I want to use somthing like: MyLogger.e("MyApp","I have an error.");
In a cross-plattform project, where MyLogger should be static to make it available in the whole project.
So I was trying something like:
CODE:.........
The compiler complains about the static. How do I do this? Is it possible at all? If not, what's the right approach?

So I have trying to access this website
JavaCamperCam
But it does not stream the video. When I click zoom it states the Java Applet is downloading but nothing ever happens are the video is never displayed.
What do I have to do to see the video? Or is it not even possible to view?

I need compiling a lib (ODE) for android - problem is it uses automake and I can't seem to find any decent documentation/how to cross compile a static/dynamic lib for android.
BTW, I'm using ubuntu 12.04 as a dev environment (latest up-to-datest SDK and NDKs are installed) and I have no problem with making the wrapper library - just need to get the static (or dynamic) lib built.
We have a desktop/web java application and also getting into Android development.Ideally we would like one app that runs both on desktop and android.From what we can tell, it's not much possible to run normal java apps on android. But wondering if it can do it the other way? That is, run android apps easily on the desktop (without the user install the sdk or android emulator)?In a prefect world we'd like one app for both platforms. Realistically though it seems like we're going to have to have one app with two front ends?

That way, a developer could still learn just one language (obj-c) but put out applications on many devices.I understand that the Java port would be less optimal than a natively coded application, but could conceivably save a developer some time.

For example I have the following method:
CODE:.................
In my Android app, I need to call a non static java method from C/C++. But i get a blunt crash when i do it using GetMethodID/CallVoidMethod()1 methods.
I have done like this:
1. Register the method using GetMethodID() as follows (mine is a cpp file): jmethodID xyz = (env)->GetMethodID( cls, "showxyz", "()V");
2. And I call this method as follows: env->CallVoidMethod(cls, xyz);
3. In java, my showxyz() is defined this way(this basically enables a button which was disabled) void showxyz() {findViewById(R.id.btnPass).setEnabled(true);}
And this crashes.
But I have been using this method of calling Java funcs from C using a set of GetStaticMethodID/CallStaticVoidMethod()(for nonstatic methods) and that works always.
But in this case, I have to call a non-static method and i get a crash.
I have some C++ code that I want to make into a static lib for use with Java on the Android platform. Can anyone point me to a resource that tells me how to do this? I am completely new to Java and Android.

I am having a static method .In the method when I decalare a variable , it was showing an error in eclipse saying that the variable should be decalared as final.
Can I know the reason for this , y should a variable in a static method be declared as final? I am writng an Android application where I should pass as an argument current Context of that application. So, when I pass the current context to the method and trying to copy it in a local variable , I am getting this error saying that the variable should be declared as final.
My method is like this:

Error is showing at line where Context myctx=ctx; is declared and asking me to declare it as final.
I have an existing C++ library that I want to compile into a static library, and call commands from it with Java on the Android platform. I am brand new to Android development, and just need to figure out how to set the Java interface up so my C++ lib works on the Android. Where do I start?

I set up my Eclipse as it is described on http://source.android.com/using-eclipse.
But how can I run the Email app on my device? An "run as..." on the source folder miss the Android simulator. When I use the Email sources to build a Android project, it miss a lot of dependencies.
I have the latest version of Eclipse, Google Android SDK, Subclipse (not sure if that's relevant) and Google App Engine plugin.
While trying to work on an Android project, I ALWAYS get the following error:
"The applet is attempting to access the file "isFile" state attributes..."
Plus 3 buttons: Allow, Disallow and Stop applet.
It keeps popping this message, sometimes 10-20 times in a row until it leaves me alone. Then on the next file save, update or changes to the project, it shows the message again.
Here's a screenshot:

i want to display a msg to the user (msg box or Toast) when exception happend in a static SQLite Database class that i use. the problem is that i cant call a non static method in a static class , how can i handle this. this is the class
private static SQLiteDatabase getDatabase(Context aContext) {
and i want to add something like this in the class when exception happen but context generates the problem of reference to non static in static class.
Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
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:

And then calling control.setActivity(this); from my onResume section of DemoActivity.java!

Is there an app available to log a GPS track that can later be exported and synced to the pictures from my real camera?I had an app like this for my BB, and would like to maintain the functionality on my Droid.
View 2 Replies View RelatedI'm creating a datalogger which logs the gps data and the sensor data of the phone. I've just a strange problem. If the phone is not touched for few minutes it goes into standby mode (screen goes black), and that causes the logger to stop working. Actually the firewriting in the logger stops working. The GPS resumes fine after coming out of blackscreen, but when I check the log I created it only shows saved points for few minutes. Does anyone have idea what is causing this?
View 1 Replies View RelatedI 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
Is there an app that notifies me the user about that my jelly bean phone has just crashed, with the exact time and date and is also logging in a database, so I can look it up later? Is there an app like that?
My phone, ever since moving to cyanogenmod 10.1 (considered stable) is rebooting randomly pretty much every day. Sometimes, during the night it might be even doing this without me knowing. I want to calculate a stability index (also for other OS) based on the run time and the crashes (unwanted restarts) that the OS is doing. If the crash frequency goes over a certain threshold, the user can be warned that his OS is unstable and unreliable at the moment and that she should not rely on it.
I want to be able to use encryption again, but cannot if I want to be able to use the alarm clock and depend on it waking me up.
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.

Does anyone know of an open-source OpenCellID logger for Android? We wish to contribute to opencellid.org in our products. We wish to integrate such a logger into it - so closed source code isn't an alternative.
