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.

How to Fix could not parse the android application module's Gradle config || Add Firebase with Android Studio Project

November 06, 2021 0 Comments

 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.





As you can see in above image, my project already has installed SDK build tool 31.0.0,  now click on Show package details from bottom, now you will be able to see which version is installed in your project. As we see our project already has build tool 31.0.0 installed, let's try to build the project again.


Now you can see it's showing the error of "Installed Build Tools revision 31.0.0 is corrupted", So we need to solve this problem now.

For solving this, first click on project structure.





After click on "Project structure" , will open a window, in that window in the "Modules" section, you will see Compile SDK Version, there you need to select the version 30.0.0 and in the Build Tools Version, select the version 30.0.1 or 30.0.2 or 30.0.3 all are ok. Then click on OK. 

After that, your project will automatically start to sync, After syncing done, we will try to build our project and will check whether we solved our problem or not.

As you can see, our project successfully build, we have solved Installed Build Tools revision 31.0.0 is corrupted. Remove and install again using the SDK Manager"

Now let's check whether our main problem has solved or not. Which was "could not parse the android application module's gradle config. Resolve gradle build issue and/or resync" .

Let's try to connect Firebase again, now you will see, once you click on Connect to Firebese, it will automatically open your browser window and will go to Firebase console, you need to create a new project on firebase, or you can select your existing firebase project, then they will ask several permission, just click on  Continue, and at the last the Add Firebase this button will appear. click on that.  After that your Firebase project will ready and you will get the below image. 



Click on Connect.






As you can see our Android studio project is connected with Firebase successfully. So we have solved both problem of "could not parse the android application module's gradle config. Resolve gradle build issue and/or resync" and "Installed Build Tools revision 31.0.0 is corrupted. Remove and install again using the SDK Manager" successfully.


That's it.

 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. 


Code:

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

Code:


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


Code:


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.


Code:


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

Code:


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


Code:


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.

How to upload multiple files in webview android app | Webview App Development Series Part 18

July 03, 2021 1 Comments

 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".



Code:


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.


Code:


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.

Code:


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.

How to Enable Video, Image and File Upload in Android Webview App | Webview App Development Series Part 16

June 27, 2021 8 Comments

 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. 


Code:


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

Code:


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:


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:


Code:


Now we will write function called "onConfigurationChanged"

Code:


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


Code:


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. 


Code:


Now we will write function for video file

Code:


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.
