Android :: Internal Compiler Error When Compiling Native Code
Aug 9, 2010
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.

For example, will this result in any performance gain:
-- public static final boolean DEV_MODE = false;
if(DEV_MODE){ // log stuff, compute debug values etc. }

The following code was copied from one project to another. No errors in project one.
In project 2 I get:
-The method onClick(View) of type new View.OnClickListener((){} must override a superclass method
-implements androd.view.View.OnClickListener.onClick

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)

I want to compile my application with full android source code. Its because If I compile it alone then I need different library with it and so .apk size will increase. So please tell me in which make file or configuration file should I do the change. I have placed my application inside ..mydroid/package/app . My application is developed in Eclipse and is compilable in eclipse.If there is other way by which .apk size can kept smaller please elaborate. Your help is highly appreciated.

I can't figure out which library or object file I'm missing that would resolve this reference. Btw, I've tried building it a couple ways: typical "brunch", and lunch / mka. Both produce the same error.

Some classes are NOT PUBLIC like android.os.ServiceManager, android.view.IWindowManager, etc, they are implemented in the mobile devices, but not present in the SDK .jar. This is because these classes are private APIs . now please tell me is there any way like compiling source code or importing private class file into android.jar so that i can use this private APIs.

We know that it's very convenient to use TraceView in Android java code to check the runtime of different chunks of code. Now I develop my app with NDK and I want to check the runtime of some native functions, but I found nothing in TraceView guide if it's possible to use this tool. Because I noticed that one of my native methods spent too much time and I want to dig out the more detailed root cause. Is there anybody know if we can use TraceView in native code?

I am planning to write a video player application and I am planning to use the gstreamer on the native side. I am trying to use the SurfaceFlinger for the rendering part. For this I have written a test program to experiment on the rendering part. I am using the surface flinger wrapper from the project
http://gitorious.org/rowboat/external-gst-plugins-android
But the following ERROR occurs when we try to run the .apk.
CODE:.......
The I changed the permission for "android.permission.ACCESS_SURFACE_FLINGER" in frameworks/base/core/ res/AndroidManifest.xml to "dangerous" and recompiled. But got the same error.
Then I commented out the "checkCallingPermission" method in IServiceManager.cpp and recompiled. Then also i got the same error.

Is this possible to access a sensor data form native code without using Java at all? I need to access to the sensor as fast as possible, but it seems like the "DELAY_FASTEST" parameter when registering an event change is not fast enough.

I set out to use SkCanvas and other native SKIA classes but I could not find any sample code. After a week's of search and diving deep into Android source, I got it working.

I have some piece of code which uses JNI. I can debug code wrote in Java directly in Eclipse (using ADT). I even have a script, which help me debug native code with gdb. However this is not very comfortable way for doing this.Is it possible to configure Eclipse to use gdb (I guess gdbserver) for debbuging android native applications? Do you know where I could find any description of this?

We want to migrate a huge complex native program to Android system ,running it as a background service accepting command sent from Java Program using JNI along with IPC. However, the Android NDK state following words:
Please note that the NDK does not enable you to develop native-only applications. Android's primary runtime remains the Dalvik virtual machine.
Does that mean we have no way to run an standalone native-only application on Android as a background service? The native code can only exist in the form of library that will be loaded to the virtual machine through JNI?

I am creating an Android application which uses the JMF (SIP, RTP, JAIN). So i downloaded the JMF source code for some adhoc change to my application.The basic questions 1. How will it behave the "native files - C/C++/header" in JMF source files(downloaded)? because android is based on java right now. 2. Is there any complete different way to porting/doing the SIP, RTP working in android?Is there any link from sun.com(this) site for JMF source code?Any suggestion and comment about this?

How I can add headers to my native c file.
So here's the details.
I was able to setup my android project to call a native function from a .so file. And actually I need to add box2d to my project, but I when I include the header files, it won't make. So basically my problem is how do I tell the make file to include a whole folder with header and cpp files.
I tried adding the path directly to the include statement just for the sake of testing it. The error goes away, but new errors come out.

When I debug android app, if I work with Java, I can use Log.d("TAG", "xxxx", new Throwable()) to print backtrace of Java code. This is really handy for me to find bugs. But when I work with native library (e.g. libwebcore.so), there seems no way to print backtrace in runtime. The only way to debug native code is use gdbserver.
I have a question: Is there any way to print backtrace in C/C++?

Try to select (or update) from custom databases (for example mmssms.db) but on init I see " Unable to open the database file". Try send permissions in manifest <uses-permission android:name="android.permission.WRITE_SMS"/> <uses-permission android:name="android.permission.READ_SMS"/> but this doesn't help.
