Usually, the display of mobile devices becomes small, normal, large, x-large. For fitting all these screen sizes, you need to also give these sizes of images. For doing this I will use the software, you can Download image Resizer


In the software First, you have to select the size format from the left side, such as mdpi, hdpi, xhdpi, tvdpi etc. then you need to select drawable from the drop-down menu. 

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.

How to Make Android App fit all Screen Sizes | Webview App Development Series Part 14

April 27, 2020 1 Comments
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.



First, you have to go to the "AndroidManifest.xml" file for giving permission to Make Android App fit all Screen Sizes. Usually, the display of the mobile becomes small, normal, large, x-large. So, we will give all-screen supports permission. Write the following code.

Code:


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.

App Crash Without Any Error in Code || How to Fix || Android Studio || 2020

April 25, 2020 0 Comments
Hi, Is your Android App  or Webview App getting crash on Android Studio? Also, there is no error showing in the code? 

I am going to show the simplest and easiest way to finding the reason for app crashing and also the solution. For getting useful videos, Please subscribe to my youtube channel.


You can see in the above video, my app is crashing when I am running my Webview App on Android Studio. you can see no errors appear in my code, but my app is crashing. 

For finding the reason first click on the "Logcat" from the android studio, then you will see there is opened a window. There you will select your device, then select your project, then select the "Error".

You can see there is an "Underlined Blue color word", click on that it will show the file name and the code line number where you have an error. There will also show you the reason why your app is crashing. In my case, I have a problem in the "MainActivity.java" file on 125 number line code,  My Webview App is crashing for a null object reference.


Because I have taken a variable, but I have not initialized it in OnCreate, also I have not stored my layout design o that variable but I have written function using that variable, So it is showing null object reference. 

Now I will give the object reference on that function and then will run my project again. You can see in the video this time my Webview App is running perfectly, not crashing anymore. So I have solved my app crashing problem. You can solve find your app crashing reason and solve this way.

By the way, if you want to know in your app which code is executing, what is happening in your app. you can select Debug from the Logcat. You will be able to see everything there. See you in the next post. Thank you.
