with that aside, I'm trying to put my ftp command into an ASync task for Android.
Code:
package com.dronnoc.ftp;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.io.CopyStreamEvent;
import org.apache.commons.net.io.CopyStreamListener;
import org.apache.commons.net.io.Util;
import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;
import android.widget.TextView;
public class Main extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
FTPTransfer ftp = new FTPTransfer("hostname", "user", "pass");
String data = Environment.getDataDirectory().toString();
data += "/data/com.dronnoc.ftp/databases/test.db";
boolean result = ftp.upload(data, "/ftp_dir/test.db");
if(result)
{
Log.d("message", "Upload Successful.");
}
else
{
Log.e("message", ftp.error());
}
ftp.close();
}
}
FTPTransfer.java

if(ftp.login(username, pass))
{
ftp.enterLocalPassiveMode();

}
}
catch (FTPConnectionClosedException e) { error = e.getMessage(); }
catch (SocketException e) { error = e.getMessage(); }
catch (IOException e) { error = e.getMessage(); }
}
public boolean upload(String localName, String remoteName)
{
if(ftp.isConnected() && connected)
{
try {

boolean result = ftp.storeFile(remoteName, file);
if(result) { return true; }
else { return false; }
}
catch (FileNotFoundException e) { error = e.getMessage(); return false; }
catch (IOException e) { error = e.getMessage(); return false; }
}
return false;
}
public boolean upload(File localName, String remoteName)
{

{
try {

boolean result = ftp.storeFile(remoteName, file);
if(result) { return true; }
else { return false; }
}
catch (FileNotFoundException e) { error = e.getMessage(); return false; }
catch (IOException e) { error = e.getMessage(); return false; }
}
return false;
}
public boolean download(String remote, String local)
{
//TODO Put appropriate code here
return false;
}
public boolean close()
{
try {
ftp.disconnect();
return true;
} catch (IOException e) {
error = e.getMessage();
return false;
}
}
public String error()
{
return error;
}
}
What I want to know is how I can put my FTP function into an ASync task so that I can run it in a background activity and update a progress bar, and also indicate how many bytes its uploaded so far?
Cheers
EDIT
The code itself works at the moment, I just need to know how to make it into an Async task

Not sure if you're asking how to use the AsyncTask but in case you are here's a tutorial about using AsyncTask to make requests to a web service. This can be extended easily to perform FTP in the background. AsyncTask can also support Progress though I don't think it's mentioned in the tutorial.
Basically your upload function needs to move to doInBackground and so does the connection code. See http://geekjamboree.wordpress.com/2011/11/22/asynctask-call-web-services-in-android/

Just giving you few hints , try to take help from this.

EditText editText1=(EditText)findViewById(R.id.emailText);
EditText editText2=(EditText)findViewById(R.id.passwordText);
login.setOnClickListener(new OnClickListener() {

if((editText1.getText()+" ").trim().equals("") || editText1.getText() == null || (editText2.getText()+" ").trim().equals("") || editText2.getText() == null ){
//show error message here
}
else{
//perrform your action here
//either start a new activity or do something else
}
}
});
Hope this will help you.

I have found the following tutorial which has definitely helped me implement the correct login and registration screens using these resources:
Material Design
Shared Preferences
PHP scripts
MySQL Database
SQLlite Database
This is the link to the tutorial.
I know this is extremely late but I hope it can help you.
