If your targetSdkVersion is 24 or higher, we have to use FileProvider class to give access to the particular file or folder to make them accessible for other apps. We create our own class inheriting FileProvider in order to make sure our FileProvider doesn't conflict with FileProviders declared in imported dependencies as described here.

Steps to replace file:// uri with content:// uri:

• add a class extending FileProvider

  public class GenericFileProvider extends FileProvider {
  
  }
  

• add a FileProvider tag in AndroidManifest.xml under tag. Specify an unique authority for the android:authorities attribute to avoid conflicts, imported dependencies might specify ${applicationId}.provider and other commonly used authorities.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    <application
        ...
        <provider
            android:name=".GenericFileProvider"
            android:authorities="${applicationId}.my.package.name.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths"/>
        </provider>
    </application>
</manifest>

• then create a provider_paths.xml file in xml folder under res folder. Folder may be needed to create if it doesn't exist. The content of the file is shown below. It describes that we would like to share access to the External Storage at root folder (path=".") with the name external_files.

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

• The final step is to change the line of code below in

  Use the below mentioned code to open excel file :

  File file = new File(Environment.getExternalStorageDirectory()+ "/filepath/" + filename);
  Intent intent = new Intent(Intent.ACTION_VIEW);
  intent.setDataAndType(Uri.fromFile(file),"application/vnd.ms-excel");
  startActivity(intent);
  

• Edit: If using an intent to make the system open your file, you may need to add the following line of code:

  intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
  

Hope this will help...:)

Please refer, full code and solution has been explained here.

If your targetSdkVersion is 24 or higher, you can not use file: Uri values in Intents on Android 7.0+ devices.

Your choices are:

1. Drop your targetSdkVersion to 23 or lower, or

2. Put your content on internal storage, then use FileProvider to make it available selectively to other apps

For example:

Intent i=new Intent(Intent.ACTION_VIEW, FileProvider.getUriForFile(this, AUTHORITY, f));

i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(i);
