Android :: Read Mail Intent With Access To Email Data?

Nov 17, 2010

Android documents starting the email intent for sending emails with Intent.ACTION_SEND. Is there an intent which directs the user to reading his email, or which launches the default email application? The application that launches the "read mail" intent would get no access to the email data.

Android :: Write / Read Access To SD Card In Manifest File

Mar 1, 2010

Is there a right associated with write/read access to the sd card that needs to be set in the manifest.xml file? I'm currently trying to write to the sd card using a standard FileOutputStream here:

FileOutputStream out = new FileOutputStream("/ sdcard/images/"+imageName);
bmp.compress(Bitmap.CompressFormat.JPEG, 90, out);

But it doesn't seem to be working. It just says the location isn't found, which can happen if there are no permissions to read/write to the location.

Android :: Read Data That Been Separately Copied To Sd Card Without Having Root Permissions?

May 4, 2010

I am developing an application that needs to access data on the sd card. When I run on my development device (an odroid with Android 2.1) I have root access and can construct the path using:

CODE:..........................

However, when I install this on a phone (2.1) where I do not have root access I get files == null. I assume this is because I do not have the right permissions to read the data from the sd card. I also get files == null when just trying to list files on /sdcard. So the same applies without my constructed path.

Also, this app is not intended to be distributed through the app store and is needs to use data copied separately to the sd card so this is a real use-case. It is too much data to put in res/raw (I have tried, it did not work).

I have also tried adding: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

To the manifest, even though I only want to read the sd card, but it did not help. I have not found a permission type for reading the storage.

General :: Unable To Access Application Data From SD Card After Factory Reset

Mar 2, 2013

Yesterday I tried to install a custom ROM on my device (HTC Evo 3D GSM Europe) for the first time and it took close to 12 hours to get it from ICS 4.0.4 to ICS 4.0.3 (when my intention was actually JB 4.2). Let's just say that forgot to backup his Shipped ROM, then installed JB, was incompatible with the boot loader, tried desperately to find a compatible shipped RUU that worked with the CID, spent countless hours searching in xda-developers and then finally settled for a custom ICS ROM until some time in the future.

Now on to my problem. Prior to my Factory Reset, I had moved all applications to the SD card. A simple look-over in the file system indicates all the data is still there, but reinstalling the applications and even moving them back to the SD card doesn't seem to give them access to the prior data (saved games, stored profiles, lists and anything else I might have done). It's as if the app has been installed for the first time.

Is there any way to "link" the data back to the apps (after yesterday's endeavor I ended up with a rooted phone, at least)?

Android :: How To Read CID Of SD Card? (MMC)

Aug 8, 2009

How can I read the CID (Card Identification register) of an SD card with Java or C-Code in an Android phone? I tried "cat /sys/class/mmc_host/mmc1/mmc1:*/cid" but at least on the Samsung I7500 Galaxy it does not return the CID of the SD card because it is always the same number with different SD cards.

HTC Hero :: PC Won't Read SD Card

Aug 15, 2009

My PC will only read the microSD card (2GB one supplied with the phone) installed in my HTC Hero if I remove the card from the phone and plug it directly into the computer.

If I simply attach the USB cable, a 'D:' drive appears, but I get the error message "Please insert a disk into drive D".

I used the card as is, and did not 'format' it first; should I have done this?

Android :: Read Data From USB Attachment

Feb 24, 2010

Is there anyway to read data from an attachment through the USB port on an Android device? In particular, an EKG. Most the work can be done by the hardware of the device to simplify the output to a single number, a voltage reading. If its not possible, what about modifying an accessory that can already communicate with an android device? Thinking of devices that attach to android phones, what about sending the data as an audio signal to be read as the microphone from a headset and then analyzing the audio signal to convert it to a number that can be used to display a value. how to make this work?

HTC EVO 4G :: Sd Card Is Mounted As Read Only / Got Error

Aug 1, 2010

Well I have a problem and need some help. So for no apparent reason I started getting an error with my sd card last night. At the notification bar, it says the sd card is mounted as read only. The phone gives me the option to try to fix it. It tries without success. I have tried resetting the phone and fidgeting with the card...both with no success. Its frustrating cause I can't take pictures as a result and all I see is that error message! Its an eyesore at the top of my screen.

General :: Can't Read / Write SD Card

Oct 23, 2012

I did a backup using Titanium Backup and Go Backup and after wiping my Motorola Defy, tried to restore apps, contacts etc. The problems I encountered were:

1) Go Backup can't recognize backup directory on SD card for some reason.
2) Can't move apps to SD. An error occurs: "Move Application: Failed to move application. There is not enough storage left." Needless to say, I have more than enough storage.

This is was I encountered by far, although I believe these are just a small part of the symptoms for a single problem.
Maybe its because there are no permissions, or moving apps is impossible because of an existing app files on the SD card.

What is the actual cause for this? Or is there a tool to fix the permissions on the Defy?
