Android Gmail app-Mail Attachment URI issue

androidgmail

I have to open attachment file from gmail app thru my app.

I get link in pattern like content://gmail-ls/messages/mailid%40gmail.com/4/attachments/0.1/BEST/false

My problem is the link is not unique for each file in the mail client..
One or more file has same Uri.

Is there any way to get the file name or email sent date so that I can come over this issue.

Thanks in advance.

As shown below you can make a local copy of the same attachment and work on that file. Directly you wont be able to access that file which is on the gmail server.

    Uri uri = getIntent().getData();
    if (uri != null) {
    try {
        InputStream attachment = getContentResolver().openInputStream(uri);
        if (attachment == null)
            Log.e("GMAIL ATTACHMENT", "Mail attachment failed to resolve");
        else {

            FileOutputStream tmp = new FileOutputStream(getCacheDir().getPath() + "/temp.myfile");
            byte[] buffer = new byte[1024];
            while (attachment.read(buffer) > 0)
                tmp.write(buffer);
            tmp.close();
            attachment.close();
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    }
    return getCacheDir().getPath() + "/temp.myfile";

Reember to add this to your manifest.

    <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <action android:name="android.intent.action.EDIT" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="*"
                android:mimeType="application/octet-stream"
                android:pathPattern=".*\\.tsconfig" />
            <!-- To handle gmail attachments -->
    </intent-filter>

Android get attached filename from gmail app

Basically, you need to acquire the file system and get a cursor where the info is stored:

import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.MediaStore;
import android.widget.Toast;

public class CheckIt extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Intent theIntent = getIntent();
        String attachmentFileName = "No file name found";
        if (theIntent != null && theIntent.getData() != null) {
            Cursor c = getContentResolver().query(
                theIntent.getData(), null, null, null, null);
            c.moveToFirst();
            final int fileNameColumnId = c.getColumnIndex(
                MediaStore.MediaColumns.DISPLAY_NAME);
            if (fileNameColumnId >= 0)
                attachmentFileName = c.getString(fileNameColumnId);
        }
        Toast.makeText(this, attachmentFileName, Toast.LENGTH_LONG).show();
    }

}

In the cursor returned there is another column - MediaStore.MediaColumns.SIZE. At least that's what I get with GMail on my Desire HD. Just try the above code by operning a mail in GMail and hitting the preview button.

Of course, do not forget to add the following to the activity section in the Manifest.xml (do not drop the android.intent.category.LAUNCHER intent-filter section from the activity otherwise it will not be viewable through the launcher):

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="*/*" /> 
</intent-filter>

Android – get email attachment name in the application

I had the same problem to solve today and ended up finding the solution in another post : Android get attached filename from gmail app The main idea is that the URI you get can be used both for retrieving the file content and for querying to get more info. I made a quick utility function to retrieve the name :

public static String getContentName(ContentResolver resolver, Uri uri){
    Cursor cursor = resolver.query(uri, null, null, null, null);
    cursor.moveToFirst();
    int nameIndex = cursor.getColumnIndex(MediaStore.MediaColumns.DISPLAY_NAME);
    if (nameIndex >= 0) {
        return cursor.getString(nameIndex);
    } else {
        return null;
    }
}

You can use it this way in your activity :

Uri uri = getIntent().getData();
String name = getContentName(getContentResolver(), uri);

That worked for me (retrieving the name of PDF files).
