Android :: Do Intents Get Some Special Treatment By System?
Feb 19, 2010
I've developed an appWidget by inheriting AppWidgetProvider and adding it to the manifest as a receiver with the appwidget-metatag. Works fine. Two questions though: 1. It seems that the only reason to add APPWIDGET_UPDATE to the intentfilter of the receiver is to let the widgetpicker recognize it as an appwidget? The intents (update/enable/disable) it received no matter if they are included in the intentfilter or not. How come? 2. When adding a permission to the receiver to disable spoofed intents, I actually expected the APPWIDGET_XXX intents not to be received since they are(?) sent from a sender without the permission. Not so, they arrived just as before. How is this possible? Do these intents get some special treatment by the system?

I am attempting to listen for system fired Intents, specifically regarding text input, using a class extending BroadcastReceiver. I see there is an Intent called ACTION_INPUT_METHOD_CHANGED (android.intent.action.INPUT_METHOD_CHANGED) which I hope to be able to use to know when the keyboard or text input is attempted by the user. (I assume this intent will work as I can use an InputMethodManager object to handle keyboard related tasks)
My java code:
package com.BroadcastReception;
import android.content.BroadcastReceiver; import android.content.Context;
import android.content.Intent; import android.util.Log;
public class InputMethodChangedReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
if (arg1.getAction().equals("android.intent.action.INPUT_METHOD_CHANGED")) {
Log.d(this.toString(), "Event Fired");} } }

My gmail account has no problem getting push email. However, is there a way to enable my hotmail to receive the same treatment?
I haven't even been able to set up my hotmail address yet. It's a hotmail.co.uk address.

I have a list with some Belgian cities with accentued ( is that the right english word?) characters: (Liège,Quiévrain,Franière, etc.) and I would like to transform these special characters to compare with a list containing the same names in upper case, but without these characters ( LIEGE, QUIEVRAIN, FRANIERE) What i first tried to do was to use the upper case: LIEGE.contentEqual(Liège.toUpperCase()) but that doesn't fit because the Upper case of Liège is LIÉGE and not LIEGE. I have some complicated ideas like replacing each characters, but that sound stupid and a long process.

I have a ListView, and I want to do something special with the first item in the listview.
So, I setup an adapter, an item in separate xml a java wrapper for the item and I have a "render()" method.
Inside my render method, I realized that I can't do something like "findViewById(R.id.test)" because all the items in the listview have the same id. How can I get just the first item?

I see that as of API Level 8, you can request a handle to special directories with Environment.getExternalStoragePublicDirectory. This takes a type such as DIRECTORY_MUSIC, DIRECTORY_PICTURES, etc.
I'm looking for an equivalent directory for other media types such as documents (Word docs, PDFs, etc.). My HTC Desire has a "/sdcard/My Documents/" folder which looks like exactly what I want, but it has no DIRECTORY_ specifier for use with the above method. Is this a standard Android directory which I can rely on?
If I can't use getExternalStoragePublicDirectory, I have to use getExternalStorageDirectory instead which just points me to the root of the SD card. I can explicitly check for the presence of "My Documents" under the root and use it if it's there.
This is what I have:
CODE:..........
Is there a better way?

I do not have a device. I am testing on the emulator. When I send a message(problematically and through the device) with special characters I am not able to view them properly. For Example: When I send a message from one emulator to another say "~Ha". I see only the character "~" in the other emulator.
But when I send the same message from the DDMS, I do not see the problem. Is this a problem with the emulator or am i missing somthing. sm.sendTextMessage("5556", null, "~Ha", null, null);

I'm a college student, and there's daily specials at bars, salsa dance nights, special meetings, lectures, etc. And all these things happen around me. I don't want to just put them into my calendar and have them flooding it, but I would like some app to hold such things. Anyone know what I can use that isn't my default so I can retain my personal schedule and, if I want to do extra, can see this app's contents?

I need an advice. What is the best way to implement in android a list of such UI elements (see the ref)A list contains a lot of such elements (about 30-40). I'm using now relative layout and 4 text fields and I think it isn't a good way.I think it's too heavy (full list will contain: 30 relative layouts and 30*5 = 150 text fields).

I have a need to force my application to the front under special circumstances. I know its against the good coding philosophy but I am working on a turnkey solution where I control the complete device. The app is used internally as a business tool and supplied to the users on a stripped down device. I have searched but cannot see a way but know that it can be done as in the Application Protection app. This can react to the launching of an application and kill it / allow it by entering a password.

Question: My wife and I both have an Evo 4g. We live in the US. She will be traveling Europe for three months and I would like for her to be able to call me free through WiFi access. What app would be best for this situation? Something that is most like a normal phone call would be ideal. Also I would much rather be able to receive calls without running a special app. Simple and easy is important.

The App I'm trying to work on requires that when a special combination of keys are pressed ( irrespective of the keypad being locked ) a service / app is triggered.
How can I achieve this? My app's whole idea hinges on this particular part to work.
I am not here to take a "no" for an answer. If you are going to tell me that its not possible, atleast include an explanation as to why its not possible.

I am using Handcent on my Droid. I have it all set up to use a different tone to remind me of messages (at least I think I do). Instead, it just plays the initial tone as a reminder.
For example, when I get a text message:
<wild bird> -one minute- <wild bird> -one min- <wild bird>
But I want:
<wild bird> -one minute- <honk> -one min- <honk>
Where "honk" is the reminder sound. Anyone know why this might be happening?

Is it possible to develop an Android app that would answer an incoming call and play a recorded message to the calling party without the phone ringing? For example, if a specific caller called during certain hours play a message asking them to call a different number during those hours.
In a similar vein, is it possible to intercept a call and if it is in a certain list of phone numbers divert it directly to voice mail without the phone ringing?
Thanks for any insights into this

I am an Android app developer, and I have purchased a Nexus One device which I use to continuously test my developed Android applications.
Background: ----------------- One of the applications I developed uses a native shared library (e.g. myNativeLib.so). Only my application loads & uses this native library. I had developed this app before Android NDK came out. I pack my native library into my apk's 'assets' folder, and during my application start- up, I extract this native library from my package's assets folder to my app private directory (i.e. <assets> -> /data/data/<myappprocess>/ myNativeLib.so). Then I use System.load() API in my application to dynamically load this native library.
Problem: ------------ This application was developed during Android 1.5 (i.e. cupcake) days {I didn't have the Nexus One then}. The above procedure has been working without any problems right from Android 1.5 to Android 2.2 (i.e. Froyo). I have also tested the same on my Nexus One for Android 2.1 (i.e. Eclair) and Android 2.2.
The problem began the moment I recently upgraded my Nexus One to Android 2.2.1 via the FRG83 system update. Now, whenever I try to load my native library, I get the following error:
D/dalvikvm( 3653): Trying to load lib /data/data/<myappprocess>/ <mynativelib>.so <some address> I/dalvikvm( 3653): Unable to dlopen(/data/data/<myappprocess>/ <mynativelib>.so): Cannot load library: link_image[1995]: failed to link <mynativelib>.so
What I have Tried: -------------------------- 1. I tried my application using Android 2.2 SDK (emulator)...it works, no issues. 2. I checked out the latest froyo & android2.2.1 source code from Android open-source, built & tested my application + native lib using the latest froyo source...it built & ran, no issues. This should've taken care of any changes in the native code dependencies between Android 2.2 & Android 2.2.1 3. I even checked Android 2.2.1 source code for dalvik (java System & Runtime classes) + bionic (linker & dlopen sources) between Android 2.2 & Android 2.2.1 (using source checked out from Android open-source), but couldn't find anything consequential 4. I am unable to return my Nexus One to Android 2.2.

I've tried a bunch of roms but what so special about sense roms from the stock sense besides the fact they remove sprint bloatware and add a theme? I've tried fresh and myns etc. They just are basically stock sense with a theme and a different launcher and some added apps. I don't notice any special feature and people are saying how great they are but I am missing something cause they arn't much different.

Specifically music notes.
its not a horrible ordeal, just a very minor annoyance, HOWEVER
im curious as to whether or not theres some type of character set or language package i can apply that will show these types of characters.
example:
INCREDIBLE BROWSER
DESKTOP BROWSER
any ideas? p.s calling the phone a "DInc" is the stupidest thing on the planet.

I understand the concept behind not needing to use them when it comes to ram usage; if a program isn't active its ram can be released so it can be used by other applications.however, how does the android OS deal with cpu use by applications not active? this is the only reason i would think apps should be killed; there's nothing preventing them from using up cpu cycles while in the background.do they need to make special api calls to use cycles if not active?
