[android-developers] Sending office 2007/2010 files over bluetooth
I am having problem with send option for Office 2007/2010 files. Mime type i am using is: String mimeType2007 = application/vnd.openxmlformats- officedocument.spreadsheetml.sheet; while it works with2003 mime type String mimeType = application/vnd.ms-excel; INTENT_ACTION=ACTION.SEND What could be the problem with Mime-type here ? Any alternate available or anything to do with Android ? I checked with one of the other open source app installed on my device, it is showing up Bluetooth option for 2007 files. Not sure, if 2003 mime-type is used as quick-fix. But not convinced with this fix. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Queries on Internal Storage - device space
Hello, I explored storing temp/supporting files on Internal storage i.e. SharedPrefs (private to app) and Internal Storage of device. Now, when i try to create a file on Internal Storage, it by default creates and stores file on /data/data/app_home/files/ . My intent was to store a file on some centrally located area i.e some device storage path which is accessible to all applications, and whose file permissions can be restricted using different modes like we have as - MODE_PRIVATE, MODE_WORLD_READ,etc. Quesn is : Is there a way to create a file on such centralized storage location (if it exists on android device) so that it is accessible to multiple apps ?

You said your debugger detaches as soon as your activity gets killed. Check if activity for camera and activity for your usual app runs in separate process. You can check that in DDMS view in eclipse. If thats the case, then you would need to do Debug Configurations - New remote Application - Set up port no on which your process runs, then your debugger wont get detach.

Ok.. But I have seen applications that do not appear with their package name in the list created by intent (dont know what to call this dialog box ) That means there is a way to atleast hide package name.

[android-developers] Re: help for encryption of sd card storage?
Thanks Dianne... I think I have not put it in write way. In my particular case, SharedPreferences, Database are not applicable due to large file(.xml, html,etc) size My temp files may consume 1MB to say 10MB space. However, app deletes them as soon as they r not needed. Since temp filesize is little more, i am not sure if its a good option to store on device internal Storage. Hence one option left is SDCARD, but there to protect data, encryption needs to be applied...which probably i'll be doing now. On Apr 14, 12:40 pm, Dianne Hackborn hack...@android.com wrote: You are mixing up all kinds of things. Each application has a directory on internal storage where its *private* data goes. This is shared with all apps on internal storage; there is no per-app quota, though if the overall storage starts getting low a notification will displayed to the user which takes them to a list of apps sorted by how much storage each one is taking, for them to deal with the culprits. SharedPreferences is *one* way to put data in your private internal storage area. It is in no way shape or form intended for large amounts of data. It is for small settings data. Databases are another way to put data in your private internal storage. This also is not intended for big blobs of binary data, but works well for large amounts (megabytes) of structured data. Or you can just put whatever files you want in your internal storage, in whatever format you want. The sd card / external storage is generally for *shared* data that does not need to be protected from other apps. That said, you *can* protect it basically as well as you can protect your private data if you do some work -- for example generate a random key that you put in your internal storage (so other apps can't get to it) which you use to encrypt the data on external / sd card storage. This is basically how apps on SD card works -- the system generates a random key for created encrypted filesystems on the SD card in which it installs an application.

working as well --
intent-filter
action android:name=android.intent.action.VIEW /
category
android:name=android.intent.category.DEFAULT /
/intent-filter
/activity
SubActivity.java
//Here on GoBack button, I want to send control back to calling
Activity ii.e. MainActivity
/// code starts
GoBackButton.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
setResult(RESULT_OK);
finish(); causing
problem
}
});
//code ends
Whats happening is ...
My control is going back to MainActiivty on pressing GOBack button,
but the problem is since I am finishing SubAcitivty in GoBackButton
itself, it takes some time for control to go back to
onActivityResult() and do remaining task and launch another activity
say Activity 2,
as a result of which on pressing GoBack button, for few seconds ,
homeScreen (device homescreen) is dispalyed and then later, my
activity2 gets launched.
I want to remove that delay between GoBack button and launch of
Activity2
I wan to end SubAcitivty as soon as user navigates away from this
activity and send back control to calling activity. I also tried
setting android:noHistory = true instead of calling finish() but
nothing is working.
Please help :(

[android-developers] how to change behavior of default application in android
Hello All, I want to change default behavior of one of the in-built application like Phone/SMS/etc. I got to search on forums that there is an option in SettingsLaunch By Default There Clear defaults The Clear default button on right is disabled for both in-built and any other downloaded app. 1) Are there any special settings to disable it from custom(non in- built) app? 2) If once I change Clear Default using ClearDefault app available on market , is it possible to set the original default application back to active/defaults ? I want to change behavior of app after it is just about to complete. Can i get some event/ack that abc app has finished so that I can start my app after that ? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Optimization - Memory - Garbage collection
Hi all, I have a static instance singleton class object. I want that object to be garbage collected/null as soon as I close my application using back button. Whats happening is - My Object is alive, between two launch of application and hence retains the state. However,I am taking care of all instance variables by resetting them after their use by my own class.reset() method. What I want is to make my Class object eligible for gc as soon as I have come out of my applciation using back button. I dont want my object to stay on heap between two launches. As there may be a gap of few hrs / days between two launches of app on actual device. So dont want the object to be alive unnecessarily. I know, android will take care of gc when it will call ondestroy() at its own, but I think one should not rely on ondestroy(). Can anyone please suggest any way to destroy objects right after application is stopped ? (although process is still visible in ddms) Thansk in advance. -- You received this message because you are subscribed to the Google Groups Android Developers group.

A lot of people recommend unchecking Build automatically, Cleaning and rechecking Build automatically, people also suggest that it's a line that says import R. that causes the problem, but it feels like I've tried everything and I still can't make it work...

[android-developers] Re: Whether to use a Service or Thread for Http Connection?
Very good suggestion by John :) Thanks Good class to know. AsynTask seems to simplify the cumbersome handling of UI and worker thread. In short, it is just a fancy variant of Thread implementation. So, if i am geting it right, the answer to Sagar's question is Thread on top of Service for http connection. Plz correct if requried.

[android-developers] Re: Whether to use a Service or Thread for Http Connection?
Say, if i have to display the content of this blog in my application , then 1. I have a UI thread 2. From this UI thread, I should create an intent to call a Service which would then implement ASynckTask 3. This AsyncTask will make http connection and download any blog updates, will pass on the update to the UI activity for display. Please correct me if i am wrong somewhere.

You can use an AsyncTask in an Activity if the task has to happen while the activity is active. If the task needs to happen also when the acitivity is not active, (like when the user goes to other activities while the task is downloading stuff) use an AsyncTask in a Service.- Hide quoted text - - Show quoted text - -- You received this message because you are subscribed to the Google Groups Android Developers group.
