Android :: How To Add Includes In Native C Code That Will Be Compiled By Ndk

Aug 23, 2010

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.

Android :: How To Make Sure An App Really Compiled From Said Source Code

Jun 24, 2010

A lot of Android apps are open source, but how can we make sure the person who finally uploads to the Google Market does not include some spyware just before uploading?

Background: Mobile apps security seems to be a growing concern, and I would like to reassure the users of my Open Source Android app. Solutions that require to modify the deployment process or application content are acceptable too.

Android :: JavaScript Code After App Is Compiled Using Titanium Mobile

Nov 18, 2010

I installed Titanium from appcelerator and built the "KitchenSink" example application.All works well, I'm just wondering where does the javascript code ends up in a built app.I grep-ed the Xcode project and also the result application as I found it in Library/Application Support/iPhone Simulator/KitchenSink.app, but I can't find any function names from .js files, not even string texts used within the application. Nearest information I found is an answer here : How Does Appcelerator Titanium Mobile Work? but I do not understand clearly how the process works.Is the javascript code being compiled into a binary code (what compiler is used then?), or is it just transformed in some special data-format and interpreted in a running application ?

Android :: Can Use TraceView In Native Code When Using NDK

Dec 10, 2009

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?

Android :: Using Surface In The Native Code

Feb 3, 2010

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.

Android :: Debugging Native Code (C++) Using Gdb With Eclipse / Is It Possible?

May 24, 2010

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?

Android :: Can Native Only Code Run As Standalone Application

Nov 8, 2010

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?

Android :: Porting JMF / Native Source Code

Jan 22, 2009

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?

Android :: Print Backtrace When Debug Native Code

Nov 23, 2010

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++?

Android :: Debugging Integrated Java And Native Code

Feb 7, 2009

I am trying to figure out what is the best way to debug a mix of Java and native code? Please notice, that I am NOT trying to develop a native app. The app will be written entirely in Java, using Android SDK. However, I noticed that some pieces of the SDK use native methods (e.g. AssetManager, WebKit, etc). I wonder which tools Google developers use if/when they need to debug a mix of Java and C/C++ code? Eclipse/gdb or there are commercial tools which make the debugging experience less painful?

Android :: How To Play Synthesized Sounds? (Native Code)

Oct 9, 2010

I wrote an iPhone app some time ago that creates sound programatically. It uses an AudioQueue to generate sound. With the AudioQueue, I can register for a callback whenever the system needs sound, and respond by filling a buffer with raw audio data. The buffers are small, so the sound can respond to user inputs with reasonably low latency.

I'd like to do a similar app on Android, but I'm not sure how. The MediaPlayer and SoundPool classes seems to be for playing canned media from files, which is not what I need. The JetPlayer appears to be some sort of MIDI playback engine. Is there an equivalent to AudioQueue in the Android Java API? Do I have to use native code to accomplish what I want?

Android :: Way To View Phone Native Code Profiling?

Mar 29, 2010

I started my emulator with ./emulator -trace profile -avd emulator_15. I then tracked down the trace files to ~/.android/avd/rodgers_emulator_15.avd/traces/profile, where there are six files: qtrace.bb, qtrace.exc, qtrace.insn, qtrace.method, qtrace.pid, qtrace.static. I can't figure out what to do with these files. I've tried both dmtracedump and traceview on all of the files, but none seem to generate any output I can do anything with.

How can I view the proportion of time taken by native method calls on Android?

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.

Android :: Particular Version Of Droid Source Code / Unable To Install Apps With Native

Sep 17, 2009

I've synced my android repository just after android sdk 1.6 announced, but found some problem to install my apps with native code (so built by NDK 1.5_r1) then.

I tried to build NDK with the latest source code, bu unfortunately, faile again :( .

So is there any way to get particular version of android source code? for example the android-1.5r3 tag. Would be great if some command like "svn switch /foo/bar/1.5r3" is available.
