How to write unit tests for firebase notification?

How to write unit tests for firebase notification? - android

I have made the following class to receive firebase messages and create notifications. I have tested it by sending firebase messages to the app and it works perfectly. However, I need to write unit tests to test this feature. But the 2 unit tests I have written for it are failing.
onMessageReceived() receives data in a RemoteMessage object. It then finds the value of the key type and depending on whether it is 0 or 1, it calls either buildNotificationBigText() or buildNotificationBigPicture() . Hence I have written 2 test methods. In my test methods I have created a RemoteMessage object and passed this to onMessageReceived(). However, these tests are not working correctly and I get the following error:
java.lang.NullPointerException: Attempt to invoke virtual method 'void in.ac.bits_pilani.goa.ard.services.HandleFirebaseMessages.onMessageReceived(com.google.firebase.messaging.RemoteMessage)' on a null object reference

While testing it is advised to limit dependencies that you are testing. You could refactor your code in a way that it would not depend on FirebaseMessagingService.
For example instead of having your logic in onMessageReceived(), you could extract it to separate method preferably in other class (along with other methods from HandleFirebaseMessages) that would not depend on FirebaseMessagingService. It could even be structured so that it relies on plain java code, so that no instrumentation is required to run the test.
This way you would only be testing your code and not other dependencies, which would make it easier to test.

Android intent data return null

I am starter at Android and now I want to transfer data using intent from one activity to another.
First activity will collect datas and give it to second. but on second the data returns null. So have some errors on there. Here are my code.
public void previewStack(final Context context, final CreateStackNewActivity createStackNewActivity, final Stack stackDetails) {
Map<String, String> options = new HashMap<String, String>();
if(stackDetails.getStackId() != -1){
options.put("stack_id", String.valueOf(stackDetails.getStackId()));
}
int index = 1;
for(StackLineNew stackLine : stackDetails.getLines()){
options.put("title" + index, stackLine.getTitle());
options.put("line_type" + index, Integer.toString(stackLine.getLineType().intValue));
options.put("title" + index, stackLine.getTitle());
if (stackLine.getBody().indexOf("file:/") == -1 && stackLine.getBody().indexOf("content:") == -1) {
options.put("description" + index, stackLine.getBody());
if (stackLine.getLineId() != -1) {
options.put("line_id" + index, Integer.toString(stackLine.getLineId()));
}
}
index++;
}
Call<GenericAPIResponse> call = Hype4DAPI.previewStack(stackDetails.getName(), stackDetails.getCategory(), Integer.toString(stackDetails.getLines().size()), options, "");
call.enqueue(new Callback<GenericAPIResponse>() {
#Override
public void onResponse(Call<GenericAPIResponse> call, Response<GenericAPIResponse> response) {
if(response.isSuccessful()) {
GenericAPIResponse saveStackResponse = response.body();
System.out.println(saveStackResponse);
Toast.makeText(context, saveStackResponse.toString(), Toast.LENGTH_SHORT).show();
createStackNewActivity.saveInProgress = false;
createStackNewActivity.somethingHasChanged = false;
createStackNewActivity.updatePostButtonState();
Intent itnt = new Intent(createStackNewActivity, StackDetailsPage.class);
itnt.putExtra("stackId", stackDetails.getStackId());
itnt.putExtra("isPreview", "true");
itnt.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
createStackNewActivity.startActivity(itnt);
} else {
System.out.println(response.errorBody());
Toast.makeText(context, response.errorBody().toString(), Toast.LENGTH_SHORT).show();
}
}
#Override
public void onFailure(Call<GenericAPIResponse> call, Throwable t) {
t.printStackTrace();
}
});
}
And the code of second activity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_stack_details);
final Intent intent = getIntent();
final String stackId;
if (intent != null) { //Null Checking
stackId = intent.getStringExtra("stackId");
isPreview = intent.getStringExtra("isPreview");
stackTitleStr = intent.getStringExtra("stackTitle");
saveLine = (HashMap<String, Object>)intent.getSerializableExtra("saveLine");
}
else{
stackId = null;
}
On second activity, I have all variables are null. isPreview, stackTitleStr, saveLine are all null.
So anyone please help me quickly.

first you should not create the intent in the onResponse callBack method but create a static method in your StackDetailsPage activity that return the intent it needs. With that, this activity "said" to the other ones whats it needs, and it avoid duplicate string extra keys. use this :
//in StackDetailsPage activity
public static Intent getIntent(Context context, String stackId, String...)
{
Intent intent = new Intent(context, StackDetailsPage.class);
intent.putExtra("stackId", stackId);
...
return intent;
}
and then in onResponse method do that :
startActivity(StackDetailsPage.getIntent(context,stackDetails.getStackId(), ...))

FCM onReceived method to implement Shortcut Badger library

I found this library (https://github.com/leolin310148/ShortcutBadger) to implement app icon counter badge in android.
badge works when i implement in activity. but i want to implement this when push notification is received. i currently have the initialize code in onMesseageReceived() method in Firebase messaging service but its not working.
see code below:
Thanks for your help
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Logger.i("Received message");
//Shourtcut Badger
int badgeCount = 1;
ShortcutBadger.applyCount(context, badgeCount);
//parseNotification(bundle);
parseNotification(remoteMessage.getData());
if (remoteMessage.getData() != null) {
String str = remoteMessage.getData().get("notification");
String from_user = "";
String message = "";
String name = "";
int type = 0;
if (str != null && str.length() > 0) {
try {
JSONObject jobj = new JSONObject(str);
from_user = jobj.optString("from");
message = jobj.optString("message");
name = jobj.optString("name");
type = Integer.parseInt(jobj.optString("type"));
if (type == LIKE_STATUS) {
handleStatusLikeByFriendPush(jobj, "" + type);
} else if (type == PHOTO_UPDATE) {
handlePhotoUpdateByFriendPush(jobj, "" + type);
} catch (Exception e) {
e.printStackTrace();
}
} else {
message = "";//bundle.getString("message");
from_user = "";//bundle.getString("source");
if (from_user != null && from_user.contains(IMHandler.AT + IMHandler.DOMAIN)) {
from_user = from_user.substring(0, from_user.indexOf(IMHandler.AT));
}
showNotification(from_user, message, type, name);
}
}
}
public void handleStatusLikeByFriendPush(JSONObject jobj, String pushType) {
// method
}
public void handlePhotoLikeByFriendPush(JSONObject jobj, String pushType) {
//method implement
}
}
private void showNotification(String from, String body, int type, String name) {
}
}

After lots of research i understand implementation of this Shortcut badge is not working in FCM service. I Am Able to resolve this issue by simply calling a a custom service from FCM service each time push notification is received and the custom service handles the badge codes and there affter destroys itself.
This way is working perfectly.

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

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

Access browser url from running background service?

In Android is it possible for a background service to access the url of the web page a user is currently looking at in their Chrome browser? From what ive read so far this is not possible without root access. Im just asking to see if anyone knows if maybe there is some other standard way of doing it?

No, it is not possible if you're not a Chrome developer.

yes you can.
you can use accessibility service
note: if you're not an accessibility app, Google Play will not allow you on the app store if you use this API. If you're writing a personal app its fine.
example:

How to read text from an image using OCR in android

I want to implement OCR in Android. I.e. getting texts from a business card image. I used code from here.
But when I run this code I got the following error:
java.lang.NoClassDefFoundError:
org.apache.http.entity.mime.content.FileBody
I think it points to the following line:
final FileBody image = new FileBody(new File(filePath));
of the OCRServiceAPI class. How can I fix this?

Can't guess about your above error but I have done this task in Blackberry by using third party application ABBYY product of OCR on PHP server.
During my long R & D I have also worked on the below link of Github_Abbyy.
For using this code you should create a free account here: ocrsdk.com

Not all the Apache packages are available by default in Android, so you will have to download them from the Apache repositories and include those yourself. See the question Android libraries not found and the links provided in the answer there.
Edit: Specifically the sub-packages of org.apache.http.entity are not included, only the entity package itself.
In the example project given by the OCR API they have placed the mime package in a jar in the lib folder.

Checkout that whether you are getting correct path of the image which are selecting from the gallery.
I have also tried this demo and its working fine for me.
Here I'm posting my code:
