Android :: Possible To Attach File To Email Without Writing To SD?
Dec 2, 2009
My application stores data locally in the native SQLite db, and I want to allow users to export this data by emailing themself a .csv file. In order to do this I'm generating the .csv from the database and writing it to the SD card, then attaching it to an email:String Builder csv = generateFile();writeFile(csv.toString(),"file.csv");Intent email = new Intent(android.content.Intent.ACTION_SEND);email.setType ("application /octet -stream"); email.putExtra(android.content.Intent. EXTRA_ STREAM, Uri.parse ("file://sdcard/file.csv")); Which all works great. What I'm wondering, though, is if it is possible to skip the step of writing to SD first, and directly attach the data.

By default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user).I am able to see the file "/data/data/package_name/files/ in file explore in DDMS, but when i attached the above file URI using imageUri in email , then i saw that attached file is of 0kb.i have used the default email APIs of Android.Can anyone suggest me ,how to attach a file in email that is private to the application?although i am successful able to save the file in SD card and attaching the file from SD card , this is working fine.But if SD card is not available and saving the file to the internal storage , then how can i attach them in email.

I am trying to launch an Intent to send an email. All of that works, but when I try to actually send the email a couple 'weird' things happen.So if I launch using the Gmail menu context It shows the attachment, lets me type who the email is to, and edit the body & subject. No big deal. I hit send, and it sends. The only thing is the attachment does NOT get sent.I figured, why not try it w/ the Email menu context (for my backup email account on my phone). It shows the attachment, but no text at all in the body or subject. When I send it, the attachment sends correctly. That would lead me to believe something is quite wrong. Do I need a new permission in the Manifest launch an intent to send email w/ attachment? What am I doing wrong?

The only thing that seems to attach in a text message are pics and music files. I am probably making it way too difficult, i tend to do that .

I have a programmatically generated image that I want to send as an attachment via the ACTION_SEND and EXTRA_STREAM method. But how do i do this? My first attempt (writing to my context.getCacheDir() based file path) appeared to work in the Gmail preview (no image preview, but attached file name and icon was visible), but the attachment never arrived on the recipient side. I guess this has something to do with permissions on the generated file, but how to avoid this? Do I need to set more permissive settings on these generated files (so that the Gmail activity can access)? Is that even possible for the app's cache folder?
Is there another file location that would be more suitable to write my files to? I considered the downloads folder, but think it would be an awkward location for something that only needs to exist until it has been emailed. I have even tried encoding my image purely in a data:image/png;base64,ABCD... style URI. This, too, showed up in Gmail preview (attachment icon, but no file name), but did not result in a recipient-side attachment. Has anyone been able to attach a one-shot generated image to an email intent by any means? What options may I have overlooked?

I can send picture MMS on my Fascinate but everytime I want to attach a file and choose camera (take the picture right now) it never sends the picture I take, it sends a picture I took about 3 months ago, that is not even on my phone. I can choose attach and then picture to pick one from my phone and it works great, but when I try to attach then choose camera, it just sends one that I sent 3 months ago and I can not change it.

I tried to create byte array blocks from file whil the process was still using the file for writing. Actually I am storing video into file and I would like to create chunks from the same file while recording. The following method was supposed to read blocks of bytes from file:
private byte[] getBytesFromFile(File file) throws IOException{
InputStream is = new FileInputStream(file);
long length = file.length(); int numRead = 0;
byte[] bytes = new byte[(int)length - mReadOffset];
numRead = is.read(bytes, mReadOffset, bytes.length - mReadOffset);
if(numRead != (bytes.length - mReadOffset)){
throw new IOException("Could not completely read file " + file.getName());
} mReadOffset += numRead; is.close(); return bytes;
}
But the problem is that all array elements are set to 0 and I guess it is because the writing process locks the file. Any other way to create file chunks while writing into file.

I am writing an android application for sending email which launches the default mail application of android and asks to allow sending mail or not.
I want to know the type of Exceptions that are expected to throw in this case.
I have gone through Developer guide and some other Android PDFs ,I am finding only base class Exception.
I want to know are there ant other exceptions that will be thrown other that exception, which we need to handle in our program.

I have an Android app that saves a text file directly onto the phone, in the app's install directory. I need to allow the user to create a new email, attaching this saved text file. When I start the intent to send the email, everything shows up in Gmail correctly, but the attachment does not get sent. All of my searches on stack overflow seem to only deal with attaching an image file from the SD card. Below is the code that I used. Please let me know if I have done something incorrectly.
File myFile = new File(getFilesDir() + "/" + "someFile.txt");
FileOutputStream stream = null;
if( file != null )
steam = openFileOutput("someFile.txt", Context.MODE_WORLD_READABLE);
stream.write(some_data);
Uri uri = Uri.fromFile(myFile);
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
sendIntent.putExtra(Intent.EXTRA_TEXT, email_text);
sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
file.close();
startActivity(Intent.createChooser(sendIntent, "Email:"));
I've also tried sendIntent.setType("application/octet-stream"); but that didn't make a difference. I'm at a loss for why the file doesn't attach and get sent.

When I attempt to attach something to an email (using Gmail) I only get the option to attach photos. Can anyone else attach video or is it just me? However, when texting I get the option to attach video or photo.

Are any <uses-permission> clauses needed in the manifest for: 1. Writing to a file using the Activity.openFileOutput() mechanism; 2. Writing to the SD card using FileOutputStreams; 3. Sending email using the Activity.startActivity( Intent.create Chooser (...)) mechanism
http://developer.android.com/guide/topics/security/security.html and didn't see anything that seemed relevant. My app works on my ADP1 without any <uses-permission> clauses when installed with "adb install xyz.apk" but I was worried that it may have problems on a "real" consumer device.

I'm writing a simple budget app for myself, and I'm having trouble figuring out how to write to internal storage. I don't seem to be writing to the file properly and I can't find any more in depth examples than the Data Storage article on developer.android.com. Basically, I'm trying to write a test float to the MyBalance file, then read it into balance. In my actual code I use try/catch statements around the file in/out operations but I skipped them to make the code more readable.
float test = 55; float balance; byte[] buffer = null;
FileOutputStream fos = openFileOutput( "MyBalance", Context.MODE_PRIVATE );
fos.write(Float.floatToRawIntBits(balance));
fis.read(buffer); //null pointer
ByteBuffer b = ByteBuffer.wrap(buffer);
balance=b.getFloat();
That's the gist of it, anyone see what I'm doing wrong? I went ahead and converted to/from String but I still don't think the file is being created. I have an if statement that reads from it if it exists in onResume() and it isn't being run. Lemme post some of my code. Here's how I'm writing the file, (setbal is an EditText and balanceview is a TextView):
balance = Float.valueOf(setbal.getText().toString());
balanceview.setText(setbal.getText());
balstring = String.valueOf(balance);
for (int i = 0; i < balstring.length(); ++i)
try { fos.write((byte)balstring.charAt(i));
} catch (IOException e) { e.printStackTrace();
}
I check if the file exists in onResume() like so:
File file = new File("data/data/com.v1nsai.mibudget/balance.txt");
Is that where an internal file for that context would be stored?

I am developing an application that read data from sensors and write those data to an XML file when you press a key. i have 2 activity one for button and another is an Activity who implements sensorEventListener. the problem is my main activity is button and couldn't get data from event listener activity. i think the listener activity is not active but when i create an intent and start activity with that intent the program stop working. the button is able to create XML file solely.so how could i read sensor data from sensors,and how to send them to XML file when the button got clicks.
