Share pdf file or Image file using kotlin code example

Share pdf file or Image file using various other application in android Kotlin with code 


Starting from Android version  7.0 (API level 24) and higher, the file:// URI scheme is no longer supported for sharing files between apps due to security reasons. Instead, we use  a FileProvider to share files with other apps.

Otherwise we got error:

FATAL EXCEPTION: main

Process: com.nipa.xlsheetcreate, PID: 11878

android.os.FileUriExposedException: file:///storage/emulated/0/createXLSheet/06-15-23-14-28_document.pdf exposed beyond app through ClipData.Item.getUri()

at android.os.StrictMode.onFileUriExposed(StrictMode.java:2141)

For solving error we using provider , let’s check below code for sharing a file

 

Add in manifest file for permission:

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

 

Create a xml file in : res/xml/ provider_paths.xml

Add code below:

<?xml version="1.0" encoding="utf-8"?>

<paths>

    <external-path name="external_files" path="."/>

</paths>
Then in manifest file write below code:
<application
…>
<provider

    android:name="androidx.core.content.FileProvider"

    android:authorities="${applicationId}.provider"

    android:exported="false"

    android:grantUriPermissions="true">

    <meta-data

        android:name="android.support.FILE_PROVIDER_PATHS"

        android:resource="@xml/provider_paths" />

</provider>
 
 
Then Activity page write below function and share file :

private fun sharePDFFile(file:File ) {

     

    val URI = FileProvider.getUriForFile(

        this@MainActivity,

        BuildConfig.APPLICATION_ID + ".provider",

        file

    )

    val intent = Intent(Intent.ACTION_SEND)

    intent.type = "application/pdf"

    intent.putExtra(Intent.EXTRA_STREAM, URI)

    intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION

    startActivity(Intent.createChooser(intent, "Share PDF"))

}

Padding to number at the begging using kotlin code

-
Padding to number at the begging using Koltin code  Sometimes we need to show number with leading zero of integer like Entry Number: 000005 So we need padding for that integer. In Kotlin we do it various way: -   The padStart() function in Kotlin is a string extension function that pads the beginning  of a string with a specified character or sequence of characters until the desired length  is reached.   The padStart() function takes two parameters:   length: The desired length of the resulting string after padding, it is Int type parameter. padChar: The character used for padding. padStart ( 5 , '0' ) here 5 is length of resulting string and ‘0’ is padded when create result string.   Example:   val yourString = "hello" val paddedResultString = yourString . padStart ( 10 , '*' ) println ( paddedResultString ) // Output String : "*****hello"   For Integer Variable: fun padBegining (intData: Int ): String {     return ...
