How to delete messages from firebase Database?

How to delete messages from firebase Database? - java

I am working on a chat application connected to firebase. I am trying to add a future where I can delete a message. This is what I have tried but it's not working.
This is the code
...package com.sollie.ian.eunice.ui

}
}
class ItemMessageFriendHolder extends RecyclerView.ViewHolder {

public CircleImageView avata;
public ItemMessageFriendHolder(View itemView) {
super(itemView);
txtContent = itemView.findViewById(R.id.textContentFriend);
avata = itemView.findViewById(R.id.imageView3);
}
}
And this is what I have tried
private void deleteMsg(int position) {
final String myuid = FirebaseAuth.getInstance().getCurrentUser().getUid();
String msgtimestmp =String.valueOf(consersation.getListMessageData().get(position).timestamp);
String message=consersation.getListMessageData().get(position).text;
DatabaseReference roofRef=FirebaseDatabase.getInstance().getReference();
roofRef.child("message").child(message)
.removeValue().addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if(task.isSuccessful())
{
Toast.makeText(context, "deleted", Toast.LENGTH_SHORT).show();
}else
{
Toast.makeText(context, "failed", Toast.LENGTH_SHORT).show();
}
}
});
}
What am I doing wrong?

The problem is here:
String message=consersation.getListMessageData().get(position).text;
DatabaseReference roofRef=FirebaseDatabase.getInstance().getReference();
roofRef.child("message").child(message).removeValue()
You're trying to delete the message based on its text, but to delete a node from Firebase you need to know its key.
This means that when you read the messages from the database, you'll need to store dataSnapshot.getKey() for each message (probably as a field in your Message class). Then when you are ready to delete the message, you can get the key from that class and pass it into the database call, with something like:
String key= consersation.getListMessageData().get(position).key; // 👈
DatabaseReference roofRef=FirebaseDatabase.getInstance().getReference();
roofRef.child("message").child(key).removeValue()... // 👈

Why is this happening ,and why is it a Long instead of being a list and causing all this issues?

The problem is that the data is of Long class and you are trying to cast it to List
What you should try is
Map<String, Object> followerMap= new HashMap<>();
followerMap= value.getData();
assert followerMap!= null;
for (Map.Entry<String, Object> e : followerMap.entrySet()) {
long following= e.getValue();
followingList_2 .add(following);
}

AppWidget is frozen before message has been sent or recieved. How to initiate the intent before messages are sent?

So appwidget is fixed after some help on here but before any message has been sent or received the intent to launch the ChatRoomActivity doesn't work.
How could I set it up so it's intent launches the activity before any message has been sent/received(obviously it would have no message but it has a textView saying click to open chat..etc).
my code:
public class ProTalkWidget extends AppWidgetProvider {
private static final String ACTION_BROADCASTWIIDGET = "ACTION_BROADCASTWIIDGET";
public static final String PROTALK_APPWIDGET_UPDATE = "PROTALK_APPWIDGET_UPDATE";
private final int REQUEST_CODE = 0;
public static final String USER_ID = "userId";
DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
FirebaseAuth mAuth = FirebaseAuth.getInstance();
String msgReceiverId;
private void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
final int appWidgetId) {
//Construct the RemoteViews object
final RemoteViews views;
views = new RemoteViews(context.getPackageName(), R.layout.pro_talk_widget);
Intent intent = new Intent(context, ProTalkWidget.class);
intent.setAction(ACTION_BROADCASTWIIDGET);
context.sendBroadcast(intent);
appWidgetManager = AppWidgetManager.getInstance(context);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if(PROTALK_APPWIDGET_UPDATE.equals(intent.getAction())){
Log.i("onReceive", "getting onReceived!");
handleMsg(intent, context);
}
}
private void handleMsg(final Intent intent, final Context ctx){
msgReceiverId = intent.getStringExtra("receiverId");
if(msgReceiverId!=null) {
String my_Id = mAuth.getCurrentUser().getUid();
final RemoteViews views;
views = new RemoteViews(ctx.getPackageName(), R.layout.pro_talk_widget);
DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
Query query = rootRef.child("Messages").child(my_Id).child(msgReceiverId).limitToLast(1);
ValueEventListener valueEventListener = new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot ds : dataSnapshot.getChildren()) {
Messages messages = ds.getValue(Messages.class);
String message = messages.getMessage();
String from = messages.getFrom();
Log.d("TAG", message + "+" + from);
views.setTextViewText(R.id.appwidget_message, message);
Intent mainIntent = new Intent(ctx, ChatRoomActivity.class);
if(msgReceiverId != null)
mainIntent.putExtra("profile_view_userId", msgReceiverId);
mainIntent.putExtra("username", "Ben");
PendingIntent mainPendingIntent = PendingIntent.getActivity(ctx, REQUEST_CODE, mainIntent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.widget_layout, mainPendingIntent);
AppWidgetManager.getInstance(ctx).updateAppWidget(new ComponentName(ctx, ProTalkWidget.class), views);
}
}
#Override
public void onCancelled(DatabaseError databaseError) {}
};
query.addListenerForSingleValueEvent(valueEventListener);
}
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
// There may be multiple widgets active, so update all of them
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
#Override
public void onEnabled(Context context) {
// Enter relevant functionality for when the first widget is created
}
#Override
public void onDisabled(Context context) {
// Enter relevant functionality for when the last widget is disabled
}
}
Please note intent and displaying message works after chatroomactivity has been opened and message sent.

Working with Sinch Instant Messaging System

I am using Sinch and Parse for my instant messaging system integrated in our application, and I have two concerns.
1) For some reason, I am receiving the following error when the messaging activity is displayed: The message client did not start". Furthermore, the message does not seem to go through in Sinch and not reflected visually in the application.
Below is the activity code (when the user clicks on the "quick chat" button, it takes them to the messaging activity page.
Below is the activity code for the messaging activity
public class MessagingActivity extends Activity implements ServiceConnection, MessageClientListener {
private String recipientId;
private Button sendButton;
private EditText messageBodyField;
private String messageBody;
private MessageService.MessageServiceInterface messageService;
private MessageAdapter messageAdapter;
private ListView messagesList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.messaging);
doBind();
messagesList = (ListView) findViewById(R.id.listMessages);
messageAdapter = new MessageAdapter(this);
messagesList.setAdapter(messageAdapter);
Intent intent = getIntent();
recipientId = intent.getStringExtra("Name");
messageBodyField = (EditText) findViewById(R.id.messageBodyField);
sendButton = (Button) findViewById(R.id.sendButton);
sendButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
sendMessage();
}
});
}
private void sendMessage() {
messageBodyField = (EditText) findViewById(R.id.messageBodyField);
messageBody = messageBodyField.getText().toString();
if (messageBody.isEmpty()) {
Toast.makeText(this, "Please enter a message", Toast.LENGTH_LONG).show();
return;
}
//Here is where you will actually send the message throught Sinch
messageService.sendMessage(recipientId, messageBody);
messageBodyField.setText("");
}
private void doBind() {
Intent serviceIntent = new Intent(this, MessageService.class);
bindService(serviceIntent, this, BIND_AUTO_CREATE);
}
#Override

}
#Override

//Define the messaging service and add a listener
messageService = (MessageService.MessageServiceInterface) iBinder;
messageService.addMessageClientListener(this);
if (!messageService.isSinchClientStarted()) {
Toast.makeText(this, "The message client did not start."
,Toast.LENGTH_LONG).show();
}
}
#Override
public void onServiceDisconnected(ComponentName componentName) {
messageService = null;
}
#Override
public void onMessageDelivered(MessageClient client, MessageDeliveryInfo deliveryInfo) {

}
#Override

//Notify the user if message fails to send
Toast.makeText(this, "Message failed to send.", Toast.LENGTH_LONG).show();

I have verified that the APP_KEY, the APP_SECRET and ENVIRONMENT matches what was recorded on Sinch.
I have tried this both on the emulator, and on a physical device.
Thanks in advance

2) Limit: I would like to set a limit, where a only 25 messages would be available between a particular party.
Thanks in advance, and if you need any clarification, let me know.
Update 3
When user clicks on this button, he is taking to the MessagingActivity with the person he has been matched to based upon the below criteria
final Button ibutton = (Button) this.findViewById(R.id.btnQuickChat);
idrinks.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
openConversation();
}
private void openConversation() {

I wrote the tutorial you're following, and actually just updated it yesterday to fix your first problem. Check out http://tutorial.sinch.com/android-messaging-tutorial/#show-spinner to see the updates. Instead of showing a toast message when the service is not started, the new version will show a progress dialog (loading spinner) until the service has either started or failed to start.
Could you clarify your second question?

Just declare your service in manifest. I had the same problem and it solved it.
