Intent intent = new Intent(); intent.setAction(android.content.Intent.ACTION_VIEW); File file = new File(filepath+filename); intent.setDataAndType(Uri.fromFile(file), "application/pdf"); try { startActivity(intent); } catch (ActivityNotFoundException e) {

How would i be able to get the mimeType from an application. I am working on an application which filters certain installed applications based on the mimeType.
View 5 Replies View Relatedis there an easy way (api) to do this?
View 6 Replies View RelatedI'd like to query the contacts and create an RDF model (FOAF to be exact) from the data received. Therefore it would be necessary to know what kind of data I'm dealing with.
I'll need the following information about each contact: name, phone number(s), email address(es), IM ID(s) + corresponding IM service.
I thought that the best way to get this information was via the ContactsContract.Data table. So my query looks like this:
code:...........
Cursor contactsTable = managedQuery(contactsURI, projection, where, whereArgs, null); </code>
(I need the DATA_VERSION to know if updating the model is necessary.)
Now I'd like to go through the table and add properties to my model for each entry. Therefore I'd need to know if the row I'm currently reading contains a name, an email address, a phone number or an IM ID (it would be best if I could also get information about the IM service the ID belongs to).
Is it possible to get the CONTENT_ITEM_TYPE or anything like that? Or should I perform a single query for each type and then connect the information via the CONTACT_ID?
I try and open up a new activity, pointing to the market, with the following code:

It works fine on the device, but the Emulator throws an Exception:

I'm not sure if this is just an emulator thing, or whether this could replicate on a real device?
I have a folder on sd-card in which I keep photos edited in my application. Im trying to force deafult android image viewer to see all pictured in that folder. Unfortunately I am able to see only one picture. The "next" and "previous" arrows are disabled.
The code i use to see only one picture:

How to activate the browsing option? how to call the intent so that every picture in that folder would be visible?
I have an image file on my sdcard and the path to the file is: /sdcard/apps/MyPath/1249487966270.png
When a user clicks a button on my application I want to display this image to the user. Inside of the click listener I'm using the following code:

The button click event happens, the activity is started and then it is ignored. Nothing appears!
Watching the log through DDMS I see the following entries:

I would like to run an ACTION_VIEW with memory data.
The first solution is to write data in a file on sdcard but ... it does not seem so efficient. I was thinking to implement my own content provider, but as far as I understand I need to return an ParcelFileDescriptor. I found a MemoryFile implementation in SDK, however I don't know how to get a ParcelFileDescriptor for a MemoryFile.
I have an application that needs to have a user visit a web page to authorize it. After spending time in the Browser the user should return the my application.
Currently, I'm launching the Browser with:
CODE:................
After using the browser, I can go back home and launch my application, which stacks a new Activity on top of the previous stack of Activities that were being used in the application. For example. If the user launches the app, they have Activity A in the stack. From there we navigate to Activity B which then launches the Browser. Then, the next time we enter the app, we launch Activity A, which is pushed onto the stack that already contains an A and B.
My question is then, how can I just go back to the previous stack? Basically, do I have to create a new Activity? Is there a better way to launch the Browser, and then come back to my application?
Also, I've been using the Intent.FLAG_ACTIVITY_NEW_TASK when I start the Browser activity so that my app stays running.
I have an application that sends messages to a specified contact. Right now I use
CODE:..............
To send messages, and it works great on the emulator and on my N1. I got complaints from users with HTC incredible that they get force close from android.mms application when they use it. I did more digging and I see there are many ways for sending messages.
For example
CODE:........
And also
CODE:....................
They all seem to work exactly the same on the emulator and on my device, and I could not find anything official about the correct, generally supported way.
I am using PackageManager class to retrive the information of the installed application on the device. But I didnt get any way to retrive the application Size on the device. Can any one help me out in getting how to achive this.

View 4 Replies View RelatedI just rebuilt an application to use some new assets, and now I get this message on my phone when I try to install it: "Application not installed" "UnitTests could not be installed on this phone" Anyone know what's going on? I've checked and I've definitely got "Unknown sources" ticked on the application settings. This is just a self signed application to run my unit tests on an actual phone (the emulator doesn't cut it for real testing). I tried creating a new keystore, and they didn't help. What on earth? The only thing I can think of that I've done recently is accept a google security update.If they've silently done some other updates that prevent self signed applications running, I'm severely upset.

View 3 Replies View RelatedI was getting the error "Application not installed", when I tried to download a simple application(developed by me).
Here is the process I followed:
1. I created a simple application 2. Using eclipse, I exported it as an unsigned application package. (Android Tools/Export as an unsigned application package). This resulted in a .apk file. 3. Using keytool, I generated a keystore, with which I signed the application using jarsigner. 4. Using zipalign tool, I aligned the package. 5. I linked the apk file to my website, where I can download the app.
I verified all the above processes.
When I download the app, and tried to install, it says "Application not installed".
I am not knowing what resulted in this error.
How many activities do you have? Do more than one of them declare themselves as launchable like you can see below?

View 4 Replies View RelatedI have big files to integrate into my application (videos), and thus for not not that my application occupies all the internal memory of the telephones, I saw that it was possible with Froyo to install the applications on the SD card.
I thus have to test this solution and my application settles down well on the SD card, the only problem it is that the system installs all the same my files videos (which are placed in the file /raw) on the internal memory of the telephone. Thus my question it is where to place my videos or where to make so that these also settle down on the SD carde ?
I created an android application and uploaded in my website.Is it possible to check from the web whether this application is installed in the device when someone is trying to download the application?

We have an app that we have tested successfully across 10 different devices on 4 different networks without a problem. However, our app will not work on ANY Nexus One devices, tested across 4 different carriers. The work flow is like this:
1. Via the browser, visit a URL to download the apk file OTA.
2. Install app. App shows up on the device.
3. Click the icon to run the app. An error occurs saying "Application is not installed on your phone"
At this point, we can see the app is trying to run. LogCat shows the following interesting bit:
