View 2 Replies View RelatedI wanted to understand what the $ sign and the number after a $ sign meant in a backtrace. For example, consider the following backtrace: at android.app.Activity Thread.access$ 2500 (ActivityThread.java:115) at android.app.Activity Thread$H.handleMessage (ActivityThread . java : 1745) In the first line, what does the number 2500 refer to? In addition, I couldn't find the function "access" in ActivityThread.java, and line 115 is just the beginning of the class. Can anyone help clarify this?

View 4 Replies View RelatedAs said in the Android Reference, the method getAccuracy() of android.location: "Returns the accuracy of the fix in meters. If hasAccuracy() is false, 0.0 is returned." But what does that mean exactly? The diameter or the radius? The Circular Error Probable (CEP), the 95-percentile or something else? I hope they are of the same type in GPS and GSM positioning. Does somebody know where these information are given into the system? As far as i know, are the GSM coordinates returned by a hidden Google API over a Web Service. So no chance to see an exact calculation. But where is the Accuracy of GPS calculated. I thought the GPS receiver only returns a dimensionless DOP value. And with Android 1.5 its not posible to read the NMEA sentences directly.
View 5 Replies View RelatedIn android, most event listener methods return a boolean value. What is that true/false value mean ? what will it result in to the subsequence events ?class MyTouchListener implements OnTouchListener {@Override public boolean onTouch(View v, MotionEvent event) {logView.showEvent(event);return true;}Regarding to the above example, if return true in onTouch method,I found every touch event(DOWN,UP,MOVE,etc) has been captured according to my logView. On the contrary,if return false, onely the DOWN event been captured. So it's seemd that return false will prevent the event to propagate. Am I correct ?Furthermore, in a OnGestureListener, many methods have to return a boolean value too. Do they have the same meaning ?

View 1 Replies View RelatedI tried enough to find in google & android this question. Also did several trials & errors, but couldn't get this question. was learning Android's "Draw Nine Patch" images. One basic I know is that, whatever image you process must be in .png format (if it's already in .9.png then it will be ignored by tool). However, couldn't understand what it literally means by "stretchable patches" ? what exactly happens when you draw black dots outside the .png image ? (preview pane shows changes happening, but I am unclear on how it makes those)When I draw black dots in left/top sides of image it shows some changes in preview; but why isn't there any effect when you do the same on right/bottom side of the image ? why this tool is used primarily for background, when we try to process on the image itself ?i am trying to modify a simple button.png (given in android sdk). Whenever I use this tool & draw black lines, it reduces the size of the image instead of 'stretching' it! Why ?What is the significance of options given below like, "show lock", "show content", "Patch scale" and so on ?I apologize for asking so many questions, but in Android online docs they haven't explained well for novice. If someone can answer these, it will become ready reference for all the begineers who search this forum.

View 13 Replies View RelatedSo, just reading around the forums and online sites, I guess Android 3.0 or gingerbread might be out around the holidays.Although the vibrant does meet the minimum requirements, google seems to want 3.0 only to run on superphones. If 1ghz, 4 inch screen, and 512 are min requirements.. This leads me to believe, that by the holidays, this phone will no longer be considered a superphone, there probably will be a 2 ghz. 4.3 inch, 1gb phone out. Why do I bring this up? Well I'm asking because, for those people who do not wish to root, and are depending on t-mobile/samsung updates to 3.0, what if samsung never releases a 3.0 update for the vibrant. This is the only reason I'm thinking about this phone.Just reading various sights, seems like google has made it clear, gingerbread 3.0 will be for superphones, and all other phones will stick to 2.2/2.1. I'm thinking by holiday season, samsung is going to put this phone in the "I'm sorry, you are stuck with 2.1/2.2 cateogry" because they probably will have a superphone out by then.If you can't get 3.0 on this phone via a true update, is it worth it? How can anyone find out, what Samsung has planned?I guess I don't want the behold II issue to happen on this phone.
View 31 Replies View RelatedIn an Android utility class, I want to get a system preference value in a class, but I don't have the context there, because the class that calls it doesn't have the context either. I've found that for Resources one can use the static Resources.getSystem() function. Is there any similar way for getting system preferences without context?
My class isn't an activity nor service. It's a utility class. Could give more info if needed.
How can I launch a contextmenu from a contextmenu? I'm trying to replicate the MediaPlayer action that happens when you long click a song, then click "Add to playlist" in the resulting contextmenu. When you click that menu item, another contextmenu pops up with "Add to playlist" as the title, and "Current playlist", "New", and however-many-playlists-you-have defined after that.

I can't figure what is exactly meaning the Partition Sdcard values in CWM.
I have an i9000, with 8Gb of flash. Some are system reserved. Available is around 6Gb.
When i run CWM, i can partition my sdcard, but i don't see what means the possible values (for 256 to 4096).
This is obviously not ruling the space left on /sdcard mountpoint (i partition to 2048, i still have nearly 6Gb available)... So what exactly means partition sdcard from CWM ??
i can't find an answer, and i dislike, when flashing rom, following commands i don't really master (generally a partition SD 2048 / SWAP 256 or SWAP 0).
I'm confused about the concept of the Context class. I see that it's a base class of Activity, but the Android docs also mentions the Context storing global information about the app environment. So in my app which has 3 activities, does that mean I have 3 distinct Context objects, or do they actually refer to 1 entity? Also, what is the lifetime of a Context object- does it live until the last component of this activity's process is garbage collected?

View 4 Replies View RelatedI often run into the following dilemma: I need some singleton-like object in my app (typically some central manager-like thing) and this object needs a context for various things. This means that I either have to pass a context to all methods needing one or have some sort of init-pattern to the object. Neither is pretty I think. What is the correct way of doing this? Or is this simply (even the definition of) a Service?
View 15 Replies View RelatedI'm considering creating a singleton wrapper for a Context so my model objects, if necessary, can open and read from a database connection. My model objects do not have access to a Context, and I'd like to avoid needing to pass a reference to a Context from object to object.I was planning to place into this singleton a reference to the Context returned by Application.getApplicationContext(). This singleton object would be initialized in my custom Application instance before anything else would need to or have a chance to use it.Can anyone think of a reason to not do this?

View 1 Replies View RelatedSo I'm working on a service that will handle requests to send data to a socket.I've done socket programming in a service before, but only within the same application. I'd like this to just sit and do nothing until any application wants to give it data to send. That's all well and good.I have register an intent filter and the usual stuff and can process the data. But I want to process the data coming from different activities in different threads (subsequent calls from the same application will be computed on the same thread).Is there a way to get the calling package or app or whatever? I'd prefer not to require passing in an identifier as an extra to prevent spoofing. (It's not a serious security concern, it's just each application needs its data processed in the order that it's received.)
