I am creating an app for Phillips Hue Lights and I want to be able to click a button, which will do the post request from my app to a specific URL of the Hue Bridge to get a username returned.
My Code:
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import org.json.JSONObject;
import java.util.HashMap;
import java.util.concurrent.ExecutionException;
public class Device extends AppCompatActivity {
HashMap<String, String> params = new HashMap<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_device);
{
params.put("devicetype", "final_year_project#michelle");
PostHandler handler = new PostHandler(params);
try {
JSONObject response = handler.execute("http://192.168.1.85/api/").get();
Log.d("TEST_RESPONSE", response.toString());
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
}
}
}
I have also created my PostHandler class:
import android.os.AsyncTask;
import org.json.JSONObject;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.TimeUnit;
import okhttp3.FormBody;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;
public class PostHandler extends AsyncTask<String, Void, JSONObject> {
OkHttpClient client = new OkHttpClient();
HashMap<String, String> params = new HashMap<>();
public PostHandler(HashMap params) {
this.params = params;
}
public PostHandler() {
}
#Override
protected JSONObject doInBackground(String... url) {
client = new OkHttpClient.Builder()
.connectTimeout(5, TimeUnit.MINUTES)
.writeTimeout(5, TimeUnit.MINUTES)
.readTimeout(5, TimeUnit.MINUTES)
.build();
FormBody.Builder body = new FormBody.Builder();
for ( Map.Entry<String, String> entry : params.entrySet() ) {
body.add( entry.getKey(), entry.getValue() );
}
RequestBody formBody = body.build();
Request request = new Request.Builder()
.url(url[0])
.post(formBody)
.build();
try{
Response response = client.newCall(request).execute();
String result = response.body().string();
JSONObject json = new JSONObject(result);
return json;
}catch (Exception e){
e.printStackTrace();
}
return null;
}
}
I am getting an error "cannot resolve symbol params" and the post request does not work.
Does anyone know where I am going wrong? I am new to working with API's.
Add the following line after setContentView(R.layout.activity_device);:
ContentValues params = new ContentValues();
You have not declared the variable params anywhere in your code.

I'm using msl4j to interact with microsoft products, e.g. emails, calendars. When I call the user informations (without parameters) this will works fine. But, when I try to read messages from the inbox, the call ended with error 404 ("code":"ResourceNotFound","message":"Resource could not be discovered."). I don't know why. The API Permissions seems correct.

I try to make a second request in the HttpAsyncClient callback. But the second request is on wait state.
Example code:
package com.example.http;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.concurrent.FutureCallback;
import org.apache.http.impl.nio.client.CloseableHttpAsyncClient;
import org.apache.http.impl.nio.client.HttpAsyncClients;
import org.apache.http.util.EntityUtils;
import java.util.concurrent.Future;
public class AsyncClientHttpExample {
public static void main(String[] args) {
CloseableHttpAsyncClient httpClient = HttpAsyncClients.createDefault();
httpClient.start();
final HttpGet request1 = new HttpGet("http://httpbin.org/ip");
httpClient.execute(request1, new FutureCallback<HttpResponse>() {
#Override
public void completed(HttpResponse result) {
try {
System.out.println(EntityUtils.toString(result.getEntity()));
final HttpGet anotherRequest = new HttpGet("http://httpbin.org/headers");
Future<HttpResponse> future1 = httpClient.execute(anotherRequest, null);
HttpResponse anotherResponse = future1.get(); //the code get hand up here.
System.out.println("response 1 " + anotherResponse);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
#Override
public void failed(Exception ex) {
System.out.println(ex);
}
#Override
public void cancelled() {
}
});
}
}
I don't quite understand why the second request got hand up in the anotherResponse. I thought the second request is waiting for some lock that has already captured by request 1. But I haven't figure that out.
Hi i have created a handler in java for getting the events from dynamo DB
Here is my code
package com.Lambda.dynamodb;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.LambdaLogger;
import com.amazonaws.services.lambda.runtime.RequestHandler;
import com.amazonaws.services.lambda.runtime.events.DynamodbEvent;

System.out.println(record.getEventName());
System.out.println(record.getDynamodb().toString());
}
return "Successfully processed " + ddbEvent.getRecords().size() + " records.";
}
}
Lambda function able to write the events in cloudwatch but the challenge is i have to index all the streamed records to the AWS elasticsearch service endpoint and index it.
while search through blogs i got few code samples in python and node.js but my requirement is i have to build this lambda function in java
Could anyone please suggest how to achieve this in java lambda function?

I face a problem to get Json data into my application. On get action. I have solve the problem for POST. We have a ssl certificate but seems for get and post the way is little different. I can't figure out. So if people can give me an help here. I will appreciate.

From the compilation i get an error :
enter image description here
The error indicates that you are calling your get request without passing a HashMap.
My suggestion would be to either pass an empty HashMap if you have some URLs that require a body. Else remove it entirely:
public static String Ok_Get(Context context,String url) {
String data = "";
OkHttpClient okHttpClient= MyApp.handleSSLHandshake();
FormBody.Builder builder = new FormBody.Builder();
builder.build();
Request request = new Request.Builder().url(url).build();
If you still need it, when you call it make sure you include the HashMap:
Ok_Get(context, "your/url/string/here", Collections.<String, String>emptyMap())
I have made a java class to handle HTTP post requests and it sends back the result in string form. For some reason when I send the request I can print the response to the log but when return the string of the response to update the UI in the method my app crashes. Could any one explain whats happening here? I am trying to get better at java so pointing out any other bad practices would be appreciated .

Your code works, mostly, up to this point
D/OKHTTP3: Request body created
D/OKHTTP3: Request body created 2
D/OKHTTP3: Got Response
I remember reading, you can only receive the body string once
// Log.d("OKHTTP3",response.body().string());
String Fresponse = response.body().string();
// log Fresponse here
And close the resources in a finally block after the catch
More importantly you are using Okhttp. You don't need Asynctasks! Use the enqueue method instead of execute on the client call object
client.newCall(newReq).enqueue(new Callback() {
// handle response here
});
And you're processing JSON, so Retrofit would help you implement what you're already trying to do
The problem is you can call string() once. But I don't know why
