I was wondering if there is a way to observe the system calls in Android using a service.Is something like this remotely possible using Java or do I have to get down into native code?

In android, how can I observe for any changes made to a contact?
I know I need to register for a content observer? But what should be the URI for passing to the registerContentObserver function?
Here is what I tried code...
But I don't get notified when I change the phone number of the contact.
I need to detect Android Clipboard's content changes, and register the changes, but I can't really understand how to achieve such result.
There are a lot of clipboard managers around, but I found none open source, and it's difficult to believe they work by checking the clipboard every 15 seconds.
Is there a good method to observe clipboard changes?
Is there a way to observe a bluetooth pairing and then be aware of when the connection no longer exists? Basically I want to observe when my phone connects to another device and what that connection is dropped to that I may execute an action based on that connection.

Is there any way I can find out the system calls invoked by Android for specific tasks?For example, for writing/deleting contacts or writing/deleting SMS what are the Linux system calls invoked by Android for these tasks?I can't find any links explaining on this.

View 2 Replies View RelatedI 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.
Phone: UK Galaxy S Issue: Recovery boot error message in red writing
Multicsc : can not access to / system/csc/VOD/system/
Background: I have been trying to root my phone from information found in a youtube video. All went well and the little ninja bloke with the sniper rifle was in the app list. Tried installing busybox and was told that the phone was not rooted�..
I think I ran the root application again and at some point I started getting this error message when in recovery. I have since run the one click root method to unroot the phone and the little nija dude is no longer there. Since I rooted the phone it will no longer connect to my wireless network, it finds the network and attempts to obtain an ip address. After a few min it times out and tries again. When I load the phone recovery the error message is still present.
Can we modify the system while the phone is booted now that we have the unrevoked recovery flash tool? is this what NAND unlock means?

Not sure if this is technically the "silent bug" but calls do not even show up on the phone, they just appear as "missed call from...." no noise no other notification. I restarted phone but it did it again right away. Phone does show the 50% bug in battery info.

If I were to write an improved version of - let's say - TextView. Is it possible to make all app's on the system using this class, basically replace TextView? How are the java classes on the Android system, are they compiled, can I replace the library? Is this protected?

The screen doesnt light up and no options for receiving calls. This happened before I installed Google voice. I disabled Google voice and still no joy. Everything else works. I can make calls, browse over WiFi and 3G.

How to SET system colours, but I need to find out how you GET them - how do you find out what they are?
On the Samsung Galaxy S for example, the Tab views, the ListView highlights, Menu Items and Summary line on the Preference Screen are all blue.
There are many apps which immitate the style of the Preference Screen and I want to do the same. Obviously I cannot just hard code and set the colour to Blue, as other handsets use different colours.
The question is, is there a way to programmatically find out what colour the Preference Screen Summary Line, Tabs, or ListView selections are, so that you can then set that against a TextView elsewhere in your app?

This brings up 2 questions: (1) Why did the emulator deny other permissions in addition to those 4 system ones? (2) How could an app get the system permission? If this can only be done by building a custom Android like an OEM build, where in the Android platform does it check for system-level permission?

View 5 Replies View RelatedI downloaded new Android SDK 1.1 release 1. But I cannot find new system image for Dev Phone 1.
I thought that new system-image will be included in new SDK.
Where is a system-image for DP1?
So i realized today on my way home from work that my cars Clarion CD deck has a USB connector for hooking up thumb drives to play music off of them. I figured this HAS to work with the G1 and it does!I was able to hook the G1 charge and play the music off the SD card through the G1 with ease.Just set the G1 to act as a usb drive, and you can play music and charge your phone via USB while driving.So keep that in mind if you're going to be getting a new car CD player, get one with USB (pretty common on new CD players) and you'll be glad you did.
