Google Play: update prices from IInAppBillingService

I created a class for working with subscriptions in the store.
In the beginning I receive from the server the list of subscriptions with the prices
The code is working and on most devices there is no problem.
But some users do not recive prices. It's like there's no response from the server. I've studied examples of implementation in Google documentation, but I can not understand where I can have problems in the code.
Part of my code:
public class BillingActivity extends AppCompatActivity {
RelativeLayout imageLayout;
View payButton;
// WebView payWebView;
// TextView useCodeButton;
ProgressBar progress1;
ProgressBar progress2;
ProgressBar progress3;
IInAppBillingService inAppBillingService;
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_billing_subscription);
price_1monthTextView = (TextView) findViewById(R.id.price_1monthTextView);
relative_1month = (RelativeLayout) findViewById(R.id.relative_1month);
relative_1month.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (MainActivity.myAccount == null) return;
if (MainActivity.myAccount.getUniqid() == null) return;
if (subscription1m != null) {
try {
Log.d("my", "purchase..." + subscription1m.storeName);
purchaseProduct(subscription1m);
} catch (Exception e) {
e.printStackTrace();
Log.d("my", "purchase error = " + e.toString());
}
}
}
});
progress1 = (ProgressBar) findViewById(R.id.progress1);
startGoogleBilling();
}
private void startGoogleBilling() {
if (serviceConnection != null) {
unbindService(serviceConnection);
}
progress1.setVisibility(View.VISIBLE);
serviceConnection = new ServiceConnection() {

price_1monthTextView.setText(subscription1m.price);
price_3monthTextView.setText(subscription3m.price);
price_1yearTextView.setText(subscription1y.price);
}
}
}

my problem was the bit depth of the X variable priceAmountMicros
The price from playmarket is multiplied by a 1000000 , and Kazakh tenge has exchange rate = 1 USD= 331,3 KZT.
And if i have price 18 000 KTZ and * 1000 000.
For price variable I must use long type

Android Database in AsyncTask in Fragment

I have a DbHelper Class which extends SQLiteOpenHelper.
I do Some Download and update the Database inside an Asynctask.
Inside an activity i got no problem and code works fine,
but when i use the ASynctask class inside a fragment problems occurs.
usually wherever i use a context an Exception happened, Especially with dbHelper.ClearDB()
Error:
DB Read ERROR:java.lang.NullPointerException:
Attempt to invoke virtual method 'java.util.ArrayList x.database.DBHelper.getAllItems()' on a null object reference
Here's the code :
public class StaggeredFragment extends Fragment

}
private void InitialsJson(String fetched) throws JSONException

disItem.setLiked(preferences.getBoolean(String.valueOf(disItem.getPid()), false));
Log.d(TAG, disItem.toString());
dbHelper.insert(disItem);
}
}
}
This is Databace getallItems function
public ArrayList<DisItem> getAllItems()
{
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery("select * from " + DIS_TABLE_NAME + "", null);
ArrayList<DisItem> arrayList = new ArrayList<>();
cursor.moveToFirst();
while (! cursor.isAfterLast())
{
DisItem disItem = new DisItem(cursor);
arrayList.add(disItem);
cursor.moveToNext();
}
return arrayList;
}

I tried your code with same scenario in a small JUnit Test and it shows me that you have not initialized your ArrayList<DisItem> correctely in getAllItems() method may be thats why you are getting nullPointerException that is
Replace
ArrayList<DisItem> arrayList = new ArrayList<>();
With
ArrayList<DisItem> arrayList = new ArrayList<DisItem>();'
I corrected this thing and run the test again with some dummy values and it showed me correct result like:
public class Test
{
private ArrayList<DisItem> savedData;
#org.junit.Test
public void test() throws Exception
{
savedData = getAllData();
for(int a = 0; a < savedData.size(); a++){
System.out.println("ArrayList Data A= " + savedData.get(a).getA() + " B = " + savedData.get(a).getB());
}
}
}
private ArrayList<DisItem> getAllData()
{
ArrayList<DisItem> arrayList = new ArrayList<DisItem>();
DisItem disItem = new DisItem();
disItem.setA("AAAAAA");
disItem.setB("BBBB");
arrayList.add(disItem);
return arrayList;
}
private class DisItem
{
String a, b;
public void setA(String a)
{
this.a = a;
}
public void setB(String b)
{
this.b = b;
}
public String getA()
{
return this.a;
}
public String getB()
{
return this.b;
}
}
Output:
ArrayList Data A= AAAAAA B = BBBB

you cant access more than one SharedPreferences or SQLiteOpenHelper in Parallel.

How to use returned arraylist?How to retrieve data from arraylist?

In the following code,i am saving the three values fun_id,fun_logo,fun_req with the help of another class Use.In the code an arraylist is returned,now i want to retrieve the fun_id,fun_logo,fun_req.I want to add fun_logo into imagearray.I would like to know how to use the Class Use for retreving data.I am learning currently so only small idea bout android.
ArrayList<Use> stringArrayList = null;
ArrayList<Use> res = null;
ArrayList<String> linklist = null;
String getdetailsurl;

list.setAdapter(adapter);
}
public class Getdetailsfromweb extends AsyncTask<String,Void,String>

String result = "";
#Override
protected String doInBackground(String... params) {
getdetailsurl=Webcall.getdet();
if(getdetailsurl!=null)
{
result = "Success";
}
else
{
result = "Failure";
}
return result;
}
#Override
protected void onPostExecute(String result) {
res = new ArrayList<Use>();
try {
if (result.contentEquals("Success"))
{
res=passdetails();
System.out.println("lsize is " + res.size());
for(int i=0;i<res.size();i++)
{
// To retreive value what should i do here
imagearray[i]=obj.funlogo;
System.out.println("logo is " + imagearray[i]);
}
}
else
{
}
} catch (Exception e1) {
e1.printStackTrace();
}
}
public ArrayList<Use> passdetails()
{
JSONArray array = null;
stringArrayList = new ArrayList<Use>();
linklist= new ArrayList<String>();
Use usee;
try {
array = new JSONArray(getdetailsurl);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for(int i = 0;i <array.length() ;i++ )
{
String fun_id= null;
String fun_logo= null;
String fun_req = null;
try {
fun_id = array.getJSONObject(i).getString("up_id");
System.out.println("up_id is " + fun_id);
fun_logo=array.getJSONObject(i).getString("logo");
System.out.println("logo is " + fun_logo);
fun_req=array.getJSONObject(i).getString("requirements");
System.out.println("req is " + fun_req);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
usee=new Use();
usee.funid=fun_id;
System.out.println("fun is " + usee.funid);
usee.funlogo=fun_logo;
System.out.println("fun is " + usee.funlogo);
usee.funreq=fun_req;
System.out.println("fun is " + usee.funreq);
linklist.add(fun_logo);
stringArrayList.add(usee);
}
return stringArrayList;
}
}
Use.java
public class Use {
public static String funid;
public String funlogo;
public String funreq;
}

I would like to know how to use the Class Use for retrieving data
All fields are public in Use and res is ArrayList of object of Use class. access values from each object as :
for(int i=0;i<res.size();i++)
Use useObj=res.get(i);
String funlogo=useObj.funlogo;
String funreq=useObj.funreq;
...
}

Define a Use class with getter and setter methods.
Define a method getFunLogos() in Use class which would return the image array of all the fun logos. Access this method from wherever you want.
protected String[] getFunLogos(ArrayList<Use> listFunLogos) {
for(int i=0;i<res.size();i++)
{
// To retreive value what should i do here
imagearray[i]=obj.funlogo;
System.out.println("logo is " + imagearray[i]);
}
}

I want to add fun_logo into imagearray
//linklist : as you are adding fun_log in it
imagearray=new String[linklist.size()];
linklist.toArray(imageArray);

List ImageView repeating same image when shared

I have a listView that is supposed to accept a shared message and image where the image is placed within the ImageView. This feature works for just the first message, but once an image is shared, each message received after that initial one becomes a copy of that same image even though the blank image placeholder was already set, which is just a one pixel black png:
holder.sharedSpecial.setImageResource(R.drawable.image_share_empty_holder);
An example is below:
The green textbox is the recipient. They have recieved a shared image from the yellow textbox. The yellow textbox then simply sends a normal message and I have set another image as a placeholder for normal messages: holder.sharedSpecial.setImageResource(R.drawable.image_share_empty_holder);
The same previously shared image takes precedence. I have used notifyDataSetChanged() so as to allow for the updating the adapter so that it would recognize not to use the same image, but to no avail.
How can I reformulate this class so that the image shared is only displayed with the proper message and not copied into each subsequent message?

I have gone through your code and this is common problem with listview that images starts repeating itself. In your case I think you have assigned image to Imageview every if and else if condition but if none of the condition satisfy it uses the previous image.
I would suggest to debug the getview method and put break points on the setImageResource. I use volley for these image loading and it has a method called defaultImage so that if no url is there the image is going to get the default one. So add that default case and see if it works.
If any of the above point is not clear feel free to comment.

Android Progress Dialog Set Message From a Class File

I have the following code that downloads a video using AsyncTask.
//DOWNLOAD VIDEOS
private class downloadVideosAsync extends AsyncTask <String, String, String>{
protected void onPreExecute(){
super.onPreExecute();
MyActivity.this.mProgressDialog.setMessage("Downloading Videos...");
}
#Override
protected String doInBackground(String... strings){
try{
VideosC.downloadVideos( VideosM.getVideoNames(), VideosM.getVideoUrls(),
VideosM.getVideoThumbs(), VideosM.getFileModified() );
}catch (NullPointerException e){
Log.e(LOG_TAG, e.toString());
}catch(Exception e){
Log.e(LOG_TAG, e.toString());
}
return null;
}
#Override
protected void onPostExecute(String lenghtOfFile) {
new downloadSlideshowsAsync().execute();
}
}
As you can see I have set the message "Downloading Videos..." for my progress dialog. Now what I want to do is something like setMessage("Downloading 1 of 5"). But the problem is my downloadVideos function is in another class file VideosController.java
public void downloadVideos( ArrayList<String> VideoNames, ArrayList<String> VideoUrls,
ArrayList<String> VideoThumbs, ArrayList<String> fileModified){
try{
int x;
int videoNamesLenght = VideoNames.size();
File vidFile;
for(x = 0; x < videoNamesLenght; x++) {
String[] videoName = VideoNames.get(x).split("/");
String currentFile = videoName[0] + "." + videoName[1];
String currentFileURL = VideoUrls.get(x) + VideoNames.get(x);
Log.v(LOG_TAG, "currentFileURL: " + currentFileURL);
vidFile = new File(Environment.getExternalStorageDirectory()
+ "/MyApp/Downloads/Videos/", currentFile);
//I want to do maybe here something like
//mProgressDialog.setMessage("Downloading x of y")
downloadVideoFile(currentFile, currentFileURL, vidFile, fileModified.get(x));
}
}catch(Exception e){
Log.e(LOG_TAG, e.toString());
}
}
Any ideas? Thanks a lot for any help! :)

You can define a static function in Activity which call the VideosController.
In that function you can send Handler Message and handle it.
