How to make condition in android?

I have a Broadcast receiver in my app and get a url from server response from server response url I split package name and save in shared preference,now scenario is that when any app is added in device it will check that app package name from my saved package name if match then pass intent. problem is that when variable which I declared earlier was empty then how to match new package added with my saved packge.shows me null pointer exception.
here is code:-
public class CAppDownloadReceiver extends BroadcastReceiver {
String url, packageName, s_szDealCode;
CDealBuySharedPreference m_oSharedPreference;
/**
* Get Query String as Key-Value Pair.
*/
public static Map<String, String> getQueryMap(String query) {
Map<String, String> map = new HashMap<>();
String[] queryString = query.split("\\?");
if (queryString.length > 1) {
String[] params = queryString[1].split("&");
for (String param : params) {
String name = param.split("=")[0];
String value = param.split("=")[1];
map.put(name, value);
}
}
return map;
}
#Override
public void onReceive(Context context, Intent intent) {
m_oSharedPreference = new CDealBuySharedPreference(context);
HashMap<String, String> user = m_oSharedPreference.getDealUrlDetails();
try {
if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {
String installAppPackgeName = intent.getData().getSchemeSpecificPart();
url = user.get(CDealBuySharedPreference.s_szDealUrl);// getting mobile from saved preferences..........
packageName = getQueryMap(url).get("id");
System.out.println("Previous package stored :" + packageName);
System.out.println("new Package added" + installAppPackgeName);
if (installAppPackgeName.equals(packageName)) {
// If install app package name is same as url package name then do some task.
// Your app is installed now.
s_szDealCode = user.get(CDealBuySharedPreference.s_szDealCode);
System.out.println("Match...");
System.out.println("Broadcast url..." + url);
System.out.println("Broadcast deal code:-" + s_szDealCode);
} else {
System.out.println("does not match ");
}

How to implement instant messaging Application in android

I am working on an instant messaging android application . I have successfully implemented the chat between my application and web application .I have used compile 'io.socket:socket.io-client:0.6.2' library to implement this. But when i installed the same app on another mobile phone, device to device communication did not work. I think i am missing something here. What i have to implement in my app now. Broadcast Receiver or GCM(Google Cloud Messaging). My code is as below:
1. ChatActivity.java

AmazonSNS - AwsCredentials.properties - NullPointerException

I am new to Android Studio and intelliJ.
I am trying to work with AmazonSNS - Push. I am unable to figure out how to add AwsCredentials.properties file to classpath of the module. I get a NPE at line 57 in the image below(at method getResourceAsStream()). I added the required keys in AwsCredentials.properties file.
Error:
In the questions that i have come across on StackOverflow regarding similar issues, some suggested that the file should be in the root folder, where, src is. I placed it in the same folder as that of src, but still getting the NPE. I also tried placing the file in com/test/ but with no use.
How do i solve this? Are there any other steps involved?
EDIT after starting a bounty - Adding java files
Here is what i did till now..
Create an Android Application called MyApplication. Imported all classes(AndroidMobilePushApp.java, ExternalReceiver.java, MessageReceivingService.java) from the demo application. Added required libs, and ran it and got the registationId as response from Amazon.
In the same application, i created a new module called snspush and imported SNSMobilePush.java file into it. Also imported the AwsCredentials.properties file to the same path as that of SNSMobilePush.java. Added the keys in AwsCredentials.properties file.
Followed the steps in documentation to uncomment necessary funtions.

EDIT 2:
EDIT 3:
I changed the following code to:
AmazonSNS sns = new AmazonSNSClient(new PropertiesCredentials(
SNSMobilePush.class
.getResourceAsStream("AwsCredentials.properties")));
to
AmazonSNS sns = new AmazonSNSClient(new BasicAWSCredentials("ACCESS_KEY_REPLACED",
"SECRET_KEY_REPLACED"));
Now, there is a different error: Logcat

} catch (Exception e) {
LOGE(TAG, "AmazonPushClient", e);
}
}
#Nullable

return null;
}
}
private CognitoCachingCredentialsProvider cognitoCachingCredentialsProvider(Application application) {
return new CognitoCachingCredentialsProvider(
application,
IDENTITY_POOL_ID,

);
}
private AmazonSNSClient createPushClient(Application application) {

}
mNotifPreferencesHelper.saveNotificationPreferences(true);

platformEndpointRequest.setToken(token());
platformEndpointRequest.setPlatformApplicationArn(PLATFORM_APPLICATION_ARN);

}
}

}
NotifPreferencesHelper is just something to store the EndpointARN. You have to use this class in a background thread
In association you have to implements GcmListenerService etc.. SNS is just for subscribe, not receive.

With respect to the Properties Credentials
A. Are you sure you are exporting the file in the build? Have you made sure you can access the file using regular file I/O outside of the credentials provider? Are you sure the file is formatted correctly (see https://github.com/aws/aws-sdk-android/blob/master/aws-android-sdk-core/src/main/java/com/amazonaws/auth/PropertiesCredentials.java)
accessKey=KEY
secretKey=SECRET
Also looking at the source you should be able to load this file yourself using http://developer.android.com/reference/java/util/Properties.html.
However, I highly recommend not using this credentials provider. It is extremely unsafe in a mobile applications. Anyone could decompile your app and steal your credentials. A much safer approach is to use Amazon Cognito, which there is a plethora of examples. (Bottom of https://docs.aws.amazon.com/mobile/sdkforandroid/developerguide/setup.html , any of the examples here: https://docs.aws.amazon.com/mobile/sdkforandroid/developerguide/getting-started-android.html as well as samples in the GitHub repo https://github.com/awslabs/aws-sdk-android-samples
Cognito requires a little bit of set-up but the guides are tested, and it really doesn't take much more than a few minutes to be much more secure.

Don't think you should import 'SNSMobilePush' to a module of your android application
In the same application, i created a new module called snspush and
imported SNSMobilePush.java file into it. Also imported the
AwsCredentials.properties file to the same path as that of
SNSMobilePush.java. Added the keys in AwsCredentials.properties file.
SNSMobilePush is just a Java app provided by AWS to do tasks like
upload (bulkupload package) several tokens (device tokens or registration IDs) to Amazon SNS or
send a push notification.
You need to register your mobile app with AWS (using AndroidMobilePushApp android app). You should obtain below information (refer this link)
Client ID and client secret
API key
Device token or Registration ID (per device)
Then you can use SNSMobilePush java app or even a AWS SNS console as described here to send push notification to your registered device.
I would suggest you to try out sending push notification from the console instead of java app. You can register tokens from devices that will install your app in the future as described in the one of the options (preferably the last option) as described here

quickblox, how to retrieve custom parameters in chat?

i'm developing an android application using quickblox api. I'm using chat SMACK functionality (1 to 1 chat) and i try receive message from chat. I can retrieve the message text, but i can't get customs parameters.
Here is a screen about my message variable:
The values i need are values stored in 'map' : tempo, telefono, stato, nome , prefisso.. how i can retrieve that? I just try to search on quickblox documentation, but i have an api error when try to implement DefaultPacketExtension.
Thank you

Here is an example how to do it using QuickBlox Android SDK 1.1
To send message with additional parameters:
Map<String, Object> addinfoParams = new HashMap<String, Object>();
addinfoParams.put(Consts.AGE, 22);
addinfoParams.put(Consts.TYPE, "actor");
final String BODY = "Hey QuickBlox!";
Message message = createMsgWithAdditionalInfo(USER_ID, BODY, addinfoParams);
Log.i(TAG, "message: " + message.toXML());
try {
qbPrivateChat.sendMessage(USER_ID, message);
} catch (XMPPException e) {
e.printStackTrace();
}
...
private Message createMsgWithAdditionalInfo(int userId, String body, Map<?, ?> addinfoParams){
Message message = new Message(QBChatUtils.getChatLoginFull(userId), Message.Type.chat);
String addInfo = ToStringHelper.toString(addinfoParams, "", Consts.ESCAPED_AMPERSAND);
MessageExtension messageExtension = new MessageExtension(Consts.QB_INFO, "");
try {
messageExtension.setValue(Consts.ADDITIONAL_INFO, addInfo);
} catch (BaseServiceException e) {
e.printStackTrace();
}
message.addExtension(messageExtension);
message.setBody(body);
return message;
}
To receive message and get custom parameters:
chatMessageListener = new ChatMessageListener() {
#Override
public void processMessage(Message message) {
String from = message.getFrom();
String messageBody = message.getBody();
List<MessageExtension> messageExtensions = message.getExtensions();
}
#Override
public boolean accept(Message.Type type) {
switch (type) {
case normal:
case chat:
case groupchat:
return true;
default:
return false;
}
}
};

The Broadcast Receiver didn't start after starting the activity class

I am assigned a project on vehicle tracking system to be developed as an android app.
Project Brief:
A vehicle driver is been given a GPRS powered android OS installed phone so that the location is tracked. The assumption is that all route coordinates (latitude & longitude) are already stored in DB.Such that when the driver crosses a particular place, there should be an alert (change of status) in the DB.In this way, the tracking shall be made efficiently.
My Issue:
I have developed the program but unable to get it executed. I am wondering if my coding is totally wrong or I had left something in between. I have attached/pasted the program for your consideration.
I shall be too glad to receive inputs from you & see the dawn of the project's execution.
You shall reach me at inbasharu#gmail.com
Alternately, if you are magnanimous in helping me outright do buzz me # 9659709092/7305738685
