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.
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:
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.
I juts want to know how can I access a certain data from my SD card. How can I browse SD card contents? For example, from my application, I want to open a pdf file from SD card, how am I going to do this? I tried to write this code but it doesn't seem to work. Uri uri = Uri.parse("file:///sdcard/"); Intent intent = new Intent(Intent.ACTION_PICK, uri); startActivity(intent);
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)?
I usually view email with attachments from my pc because I usually lack the time to download the attachment. Today, I had some spare time so I tried to download an attachment. It downloaded fine but when I went to view it, I received a pop-up box to save it to the sd card. After pressing ok, I was told the save was successful but now I can't find it. Aside from pics and videos, how do I access other folders with saved data?
In my android application, I would like to retrieve the birthday field from google.com/contacts, as this field isn't synchronized in the android contacts application. How can I have a read access to google contacts? I saw the Google contacts APIs, did I have to use it? Which one? The Portable version? Or is there a simple way to read these contacts, as Android does when there is a synchronization?
I want my app to access database every hour and read next record from the table then update desctop widget and send notification. I know that there is AlarmManager which I can use to register my Intents but they are deleted when the phone is turned off or rebooted. Is there any other android class/service that I would update my application continuously even when I reboot my phone?
Dear Android geeks, I am new to android development, and i want to develop an app in which u can set some data and location in google map and at a later time we can retrieve it also. Please help me out with it I am not able to set data in maps.
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.
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?
I want to read MMS data i have seen the part table in the mmssms.db where the mms entries stored i am using cursor to and i want to know the appropriate URI like i am using "content://mms-sms/conversations" and the Column names of "Address"(Sent to), "Text" or "Subject" and "Data" column name of image.

So, I have Itunes Agent and when I had the 2 GB card it synced perfectly, no problem. So I get the 16GB card and my computer suddenly doesn't even 'recognize' that there's a device connected. WTF, So, not very computer savvy, I figure it must be the computer because the card seems fine in the phone?
as seen above in the desire forum, im having this issue. it just occurred today.i have a 16GB Sandisk, stock and unrooted. i move about 4 apps to SD card (out of the 30 ish apps i have, only 4 were available to be moved to SD).Micro SD card mounted as Read Only? - HTC EVO? 4G (Sprint) - Android Forums - HTC Community.seems all of us having this issue posted today or within a day or so.. so it seems like it may be Froyo related.
After the update last night to 2.1. I can only read the files on the sd card. Deleting is not possible. Did a format with the phone and copied all over on the card, no luck. Putting the card in the PC. I can do everything with the files, copie, delete and so on. Then did a format with the pc fat32 and copied all back, again on the phone only read only.
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.
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?
