I'm having some issues with the old "Cannot make a static reference to a non-static method" error in my Android program. I am creating a sand falling game (similar to the Powder Game) and I created a class called Control to create a Control Bar at the bottom of the screen with a slider for brush size (that works fine) and a button to pop up a Dialog to allow users to pick the selected element. However, when I call DemoActivity.showDialog(2) from my code, it gives the static reference to non-static error (DemoActivity is the main activity of my application). I also tried changing it to just Activity.showDialog(2), but I got exactly the same error!
Here's my code:
CODE:................
I fixed it by adding the following to my Control.java code:
CODE:..........
And then calling control.setActivity(this); from my onResume section of DemoActivity.java!

I have Eclipse Juno and I'm working on an app with that.
The main activity will have a scrollable menu that takes you to all the other activities.
So the general structure/outline right now:[HIGH]Relative Layout ImageView (header logo type thing) ListView (the actual scrollable menu)[/HIGH]Here's the problem though... I can't find any simple list tutorials. I can easily make a single line list work but I need to make a two line list and one that is static, not dynamic and no examples are out there for that. It's like if you want to make a 2 line list, you can only learn how to do it in the most code-heavy ridiculous way possible.
Essentially what I am looking for with the list is this: Item one: Centred, bold, non selectable title (Resources)
- Item two-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
- Item ??: Centred, bold, non selectable title (Tools)
- Item ??-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
Nothing dynamic that is ever going to change, no super complex wonkey calculations, just to simply have the data set in stone (preferably via XML) and to call it into the list.
I experimented with some of the other list views and no matter what I did, I could get, via editing the resources and NOT using Java, more that one item on a single line but it wouldn't format it properly according to the layout I guess because I haven't got the ID correct or whatever I don't know.
I mean, all the examples I've seen for a 2 line list are extraordinarily over-coded and just bloated. I mean I have a website I am still working on in C#/ASP.net that has far more complex things in it with half the code that I've seen for the examples of the two line lists.
I tried on my own to figure it out (I am decent with C# and vaguely familiar with Java, self taught, and programming for some other systems like Python, again all self-taught), but like ALL coding references, they're organised by the actual code you implement (that you don't know) instead of by what you want it to do (so you have to search the whole code base to find something that you don't know what it's called but know what it does). >:C
I have been finding it convenient to extend Handler in many of my activities to handle messages specific to the activity. The handler sublass is an inner class of the activity and needs to access its state. I am wondering if there is any performance difference between making the handler subclass static and passing in the activity explicitly in its constructor or making the subclass an "instance class" and letting the vm worry about my accessing members of the containing activity.
The static approach:

Why should a static method in java accept only final or non final variables within its method, but not static?

View 1 Replies View RelatedI was working on Freescale iMX31 board, I ported android and it was working fine , but when it came to integration of WiFi & Bluetooth, android forum recommended me to do static compilation for porting over android !
Can I know why some drivers have to be statically compiled before it is ported over android? It was not the case with other drivers which when integrated with android, they worked perfectly well like serial port, usb etc..
I use a single static class in my code that defines a static field which I'm reusing between Activity onStop/onStart invocations. Here's a scenario:
User clicks on "Authorize" button (static data is initialized) Activity is stopped and web browser is called
Browser executes callback and Activity is restored (static data is reused)
At least one of my users reports the failure at step 3 which I cannot reproduce but which looks like reset of static data.
I am creating an Android application which will have some embedded music inside of it ( ~ 80 MB ). I was planning on putting it in the res/raw folder.
Since android stores that all in it's internal memory, is this way too large? What are my options? I have come up with the following:
Copy resources out of internal storage and onto the SD card when application first starts. Afterwards remove from internal storage (is this possible?)
Download music from the web when the application first starts.
I would really prefer not to have to go with option 2 since I want the app to be entirely offline and the static music is not going to change (except between releases).
As a first step toward a speech recognition project, we wrote a simple voice recording application based on the information in this thread:
http://groups.google.com/group/android-developers/browse_thread/threa...
It is working; however, the audio is extremely poor too static for our needs. As a comparison, we did a similar audio file captured with audacity on a PC and it was much better. Has anyone been able to record high quality audio with the android dev phone? According to the documentation of MediaRecorder, there is only one audio encoder "AMR (Narrowband) audio codec" and three output formats--3gpp, mpeg, and raw AMR:
http://developer.android.com/reference/android/media/MediaRecorder.html
According to wikipedia, AMR encoding is only 8hz. Is there a better option available perhaps a lower-level API compared to MediaRecorder? We are testing on Windows XP, with a Logitec USB microphone, eclipse ganymede, and we are using all the defaults for an android 1.5 app (no emulator command-line options. We defined the SD card in AVD manager).
When starting a new Activity, I want to pass a complex object and do so by using this approach:
MyActivity.COMPLEX_OBJ = myComplexObj; // which is definitely NOT NULL! Intent intent = new Intent(); intent.setClass(this, MyActivity.class); startActivity(intent);
and then in MyActivity:
@Override public void onCreate(Bundle bundle) { if (COMPLEX_OBJ == null) { // report to Flurry ... } ...
}
I 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?

View 12 Replies View RelatedWhy is the use of static final variables encouraged to declare constants over just final variables? The use of static sounds logical when there will be many instances of a class but is this argument correct when used for a Android activity. In fact, since the Class instance will be around even after the activity finishes and is eventually garbage collected, it seems like all these constants will still be in memory until the class loader is around. Also, does the compiler inline non-static final variables(ints and String) just like it does for static final variables?
View 2 Replies View RelatedI'm trying to handle exceptions at a global level. My understanding is that the only way to do this is with an UncaughtExceptionHandler. However, this reduces one to the primitive java file and network i/o packages. I'd like to be able to broadcast an intent or bind to a service. Is there some way to interact with the android packages to retrieve a context in a static manner? I could probably do some hack workaround with a thread local, weak-referenced context set at the time of the exception handler, but I'd rather avoid that nastiness.
View 4 Replies View RelatedI have a ListView with several columns and I need a header row at the very top that labels each of these columns that *does not* scroll with the rest of the ListView. I am using addHeaderView right now, but I've ran into 2 problems:
1) The header scrolls. I need it outside of scrolling so that it's always "floating" on top.
2) Each column in the header isn't lining up with the columns in the listview. I can make the header columns and data columns all line up perfectly if they're all in one big TableLayout, but how would I get the header to be outside of the scrollview yet also stay uniform and inline with the data columns?
In android, are using static variables a recommended practice?

Also, when does this get cleaned up by the Android JVM?
I use in the getView()-Method of this example a static function to download the source of an ImageView. Later there will be threading included. However, I like to know in general how save the use of static function is in this case.
Because I experienced, that in some cases (when I scroll really fast) the Images get mixed up.code...
My application crashes after I try to use the static Bitmap createBitmap method to get a mutable bitmap in order to fill it later with data.
If I only create one 1024x1024 the application works just fine, but when I try to load the same image more than once (first making my object null in each round) my application crashes on my third or fourth try.

I am currently developing a simple info app on various uni campuses. I want the app to operate predominantly in an offline state thus I want to store all my information locally. The data within the app will not be subject to any change thus I was wondering what the best (practice) method was to store such data? Basically should I be storing the info in a SQLite db, java file or xml?

My concern is i want to use this at work, but for this to be completly functional i need to put a static route into the system. We have a wireless network which is seperate from our wired by a router. It is all static IP based and so on to keep employess off the internet, but if you know what static route to put in you can access the systems on the wired network. Does anyone know if this is posible, i have tried looking at the system files via Astro and i havent found anything.
View 2 Replies View RelatedI've got a common use-case wherein a user selects one item out of many (say, on a spinner or autocomplete list), then enters the data. For example, let's say the user selects a country. Ultimately, the data I want is the country code, not the country name; but the users will want to select based on name, not code. To put it another way, user's will select "United States", but I ultimately want that to translate into "US".
There are a lot of countries. Is there an easy way to setup a mapping in Android to hash from the name to the code? I've thought of a few solutions, none of them are quite satisfactory in my mind:
A database containing country/code, which I can query on. Setting up all countries as strings in strings.xml, then retrieving the resource by name. Creating a huge Map in code and using that. (This is the least satisfactory answer).
