We are trying to access bytes in non-sequential order from a 'content:' URI that we receive in the intent from other applications. Is there a way to do this, without buffering the bytes within the application?
We found a discussion about the same from 2008 at: http://groups.google.com/group/android-developers/msg/49a1b7d651d4707e Is it possible now?

I don't know how to get random access to a raw ressource. It is easy to get a FileInputStream from a raw ressource, what about RandomAccessFile?
View 2 Replies View RelatedSo I just got my Nexus One (like literally a few hours ago) and yay everything is nice (well not everything - for some reason I can't download apps from the market). Anyways, I figure, let's see how this thing is for reading pdfs.
I mounted it as a drive via usb. Created a docs directory, and place a pdf book in it.
Ok...Now how do I open that file?
Again we're talking Nexus One

I want to access the messages stored in in box through my android project. I have tried the method of forming URI for sms (content://sms/ in box) and then querying it for various parameters. But I cannot find any documentation for reading in box sms in the standard Android Develop Docs. It was mentioned at various websites that this content has been removed from the standard sdk. The application may not support higher version of android.
View 2 Replies View RelatedI am trying to play a ringtone that is specified as the Default system ringtone. Unfortunately when i get the actual URI I get the above (content://drm/audio/2) and then when I try to play it, I hear the fallback ringtone - the one that you'd hear if the default was unavailable.
Ringtones appear to get this URI when downloaded through sites such as Myxer and the like.
Now it seems that when the default ringtone is on the SD card under a folder called 'ringtones' I do not run into this problem.
I have tried to add the line:
<uses-permission android:name="android.permission.ACCESS_DRM" />
...to the manifest but that doesn't seem to work either.
If anyone has an idea as how I would be able to play this ringtone, I would be eternally grateful! I have been researching this and I can't seem to find anywhere any documentation on how to do this.
is there an easy way to limit my content provider access to only one or more packages I don't want other packages to access my data.
I looked at grantUriPermission but its not straight forward and it doesn't work.

Is it possible to access the X-Mms-Content-Location attribute of a message from a MMS message programatically, using the Android SDK?
This is one example of the error that I am investigating. If I can access that attribute, then I may be able to code an app which repairs it so the message retrieval succeeds.

Just found out that I don't need content providers if I don't need to share data with other applications. But since the examples I've seen all use content providers, I'm not sure how to proceed without them and populate activities with data derived from accessing my application's database directly.
View 2 Replies View RelatedSomeone post the code for accessing .txt file available in my res folder. The code for which can be written in .java file.
View 4 Replies View RelatedI found that if I want to use the searchable options using the search key I have to create a content provider. Content provider is used to share data across applications.
But I do not want to allow access to my content provider (as well as my data) except/outside my own application. I want to use it only for search suggestion. Because my app data is kind of restricted.
Is there any way to implement local search without content provider? OR is is possible to apply restriction so that except my own app no other app can use my content provider?
i have four Question Regarding Android Default Email Program Please help me out to answer the questions respectively
1) How can we access the Device Database ?
2) How can we setup email on Emulator ?
3) Can we read Email Content Through Email Content Provider like ( AttachementProvider.java)
i have found in Git
4) can any one tell me the corret Email URI
i have found the URI that is not working
"content://com.android.email.attachmentprovider"
Is it possible to access the content resolver methods in a class extending from AppWidgetProvider class? Have been trying to do it with no luck so far.
View 3 Replies View RelatedI understand, at least on paper, the basic difference between the Content Provider and just directly accessing the SQLiteDatabase. I have a functioning prototype for my application, and currently it is just directly hitting the database. I don't really have any experience using the Content Provider pattern, but I have found out that I will need to share some data with another application.
I will only be sharing about 2 out of a dozen or so tables, so I was wondering if I should be just completely redoing the data layer to follow the Content Provider pattern, or just expose only those tables via a Content Provider for the sake of the other application and still directly access the database in the primary application.
One of the issues I ran into with my prototype was that I have some fairly complex transactions, and the code I wrote to get that working is not designed particularly well and isn't reusable at all. As I add more functionality to this app, I'm going to need a better designed data access layer, before I set off writing my own, does anyone know of any good resources with design patterns for this type of thing already? Also, if I need to go the Content Provider route, am I going to have solid control over the database transactions?
I am trying to login in a website via HTTP post and then via HTTP get download a json file (.do file with json content). This json file url contains a group of parameters that I already sent on the url. Although, I can successfully login I cannot access the content from the json file - I'm downloading the html code of the site - i have already tried for an image or a css and it works.The code goes like this:
Code:
HttpClient client = new DefaultHttpClient();
HttpPost req_post = new HttpPost(url_post);

how to ensure I can access all my APPs and Contact details when using a travel SIM in another country.
I live in AUS and will travel to SPAIN and ITALY, I will use a travel SIM purchased locally there (to keep costs down). Will my APPS still be visible on the phone and will they work? - ie will they still recognise me and have all my data, login details and preferences readily available.
If not, how should I prepare my phone (data card or whatever) so as to ensure I can get access to my APPS working correctly after I have inserted the new SIM. FYI, the phone is a Samsung Galaxy S2 running jellybean.
I've had my Incredible since 4/28, and everything has been working smoothly up until about last Thursday night when it just restarted out of the blue while I was listening to music. Then right after it booted up, it restarted again, then again about seven more times. I got fed up and took out the SD card and it seemed to stop after that, so I haven't put the SD card back in since then.
Just now, Wednesday, about a week later, I was browsing around on the internet and all of a sudden, it restarted, and then again, and again, and again. I've read that it is because of poor signal strength or something like that so I had just enough time to put it in airplane mode before it restarted again.
Side note, that theory about it being caused by poor signal seems to make sense because the first time it happened to me I was out of town in a city that gets very bad coverage with Verizon, and now today when it started happening again was at my house where for some reason I get very bad service with the incredible, my old phone worked perfectly fine in my house but the incredible gets terrible service, and so does my brother's Droid. In fact, about two weeks ago I got my first dropped call on Verizon in about three years, and it was in my house.
So anyways, I decided to put it in airplane mode, and just after I put it in airplane mode it restarted again. Then when it booted back up my Helix Launcher 2 home screen went back to the standard Helix Launcher 2 icons, I go into my messages and everything is gone, my contacts are all gone, everything is gone. I go to the app menu and all my apps are still there, but when I start up an app, all the custom settings are default now. I went into the settings and my accounts are all still there. I click on internet and I get a terms of service agreement, it's as if I am booting it up for the first time, but for some reason my apps and accounts are all still there.
I turn airplane mode off thinking it might have something to do with it not being connected to my google account, and I restart it again and everything is still gone. I don't know what to do, has this happened to anyone before? I feel like there should be a way for me to get this stuff back since my apps are still there and my accounts are still synced, but random things are missing like my contacts and messages etc. This is really starting to get annoying, I have insurance and everything, but I really don't want to exchange it for another one because I've read that other people who have had there phones replaced have still had the same rebooting problem, even after going through multiple replacements.
I am dealing with http post method on Android. I have successfully send simple string pairs using HttpClient and HttpPost class with the NameValuePair as entity. However now I want to send a simple array of bytes[]. Unfortunately the only entities I have found for the HttpPost class are the NameValuePair and FileEntity. However my byte[] is not from a file. Wirting it to a file and then sending by the FileEntity seems to be pointless and stupid. How can I send this array using default HttpClient and HttpPost class?
View 3 Replies View RelatedThis may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?

View 3 Replies View RelatedI am currently sending and receiving SIP messages across a network. When I want to add SDP data to a SIP message I use the SessionDescription object in jrtp.

So I'm wondering is there anyway to convert the byte[] back into a SessionDescription object so I can use the SessionDescription object's methods to parse the data?
