Android :: Modifying App Framework & Importing To Windows SDK
Feb 19, 2010
I'm primarily working on the Android SDK on windows, but would like to modify/tweak some functionality in the application framework.I have a separate ubuntu box where I downloaded the android source code, built it using "make" as well as "make sdk". I have a few questions in mind. Is it possible to import the binaries that I built on the ubuntu box into the android windows SDK? If so, what are the (proper) steps in doing so.For example, say I modified some functionality in the Activity.java file, then built it on ubuntu. I want to be able to make use of my modifications and continue my app development on my Windows SDK. Can I somehow import the framework binaries built from this step over to my windows SDK and continue my development from there? If so, what are the binaries I need and what are the steps to import them?

I don't think iOS7 is such an "amazing" upgrade. Some icons are hideous and almost all new features already exists in Android.But i have to say, i instantly fell in love with the awesome window-transtions when opening and closing apps, se below:
http:[url]......
I currently run a Nexus 4 (Jelly Bean, CM10.1 Linaro) with a modified framework-res.apk file with ICS transitions.I know how to create animations (I am an android developer) but wouldn't it be cool to implement them on our system?In the anims folder of framework-res.apk you find all of these xmls containing different animations
Code:
accelerate_quad.xml
accelerate_quint.xml
activity_close_enter.xml[code].....
Some of them are pretty obvious (toast_enter.xml for example) but i dont really know which one does what.

I have to move my existing contacts from HTC TyTn Windows 6 powered to HTC Hero on Android. Is there a way to export and import without going through google or any other cloud computing servers? I have PIMBackup running on HTC TyTn and that exports contacts in a CSV format. I have also located a new application (not tried it yet) will export them in XML format. Will this help with the importing? I am not able to find 1 application that will run on both the phones. I have loads of information on my contacts (from addresses to groups to different phone numbers) and I don't want to lose any of this information.

So I have the basics down... I can create a UI with the XML, I can show it and change the screen to another UI (another XML file) but how do I add to the UI?
Hard to explain...
Say I have a header (just 2 textviews) that will remain at the top and below that is a search box and button (main.xml). The user searches and I have it display the search UI (search.xml). This UI will have the same header (2 textviews) and below it will have several textviews each one containing a search result... Kinda like if you search for an app in the market. There's no way of telling how many results would be returned so I figured I would have to create each textview on the fly within the .java file. I'm not sure how to do this. Most likely would require a loop of some sort, but whats the syntax to create a new textview and display it right below the one above it? I'm working with linear here so I would assume just creating a new textview it will by default go to the next one down which is what I want.
Also, say I have 30 results... How do I get those to scroll but leave the 2 textview header in place? Would I create a ScrollView and put the new TextViews in that?

In an Android application I am writing, the styling for my various TextView elements is defined in an xml resource. I would like enable the user to change certain styles such as android:typeface using a PreferenceActivity. Is there a way to modify a style resource programmatically such that all associated widgets will update correctly? If not, must I manually select all widgets by id and change their styling?

I am writing an application that will run on 2.0 and above. Now, I am thinking of adding the Data backup feature to the application. Is there anyway to modify the manifest file to include the metadata only if the phone is using Froyo(2.2). Ideally, i would like to avoid creating a separate application for just Froyo.

Have a question regarding RotateAnimation. If I do not set the property FillAfter to true then the image in my view, that I use RotateAnimation to animate, returns to the initial position after the animation is done. My problem is that when I set fillafter to true when I later set the image on my imageview to another image than the one I animated some kind of transformation is applied to that image also.

I am looking for some answers from some of the experts here. I have a project in mind that I want to start. It is about using HTC's Touch HD phone as a device in a museum with rich media/video about the art and the artists on it. Besides the videos and animation, I also want to show some content from a web browser. Now my biggestest issue. I do not want that the museum guest who pick up the phone for the tour get to see the standard Android user interface. Is there a way to develop a new user interface that would start up directly once the phone is turned on? It should then automatically start the app with the museum infos. Later I may want to add some GPS functions and even sms and photo taking, etc....
What do you think, how flexible is Android to allow that?

I need to load an audio resource and play it, but I also need to be able to modify some parameters (like the volume, or the playback rate) while the audio is being played. For example, I might want to play a 10 seconds audio stream, and change the volume only after 3 seconds. Is there a way to do it? I've been experimenting a little with AudioTrack without results.

I have a rooted desire, but I have a troublesome app that won't update and I can't delete. I have seen others who have had the same problem, and a solution is to rename the app .apk.old and then redownload it, but I can't find a decent app to do this. I do have superuser permissions.

This question actually has two parts.
The first part:
I've been developing my first app for a couple of weeks now. I have 5 screens and everything seems well. However, I'm considering changing the app's navigation to a TabView.
I haven't delved much into it, but I'm hoping someone can save me a little bit of time. It seems that people don't generally place Activities inside each tab. They simply point the tab content to a View. This is where my major setbacks are. 1) I already have Activity classes full of code and 2) I can't quickly guess how the structure of an app using TabView looks. For example, where do I put the handler code for clicking a button on a View? Does it all just get dumped into the TabView Activity somehow?
What I would like is if you could please give me a quick synopsis of what I'm looking at doing, answers to any questions you think I may have, and point me toward some resources for creating TabView applications. A quick Google search really just shows me how to create a TabView Activity and add a couple tabs to it. The code doesn't go any deeper. For example, say I have a layout xml to show in one of my tab's content pane, where does the code go for clicking a button I have in that layout?
The second part:
I've added a TabActivity to wrap the Activities I currently have in. At the moment I have Activities populating the content of my tabs (though ultimately I'd like to do this in the most efficient fashion, which doesn't seem to be having Activities be tab content). I've noticed something rather annoying. My MAIN Activity is an Activity I wrote for my user to log in to their account. After logging in, they are taken to my Tab Activity. Here is what happens:
When I am on my Tab Activity and I "minimize" the app by clicking the Home button and then launch it again, I don't get taken back to the Tab Activity. I get taken to my log in Activity. Why? I don't have the launchMode of my Tab Activity set to singleInstance... or is it singleInstance by default? How can I make the app re-launch showing the Tab Activity (ideally by setting some parameter, assuming I'm doing something wrong, and not having to save this data off somewhere and reading it and programmatically telling it what to go to)?

What I wanna do is downloading one thumb after another with an AsyncTask and step for step change the standard image with the downloaded one. How to realise this?
The ListView contents are managed by an enhanced ArrayAdapter.

I have had DC 2.08.1 installed for about 2 weeks with no issues. I decided to go ahead and partition the SD to utilized apps2SD as I was having memory issues. That process, while not smooth, went through okay and the SD card is working with the partition and apps2SD. However, ever since that was completed, my Windows 7 box no longer recognizes the phone either as a phone or as a drive. My Linux laptop recognizes the drive without issue.
Any suggestions on how I can reintroduce my phone to the Windows box, at least as a drive?

I've read up quite a bit on the exception thrown while using BaseAdapter, but i can't seem to find an alternative solution: Make sure the content of your adapter is not modified from a background thread. What i want to achieve is to keep a copy of a message queue in memory, and use this message queue to populate the BaseAdapter for my ListView. The reason im doing this is that the message queue will keep getting messages from a socket even when the ListView is not currently present (for example a chat window).
The problem comes when i have the Activity with the ListView in foreground, BaseAdapter binded to the message queue's data, and a message comes in the socket. Adding the new message into the queue will throw the exception mentioned above. Unless i pre-populate my BaseAdapter with the message queue (as in the BaseAdapter having its own message queue) and updating both of them when a new message come in, i can't really find a way around this issue. I don't really want to double up the effort on keeping those 2 queues up-to-date like this, surely there is a better way of doing this? Send broadcasts around doesn't work either because of the potential delay in the adapter serving a scroll and the notifyDataSetChanged call is made.

I'm developing a mobile web browser application for Android which supports complex script rendering of Indic scripts.
For this, I used a currently available open source web browser for Android (which is licensed under GPLv3) & modified its code to support complex script rendering.
Now the code of the browser is from that open source app & the code of the complex script rendering part is from me.
My question is, Can I publish this application in a different name under the same license? (i.e. If the name of the open sourse app is "ABC Browser", can I publish the modified app which is able to support complex script rendering in a different name such as "XYZ Browser" under GPLv3 license?)

Is it possible to modify the folder grid width within android. For example, by default if I have 3 apps within a folder it will be displayed within the folder in a 2x2 grid with the top two spots and the bottom left occupied with an app. Instead I would like to modify it to be a 3x1 horizontal grid.

I have a HUAWEI Y300-0100, and it comes with a funny feature: every time it can't connect to WIFI a popup message appears saying that if you switch to data plan charges may apply.
I am constantly switching between WIFI/no-WIFI zones so that message really bothered me, and I searched a way to disable it.
Presumably, the only way to do that is by modifying a system file called "build.prop". I already had my phone rooted so doing so wasn't very hard.I used Jota+ to change a setting from "true" to "false" (ro.config.hw******), and saved the file in the root of the SD card. Then, with ES File Explorer, I renamed the "build.prop" in /system to "build.prop.bak" and copied there the "build.prop" I previously saved in the SD root.All seemed to be fine, except that after rebooting my phone it could not get past the HUAWEI logo.
Android recovery mode seems to work, but I don't know how to use a lot of its options nor I want to do a Factory Reset if there's a better alternative.Is there a way to modify system files before booting Android? I really would like to try to delete the "build.prop" file and rename the "build.prop.bak" back to "build.prop".

In my android application, I have an Edit Text. When I click in this field, the soft keyboard appears, expanding from the bottom of the screen. It seems to actually modify my layout, pushing contents up wards. When I dismiss the keypad, it retracts, and I see my layout re-expand to take up the space it previously occupied. Is there a way to get the keyboard to simply appear "on top" of my layout, so that I don't get this somewhat unpleasant relayout animation? The Edit Text is pinned to the very top of the screen, so I don't have to worry about the keypad hiding it.

Since my application cannot be run in root mode, is there any alternative solution where i could do such modifications from my application point of view.

This tip comes in courtesy of Mark, who was kind enough to help out fellow Android addicts get their contact syncing issues sorted out. While it?s easiest to just use gmail to sync contacts and calendar, it?s certainly not required. Here?s how you can back up your contact list for easy retrieval anytime you need them. Open your contacts application Make sure All contacts are visible, unless you only want to back up certain groups.
Hit the menu button
Hit the Import/Export button
We can verify that this works on HTC Sense phones, as well as the new Galaxy S series phones. If you?re using something a bit more vanilla, you will have an option to do the same thing but using your SIM card (through SIM Manager in the contacts menu) instead of the microSD card. Lastly, if you?re using the latest CM6, you have the option to do both!
