General :: Method Hooking - How To Get Other Apps Data
May 15, 2013
I just came across this WhatsApp widget for Root which is able to display recent messages. I was wondering how the developers managed to get the data from WhatsApp.
As of now, I can think of three possible ways:
a) The widget refreshes its contents whenever it detects activity on the WhatsApp message database.
b) The widget "hooks" methods that get called in one of WhatsApps activities when new messages arrive and mirrors the messages into its own database.
c) The widget listens for push messages with the WhatsApp signature or listens for traffic between WhatsApp and their servers.
I use the termin "hooking" because of the way iOS tweaks are written, I have no idea if this is possible on Android. Which way is more likely?
Let me elaborate on the background of my question: I noticed that WhatsApp groups new messages as a single item in the notification window. I'm thinking about selling my iPhone and getting an Android phone, but I would like to have a preview of all incoming messages like iOS's notification center.

I need to take pictures with my application, but the only thing I am finding are examples of how to create a camera activity. Is there a way I can call up the phones native camera instead and get the byte[] data back instead of creating a camera activity myself?
I am asking because I would like to take advantage of the normal features like zoom, flash, themes, etc that the user would get if they push the camera button on their phone.

I release a class. In the class, there are public fields that can be written. I want to register the callback function which will be called right after my field is accessed. I think I can do that by using JVM tool interface which is supposed to be used for a debugger software. JVM tool interface:
I'm not sure same interface is working on android. or, They provide another form of interface to get a notification of a field access.

I hope this question hasn't been addressed before; I've tried searching google but I may not be searching with the right keywords:
My Droid (running NexFro 1.01 - about to install BB with NexFro in ~20 mins) has been automatically mounting my SD card to my PC since installing Froyo last Saturday. I didn't have this feature enabled before flashing to Froyo, and I've tried a few roms since Saturday and they all have this feature auto-enabled.
This normally wouldn't be an issue, but this week I have been traveling with my job and I have been using tethering quite a bit, and would like to be able to charge my phone from my laptop without mounting my SD card every time.
Is there a way to disable this feature? Also I'm not sure that it is a feature at this point, as I haven't seen any other forum posts about this one any of the Android forums and I can't be the only person who doesn't want this feature enabled by default.

I have a tab widget where one of the tabs is a chat-type feature. I want to update the chat data at an interval (variable depending on whether the chat tab is active or not).
The best approach seemed to be using an AsyncTask in my main TabActivity class, as that would avoid any issues of the chat activity being destroyed while in the background, while an AsyncTask was running. I wanted to ensure that the Activity isn't destroyed and recreated, thus causing my AsyncTask to be unable to modify the actual active Activity's data.
However, now that my AsyncTask is in the TabActivity activity, I don't have a direct way to call my Chat's ListAdapter notifyDataSetChanged() from my onPostExecute() method anymore. Is there a way to get a reference to a given Tab's current Activity from the TabHost/TabActivity?
Or, alternatively, can I assume my chat activity will never be destroyed as a child activity of the TabActivity activity (well, never destroyed while the TabActivity is active at least), and then just put the AsyncTask in the Chat Activity?

When I setup my A100 (running the ICS OTA update), I didn't have an SD card installed. It created it's own "fake" sdcard which applications use.
Now that I've added a real external sdcard, I can't get the applications to use that for their data instead of the "fake" location.
I've copied everything from the "fake" location to the new sdcard.
I suspect the problem is that the new, real sd card is called "external_sd" and the old, "fake" location is called "sdcard".
Do I need to reinstall those applications?
I am NOT trying to move applications to the external SD card; I just wants apps that normally store data there to do so instead of in the "fake" location.
Also, I am not rooted.

I've noticed that even when I have 3g or 4g, certain apps never connect to the Internet. The apps I've noticed that have this problem are sound Hound, Google now search, spotify and words with friends. These apps will fail to connect to the Internet and say I have no signal, yet I can open Google Chrome and open a Web page no problem (even pages I don't visit that aren't stored in cache) or use the Chive app.

I'm looking for some apps which can let me compress the data because my ISP provides unlimited 3G although the speed drops to 15kilobytes/s (not to be confused with kilobits) after 500MB of usage. Is it possible that i can compress the data usage with an app so that it takes longer for me to use 500MB.
Also i mostly listen to music videos on youtube as i'm driving around so are there any other alternative apps which allow me to listen to music but can run on a speed of 15kB/s?

I'm working on a custom ROM for my Toshiba Thrive and I'd like to install some apps with data already placed on installation, but I can't find out how. An example would be ADW as a launcher. Right now, it boots and immediately goes to the welcome screen for a fresh install of ADW. I'd like to make a default theme for ADW so that when someone installs the ROM, they can avoid that initial setup of ADW.

I'm running JB 4.1.2 and I've pretty much used up all the internal phone storage with installing games and other apps. I have an 8MB external SD with nothing on it and I'm basically wanting to transfer either the whole of android onto it if thats possible, or alternatively if thats not possible then just the larger files and folders like game data (for example GTA vice city obb takes up a whopping 1.5gb alone).

I recently updated my android to 4.3. A lot of people say that if you get a big update, it is the best to do a factory reset for faster performance. Is that true?
If that is the case, is there a way to do a factory reset and keep some data of some apps? Like example, i have an app that I spend my money on to buy ingame items and such. If i do a factory reset, all my ingame items will be gone and have to restart everything.
is there a 100% safe backup and do a factory reset for me to keep my app data?
