Cannot get the value from sharedPrefenced

Cannot get the value from sharedPrefenced - java

Hey guys again with my question
So as in the title, my apps need data from another activity using sharedPreferenced
So far so good I got the data I store WHEN I click the button but when i tried to get the data on the onCreate it just crashing with this error code:

As you can see I tried to automatically get the Highest bpm dan Lowest bpm but it spans the same error so I'm in a pickle now so if anyone can help with it dan fast I'll be grateful for that. And sorry for my English it's not my first language so I can't express it really well.

The TextView in your Information.Java are not assigned to anything within your onCreate method before you try calling the setText method. This is what the error is complaining about.
Your assignments are in the clear(View view) method for some reason.... they should be in the onCreate method.
i.e move
name = (TextView) findViewById(R.id.etName);
phonenum = (TextView) findViewById(R.id.etPhoneNum);
highest = (TextView) findViewById(R.id.etHighest);
lowest = (TextView) findViewById(R.id.etLowest);
out of the clear and get methods and into the onCreate method like:
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.information);
name = (TextView) findViewById(R.id.etName);
phonenum = (TextView) findViewById(R.id.etPhoneNum);
highest = (TextView) findViewById(R.id.etHighest);
lowest = (TextView) findViewById(R.id.etLowest);
sharedpreferences = getSharedPreferences(mypreference,
Context.MODE_PRIVATE);
if (sharedpreferences.contains(Name)) {
name.setText(sharedpreferences.getString(Name, ""));
}
if (sharedpreferences.contains(PhoneNum)) {
phonenum.setText(sharedpreferences.getString(PhoneNum, ""));
}
if (sharedpreferences.contains(Highest)) {
highest.setText(sharedpreferences.getString(Highest, ""));
}
if (sharedpreferences.contains(Lowest)) {
lowest.setText(sharedpreferences.getString(Lowest, ""));
}
}

Your issue actually brings up a larger issue that is especially relevant when developing a mobile app: Locale. Rather than use Double.parse(), which does not take Locale into account, consider using NumberFormat instead.
NumberFormat nf = NumberFormat.getInstance(); //gets an instance with the default Locale
Number parsed = nf.parse(percentageView.getText().toString());
beanEachQuetionScore.quetionScore = parsed.doubleValue();
For your float values, you can use the same concept:
Number parsedFloat = nf.parse(someFloatString);
float floatVal = parsedFloat.floatValue();
This of course assumes that OP is in a Locale that uses ',' instead of '.' as a separator.

error return NULL app json_code return NULL

I have a android application news, where I receive data from a server Jons until everything well, the problem is that when I'm in the app and minimize to do something else and when I try to resume where I left off the app comes with NULL data

How do I not return NULL
Thank you

In AsyncTask, stop making registerReceiver() freeze the app

Since I finally figured out that the registerReceiver() method is usually running on the UI-Thread, I now want to change that. I just need some advice of how I could do that.
How would I be able to change registerReceiver() to stop freezing my app?
My doInBackground() method from the AsyncTask, runs another method that is using the registerReceiver(mReceiver, filter) method (both variables are already defined). But I want to keep seeing my ProgressDialog instead of making the app freezing.
I read about using a Handler and a new Thread, but I need some help there.
Thanks in advance.

Move it to onProgressUpdate() method, or better , onPostExecute()/onPreExecuteMethod() depending on your need.
These methods run on UI thread and not on the new thread creetaed by the Asynctask

Can not access SharedPreferences value in another class after restart

I am using csipsimple code and customised it to show brandname by getting json value from webservice . I am using SharedPreferences to store value .
Once the application is force closed , or device restart SharedPreferences are lost . I am using commit and clear but still the values are null .
BasePrefsWizard is the class responsible for pulling web data and DialerFragment is the other class i am calling the BrandName ( it is SavedBrand/ brand in code)

You should not clear the SharedPreferences in the onDestroy() method, because when you run your activity or your application again, all the saved values and variables in preferences are deleted, ( like you installed your application for the first time).
PS : here is a tutorial about Using SharedPreferences and Storing Data in Android

You are clearing your preferences in your code,
#Override
protected void onDestroy() {
//byMe
super.onDestroy();
//Preferences cleared
getSharedPreferences(WIZARD_PREF_NAME, MODE_PRIVATE).edit().clear().commit();
saveArray(webArray);
}
This is clearing your preferences.

You are clearing the shared prefereence in onDestroy:
#Override
protected void onDestroy() {
//byMe
super.onDestroy();
getSharedPreferences(WIZARD_PREF_NAME, MODE_PRIVATE).edit().clear().commit(); // <-- Remove this
saveArray(webArray);
}

You delete it in:
#Override
protected void onDestroy() {
super.onDestroy();
getSharedPreferences(WIZARD_PREF_NAME, MODE_PRIVATE).edit().clear().commit();
saveArray(webArray);
}

Here is an code snippet , hoping it will help you.
1)An function which carries the http get service
private String SendDataFromAndroidDevice() {
String result = "";
try {
HttpClient httpclient = new DefaultHttpClient();
HttpGet getMethod = new HttpGet("your url + data appended");
BufferedReader in = null;
BasicHttpResponse httpResponse = (BasicHttpResponse) httpclient
.execute(getMethod);
in = new BufferedReader(new InputStreamReader(httpResponse
.getEntity().getContent()));
StringBuffer sb = new StringBuffer("");
String line = "";
while ((line = in.readLine()) != null) {
sb.append(line);
}
in.close();
result = sb.toString();
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
2) An Class which extends AsyncTask
private class HTTPdemo extends
AsyncTask<String, Void, String> {
#Override
protected void onPreExecute() {}
#Override
protected String doInBackground(String... params) {
String result = SendDataFromAndroidDevice();
return result;
}
#Override
protected void onProgressUpdate(Void... values) {}
#Override
protected void onPostExecute(String result) {
if (result != null && !result.equals("")) {
try {
JSONObject resObject = new JSONObject(result);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
3) Inside your onCreate method
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView("your layout");
if ("check here where network/internet is avaliable") {
new HTTPdemo().execute("");
}
}
The code snippet provided by me works in the following way,
1)Android device send the URL+data to server
2)Server [Azure platform used] receive the data and gives an acknowledgement
Now the Code which should be written at client side (Android) is provided to you, the later part of receiving that data at server is
Server needs to receive the data
An webservice should be used to do that
Implement an webservice at server side
The webservice will be invoked whenever android will push the URL+data
Once you have the data ,manipulated it as you want
