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"))

}
