Currently I am trying to compile native code for Android. The code is from the OpenCV port for Android. I pasted all the code correctly in my project and edited my make files accordingly. When I set android:debuggable to false everything works fine and I get my native library. When I try while android:debuggable is set to true I get an error.
Here is a part of the log:
CODE:....................
From what I have found on the internet this is caused by the optimization level of the compilation. As long as the code isn't compiled so that is is debuggable afterwards everything should be fine.
Now apparently it is possible to avoid this by setting APP-OPTIM := release in the Application.mk or adding -O2 to LOCAL_CFLAGS. I have tried both and still I get this error.
Right now I don't really care that much about debugging my native code, but I would like to have basic debugging enabled. And I don't want to keep switching android:debuggable in my manifest every time I want to compile. I'm not even sure if it is okay at all if I just set android:debuggable to false pre compiling and to true post compiling, but I am sure I will forget it every second run.
My Android app runs fine, but: If I insert a call to WebView.setScrollbarFadingEnabled, it crashes saying:
Could not find method android.webkit.WebView.setScrollbarFadingEnabled, referenced from [my class]
VFY: unable to resolve virtual method 289: Landroid/webkit/WebView;.setScrollbarFadingEnabled (Z)V
I am using Android 1.5, not a custom ROM. My app defines minSdkVersion="3" I always clean before compiling.
Is setScrollbarFadingEnabled unavailable in Android 1.5? If so, why don't I receive a compiler error?
I've run into the following issue:
Say I have an Animal class, which is parcelable, and I have a Dog class and a Cat class, which are subclasses of Animal and also implement Parcelable.
Say I have a service with the following AIDL interface:
sendAnimals(List<Animal> animals);
Now I'm calling this remote interface from some client application, passing it a List containing Cats and Dogs. What happens now is that android calls the Cat's and the Dog's writeToParcel() methods at the client side, but at the server side, the Animal's CREATOR is used, which calls Animal's readFromParcel() method. So the right data is sent from the client, but the wrong unmarshalling code is executed at the server.
I have tried to put this in the AIDL file:
sendAnimals(List<T extends Animal> animals);
This results in a syntax error from the aidl compiler though.
My current workaround is as follows: - In each specific Animal subtype's writeToParcel() method, I write the class name as a String into the Parcel as the first element. - In the Animal's CREATOR.createFromParcel() I read the first String out of the parcel, and based on that I create the appropriate type and call the appropriate readFromParcel() method.
I think this is kind of ugly though. I would expect the android framework to take care of this for me.
(My application is not actually dealing with animals, this is just to make it simpler to explain the issue)

View 2 Replies View RelatedI see a lot of posts about writing to the SD card, but I believe my problem is different. I am unable to create the SD card during the process of building an AVD.
I initially tried to use the Android SDK and AVD Manager to do this, selecting
Name: my_avd
Target: Android 2.2 - API Level 8
SD Card: Size: 1024 MiB
Skin: Built-In: Default (HVGA)
Hardware: Property: Abstracted LCD Density, Value: 160
This pops up a window with the message:
"Result of creating AVD 'my_avd':
Error: Failed to create the SD card."
I tried to repeat the process from the command line, receiving a similar error:

Attempting to follow instructions for using mksdcard was equally unproductive; I think my basic lack of linux experience may be causing me a problem here. When I try to use mksdcard, it just reports that it cannot find the file or directory. Is the mksdcard tool available for use this way in linux?

I've added the android tools directory to my PATH variable, but I feel like there is obviously something else I'm missing. Perhaps some kind of access rights?
Attempting to run the android command with sudo did not seem to help either:

I am trying to download the android source onto a new ubuntu 8.10 installation on a x86 machine. All the steps worked fine until I tried to init the repo client. I get the following. I can't find anyone else having such an repo error. I did find an obscure message that said the python error might be due to a missing readline module. I tried to install lib32readline5-dev as in the download instructions and got the following error Any ideas anybody?

View 1 Replies View RelatedIs anyone able to explain to me exactly what the upcoming JIT compiler will provide? For example, I have Java programs that generate bytecode at runtime which I would like to port to android. Will the JIT compiler make this possible by converting the runtime generated Java byte code to Dalvik at runtime as required?
View 2 Replies View RelatedFor example, will this result in any performance gain:
-- public static final boolean DEV_MODE = false;
if(DEV_MODE){ // log stuff, compute debug values etc. }
I just read that Android has a 450% performance improvement because it added a JIT compiler, I know what JIT is, but I don't really understand why is it faster than normal compiled code? or what's the difference with the older approach from the Android platform (the Java like run compiled bytecode).
View 5 Replies View RelatedI'm using Eclipse with ADT to develop my project, but for some reason my AIDL files are not getting compiled into Java files. Is there a way to explicitly invoked the conversion of my AIDL files?
View 2 Replies View RelatedIs there a way to control the optimization level of the java compiler that Eclipse uses when building a project?Or is this question not relevant anymore, is all optimization deferred to the vm? The results of this tests imples test_f() is not being inlined, even though it really is a prime candidate for it. It should also be possible to do this inlining at compile time.I investigated this further, and it turns out Dalvik doesn't do inlining at this date.
View 1 Replies View RelatedIt is clear that cross compilers will not be allowed by the Apple App Store, so a developer will need to be familiar with Objective-C to create applications for the iPhone.I was wondering, is there a cross compiler that will take Objective-C application code and rebuild it into a similar Java application that can be packaged for Android? 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.

This is my first post and it should be an interesting one. Today I was trying to install Ubuntu on my rooted Galaxy S Vibrant. But, When I was moving the Contents of the download to my SD card, I realized that I didn't have enough space. I had a 2 gig SD card and the contents were just over 2 gigs (Plus the SD card really only had about 1.9 gigs) so obviously THAT wouldn't work. So I asked around and someone said that they had dropped the ubuntu contents into the internal memory instead of the SD card on their Moto DROID. Basically I am wondering if it is possible to do the installation process through my 16gb internal memory instead of the sd card. So for example in the guide telling you how to install ubuntu on android where it says to access the files for installation, they wouldn't be in the SD card, they would be in the internal memory.

To answer some preliminary questions:
- Yes, I have my phone on.
- It's on a USB 2.0 port.
- Yes, it sees the emulator(s), but not my device.
- Yes, "USB debugging" is enabled on the phone (and I tried toggling it).
- I've rebooted both the phone and the PC.
- I'm using the latest the 1.0_r2 SDK from the site.
- I'm on 64-bit Ubuntu, but it also fails to work in my 32-bit VM (that also previously worked)
During my very short time experience with Android, I found that Linux is most suitable environment for development compared to Windows. Please correct me if I'm too inexperienced. My question is, Which version of the Linux is best suitable. [Redhat/Fedora/Ubuntu..] Please let me know. Is Linux version really matters.
