I'm currently developing a software under android and im getting quite quickly some OutOfMemoryException.... I did modified some part of my code to use more static variables instead of making new allocation with the "new" operator but is there any things else to do ? or any other tips ? Any advices would be welcome.

View 1 Replies View RelatedWhat I'm trying to do is this: I want my application to download an image from the Internet and save it to the phone's internal memory in a location that is private to the application. If there is no image available for the list item (i.e. it can't be found on the Internet), I want a default placeholder image to display. This is the image that I have defined in my list_item_row.xml file as the default.
In my ListActivity file, I am calling an instance of a CustomCursorAdapter class I have written. It is in CustomCursorAdapter where I am iterating through all the list items and defining what content needs to be mapped to the views, including the image file by trying to read it from internal memory.
I've seen several questions on this subject, but the examples either are specific to external phone memory (e.g. SDCard), involve saving strings instead of images, or involve using Bitmap.CompressFormat to reduce the resolution of the file (which is unnecessary in my case, as these images will be small thumbnails of already-small resolution). Trying to piece together code from each example has been difficult, hence my asking about my specific example.
At the moment, I believe I've written valid code, but no image is displaying for my list items, including the default placeholder image. I don't know if the problem is being caused by invalid download/save code, or invalid read code - it doesn't help that I don't know how to check internal memory to see if the image exists.Anyways, here's my code...
I wanted to check whether there is any JAVA Coding standards in Android platform for performance improvements.
For Example, like an Effective Java code in J2EE environment is to defined the number of elements in the ArrayList constructor rather leaving it blank (new ArrayList(noOfRows)) etc. I definetly suspect these performance tuning tips should be available because of the memory and resource constraints.

View 5 Replies View RelatedI have an application I am writing for Android that basically does a screen scrape of a large table on the web and presents it in a nicer way on the handset. Its 500k of html and takes about 20 seconds or so normally.
When I have my phone hooked up to the computer, I used to be able to just click on "Run" and my code would execute similiarly speedy, as opposed to Debug where it would take 10 minutes to complete.
Now, however, clicking "run" behaves just like debug mode.... I don't want this overhead, how do I get eclipse to stop sending my app to the debugger already? I have searched online and found a couple people with the same issue, but simply rebooting my phone doesn't fix it, and there have been no other solutions posted that I have found.
can some one plz help all my downloads are saving to my xperia mini pro and not my 16gb memory card any ideas how to change this?
View 9 Replies View RelatedI'm a .NET developer starting to dig into an android application. One thing that seems a little abstract is working with SqlLite. In a .NET application, I can do my Database setup, query testing and profiling, and enter in some test records through Management Studio for MSSQL. In fact, I'm constantly in Management Studio checking something - so I'm finding it difficult to work without a similar tool.
What are some good tools/tricks to use when developing SQLLite on Android? The tool doesn't have to have a GUI, but would be nice if I could run it as a desktop app and have it look at the same DB as my emulator.
For instance, something that will allow me to run a simple SELECT statement against a table to view records without having to do it through android?

I'm testing some layouts in a project using eclipse, and I'm following the guidelines from a textbook (beginning android 2.0) and I'm getting some rather perplexing errors. The first error is in my main.xml. my code is as follows:

View 5 Replies View RelatedLet me first state that I do not know Java. I'm a .NET developer with solid C# skills, but I'm actually attempting to learn Java and the Android SDK at the same time (I know it's probably not ideal, but oh well, I'm adventurous :)) That said, my end goal is to write a streaming media player for Android that can accept Windows Media streams. I'm okay with restricting myself to Android 2.0 and greater if I need to. My current device is a Motorola Droid running Android 2.0.1. There is one online radio service I listen to religiously on my PC that only offers Windows Media streaming, and I'd like to transcode the stream so my Android device can play it.
Is such a thing possible? If so, would it be feasible (i.e., would it be too CPU intensive and kill the battery)? Should I be looking into doing this with the NDK in native code instead of Java? I'm not opposed to writing some sort of service in between that runs on a desktop computer (even in C#), but ideally I'd like to explore purely device-based options first. Where should I start?
I keep hearing that Android applications should try to limit the number of objects created in order to reduce the workload on the garbage collector. It makes sense that you may not want to created massive numbers of objects to track on a limited memory footprint, for example on a traditional server application created 100,000 objects within a few seconds would not be unheard of.
The problem is how far should I take this? I've seen tons of examples of Android applications relying on static state in order supposedly "speed things up". Does increasing the number of instances that need to be garbage collected from dozens to hundreds really make that big of a difference? I can imagine changing my coding style to now created hundreds of thousands of objects like you might have on a full-blown Java-EE server but relying on a bunch of static state to (supposedly) reduce the number of objects to be garbage collected seems odd.
How much is it really necessary to change your coding style in order to create performance Android apps?

This is a recent install of the Android SDK. I just bought a Mac so even though I've previously done all my testing on a PC (and everything works fine there), I had to set up my mac for development. Installed latest version of Android SDK Installed Eclipse Helios and Android ADT. Now I really don't think this is a Helios or ADT issue since I can do all this without starting Eclipse at all using command line to start Emulator and using geo fix commands, and I get the same problem.

View 5 Replies View RelatedAfter spending the better half of this day getting my HTC Magic to work in developer mode, I've now found that some of my frist openGL coding attempts that appeared to work fine in the emulator doesn't work as expected on the device. I've narrowed this down to glColorf(r, g, b, a) not working as expected on the device itself. The provided OpenGL samples do work though. So for example, after modifying Cube.java from the samples to the below code I find that I get the expected grey square on the emulator but a blank white screen (background fill colour) on the device.
class Cube { public Cube() { int one = 0x10000; int vertices[] = { -one, -one, -one, one, one, -one, one, one, };
// Buffers to be passed to gl*Pointer() functions // must be direct, i.e., they must be placed on the // native heap where the garbage collector cannot // move them. // // Buffers with multi-byte datatypes (e.g., short, int, float) // must have their byte order set to native order
ByteBuffer vbb = ByteBuffer.allocateDirect(vertices.length*4); vbb.order(ByteOrder.nativeOrder()); mVertexBuffer = vbb.asIntBuffer(); mVertexBuffer.put(vertices); mVertexBuffer.position(0); }
public void draw(GL10 gl) { gl.glFrontFace(GL10.GL_CW); gl.glVertexPointer(2, gl.GL_FIXED, 0, mVertexBuffer); gl.glColor4f(0.5f, 0.5f, 0.5f, 0.5f); gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, 4); }
private IntBuffer mVertexBuffer;
