I can get data from the database but why does it still show that there is no value for the image?
I have checked that the url is right to get the photo. The following things are the error showed in the logcat. Please give me some helps. Thank you.

You get wrong JSONObject , try this
try {
JSONObject objId = response.getJSONObject(0);
JSONObject objImage = response.getJSONObject(1);
Patient patient = new Patient();
patient.setTitle(objId.getString("id"));
patient.setThumbnailUrl(objImage.getString("image"));
patientList.add(patient);
} catch (JSONException e) {
e.printStackTrace();
}

Look at your response and try this
JSONObject obj = response.getJSONObject(0);
JSONObject obj1 = response.getJSONObject(1);
Patient patient = new Patient();
patient.setTitle(obj.getString("id"));
patient.setThumbnailUrl(obj1.getString("image"));

Firebase notification not sending from Java code

I can successfully send notifications from the Firebase console to my device, but when I try to do it from Java code, I get a very unhelpful error:
04-12 20:18:09.284 17549-17549/com.package.example W/System.err: at com.package.example.FCMNotification.pushFCMNotification(FCMNotification.java:102)
Here is my FCMNotification Class
public class FCMNotification {
public final static String AUTH_KEY_FCM = "FCM_SERVERKEY";
public final static String API_URL_FCM = "https://fcm.googleapis.com/fcm/send";
public static void pushFCMNotification(String deviceToken, String title, String body)
throws IOException, JSONException {
String authKey = AUTH_KEY_FCM; // You FCM AUTH key
String FMCurl = API_URL_FCM;
URL url = new URL(FMCurl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setUseCaches(false);
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Authorization","key="+authKey);
conn.setRequestProperty("Content-Type","application/json");
JSONObject json = new JSONObject();
json.put("to",deviceToken.trim());
JSONObject info = new JSONObject();
info.put("title", title); // Notification title
info.put("body", body); // Notification body
json.put("notification", info);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(json.toString());
wr.flush();
conn.getInputStream();
}
}
And I call this class in my activity like this
FCMNotification obj = new FCMNotification();
obj.pushFCMNotification("DEVICE_TOKEN", "TITLE", "BODY");
EDIT
My app might be having trouble connecting to firebase server itself, so I have included my manifest and Gradle:

Microsoft Translator API- why is Translate.execute returning nothing?

I am running an app to test whether I can use Microsoft Translator API on a phone running Android API 19. However, when I press a button to get translated text, instead of translating the text "This is my dog" to French, Microsoft Translator API returns "".
UPDATE: Logcat is returning this:

Is the error because of my code or is it because of Microsoft Translator API itself? (I am using microsoft-translator-java-api-0.6.2-jar-with-dependencies.jar from https://code.google.com/archive/p/microsoft-translator-java-api/downloads.)
UPDATE 2: I got the answer from Permission denied (missing INTERNET permission?): But permission is given. Apparently I was supposed to put the <uses-permission> tags above application.

why you need two doInBackground call? Remove one and try

NullPointerException while storing value of spinner in a string array [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 6 years ago.
I am trying to create a fill in the blanks game. I have given the options to choose from in a spinner dropdown (10 spinner for 10 blanks). Till now its working. But to calculate score, I want to store the selected options in a string array. Here I am getting a NullPointerException.

there is :
at com.example.harimohan.myapplication.StartPage.onItemSelected(StartPage.java:174)
in line 174 you have choose and null value
maybe you should initilize blank1 in on create method .

You can try to check the where the null is in line 174 (the blank1.getSelectedItem() return the null value). It's helpful for you to solve the problem . Please forgive my English is poor.
