How to implement Facebook audience network banner ad in android app using Android Studio

Its very simple to implement Facebook audience network banner ad in android app using Android Studio. We will complete it in 4 Steps.

1. Creating Android Studio Project and adding Facebook Audience network dependency in the project
2. Adding layout for banner add in layout xml file
3. Initializing Facebook Audience network SDK and finally showing banner ad
4. Adding internet permission in Manifest file

1. Creating Android Studio Project and adding Facebook Audience network dependency in the project

Create an android studio project for creating an android app and wait for project build completion.
Now open build.gradle (App level) file and add the following dependency between dependencies section.
(At the time of writing this article this is the latest version)
implementation 'com.facebook.android:audience-network-sdk:5.6.1'

2. Adding layout for banner add in layout xml file

To show banner ad in our application, it needs any container which can hold the banner ad. So here we are using LinearLayout as a container. and we are giving its id as bannerAdContainerLinearLayout.

<LinearLayout  

   android:layout_width="match_parent" 

   android:orientation="vertical"    

   android:layout_alignParentBottom="true"    

   android:id="@+id/bannerAdContainerLinearLayout" 

   android:layout_height="wrap_content">
</LinearLayout>

3. Initializing Facebook Audience network SDK and finally showing banner ad

To show ads using Facebook Audience network in our application it is necessary that it should be initialized correctly. To initialize the Facebook Audience network SDK write the below code into your MainActivity.java OnCreate method.

AudienceNetworkAds.initialize(this);

//below statements are optional and will be used when you are testing your app and its not in release

//for testing only
AdSettings.setTestAdType(AdSettings.TestAdType.IMG_16_9_APP_INSTALL);
//for testing only
AdSettings.getTestAdType();
//for testing only
dSettings.addTestDevice("Device hash id");
Now we initialized the SDK, its time to load banner ad and show the ad
// creating adView object with our placement ID
AdView adView = new AdView(this, "IMG_16_9_APP_INSTALL#YOUR_PLACEMENT_ID", AdSize.BANNER_HEIGHT_50);
// finding linear layout container for banner which we have defined in our layout file
LinearLayout bannerAdContainer = findViewById(R.id.bannerAdContainerLinearLayout);
//adding adView to container

bannerAdContainer.addView(adView);
// loading our ad into adview and showing it to the user
adView.loadAd();

4. Adding internet permission in Manifest file

We will be able to show any ad to the user if our app has internet access permission.

So we have it add this permission into out AndroidManifest.xml file.

Add this line between <manifest> starting and closing tag

<uses-permission android:name="android.permission.INTERNET"/>




Now launch the application and we will see a test banner ad from facebook

Auto check for update function for android app | android studio

If you are having an app on Google Play Store and you want that whenever you update the app on playstore and when the user opens the older version of app he/she will get a dialog that there is an Update available .
Each time the user will open the app he/she will get the same dialog until he/she updates the app.

Advantages:

This will inform the user as a notice that there is an update.

Users will have the latest version of app.
Automatically checks for update in the background.
There is also an option for mannual check and automatic check.

How to use:

Step-I
I have already create a class(AppUpdateChecker.java) to achieve this feature that will handle it automatically.

AppUpdateChecker.java
 

 package com.programmingdesire;  
 import android.app.Activity;  
 import android.app.ProgressDialog;  
 import android.content.DialogInterface;  
 import android.content.Intent;  
 import android.content.pm.PackageInfo;  
 import android.content.pm.PackageManager;  
 import android.net.Uri;  
 import android.os.AsyncTask;  
 import android.support.v7.app.AlertDialog;  
 import android.widget.Toast;  
 import org.jsoup.Jsoup;  
 public class AppUpdateChecker {  
   private Activity activity;  
   public AppUpdateChecker(Activity activity) {  
     this.activity = activity;  
   }  
   //current version of app installed in the device  
   private String getCurrentVersion(){  
     PackageManager pm = activity.getPackageManager();  
     PackageInfo pInfo = null;  
     try {  
       pInfo = pm.getPackageInfo(activity.getPackageName(),0);  
     } catch (PackageManager.NameNotFoundException e1) {  
       e1.printStackTrace();  
     }  
     return pInfo.versionName;  
   }  
   private class GetLatestVersion extends AsyncTask<String, String, String> {  
     private String latestVersion;  
     private ProgressDialog progressDialog;  
     private boolean manualCheck;  
     GetLatestVersion(boolean manualCheck) {  
       this.manualCheck = manualCheck;  
     }  
     @Override  
     protected void onPostExecute(String s) {  
       super.onPostExecute(s);  
       if (manualCheck)  
       {  
         if (progressDialog!=null)  
         {  
           if (progressDialog.isShowing())  
           {  
             progressDialog.dismiss();  
           }  
         }  
       }  
       String currentVersion = getCurrentVersion();  
       //If the versions are not the same  
       if(!currentVersion.equals(latestVersion)&&latestVersion!=null){  
         final AlertDialog.Builder builder = new AlertDialog.Builder(activity);  
         builder.setTitle("An Update is Available");  
         builder.setMessage("Its better to update now");  
         builder.setPositiveButton("Update", new DialogInterface.OnClickListener() {  
           @Override  
           public void onClick(DialogInterface dialog, int which) {  
             //Click button action  
             activity.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id="+activity.getPackageName())));  
             dialog.dismiss();  
           }  
         });  
         builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {  
           @Override  
           public void onClick(DialogInterface dialog, int which) {  
             //Cancel button action  
           }  
         });  
         builder.setCancelable(false);  
         builder.show();  
       }else {  
         if (manualCheck) {  
           Toast.makeText(activity, "No Update Available", Toast.LENGTH_SHORT).show();  
         }  
       }  
     }  
     @Override  
     protected void onPreExecute() {  
       super.onPreExecute();  
       if (manualCheck) {  
         progressDialog=new ProgressDialog(activity);  
         progressDialog.setMessage("Checking For Update.....");  
         progressDialog.setCancelable(false);  
         progressDialog.show();  
       }  
     }  
     @Override  
     protected String doInBackground(String... params) {  
       try {  
         //It retrieves the latest version by scraping the content of current version from play store at runtime  
         latestVersion = Jsoup.connect("https://play.google.com/store/apps/details?id=" + activity.getPackageName() + "&hl=it")  
             .timeout(30000)  
             .userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6")  
             .referrer("http://www.google.com")  
             .get()  
             .select(".hAyfc .htlgb")  
             .get(7)  
             .ownText();  
         return latestVersion;  
       } catch (Exception e) {  
         return latestVersion;  
       }  
     }  
   }  
   public void checkForUpdate(boolean manualCheck)  
   {  
     new GetLatestVersion(manualCheck).execute();  
   }  
 }  

Step-II
Add a library to your build.gradle(App level) file.

   implementation 'org.jsoup:jsoup:1.10.2'  

Step-III
The last step is to copy that class and then write two lines of code.

 AppUpdateChecker appUpdateChecker=new AppUpdateChecker(this);  //pass the activity in constructure
 appUpdateChecker.checkForUpdate(false); //mannual check false here

Lets understand what is manual check

If manual check is true then
Manual check will be on a button click this will show the dialog as "Checking for update"

If manual  check is false then
Checking for update will be performed in the background and finally a dialog will be visible if there is any update.

 

If user will click on update it will open your app in playstore to update your app.

Thats all.

Thanks for visiting, I will come with new code snippet.

Happy Coding.......

How to insert images in C/ C++ using graphics(100% working)

Hello friends today we will learn how to insert images in  C++ language very easily using graphics. The things that are required for this work are listed here .....

1.Code blocks compiler installed on your system:

Code::Blocks is a free, open-source cross-platform IDE that supports multiple compilers including GCC, Clang and Visual C++. It is developed in C++ using wxWidgets as the GUI toolkit. Using a plugin architecture, its capabilities and features are defined by the provided plugins. Currently, Code::Blocks is oriented towards C, C++, and Fortran. It has a custom build system and optional Make support.(by wikipedia).

2.Graphics libraries should set up with code blocks:

When we install code blocks then there is no library and header file of graphics are given by the developers with it, so we have to configure these things manually.I come across a lots of videos on youtube to configure graphics in codeblocks and i found all the videos are just waste of time except one video and i learnt  from that video .It was a bit difficult for me to configure graphics in codeblocks.

This is why because i was getting the libraries and header file with bug.

So i thought to create a video on this topic on my own  :How to use graphics in codeblocks video

  If you did these two things then you can use this program or concept to insert images in C++ language using graphics in Codeblocks.

Here we go:

 #include<iostream>  
 #include<graphics.h>  
 int main()  
 {  
   initwindow(600,400,"Images");  
   readimagefile("image_name.jpg",0,0,600,400);  
   getch();  
   readimagefile("image_name.jpg",0,0,600,400);  
   getch();  
   return 0;  
 }  

Description of the program:

If you are using code blocks to make programs in graphics mode then we can make the programs in only C++ because in the graphics.h header file there is reference to iostream and if we work in C language then it will not link and then we get error in header file graphics.h. Download File

here we have used the two important predefinded functions of graphics they are....

• initwindow():this function is used to initialise a new window or you can say a  new window
• readimagefile():this is the function that is used to set images in our program.

readimagefile() takes five parameters the first parameter is the name of the image with extension of the image and the rest are the co-ordinates of the screen where to set.

Thanks for visiting ...we will come with new typical programs so stay connected.

How to insert image in c language in turboc IDE

Its been very interesting as well as difficult to work with graphics in c or c++ languages.
But it will be more interesting to work with image insertion in C or C++ language.

I have already created the post to insert image in c/c++ in codeblocks IDE but now its time to achieve this using Turbo C++ IDE.

 Befor writing code we have to take care of  these points.

• Create a  bmp(16 color Bitmap) image file using paint or any other image editor. 
• paste that file into bin folder of turbo c where this program will be saved.
• After pasting we will continue to write the below code.

 

 #include <alloc.h>  
   #include <conio.h>  
   #include <graphics.h>  
   #include <stdio.h>  
   #include <stdlib.h>  
   struct BMP  
   {  
    char Type[2];      //File type. Set to "BM".  
    unsigned long Size;   //Size in BYTES of the file.  
    unsigned long Reserved;   //Reserved. Set to zero.  
    unsigned long OffSet;  //Offset to the data.  
    unsigned long headsize; //Size of rest of header. Set to 40.  
    unsigned long Width;   //Width of bitmap in pixels.  
    unsigned long Height;   // Height of bitmap in pixels.  
    unsigned int Planes;  //Number of Planes. Set to 1.  
    unsigned int BitsPerPixel;    //Number of Bits per pixels.  
    unsigned long Compression;  //Compression. Usually set to 0.  
    unsigned long SizeImage; //Size in bytes of the bitmap.  
    unsigned long XPixelsPreMeter;   //Horizontal pixels per meter.  
    unsigned long YPixelsPreMeter;   //Vertical pixels per meter.  
    unsigned long ColorsUsed;  //Number of colors used.  
    unsigned long ColorsImportant; //Number of "important" colors.  
   };  
   int ShowBMP(int x, int y, char* FileName)  
   {  
     int b,a;  
     struct BMP Obj;  
     unsigned char* Datas;  
     int in=0;  
     unsigned char c=0;  
     FILE * fp;  
     fp = fopen(image.bmp,"rb"); //give filename of image with extension.  
     if(!fp){  
     printf("Error : Unable to open file ..");  
     exit(0);  
     }  
     fread(&Obj, sizeof(Obj), 1, fp);  
     if(Obj.BitsPerPixel!=4) // This isn't a 16 color bmp we can read;  
     {  
      fclose(fp);  
      printf("Error : File format not supported ..");  
      exit(0);  
     };  
     fseek(fp,Obj.OffSet,SEEK_SET);  
     Datas=(unsigned char*) calloc(Obj.Width/2+1, sizeof(unsigned char));  
     for(b=Obj.Height;b>=0;b--)  
     {  
      fread(Datas, sizeof(unsigned char), Obj.Width/2, fp);  
      c=0;  
      in=0;  
      for(a=0;a<=Obj.Width;a+=2)  
      {  
        c = (Datas[in] | 0x00) >>4;  
        putpixel(a+x,b+y,c);  
        c = (Datas[in] | 0xF0) & 0x0F;  
         putpixel(a+1+x,b+y,c);  
        in++;  
      }  
     }  
     free (Datas);  
     fclose(fp);  
     return 1;  
   }  
   void main()  
   {  
   int color;  
   int gd , gm ;  
   gd = VGA ; gm = VGAHI;  
   initgraph(&gd,&gm,"");  
   ShowBMP(0,0,"j.bmp"); /* Enter File Name Here */  
   getch();  
   closegraph();  
   }  

Now Run the code and you will get your image as output.
