Develop Reference

Paytm All in one SDK not working in release more or after publishing to Play store

I have integrated PAYTM ALL IN ONE SDK to my android app. It is working fine in debug mode but in release mode it is throwing exception. There is small thing that i am missing because its working absolutely fine in debug mode but changing it to release it is throwing exception.

This is because of the new R8 code obfuscation. You need to disable it from your project by adding below line to the gradle.properties file -
android.enableR8=false
Also you need to add below lines to your proguard rules file -
# Prevent R8 from leaving Data object members always null
-keepclassmembers,allowobfuscation class * {
#com.google.gson.annotations.SerializedName <fields>;
}

CustomAlertDialog doesn't finish its process after deleting a record of databse

I am using my CustomAlertDialog in order to delete a record from database, when I delete one successfully and I attempt to insert a new row into database, the AlertDialog appears again notwithstanding I didn't even call it and when I click the delete button it deletes one record until all the records are deleted and app crashes.
I call it on my AdapterClass =>
#Override
public void onClick(View view) {
E04Object obj = object.get(getAdapterPosition()) ;
id = obj.getId() ;
if (view == deleteBtn) {
int position = id ;
if (position != RecyclerView.NO_POSITION) {
activityReference.ShowDialog(position);
}
clicked = false ;
} }
and I initialize it in my FragmentClass =>
#Override
public void ShowDialog(int position) {
DialogObject dialogObject = new DialogObject() ;
CustomDialogView customDialogView = new CustomDialogView(getActivity() , dialogObject) ;
dialogObject.setListener(new DialogListener() {
#Override
public void onPositive() {
dbConnector.get().execSQL(
" DELETE FROM " + db.Tables.MYDB + " WHERE " + db.MYDB.ID + " = " + position );
customDialogView.hide();
list.remove(MyAdapter.cardId) ;
adapter.notifyDataSetChanged();
}
#Override
public void onNegative() {
customDialogView.hide();
}
});
customDialogView.setCancelable(true);
customDialogView.show();
}

#Override
public void ShowDialog(int position) {
DialogObject dialogObject = new DialogObject() ;
CustomDialogView customDialogView = new CustomDialogView(getActivity() , dialogObject) ;
dialogObject.setListener(new DialogListener() {
#Override
public void onPositive() {
dbConnector.get().execSQL(
" DELETE FROM " + db.Tables.MYDB + " WHERE " + db.MYDB.ID + " = " + position );
customDialogView.dismiss();
list.remove(MyAdapter.cardId) ;
adapter.notifyDataSetChanged();
}
#Override
public void onNegative() {
customDialogView.dismiss();
}
});
customDialogView.setCancelable(true);
customDialogView.show();
}

customDialogView.hide();
replace code with this
customDialogView.dismiss();

on child added method work multiple times

I am making a challenge between two users in my app using firebase database. in the challenge I store player1Uid and player2Uid(player1 is the player who started the challenge and player two is the player who will accept or refuse the challenge). I want to make a history of challenges so If the challenge is completed I store it in a list called"completedChallengesList" and if the challenge isn't completed yet I store it in a list called uncompleted challenge list.the code some times work fine but in other times it bring the data more than one time to the list.
this is my code that brings data :
public void startAsynkTask() {
//TODO : search for a solution to this error
AsyncTask asyncTask = new AsyncTask() {
#Override
protected Boolean doInBackground(Object[] objects) {
try {
Socket sock = new Socket();
sock.connect(new InetSocketAddress("8.8.8.8", 53), 1500);
sock.close();
return true;
} catch (IOException e) {
return false;
}

//TODO : note that the only changing handled is when challenge moves from uncompleted to completed state
getChallengeData(dataSnapshot, "onChildChanged");
for (int i = 0; i < uncompletedChallengesList.size(); i++) {
if (uncompletedChallengesList.get(i).getId().equals(dataSnapshot.getKey())) {
uncompletedChallengesList.remove(i);
view.notifyAdapters(completedChallengesList.size(), uncompletedChallengesList.size());
break;

}
};
//this code gives data where current user is player 1
player1Listener = challengesReference.orderByChild("player1Uid").equalTo(currentUserUid).addChildEventListener(generalChallengesListener);

}

if (challenge.getState().equals("اكتمل")) {

if(!completedChallengesList.contains(challenge)) {

}
view.notifyAdapters(completedChallengesList.size(), uncompletedChallengesList.size());

if(!uncompletedChallengesList.contains(challenge)) {
uncompletedChallengesList.add(0, challenge);
}
view.notifyAdapters(completedChallengesList.size(), uncompletedChallengesList.size());
}
return player1Uid;
}
after long time of debugging I found that the method getChallengeData() is called more than one time when a new child added . I tried a lot to know why but I couldn't.
NOTE : I am using asynk task to check if there is internet connection or no before start loading data.

I think that your problem is, you are not removing your listner "generalChallengesListener", so multiple refereces will be created, so the onChildAdded will be excuted multiple times as the number of listners you created. So add a reference to your lister and know when you should remove it.
Hope it will helps you =)

Trouble getting getItem on an object in a RecyclerAdapter

I'm currently having some trouble getItem in the RecyclerAdapter on my Photo class. I tried adding
public int getItem(int pos){
return getItem(pos);
}
but that did not seem to work it. How can i getItem(position) without it having errors? (If i have not elaborated enough please say.)
Here is my code so you can tell me what i am doing wrong.

You function calls itself:
public int getItem(int pos){
return getItem(pos);
}
To fix the problem you should do several things:
1) You adapter should have collection of Photo objects. E.g. ArrayList list;
It should be filled from maybe Countructor. So, your adapter should have constructor containing this list.
2) Change getItem method to this :
public Photo getItem(int pos){
return list.get(pos);
}

First of all, your getItem function should return an object (i guess).
Also Honestly I am little confused what u r trying to accomplish and I thought You wanted to get an item in a specific position in your recycler view right?
In your Viewholder class just add below code
int position = 0;
In your OnBindViewHolder Function in the RecyclerViewAdapter, there is a position of each item in your recyclerview
public void onBindViewHolder(RecyclerViewAdapter.MyViewHolder holder, int position) {
Model yourModel= modelList.get(position);
holder.position = position;
}
Besides if you are trying to get OnClickListener in your recyclerview. The Following way may be useful. Create Interface
public interface RecyclerViewOnItemClickListener {
void OnItemClickListener(View view, int position);
void OnItemLongClickListener(View view, int position);
}
This code goes into RecyclerAdapter Class
public void setOnItemClickListener(RecyclerViewOnItemClickListener OnItemClickListener){
this.recyclerViewOnItemClickListener = OnItemClickListener;
}
Final Step in your Main activity or your fragment that you wanna show the recyclerview
recyclerViewAdapter.setOnItemClickListener(new RecyclerViewOnItemClickListener() {
#Override
public void OnItemClickListener(View view, int position) {
Model yourModel= modelList.get(position);
}
#Override
public void OnItemLongClickListener(View view, int position) {
}
});
Here is how you can get the item in a specific position.
Hope this helps ;)

Please help me with the possible solutions i am quite new in Android Development

Your error is coming from OkHttp.
If you search for the error message, you can see where OkHttp is generating it:
https://github.com/square/okhttp/blob/master/okhttp/src/main/java/okhttp3/Request.java#L142
HttpUrl parsed = HttpUrl.parse(url);
if (parsed == null) throw new IllegalArgumentException("unexpected url: " + url);
return url(parsed);
It means that your URL is invalid. As the comment to your question points out: >http://192.168.2.20:8080/jagteraho/batteryStatus/save is not a valid URL.
You need to remove the >.
