Code:

public void onBackPressed() { if(){ } else{ } }

Code:

public void onBackPressed() { if (webView.canGoBack()) { webView.goBack(); } else { android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(this); builder.setMessage("Are you sure you want to Exit?") .setCancelable(false) .setPositiveButton("Yes", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { this.finishAffinity(); } }) .setNegativeButton("No", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { dialogInterface.cancel(); } }); android.app.AlertDialog alertDialog = builder.create(); alertDialog.show(); } } 

And see the below code so that you can understand where you have put the above Exit Dialog code.

Code:

package shorifaislam.shoppingmall; import androidx.appcompat.app.AppCompatActivity; import android.content.DialogInterface; import android.os.Bundle; import android.webkit.WebView; public class MainActivity extends AppCompatActivity { private WebView webView; private String url = "https://weblearners.blogspot.com/"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); webView = (WebView) findViewById(R.id.myweb); webView.loadUrl(url); } public void onBackPressed() { if (webView.canGoBack()) { webView.goBack(); } else { android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(this); builder.setMessage("Are you sure you want to Exit?") .setCancelable(false) .setPositiveButton("Yes", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { finish(); } }) .setNegativeButton("No", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { dialogInterface.cancel(); } }); android.app.AlertDialog alertDialog = builder.create(); alertDialog.show(); } } }  

Now you can run your project. You can see below the image we have successfully added Exit dialog on Home Screen. Exit dialog working perfectly.

That's it. Thank you.

The video tutorial of  "How to solve Manifest merger failed problem in Android Studio" is here

When your app will be suspended on google play store, the google play support team will send you an email about the reason for suspension. Like the below image.

In that email, you will see an option for contact with the support team for appeal.

As you see in the above image, my Webview App was suspended for Webviews and Affiliate Spam policy. First, you have to click on the support policy team. After clicking that you will get a form, there you have to 

In that form, First, click on check option, And First name, last name, primary email, and package name will automatically fill up, then you have to describe why they should remove the suspension, then you have to select the first option, then click submit. see the below image.

After submitting the form, they will send you an email for confirming you that they got an appeal from you successfully.

After 3-7 days later you will get an email from them again. In that email, they will give enough information about why they did suspension and what you should do for the removal of suspension.

As you can see my app suspended for webview and affiliate policy violation, they said if you are the owner of that website, then submit the screenshot of the website domain console.

After submitting the document they will remove the suspension from your Webview App and will send you a confirmation email. 

Then you have to update the app on Google Play Console. You can see my Webview App is now live on Google Play store. They Removed the suspension.

That's it. Thank you.

Buy traffic for your website

And then have to select the destination where you want to save the picture. And then drop your image. After resizing copy all the image folder and paste it in the drawable folder in Android studio. Please watch the above video and follow my step.

Hi, Today I am going to show How to Make Android App fit all Screen Sizes. Last Post I have shown you How to Integrate Admob ads in Webview. Let's Start.

Then you have to Make different files for different sizes of the display. Like in my project have a splash screen, I will make different activity file for different display sizes.

First, you have to click on the right side of the mouse, then select new-->Layout Resource File. Also, you have to give the exact same name which name has your default activity.xml file. In my case, my file name is "activity_splash.xml" in Webview App. I will provide that name in the file name scope, As you can see my splash screen has "RelativeLayout" so I have selected Root element RelativeLayout.

Then you can see on the left side has a "size" option, you need to click on that. you will see there has Small, Normal, Large, X-Large option. You have select which size you want. Then click on OK.


This way create other files. And for the landscape mode, you need to create also the same way but have written there "land" such as layout-small-land.


If you want to create a screen for a tablet, then you need to write layout-sw600dp. 600 dp used for small to 7-inch tablet screen support, for 10-inch or higher screen you need to create the same way 720dp.



Then copy the code from the original activity file, then paste the code in all the activity files in your Webview App. 

That's it. In the next video, the second part will be discussed which is about image fitting in Webview App according to the activity we have created here. If you face still a problem, Watch the video above and follow my guidelines. Thank you.
