BroadCast Receiver makes slowly works to other services

BroadCast Receiver makes slowly works to other services - android

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);

unable to get the notification when the messsage arrives from gcm android

Example: In my application I have client,distributors and server.client ask questions to server and server will reply for that question via Gcm push notification.I have implemented this by googling it and push notification tutorials.
And my issue is, if I send a question from client,it gets displayed in server by parsing the link but I'm not getting the push notification. any one help me with this.I don't know where I have done mistake.

USB Serial communication between Android and computer

I need to create an App that receives and transmit text data from a computer to a Android App. I found this : https://github.com/mik3y/usb-serial-for-android.
I used the example to see if I starting like this I could see a comunication between then, when I used in my mobile it appears 1 device found Vendor 1519 Product 0020 No Driver. It's like not happened the communication and not found the computer.

Have you installed the driver your phone migh require to work? For example any Samsung smartphone will require the Key-software to be installed in order for the drivers to function properly. I am asuming you want to try USB-debugging, correct?

It seems that you don't have the right driver installed for your device.Try firstly to use google official tools for android development like adb and friends. If they don't work than you don't have the driver. Visit the site of the vendor of your mobile phone and download it.

It seems that you lack of USB driver.The driver should be download at http://www.ftdichip.com/Drivers/VCP.htm
according to you system version. The same problem confused me, and that driver solves this problem. Hope it works for you.

You're not reusing your list items. This is why the list is starting to "stutter".
There are a lot of answers on this problem that display the concept of reusing ListView items.
Like this one
In general: within your getView method, check if the convertView is null. If it is, inflate your view. If it's not null, just insert the items that you want to display. This should solve your stuttering list view problem.

Please use for existing layout in BaseAdpter as below
ViewHolder holder = null;
if ( convertView == null )
{
/* There is no view at this position, we create a new one.
In this case by inflating an xml layout */
convertView = mInflater.inflate(R.layout.listview_item, null);
holder = new ViewHolder();
holder.toggleOk = (ToggleButton) convertView.findViewById( R.id.togOk );
convertView.setTag (holder);
}
else
{
/* We recycle a View that already exists */
holder = (ViewHolder) convertView.getTag ();
}
this may helps you

i got following run time exception when click on my startwork button (changeworkstatus function called on click of startwork).
Can't create handler inside thread that has not called Looper.prepare()
so my question is how to solve above error ?

You are doing many things in other thread, then should be event thread, like toast displaying, dismissing dialog, please place your code which need to be in Event thread, in event thread by using either Handler, or Asynctask.
