Upload excel file to Dropbox or Google Drive?

Question

I'm currently developing an application which creates an excel file(with apache poi) from the sqlite database in android. Everything is working well, except that I can't send the file to another app. I implemented an fileprovider so I other apps can have permission to my file:

AndroidManifest.xml:

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="com.example.ria.masterdetailnoten"
        android:exported="false"
        android:grantUriPermissions="true">

        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"></meta-data>
</provider>

file_paths.xml:

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

ExcelFile.java:

Uri uriFile = FileProvider.getUriForFile(ct, "com.example.ria.masterdetailnoten", backupFile);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setDataAndType(uriFile, "application/vnd.ms-excel");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.createChooser(intent, "Choose");
ct.startActivity(intent);

I know for sure that my file is being created and I can read it again with Apache POI. So the only things which doesn't work is sending the intent to another app.

---

As an example if I choose Google Drive in the intent chooser then following error appears: "Upload failed: request contained no data."

If I open it with the Mailbox App following error appears: "Mailbox could not read the selected file"

I hope you can help me guys, I appreciate your help!

Answer 1

Have you tried using: putExtra(Intent.EXTRA_STREAM, uriFile) instead of: setData(AndType)?

Answer 2

I've managed to work this out with intent.selector = Intent(Intent.ACTION_SEND).apply { data = Uri.parse("file:") }
