Hey so I save my pdf in external data storage. Eg:
Environment.getExternalStorageDirectory().getPath() + "/file.pdf"
Then, I try to attach it to intent to send:
File attachment = this.getFileStreamPath(fileDirectory + "/" + fileName);
Uri uri = Uri.fromFile(attachment);
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setDataAndType(Uri.parse("mailto:"), "text/plain"); // I have also tried "application/pdf"
emailIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Calc PDF Report");
emailIntent.putExtra(Intent.EXTRA_TEXT, " PDF Report");
emailIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(emailIntent, "Send mail..."));
finish();
and im getting the error:
Caused by: java.lang.IllegalArgumentException: File /storage/emulated/0/file.pdf contains a path separator
I am thinking it is something wrong with were I am saving my file, but can't find any examples that are up-to-date.
To share a file as an email attachment using intent, you need to use a FileProvider.
/**
* Generate file content and returns uri file
*/
public static Uri generateFile(Context context) {
File pdfDirPath = new File(context.getFilesDir(), "pdfs");
pdfDirPath.mkdirs();
File file = new File(pdfDirPath, "attachment.pdf");
file.deleteOnExit();
Uri uri = FileProvider.getUriForFile(context, context.getPackageName() + ".file.provider", file);
FileOutputStream os = null;
try {
Logger.info("Generate file " + file.getAbsolutePath());
os = new FileOutputStream(file);
document.writeTo(os);
document.close();
os.close();
} catch (IOException e) {
e.printStackTrace();
}
return uri;
}
private void share(Context context) {
Uri uri = generateFile(context);
final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_STREAM, uri);
emailIntent.putExtra(EXTRA_SUBJECT, "Send something");
emailIntent.putExtra(Intent.EXTRA_TEXT, "You receive attachment");
emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(emailIntent);
}
In your app add the file provider definition:
AndroidManifest.xml
<application
android:name=".DemaApplication"
android:allowBackup="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.file.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
...
</application>
provider_path.xml
<?xml version="1.0" encoding="utf-8"?>
<paths>
<files-path
name="internal_files"
path="/"/>
<!--<external-path name="external_files" path="./files"/>-->
</paths>
At last but not least, you need to specify the file provider path (where are your files). I hope this helps. Here , the official documentation about how to send email and attachment with intent.
Problem #1: getFileStreamPath()
does not support subdirectories and is not related to external storage , where your file resides.
Problem #2: Uri.fromFile()
will not work on Android 7.0, as your app will crash with a FileUriExposedException
. To fix this and Problem #1, use FileProvider
to set up a content
Uri
that you can use for EXTRA_STREAM
.
Problem #3: ACTION_SEND
does not use a "data" Uri
(ie, your "mailto:"
should not be there).
Problem #4: The MIME type of a PDF is not text/plain
— as your comment notes, use application/pdf
.
Problem #5: getExternalStorageDirectory()
is deprecated on Android 10 and higher, and you will not be able to write files there. Consider using getExternaFilesDir(null)
(called on a Context
) for a better location that works without permissions and on more Android OS versions.

The documentation covers the use of ACTION_SEND
