Webview Fragments and back button

I am having trouble using the back button to go back in webview. I have 5 different fragments in a tab + swipe layout. Each having a different webview. I have my MainActivity.Java as well as a java file for each fragment. Using the examples shown in stackoverflow regarding this (can't link. Sorry) I get a force close whenever I press back on the app. So I received some helped and did a non-conventional stab at it but I get a couple of errors so I'm hoping one of you guys can help me out. I am super new to app development and java in general so please bear with me.
Here is my MainActivity.java where the errors are:
Code:

}

}
}
}
Error #1 is in line 26 and says:
Code:
The method tryGoBack() is undefined for the type WebViewFragment
Error #2 is in line 80 and says
Code:
Type mismatch: cannot convert from WebViewFragment to Fragment
Here is one of my fragment java files as well:
fragment1.java
Code:
package com.-----;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;

import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.view.Window;
import android.view.WindowManager;
import android.webkit.WebSettings;
import android.webkit.WebViewFragment;
public class fragment1 extends WebViewFragment {
public abstract class WebViewFragment extends Fragment{
public abstract void tryGoBack();
}
WebView myWebView;
[user=439709]@override[/user]
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.fragment1, container, false);
myWebView = (WebView) root.findViewById(R.id.webview1);
myWebView.setWebViewClient(new WebViewClient());
myWebView.loadUrl("url");
return root;
}
}
Any help is greatly appreciated!

When dealing with two or different classes which all extend one of them, so in this case the WebViewFragment extending Fragment and your fragment1 inheriting from WebViewFragment, you can convert the object simply putting
Code:
(NewType)
in front of it. So for error 1, insert (Fragment1) and for error 2 insert (Fragment).
One advice I'd like to give you, Capitalize class names and don't capitalize object and variable names, so it should be Fragment1 (maybe a more clear name) and WebViewFragment fragment.

(Q) Load Custom system font from Extend TextView class.

Hello everyone.
i am trying to load a custom font from /system/fonts i use a custom extend TextView class

How do I change text in card views list?

I'm trying to update the text in my card view. I cannot figure out how to do it. I posted the code of my recyclerAdapter class below.
When a user clicks a card view it should update the text on the card view with a specified time.
Code:
package com.teamtreehouse.oslist;
import java.util.ArrayList;
import android.support.v7.widget.RecyclerView;
import android.util.Log;
import android.net.Uri;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.view.LayoutInflater;
import java.util.Calendar;
import android.content.Intent;
import java.text.SimpleDateFormat;
import java.util.Locale;
public class RecyclerAdapter extends RecyclerView.Adapter<FaucetHolder>
{
private ArrayList<Faucet> faucets;
private Context context;
private SharedPreferences sharedPref;
private String dateFormat = "h:mm a";
public RecyclerAdapter (ArrayList<Faucet> faucetsI,Context context) {
this.faucets = faucetsI;
this.context=context;
}
@Override
public FaucetHolder onCreateViewHolder(ViewGroup viewGroup, int i)
{
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.card_view,viewGroup,false);
FaucetHolder f = new FaucetHolder(v);
return f;
}
@Override
public void onBindViewHolder(FaucetHolder f, int k)
{
final Faucet faucet = faucets.get(k);
f.titleText.setText(faucet.getName());
f.titleText.setOnClickListener(new View.OnClickListener() {
public void onClick(View btn) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(faucet.getLink()));
setRenewal(faucet);
context.startActivity(intent);
}
});
}
@Override
public int getItemCount()
{
return faucets.size();
}
private void setRenewal(Faucet g) {
sharedPref = context.getSharedPreferences("myPref",0);
SharedPreferences.Editor edit = sharedPref.edit();
Calendar c = Calendar.getInstance();
long current = c.getTimeInMillis();
long future = current + g.getLength();
c.setTimeInMillis(future);
SimpleDateFormat df = new SimpleDateFormat(dateFormat,Locale.US);
String date = df.format(c.getTime());
edit.putString(g.getSPName(),date);
}
private void updateText(FaucetHolder f, Faucet g) {
sharedPref = context.getSharedPreferences("myPref",0);
String updatedTime = sharedPref.getString(g.getSPName(), null);
f.timeText.setText(updatedTime);
}
}

The full error text would be helpful. If you haven't done it before you can quickly check if something is wrong with your views in the adapter bei commenting them out.

[App]Notification notified on Emulator but not visible on Phone

Hi Everyone! I was working on an app, which needed to give a remainder on a certain time, by triggering a notification. The app seemed to work fine on the emulator. But, the notification never shows up on a real phone.
The service which sends the broadcast.
Code:
package com.example.tanmay.yourdiary;
import android.annotation.TargetApi;
import android.app.IntentService;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.app.TaskStackBuilder;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.os.IBinder;
import android.support.annotation.Nullable;
import android.support.v4.app.NotificationCompat;
import android.support.v4.content.LocalBroadcastManager;
import android.util.Log;
import java.text.SimpleDateFormat;
import java.util.Calendar;
/**
* Created by Tanmay on 22-01-2016.
*/
public class MyService extends IntentService {
public MyService() {
super("com.example.tanmay.yourdiary");
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
final Context context = this;
final Intent i = new Intent("com.example.tanmay.yourdiary.MyReceiver");
i.setAction("com.example.tanmay.yourdiary.MyReceiver");
new Thread(new Runnable(){
public void run(){
while(true){
Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
String g="";
g=sdf.format(c.getTime());
Log.i("dd",g);
if(g.equals("05:23")){
Log.i("d3d",g);
LocalBroadcastManager.getInstance(context).sendBroadcast(i);
try {
Thread.sleep(24*60*60*1000);
stopSelf();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
try {
Thread.sleep(20000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
return START_STICKY;
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
protected void onHandleIntent(Intent intent) {
}
}
The receiver
Code:
package com.example.tanmay.yourdiary;
import android.annotation.TargetApi;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.TaskStackBuilder;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.support.v4.app.NotificationCompat;
import android.util.Log;
public class MyReceiver extends BroadcastReceiver {
public MyReceiver() {
}
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
@Override
public void onReceive(Context context, Intent intent) {
// TODO: This method is called when the BroadcastReceiver is receiving
// an Intent broadcast.
Log.i("dfdfg", "bc rec");
NotificationCompat.Builder builder = new NotificationCompat.Builder(context).setSmallIcon(R.drawable.ic_launcher).setContentTitle("Reminder").setContentText("Time to write your thoughts!");
TaskStackBuilder taskstackbuilder = TaskStackBuilder.create(context);
taskstackbuilder.addParentStack(MainActivity.class);
Intent i = new Intent(context,Writing.class);
taskstackbuilder.addNextIntent(i);
PendingIntent ip = taskstackbuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(ip);
NotificationManager manager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(1,builder.build());
}
}

Try this code to see if it works on your phone or not
Code:
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mContext)
.setSmallIcon(R.drawable.ic_launcher).setContentTitle("Title").setContentText("Description text");
Intent resultIntent = new Intent(mContext, MainActivity.class);
resultIntent.putExtra(AN_ADITIONAL_EXTRA, "User clicked on the notification");
// Because clicking the notification opens a new ("special") activity, there's no need to create an artificial back stack.
PendingIntent resultPendingIntent = PendingIntent.getActivity(mContext, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
mBuilder.setAutoCancel(true);
// Sets an ID for the notification
int mNotificationId = 10; // give it an ID you recognize within your application
// Gets an instance of the NotificationManager service
NotificationManager mNotifyMgr = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
// Builds the notification and issues it.
mNotifyMgr.notify(mNotificationId, mBuilder.build());
And in your MainActivity.class under onNewIntent / onCreate
if(getIntent.getExtras() != null){
if(intent.hasExtra(AN_ADITIONAL_EXTRA)){
// User clicked on the notification, do something
}
}
