Hi Everyone! Hope you all are doing great.Today we are going to learn how to update your existing app in google play store and what changes needs to make in app with android studio.

First Open the Android Studio in your pc.Then click on Open project and select your project to open.

After opening your project , your project will Sync.Then you do change what you need to Change.I will update my Website Url , So I will paste my website url to the previous url.

My Changes are done, Now I will open the gradle.build file. And you can check the dependencies , whether any dependency has any update or not.If they have update, you give update to them. You can follow the video .

Now we will update the Version Code and Version name. 

For updating the version code, you should check your last release app version code in Google play store. And in the app you need to increase the version code number. Your app version code should greater than google play store app version code.Otherwise google play store will not allow you to update your app.

I see my most recent release app version was 8 and version code 8.1, So I will increase one number and will write it version code 9 and version name 9.1.

Now click on Sync Now.

Ok So all changes are done,Now I will run my App on the Emulator for checking whether my app is working is not.

You can see my app is running successfully.

Now I will generate the signed app for updating in google play store.For doing that, click on “Build” from above option and click on Generate Signed App/Bundle. You can create whether Bundle or apk, both are ok. I will select apk. 

Then give Keystore password, Key Alias and Key Password. These password should matched with the existing app in the play store. These password you have given when you generate this app first time. Now click on Release and Finish.

That’s it, your app will generate successfully. You can see my apk generated successfully. In the next video I will show you “How to update your app in Google play store”.

 Hi Everyone!! Today We will fix the issue of "could not parse the android application module's gradle config. Resolve gradle build issue and/or resync".  

As we know if we want to connect Firebase with our Android Studio project, we can do it by manually add or can add by Android Studio Assistant Tools. 

So today we will try to add firebase with our Android studio project by firebase Assistant. For doing that first we need to go the "Tools" from upper bar. Then click on "Firebase" . After that in the right sight you will see the android studio Firebase Assistant has opened. And you will get the "Authentication" option, Click on that. After that you will see "Email and Password Authentication" ,  click on that.  

Now you will get the step of connecting Firebase with your Android studio project. First we will complete the first step which is Connect to Firebase. You can see in the video I am getting error after click on Connect to firebase. The Error is showing " Could not parse the android application module's Gradle config. Resolve gradle build issue and/or resync, So let's check what issue we have in Gradle file. 

As we can see our build screen showing that our build tool 31.0.0 is missing. So, Lets check and install the build tool 31.0.0 version. For checking that, click on Project Structure icon, 

then you will get the Android SDK window, there you will see all the SDK version tool, from there you can install any SDK in your project  or you can easily uninstall also.

 Hi Everyone, Welcome to our mobile app developer training. As we are Converting our website to apk, in the previous tutorial we have learned How to Enable Video, Image and File Upload in Android Webview App.

And we also have learned separately How to Upload files in Android Webview App and How to Download the files in the android webview app. 

Now we will combine uploading files and downloading files code together and will implement them in one Webview app project. 

First of all, you need to add 3 permission for "access camera, write in external storage and Internet" in your AndroidManifest.xml file. 

Then, we need to take some variables, such as:

After that, we will move to the "onCreate" method, and in the "WebChromeClient" function we will write the "onShowFileChooser" function.

Now we will write code for Downloading any files in Android Webview App. First, we will write a function for file saving permission to your device.

And then we will write code for allowing download file in the Webview app.

We have finished the coding within the onCreate method, Now we will write several functions outside of the onCreate method.

That's it, we have finished coding for Uploading and downloading files in the Android webview app. Let's run the project and test.

As you can see in the above picture, Downloading any file and uploading any type of file in Webview App is working perfectly. See you in the next tutorial.

 Hi Mobile App Developers, In the previous video we have learned that How to Enable File upload in Android Webview app. And I told in the last video that we will learn today how to upload multiple types of files together in the Android webview app.

As we saw in the last tutorial, we are able to upload any type of file such as Audio, Video, Txt, XL, Zip, PPT, etc. But we saw that we can only select one file and upload one file at a time,  So today we will learn How to select multiple files and upload multiple files together in the Android Webview app.

We will continue with the last tutorial code, If you have not followed that tutorial yet, first follow that tutorial, then continue this tutorial. Let's Start.

First, we will take a boolean variable, we will name it multiple_files, and the value we will store is "Yes".

Now we will move to the "onShowFileChooser" function, in that function you will find we have written code for file selection, now we will write code there for multiple file selection.

These codes will help you to select multiple files at a time in the Android webview app. Now let's see what will be the full code within the "onShowFileChooser" function.

Just need to add these line of code in "onShowFileChooser" function , and all the other code of Upload file in Webview (my last tutorial) are same such as "onActivityResult", "onConfigurationChanged", "file_permission" , "create_image()", "create_video()".  Now let's run the project and check whether Multiple file selections and multiple file uploading in the Android webview app are working or not.

As you can see in the above picture, multiple file uploading working perfectly. This way you can convert your website easily. It works like website to apk converter. 

In the next, I will show you How to Enable Upload and Download in Android Webview App.

 Hi, Everyone! I have got many requests and comment about "File upload not working in android webview app", also "can not uploading pdf or video file in android webview app", you all have requested me to help you for solving the problem.

Today I will solve all the problems about "How to enable or support file uploading in android webview app", "How to allow any type file uploading such as pdf, ppt, audio, video, image, txt"? anything you will be able to upload in your webview android apps. Just follow my tutorial from beginning to end. In the previous video, I have showed you How to Enable Download in Android Webview App.

So, Let's start, First of all, you need to add 3 permission for "access camera, write in external storage and Internet" in your AndroidManifest.xml file. 

After adding the permission, now need to move to the "MainActivity.java" file, now let's take 5 variable, which are: 

Let's demonstrate, why we have taken these variable,  we have taken a private static string file called "file_type", this is for storing file type we want to upload in our webview app, such as pdf, ppt, pptx, ppt, audio, video, image, doc, zip, RTF, txt, etc. 

As we want to allow all types of these files uploading in our android webview app, so we have defined file_type = "*/*". "*/*" this means it will allow all types of file uploading in the android webview app.

cam_file_data: This String variable "cam_file_data"  for storing camera file information.

ValueCallback<Uri> file_data: We have taken the "ValueCallback" variable, we have named it "file_data", this will store data after selecting the file.

ValueCallback<Uri[]> file_path: Another "ValueCallback" variable, we named it file_path, this will store file location.

Now let's move to the "onCreate" method, and will write a function method called onShowFileChooser in our setWebChromeClient, and all the necessary code will write on this function,  See the  Below Code:

Now we will write a function "onActivityResult"  for selecting the file from the Camera or SD card in android webview app.  This function will be outside of "onCreate" method. See the  Below Code:

Now we will write function called "onConfigurationChanged"

Now we will write a function "file_permission" for checking and asking for required file permissions.

We have taken a variable "photoFile"  in the "onActivityResult" function, there we have stored a function called "create_image()". Now we will create that function. 

Now we will write function for video file

We have finished the coding. Now Let's run our project and check whether any type of file is uploading in our android webview app or not.
