I had a problem with Pusher with Service application on Android.
When I using pusher on Application or Activity then It's working.
But I move it to Service and register with application in manifress like:
<service android:name=".services.PusherServices"/>
It's not working.
When i startService Pusher connected success with authorization, but It's not bind events when I call method for register Channel.

So i want to implement application which reads data from json format files. And I have created customer object for the data in json. And I want to send these object through kafka topic. So far i have successfully send String message to producer to consumer. But when i try to send object, in the consumer side, when I do .value().toString(). I got null value. The following is the code I have used:
This is producer:
public class MyProducer {
public static void main(String[] args) throws Exception {
Properties properties = new Properties();
properties.put("bootstrap.servers", "kafka.kafka-cluster-shared.non-prod-5-az-scus.prod.us.walmart.net:9092");
properties.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
properties.put("value.serializer", "xxxxxxxxx.KafkaJsonSerializer");
properties.put("acks", "1");
properties.put("retries", "2");
properties.put("batch.size", "16384");
properties.put("linger.ms", "1");
properties.put("buffer.memory", "33554432");
KafkaProducer<String, pharmacyData> kafkaProducer = new KafkaProducer<String, pharmacyData>(
properties);
String topic = "insights";
//try {
Gson gson = new Gson();
Reader reader = Files.newBufferedReader(Paths.get("......./part.json"));
List<pharmacyData> pdata = new Gson().fromJson(reader, new TypeToken<List<pharmacyData>>() {}.getType());
//pdata.forEach(System.out::println);
reader.close();
//} catch (Exception e) {
//e.printStackTrace();
//}
for (pharmacyData data : pdata) {
kafkaProducer.send(new ProducerRecord<String, pharmacyData>(topic, data), new Callback() {
#Override
public void onCompletion(RecordMetadata recordMetadata, Exception e) {
if (e == null) {
System.out.println(recordMetadata.partition() + "--" + recordMetadata.serializedValueSize());
} else {
e.printStackTrace();
}
}
});
}
kafkaProducer.close();
}
}
This is the customer object class:
public class pharmacyData {
private String load_date;
private String store_nbr;
private String state;
private String pmp_flag;
private String zero_flag;
private String submit_ts;
public pharmacyData(String load_date, String store_nbr, String state, String pmp_flag, String zero_flag, String submit_ts) {
this.load_date = load_date;
this.store_nbr = store_nbr;
this.state = state;
this.pmp_flag = pmp_flag;
this.zero_flag = zero_flag;
this.submit_ts = submit_ts;
}
public String getLoad_date() {
return load_date;
}
public void setLoad_date(String load_date) {
this.load_date = load_date;
}
public String getStore_nbr() {
return store_nbr;
}
public void setStore_nbr(String store_nbr) {
this.store_nbr = store_nbr;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
public String getPmp_flag() {
return pmp_flag;
}
public void setPmp_flag(String pmp_flag) {
this.pmp_flag = pmp_flag;
}
public String getZero_flag() {
return zero_flag;
}
public void setZero_flag(String zero_flag) {
this.zero_flag = zero_flag;
}
public String getSubmit_ts() {
return submit_ts;
}
public void setSubmit_ts(String submit_ts) {
this.submit_ts = submit_ts;
}
#Override
public String toString() {
return "pharmacyData{" +
"load_date='" + load_date + '\'' +
", store_nbr='" + store_nbr + '\'' +
", state='" + state + '\'' +
", pmp_flag='" + pmp_flag + '\'' +
", zero_flag='" + zero_flag + '\'' +
", submit_ts='" + submit_ts + '\'' +
'}';
}
}
this is the customer Serializer:
public class KafkaJsonSerializer implements Serializer {
private Logger logger = LogManager.getLogger(this.getClass());
#Override
public void configure(Map map, boolean b) {
}
#Override
public byte[] serialize(String s, Object o) {
byte[] retVal = null;
ObjectMapper objectMapper = new ObjectMapper();
try {
retVal = objectMapper.writeValueAsBytes(o);
} catch (Exception e) {
logger.error(e.getMessage());
}
return retVal;
}
#Override
public void close() {
}
}
This is the customer Deserializer:
public class KafkaJsonDeserializer implements Deserializer {
#Override
public void configure(Map map, boolean b) {
}
#Override
public Object deserialize(String s, byte[] bytes) {
ObjectMapper mapper = new ObjectMapper();
pharmacyData pdata = null;
try {
pdata = mapper.readValue(bytes, pharmacyData.class);
} catch (Exception e) {
e.printStackTrace();
}
return pdata;
}
#Override
public void close() {
}
}
This is consumer:
public class MyConsumer {
public static void main(String[] args) {
Properties properties = new Properties();
properties.put("bootstrap.servers", "kafka.kafka-cluster-shared.non-prod-5-az-scus.prod.us.walmart.net:9092");
properties.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
properties.put("value.deserializer", "xxxxxxxx.KafkaJsonDeserializer");
properties.put("group.id", "consumer-group-1");
properties.put("enable.auto.commit", "true");
properties.put("auto.commit.interval.ms", "1000");
properties.put("auto.offset.reset", "earliest");
properties.put("session.timeout.ms", "30000");
KafkaConsumer<String, pharmacyData> consumer = new KafkaConsumer<>(properties);
String topic = "insights";
consumer.subscribe(Collections.singletonList(topic));
while (true) {
ConsumerRecords<String, pharmacyData> consumerRecords = consumer.poll(100);
for (ConsumerRecord<String, pharmacyData> consumerRecord : consumerRecords) {
System.out.println(consumerRecord.key() + "--" + consumerRecord.toString());
//System.out.println(consumerRecord.offset() + "--" + consumerRecord.partition());
}
}
}
}
Can someone please help me with the issues? Thank you very much!
Problem solved:
The solution of this issue just add a default constructor as below:
public pharmacyData() {
}
See this page for more details.
I am using retrofit 2.3.0 to consume API's in my app but a week ago I started receiving error message and existing code was not able to display error message in UI.
Previously, I was using errorBody.toString() then suddenly after few months I got error and then last week I tried with errorBody.string() but it dodn't work. Now today it's working.
I have attached screenshots of response from server and my error handling also. Here is my code to display error message.
private static void showToastForError(retrofit2.Response<Object> response, int requestType) {
if (response != null && response.errorBody() != null) {
try {
JSONObject jObjError = null;
try {
jObjError = new JSONObject(response.errorBody() != null ? response.errorBody().toString() : "");
Toast.makeText(Application.getAppContext(), jObjError.getString("message"), Toast.LENGTH_LONG).show();
} catch (JSONException e) {
e.printStackTrace();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
I think you should custom call adapter to handle error.
Here my custom adapter
public final class ErrorHandlingAdapter {
/**
* A callback which offers granular callbacks for various conditions.
*/
public interface MyCallback<T> {
/**
* Called for [200, 300) responses.
*/
void success(Response<T> response);
/**
* Called for 401 responses.
*/
void unauthenticated(Response<?> response);
/**
* Called for [400, 500) responses, except 401.
*/
void clientError(Response<?> response);
/**
* Called for [500, 600) response.
*/
void serverError(Response<?> response);
/**
* Called for network errors while making the call.
*/
void networkError(IOException e);
/**
* Called for unexpected errors while making the call.
*/
void unexpectedError(Throwable t);
}
public interface MyCall<T> {
void cancel();
void enqueue(MyCallback<T> callback);
MyCall<T> clone();
boolean isExcute();
}
public static class ErrorHandlingCallAdapterFactory extends CallAdapter.Factory {
#Override
public CallAdapter<?> get(Type returnType, Annotation[] annotations,
Retrofit retrofit) {
if (getRawType(returnType) != MyCall.class) {
return null;
}
if (!(returnType instanceof ParameterizedType)) {
throw new IllegalStateException(
"MyCall must have generic type (e.g., MyCall<ResponseBody>)");
}
Type responseType = getParameterUpperBound(0, (ParameterizedType) returnType);
Executor callbackExecutor = retrofit.callbackExecutor();
return new ErrorHandlingCallAdapter<>(responseType, callbackExecutor);
}
private static final class ErrorHandlingCallAdapter<R> implements CallAdapter<R> {
private final Type responseType;
private final Executor callbackExecutor;
ErrorHandlingCallAdapter(Type responseType, Executor callbackExecutor) {
this.responseType = responseType;
this.callbackExecutor = callbackExecutor;
}
#Override
public Type responseType() {
return responseType;
}
#Override
public <R1> R adapt(Call<R1> call) {
return (R) new MyCallAdapter(call, callbackExecutor);
}
}
}
/**
* Adapts a {#link Call} to {#link MyCall}.
*/
static class MyCallAdapter<T> implements MyCall<T> {
private final Call<T> call;
private final Executor callbackExecutor;
MyCallAdapter(Call<T> call, Executor callbackExecutor) {
this.call = call;
this.callbackExecutor = callbackExecutor;
}
#Override
public void cancel() {
call.cancel();
}
#Override
public void enqueue(final MyCallback<T> callback) {
call.enqueue(new Callback<T>() {
#Override
public void onResponse(Call<T> call, Response<T> response) {
// on that executor by submitting a Runnable. This is left as an exercise for the reader.
callbackExecutor.execute(new Runnable() {
#Override
public void run() {
int code = response.code();
if (code >= 200 && code < 300) {
callback.success(response);
} else if (code == 401) {
if (Storage.getInstance().isLogin())
Storage.getInstance().logout(App.self().getApplicationContext());
} else if (code >= 400 && code < 500) {
callback.clientError(response);
} else if (code >= 500 && code < 600) {
callback.serverError(response);
} else {
callback.unexpectedError(new RuntimeException("Unexpected response " + response));
}
}
});
}
#Override
public void onFailure(Call<T> call, Throwable t) {
// on that executor by submitting a Runnable. This is left as an exercise for the reader.
callbackExecutor.execute(new Runnable() {
#Override
public void run() {
if (t instanceof IOException) {
if (call.isCanceled()) {
return;
}
callback.networkError((IOException) t);
Toast.makeText(App.self(), R.string.error_no_connect_internet, Toast.LENGTH_SHORT).show();
} else {
callback.unexpectedError(t);
}
}
});
}
});
}
#Override
public MyCall<T> clone() {
return new MyCallAdapter<>(call.clone(), callbackExecutor);
}
#Override
public boolean isExcute() {
return call.isExecuted();
}
}
}
Here my config to add custom call adapter
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(baseUrl)
.addCallAdapterFactory(new ErrorHandlingAdapter.ErrorHandlingCallAdapterFactory()) // custom call adapter
.addConverterFactory(GsonConverterFactory.create())
.client(getHeader())
.build();
And handle request, ex:
#GET("api/getSomething")
ErrorHandlingAdapter.MyCall<BaseResponse> getSomething(#Query("param"),...)
Handle response:
ErrorHandlingAdapter.MyCall<BaseResponse> mCalls = ApiUtils.getSomething(...);
mCalls.enqueue(new ErrorHandlingAdapter.MyCallback<BaseResponse>() {
#Override
public void success(Response<BaseResponse> response) {
//handle response
}
#Override
public void unauthenticated(Response<?> response) {
//handle unauthenticated error
}
#Override
public void clientError(Response<?> response) {
//handle clientError error
}
#Override
public void serverError(Response<?> response) {
//handle serverError error
}
#Override
public void networkError(IOException e) {
//handle networkError error
}
#Override
public void unexpectedError(Throwable t) {
//handle unexpectedError error
}
}
I added rerun test by Testng, but have a problem with duplicate tests in test report. Could you help me with this
private int retryCount = 0;
private int maxRetryCount = 1;
#Override
public boolean retry(ITestResult result) {
if (retryCount < maxRetryCount) {
System.out.println("Retrying test " + result.getName() + " with status "
+ getResultStatusName(result.getStatus()) + " for the " + (retryCount+1) + " time(s).");
retryCount++;
return true;
}
return false;
}
public String getResultStatusName(int status) {
String resultName = null;
if(status==1)
resultName = "SUCCESS";
if(status==2)
resultName = "FAILURE";
if(status==3)
resultName = "SKIP";
return resultName;
}
And
public class RetryListener implements IAnnotationTransformer {
#Override
public void transform(ITestAnnotation testannotation, Class testClass,
Constructor testConstructor, Method testMethod) {
IRetryAnalyzer retry = testannotation.getRetryAnalyzer();
if (retry == null) {
testannotation.setRetryAnalyzer(iOpiumListener.class);
}
}
}
But in test report displayed or two failed or one passed and one failed test
Olga, I believe that you're missing additional listener that will clean your test results:
public class TestListener implements ITestListener {
#Override
public void onTestStart(ITestResult result) {
}
#Override
public void onTestSuccess(ITestResult result) {
}
#Override
public void onTestFailure(ITestResult result) {
}
#Override
public void onTestSkipped(ITestResult result) {
}
#Override
public void onTestFailedButWithinSuccessPercentage(ITestResult result) {
}
#Override
public void onStart(ITestContext context) {
}
#Override
public void onFinish(ITestContext context) {
Set<ITestResult> failedTests = context.getFailedTests().getAllResults();
for (ITestResult temp : failedTests) {
ITestNGMethod method = temp.getMethod();
if (context.getFailedTests().getResults(method).size() > 1) {
failedTests.remove(temp);
} else {
if (context.getPassedTests().getResults(method).size() > 0) {
failedTests.remove(temp);
}
}
}
}
}
However, please, be aware of the fact that it'll work only with pure TestNG, case you have additional tools that rely on TestNG, i.e. Cucumber - It'll be necessary to clean those reports separately.
You can catch results which are incorrect (onTestFailure) and delete them when all the tests are done (onFinish)

and my AlarmReceiver class is
public class AlarmReceiver extends Activity {

setContentView(R.layout.alarmreceiver);
Button stopAlarm = (Button) findViewById(R.id.stopAlarm);
stopAlarm.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View arg0, MotionEvent arg1) {
stopService(new Intent(AlarmReceiver.this, CheckDestinationService.class));
mMediaPlayer.stop();
finish();
return false;
}
});
playSound(this, getAlarmUri());
}
private void playSound(Context context, Uri alert) {
mMediaPlayer = new MediaPlayer();
try {
mMediaPlayer.setDataSource(context, alert);
final AudioManager audioManager = (AudioManager) context
.getSystemService(Context.AUDIO_SERVICE);
if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) {
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
mMediaPlayer.prepare();
mMediaPlayer.start();
}
} catch (IOException e) {
System.out.println("OOPS");
}
}
//Get an alarm sound. Try for an alarm. If none set, try notification,
//Otherwise, ringtone.
private Uri getAlarmUri() {
Uri alert = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_ALARM);
if (alert == null) {
alert = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
if (alert == null) {
alert = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
}
}
return alert;
}
#Override
public void onBackPressed() {
//MainActivity.iMinDistance = 0;
stopService(new Intent(AlarmReceiver.this, CheckDestinationService.class));
mMediaPlayer.stop();
finish();
}
}
I tested AlarmReceiver class from other activites and it worked properly
but it not working from the service.
please help!!

I am just trying to create a simple MINA server and client to evaluate. Here is my code.
public class Server {
private static final int PORT = 8080;
static class ServerHandler extends IoHandlerAdapter {
#Override
public void exceptionCaught(IoSession session, Throwable cause) throws Exception {
cause.printStackTrace();
}
#Override
public void sessionCreated(IoSession session) {
System.out.println("session is created");
session.write("Thank you");
}
#Override
public void sessionClosed(IoSession session) throws Exception {
System.out.println("session is closed.");
}
#Override
public void messageReceived(IoSession session, Object message) {
System.out.println("message=" + message);
session.write("Reply="+message);
}
}
/**
* #param args
*/
public static void main(String[] args) throws Exception {
SocketAcceptor acceptor = new NioSocketAcceptor();
acceptor.getFilterChain().addLast( "logger", new LoggingFilter() );
acceptor.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "UTF-8" ))));
acceptor.setHandler(new Server.ServerHandler());
acceptor.getSessionConfig().setReadBufferSize( 2048 );
acceptor.getSessionConfig().setIdleTime( IdleStatus.BOTH_IDLE, 10 );
acceptor.bind(new InetSocketAddress(PORT));
System.out.println("Listening on port " + PORT);
for (;;) {
Thread.sleep(3000);
}
}
}
public class Client {
private static final int PORT = 8080;
private IoSession session;
private ClientHandler handler;
public Client() {
super();
}
public void initialize() throws Exception {
handler = new ClientHandler();
NioSocketConnector connector = new NioSocketConnector();
connector.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "UTF-8" ))));
connector.getFilterChain().addLast("logger", new LoggingFilter());
connector.setHandler(handler);
for (;;) {
try {
ConnectFuture future = connector.connect(new InetSocketAddress(PORT));
future.awaitUninterruptibly();
session = future.getSession();
break;
} catch (RuntimeIoException e) {
System.err.println("Failed to connect.");
e.printStackTrace();
Thread.sleep(5000);
}
}
if (session == null) {
throw new Exception("Unable to get session");
}
Sender sender = new Sender();
sender.start();
session.getCloseFuture().awaitUninterruptibly();
connector.dispose();
System.out.println("client is done.");
}
/**
* #param args
*/
public static void main(String[] args) throws Exception {
Client client = new Client();
client.initialize();
}
class Sender extends Thread {
#Override
public void run() {
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
handler.messageSent(session, "message");
}
}
class ClientHandler extends IoHandlerAdapter {
#Override
public void sessionOpened(IoSession session) {
}
#Override
public void messageSent(IoSession session, Object message) {
System.out.println("message sending=" + message);
session.write(message);
}
#Override
public void messageReceived(IoSession session, Object message) {
System.out.println("message receiving "+ message);
}
#Override
public void exceptionCaught(IoSession session, Throwable cause) {
cause.printStackTrace();
}
}
}
When I execute this code, the Client seems to keep sending a message instead of stopping after it sends. It looks to me that there is a recursive call in underlying MINA code. I know that I am doing something wrong.
Can somebody tell me how to fix this?
Thanks.
Try to initialize and start your sender and use the session within sessionOpened (ClientHandler)
