Android :: How To Open / Register A New File Extension In Android?
Jul 20, 2009
I have problem with adding a new file type to android(the file type is .comap).I need to run my application with this file from android browser and from file manager. I know that I need to write a special <intent-filter> for that,but I don't know how,because this format hasn't any special,registered MIME type.

Is there a way as an end user to associate particular file extensions or mime types with a specific application. For example, I want .djvu to automatically be opened by djvudroid when I click on it in astro. I am on a nexus one by the way.

I'm using JB 1.4.2 on Razr i. There's one thing that's annoying me a lot. I've installed the SNES Emulator SuperGNES and I've found that every single file type that have no app associated is showing SuperGNES icon and associated with it. Example: .log, .db, etc. Even files that have no extension is associated with it. The same problem occur when ZArchiver is installed. I don't know if it's a bug of these two apps or Android's in general. Remembering that this associations are shown only inside Android's native file manager. It's like every "unknown MIME type file" act like being the same.

I don't know if this is just a fluke or what, so I figured I'd come here and get some input. I have a locally saved HTML file with extension .HTML, which I had pulled from my Drop Box account, but I can never open it properly. Using Estranges, I just get a "cannot load" or something-or-other page. However, if I go to the stock browser and input file:/// plus the path... no problems. Any ideas as to the problem here? Really a hassle.

I have a big project about Android. So you know noobs can't use ADB and Fastboot well. I'll make a custom file extension. That is an script. That will be a custom script. So how can I make my own scripting language ? And how can I export a file format from scripting language ? For example; Perl' s file format is .pl and Shell' s is .sh and so on...
Imagine I made an scripting language. But how can I make a program for running that ?
Go on, my idea is; user will install executer program. And he/she can run special scripts with that. So rooting, bootloader unlocking will be pretty easy with that. What do you think ?
My scripting language's scripts will be like this:
[ADB] reboot; ( Calls adb reboot command )
[FASTBOOT] oem unlock;
And here is a rooting script in my mind:
[FASTBOOT] oem unlock;
[FLASH R] [FILENAME:twrp.img];
[MESSAGE] Put your device to sideload mode.;
[SIDELOAD] [FILENAME:root.zip]
[ADB] reboot;
So can use ADB and Fastboot commands without using CMD. .When user openes .myscript file with notepad, he/she will see that codes.

I use my file explorer a lot. It eliminates much of the "You have to put the files here" sort of requirement of many applications. And in many case - movie files for example - when you touch the file, it opens it in the appropriate application. There are exceptions like *.epub files. When I touch one, I get the famous "...does not support." message. So the question is, can I "register" Laputa (for example) to be the app to open *.epub files - Similar to the File Types dialog in Windows?I suppose this might require root access?

In Android, I am trying to make it so that the user downloads a font from the browser and I am able to view the font when downloaded. After multiple issues, I still have one lingering one: Registering the file type with the browser. When trying to download with the Emulator (2.1-u1), I get "Cannot download. The content is not supported on this phone". Okay, so maybe its my manifest file. Updated with this:
<activity android:name=".MainActivity" android:label="MainActivity">
<intent-filter> <action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
<catagory android:name="android.intent.category.BROWSABLE"/>
<data android:scheme="http"/> <data android:scheme="https"/>
<data android:scheme="ftp"/> <data android:host="*"/>
<data android:mimeType="*/*"/> <data android:pathPattern=".*zip"/>
</intent-filter> </activity>
Went back to the browser, and fails again. Restart the Emulator, still fails. Note that I got this format from posts here.

I have been able to register and unregister a broadcast receiver from the java code and know that a broadcast receiver is unregistered (even if it is not done explicitly) on its own as the process that registered it is killed. Now I have a broadcast receiver which has been registered through manifest file and not through the java code, and need to unregister the broadcast receiver from the java code. Since this, i think would need a reference to System context that instantiates the broadcast receiver.

How come this is the only file manager on the market (that I've found... I went through quite a few) that can open an HTML file from your SD card? I was a loyal user of Estrogen until I found that it couldn't.

I'm a novice user writing my first android application. I have the need to upload a file to a webserver from the device. I googled enough before joining this forum and not at one place did I find a suitable solution. I would like to know how to launch the file browser when user clicks on the "Browse" button to upload a file.

I don't want to store said file on the sdcard in this case. The file also cannot be storage directly in the apps local files directory. It needs to be in a subdirectory, so it cannot write the file using openFileOutput() and MODE_WORLD_READABLE.
The app may download files small files like pdfs and store them locally in a subdirectory. I would like to be able to have the user open these files if they have an app that can open them.
For example here is an intent for sending a pdf:
CODE:..............
path being something like: /data/data/packagename/files/subdir/example.pdf
That intent will open a pdf viewer, but the viewer is unable to open the file. I assume this is a permissions issue. I tried Mark Murphy's suggestion here: http://groups.google.com/group/android-developers/browse_thread/thread/4e55d869213483a9/b7270078ac1a2744?lnk=raot of using Runtime.getRuntime().exec("chmod 755 " + fileName); but it didn't make any difference. He also suggested a Content Provider but I would like to avoid it if I can because it seems like a lot just to get this file over to another app.
If the content provider is the only option, do I have to save the file to the content provider or can I just use the content provider as a pass through to get it to the other app when I need to?

I have created a app that displays all the content from res/raw folder. I need that when I click on .doc file it should open and I can view its content. I have ThinkFree.
Enter code here:
public class FileList extends ListActivity {
public static final Field[] fields = R.raw.class.getFields();
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<Field>(this, R.layout.row, R.id.weekofday, fields));
} @Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
//super.onListItemClick(l, v, position, id);
String selection = l.getItemAtPosition(position).toString();
Toast.makeText(this, selection, Toast.LENGTH_SHORT).show();
Intent i = new Intent();
i.setAction(android.content.Intent.ACTION_VIEW);
startActivity(i);
} }

In windows text files are displayed with notepad icon. When we double click the particular file it opens the notepad and displays the file. Like that I need to open the file from the download folder in android. I have used the intent-filter for register my ics files mime type. When I select the file in the download folder it just opens my application only. At that time I need to open / read the selected file. How to do this?

I've been using a droid eris for a couple of months now and have loved the experience so far. Unfortunately, the honeymoon is over and I've been trying to do some productive things with it (outside of playing Robo Defense that is =p).I've been having problems opening different types of documents. My two biggest problems are with Quickoffice and PDF Viewer.When I launch Quickoffice, I get the "Open file" window which takes a few seconds to load and a few files begin to populate in the list. After just a couple of seconds, I get a force close message stating: Sorry! The application Quickoffice (process com.qo.android.htc) has stopped unexpectedly. Please try again" This same thing happens with the PDF Viewer as well.However, I can use a file manager like Linda Manager to browse to a specific file and then open it within the program just fine. I honestly don't know where to start

I have an application that I'd like to add auto-update functionality (its not in the marketplace). I have all the code in place that would check to see if there is an update available and then i call something like this: Intent intent = new Intent(Intent.ACTION_VIEW ,Uri.parse(Configuration.APK_URL)); c.startActivity(intent); which starts downloading the file, although is there a way that I can programatically tell it to "open" the file to begin the installation process without the user having to go to the downloads and clicking on it?
