I'm currently trying to create an app that will take a picture and then attach that picture to an email that will be going to a pre determined email address.
I have the email working and I have the camera working. I cant seem to get the picture that the camera has taken to add as an attachment. I have the image popping up in the app as a kind of preview image which I have no problem taking out if this is why it wont attach.
When the email is sent a picture has been created but is corrupt and doesn't open. Its as if I'm creating a non existent picture. I think it will be a case of tying the picture taken to the creating attachment part but I have no idea! If anybody could help I would be extremely grateful!
Here is my MainActivity where the email is being created along with the camera:

}
});
Button camera = (Button) findViewById(R.id.button2);
camera.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode== 0 && resultCode == Activity.RESULT_OK){
Bitmap x = (Bitmap) data.getExtras().get("data");
((ImageView)findViewById(R.id.imageView1)).setImageBitmap(x);
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, "title");
values.put(Images.Media.BUCKET_ID, "test");
values.put(Images.Media.DESCRIPTION, "test Image taken");
values.put(Images.Media.MIME_TYPE, "image/png");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
OutputStream outstream;
try {
outstream = getContentResolver().openOutputStream(uri);
x.compress(Bitmap.CompressFormat.JPEG, 70, outstream);
outstream.close();
} catch (FileNotFoundException e) {
//
}catch (IOException e){
//
}
} }
}
I'm hoping its something simple that I'm just not linking them together.
