Looking at the Android tutorials such as the Notepad tutorial, I noticed that almost all variables are named starting with the letter 'm'. What convention is this, and where does it originate from?

I'm writing an android app that requires binding a JSON object into a domain entity with the keys from the JSON as instance variables. Since there are several domain entities, each with different instance variables that the JSON needs to bind to in the app, i'd like to write a method such as ths following: Loop through all the instance variables from the domain if a key exists in the JSON with the name of the instance variable, take the value for this key from the JSON and set the Domain's instance variable with this key name equal to this value. The reason i'm interested in the doing the binding from the class to the JSON is because if the JSON changes for some reason, I don't want it to break the app when the instance variable doesn't exist in the app's domain for a specific JSON key.

View 2 Replies View RelatedI think this has to be a problem with the SD card and scanning it, but for some reason after syncing my phone, plugging it into the computer to charge, or even plugging it in to charge in the car, my music playlists seem to be duplicating all the time. I have loaded my playlists using Doubletwist (Slower than hell freezing over), I have tried Doubletwist, Mixzing, Cube, and Zimly and all have shown some or all of the duplicates. I have had it with Mixzing because of this, but the others seem to be doing it as well, just not as much. I have actually had up to 6 copies of the same playlist at one time. There is still only 1 music playlist that has songs in it, but there are 2, 3, or up to 6 copies for some reason. Another strange thing is the original actual playlist has each word starting with Capitals, but the copies are are small case. I've looked all over my SD card to see if I can find where these "phantom" playlists are stored, but I haven't found anything yet.
Also, after that stupid Froyo update, my phone won't allow me to play anything from the SD card when it is plugged in. Yes, I have tried changing the setting from Charge only to all of the other 3 options at one time or another, but in my car, it refuses to allow access to the SD card when plugged in regardless of what I do or what setting I have changed. Not impressed with the Froyo update AT ALL! This morning my SD card decided to lose all of my videos that were on it (5 GB worth) and about 1/3 of my music. I have no idea where they went, but they are gone. This phone was awesome in most every way until that stupid update, I wish I could go back to 2.1! My Pandora sucks now, my Multi-touch keyboard won't work anymore, I lost a whole bunch of files off my SD card as mentioned above, and I haven't noticed a single benefit other than my camera opens quicker now.
Is copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

View 1 Replies View RelatedIs there any method to let you get the keycode for a keyboard letter. E.g. public int get KeyCode(char letter) {...}? I had a look but can't find it and I can't find a way to make Auto complete start filtering from predefined input in the box, so I'm emulating key inputs to make it do this.
View 3 Replies View RelatedI've written an Android app that needs the short timezone name in which the handset is currently located.I'm using the following code: String timeZone = Calendar.getInstance().getTimeZone().getDisplayName(false, TimeZone.SHORT);When running in Chicago, this returns "CST". In New York, "EST". In Strasbourg, France, it's returning "HNEC" (Heure Normale de l'Europe Centrale in French).
The timezone in this location is referred to by some as "Central European Time" (see Wikipedia's Time zones of Europe).I'm passing timeZone off to a third-party system which very much insists on getting "CET" (not "HNEC"). Is there an API call I can rely on to return the three-letter (and, I think, "more modern") short timezone name? As my code runs in more and more locations, I'm guessing this problem is going to occur elsewhere, too. I'm really hoping to avoid maintaining some sort of map of three-letter to four-letter short timezone names.
just wondering if anyone else here ever has this issue and if theres something to fix it? im using swiftkey and sometimes it just decides to go nuts and types a letter 2 or 3 times even though i only hit it once and then the word suggest screws up and also when i hit the spacebar once it goes nuts and puts in a period and starts a new sentance.

View 2 Replies View RelatedI called my main activity Main, and Eclipse created Main.java and res/layout/main.xml for the layout.
Is there any reason why Eclipse dropped the uppercase "M" for the layout file?
Was I wrong to use upper case M for the name of my Main class (a Java convention, types start with uppercase, objects with lower case)?

View 6 Replies View RelatedI developed my first (small) Andoid application using Eclipse and are now ready to transfer it to my Galaxy S mobile device (develping for Android 2.1)
Following another thread in SE, I changed the run mode in Eclipse to manual in the hope that I would be able to chose my phone and/or AVD every time I run the program.
The popup list howerver only show the AVD, my phone is not present in the list.
So obviously, my Samsung Galaxy S device is not recognized. Howerver, I can transfer to and from the device using a drive letter, so the USB connection is working properly.
Anyone any idea what I am missing here ? I'm not sure if it is an Eclipse problem , or a driver or ....
Simple concept, I feel stupid for asking. Let's say I typed that as "Simple concept, I feel stupid for basking" and tapped the screen to put the cursor after the B in BASKING to delete it, but accidentally inserted before the B. How do I delete that without struggling to get the cursor exactly after the B? On a BB you can just hit the ALT key while hitting delete and it would delete the B after the cursor. I can't seem to figure out a simple typing issue.
View 11 Replies View RelatedLoving the phone but every once in a while - like three times yesterday and once today the touchscreen goes haywire. I click on an icon and it doesnt register or the icon below is activated. On the keyboard I tap a letter and another key is activated. If I turn off phone and then back on all is perfect again for a while. It seems to be happening in the lower third of the screen. Anyone experience this? Do you think software or hardware? Im thinking software because the reset fixes problem.

View 4 Replies View RelatedI have some xml files, and I keep them in raw folder. Now, the problem is that I have to use them with variable name according to my application condition. But I don't know how to fetch them. The main thing is that I am not getting that how to give the path of my xml file in application.
For example:
My file application.xml is stored in the raw folder and I have to access it with a variable name.
String xmlName= application.xml;
How can I fetch my xml through xmlName variable?
I'm trying to use a Condition Variable to control the execution sequence of two threads. I can create a Condition Variable in one thread and block on it. But I would like to be able to access it from another Thread and unblock it from that thread.. ? Blocked Thread i am planning to keep as GUI thread and it should update the messages which are sent by b/g thread on the screen during its block state and will be unblocked by b/g thread in the end by calling open(); method.
View 3 Replies View RelatedI have this code:
hubSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

View selectedItemView, int position, long id) {
final MediaPlayer mp2 = MediaPlayer.create(Textbox.this, R.raw.hero);
mp2.start(); } public void onNothingSelected(AdapterView<?> parentView) {

(The code basically runs when a new item is selected of a spinner and then plays a song, which later will be a variable based on what was picked, but I'm fine as it is for now). And I want to be able to use 'mp2' out of this public void, (I want a button which pauses it). How can I do this?
Anyone know of an audio player that will speed up the playback? It would be nice if it could keep the pitch the same but sped up is the goal. I used TCPMP on the Treo. This is great for listening to podcasts in a fraction of the time. Depending on the original audio, I can generally make everything out up to +25%.

View 4 Replies View RelatedI have noticed in my application(s) that after a call to Activity.finish() that the static variables that I declared in my classes still hold the values that they were changed to during the activity's life cycle. Upon the re-launch of the activity, the program does not re-instantiate the variables as declared or set them to the default java behavior. Is there something that I can do to cause this to happen, other than re-setting every static variable in my application?
