I am a C programmer before, and I am looking into android source code right now, some JAVA syntax is confusing, I am not sure whether or not it's android related, see:
CODE:..........
1) What's the meaning of Override? Is it ommitable?
2) What does the "synchronized" mean?

I want to build an notepad-style application on android that will have syntax highlighting. But when I search around the web, I find the syntax highlighting can be done only through use of an awt class. How could I syntax highlight in maybe a custom EditText or TextView view? I know that the release of a syntax highlighter is sort of anticipated, so I want to add my syntax highlighter on the market.

View 5 Replies View RelatedIn a recent thread, someone suggested to me that using Airplane Mode can chew up battery. Initially, I thought this seemed pretty silly, cause all it's really doing it turning off the wireless connections (how could that use more power?), but I had no reason to doubt this person.
I figured this evening, I would simply turn off my WiFi and Mobile Radio using the toggles. I noticed that your signal bars do not disappear when you turn off the mobile radio via the toggle. In fact, I can even place a phone call!! Not a very effective toggle in my mind.
Can anyone drop a little science on what's going on here? Is the Mobile radio ONLY for data? If so, is there a missing toggle widget in HTC's collection on this device? And ultimately, what is the airplane mode doing (and how could it not conserve battery over a fully "on" state)?
Anyone know of a Subversion client for Android OS? Same goes for a syntax highlighting text editor on there.

However this page defines it as:
CODE:..........
I thought I had a decent understanding of what was going on until I saw this second example. In the first case, you need the + character so that id 'label' is added to the R file, correct? In the second case, would the EditText's id not be added to the R file because it does not contain the + character?
Also, the second example does not include the android namespace on the id. Does having or not having the Android namespace affect whether that id will be added to the R file?
In my XML values strings code, I have a string with some text that I want to have only a few of the words in color. I also want to have a new line for some of the text.
I can do things like: < b> my bold text < /b> and that works (leading space added for this post).
I try to tag the text with color but no color shows up and there are no errors.
CODE:.............
I also try adding a new line - I've tried things like:
< LF> some text, space at beginning only for this post < /LF>
< CR> this didn't work either < /CR>
< p> some text, space at beginning only for this post < p>
But, no new paragraph / new line, carriage rtn happens.
Where is there information about the syntax of <shape> xml files. These can be used to define 2D graphics as I understand it. There are few spotty examples in the samples directory but that is all I have found.

I need to display a single list, ordered by date which contains different types of data, images, video and whatnot.
I guess you could have one separate table for each type and the use something like FULL OUTER JOIN (simulated as sqlite doesn't support it) and sort on date. But this would be complicated because I still need to have unique IDs across all tables.
Maybe having a master list which has ID and date, and then JOIN in the types tables? But how bad is the performance of this using sqlite? I really like to avoid having a super table which contains columns all the combined types could ever need.

Just getting started here. Working on an Android application, which needs to execute a google web search from within a ListView activity and display the results in that List View.
Such search would always be for the same "static" subject, such as "bowling alleys in Chicago...", so, the user will not be entering any search criteria. What is the proper way to accomplish this, please?
i am about to start learning android app using java currently i am using eclipse but i have some questions.

2) does the code syntax of unity android abd eclipse are pretty much same? or i should learn it like new lenguate?
I am prepared to be humiliated on this, but I am not sure what is wrong. I am just playing around with Android development and am just making a simple application that will print out accelerometer to a TextView.

I've run into the following issue:
Say I have an Animal class, which is parcelable, and I have a Dog class and a Cat class, which are subclasses of Animal and also implement Parcelable.
Say I have a service with the following AIDL interface:
sendAnimals(List<Animal> animals);
Now I'm calling this remote interface from some client application, passing it a List containing Cats and Dogs. What happens now is that android calls the Cat's and the Dog's writeToParcel() methods at the client side, but at the server side, the Animal's CREATOR is used, which calls Animal's readFromParcel() method. So the right data is sent from the client, but the wrong unmarshalling code is executed at the server.
I have tried to put this in the AIDL file:
sendAnimals(List<T extends Animal> animals);
This results in a syntax error from the aidl compiler though.
My current workaround is as follows: - In each specific Animal subtype's writeToParcel() method, I write the class name as a String into the Parcel as the first element. - In the Animal's CREATOR.createFromParcel() I read the first String out of the parcel, and based on that I create the appropriate type and call the appropriate readFromParcel() method.
I think this is kind of ugly though. I would expect the android framework to take care of this for me.
(My application is not actually dealing with animals, this is just to make it simpler to explain the issue)
I have been working on a update-script for updating the radio without the vzc update. mainly for rooted users. however i cant seem to get the update-script to work properly.

I have already posted on their developer group but based on everything I've seen I don't expect a reply. I have a strange problem. When I added and adview to my app it imported a bunch of comments that all start with /** Eclipse is acting like it is not a comment. Although it isn't erroring out it has now marked anything starting with R.id as not existing. Is this something I can remedy in eclipse or is it time to chuck my dreams of being mega rich off of all the admob revenue I will be receiving?

View 2 Replies View RelatedI'm using the following to draw rounded-corner rectangles in my Android application and it seems to be working alright but with one minor problem:
CODE:.......
(Adding labels to the rectF's defined above follows) ...
The strange thing is that the two ends of the rectangle aren't rounded over the same. The left-size quarter circles are noticeably smaller than the ones on the right.
Anybody experienced anything similar? It's weird enough that I might change my mind about the round corners if I can't do anything about it.... And if I knew how to do a screen capture from my Android, I would.
The rectangles in question are 78 pixels wide and 48 tall, if that helps (and since ykatchou may be onto something).
Java packages like Java.io, Java.Lang etc used in android, are they different from Java packages in windows ? means specially made for android ?
