AIR Packaging APK With Native Libs?
Nov 1, 2011
My team is currently trying to package a native .so library within an AIR APK. This native library is used by a native extension we've built, but the library is not the extension itself, therefore the standard process of creating an AIR APK with an extension does not include these libraries. We have to, somehow, instruct AIR to include the native libs in the packaging process.
The real headache is that for Android to link to these libraries, it appears that they must sit in the following directories (we have 2 .so files):
/lib
/armeabi
mynativelib.so
/armeabi-v7a
mynativelib.so
When using ADT we can include the /lib directory in the APK, but AIR sticks the /lib directory in the APK's /assets directory with the rest of the AIR files....but this does not work because Android does not appear to find the native libs.
how we can get this lib directory sitting at the root of the APK?

I want to add functionality to an app to easily apply filters and such to images. Examples for the kinds of filters/effect I am looking for are Dithering, Blur, Black & White, Gray Scale, Invert Color, etc.
know any frameworks/libs that provide this functionality to be easily used in an App? Or a source that lists frameworks for Android.
I was only able to find a list of Android Libraries provided by OpenIntents.

I've noticed that the PNGs of my application with some gradients effects looked terribly bad at the device (a Samsung Galaxy) and at the emulator, and I've found the following note at the documentation (http://developer.android.com/guide/topics/graphics/2d- graphics.html):
Image resources placed in res/drawable/ may be automatically optimized with lossless image compression by the aapt tool. For example, a true-color PNG that does not require more than 256 colors may be converted to an 8-bit PNG with a color palette. This will result in an image of equal quality but which requires less memory. So be aware that the image binaries placed in this directory can change during the build. If you plan on reading an image as a bit stream in order to convert it to a bitmap, put your images in the res/raw/ folder instead, where they will not be optimized."
I've tried the res/raw suggestion, but it didn't worked.
I've tried to use the image as JPEG as a workaround, but I couldn't use 9-patch.
I've uploaded a comparison between the original png and the "optimized" png that is shown on the emulator or devices: [url]
One workaround would be put the images at /assets/ and manually load and set the image on the ImageViews, but it requires a lot of code changes.

I've got ~200 png files in the /res/drawable folder, mostly interface and sprite sheet stuff. They're all indexed pngs, and weigh in at a grand total of a bit over 400kb.
When I run aapt to package them into the apk, their filesize nearly doubles. Opening the apk up with 7zip and extracting the drawables confirms it: 790kb.
Does anyone have any idea why this would be happening? I thought the packaging process was meant to compress the pngs, not inflate them!

I'm placing the file '.nomedia' into a folder in order to avoid Android's MediaScanner from detecting the media files in the folder. I need to copy this folder (including '.nomedia') from the APK's assets to the SD card (so other apps can make use of these media files, etc.). When I package the APK in Eclipse, it doesn't package the '.nomedia' file. Presumably it's detecting it as a hidden file. Any ideas how to fix this? Is there a secret aapt flag I can use? I'd like to avoid copying the folder and then manually creating a '.nomedia' folder, if possible.

In Windows, we write "installer script", and user an "installer compiler" to generate an installer, let's say .inf for .msi/.cab and .nsi for NSIS.
But when it comes to Android, is there a similar method?

If I create an application for Android, how do you package extra items in with it like a live wallpaper or widgets? For example, google maps does this by including a live wallpaper with the download of the latest version.
On a related note, with google maps, it's available for, I believe, 1.6 and up, but it seems that it is all the same download. So how do you ensure that, even though there may be a 2.x only feature included, it still shows up for lower OS phones? Or is the marketplace maybe actually holding onto two separate APKs for each OS?

I am getting an error in my Problems tab for my Android Project in Eclipse. The error is "Android Packaging Problem" with an Unknown location. Unknown Error NullPointerException
I cannot determine what this problem is. My project was working a few hours ago. The only change I made was to add a public interface ITrackDao to my project and implement it. There are no errors associated with this. I am not even sure where to begin to look. I cannot launch the application.

I'm getting this crazy error on multiple projects, even when I revert back to prior versions that compiled just fine. Unknown Error - java.lang.NullPointerException Android Packaging Problem Path is blank Location is Unknown. 1 - Project -> Clean -> All 2 - Deleting .metadata folder 3 - reimporting projects into the eclipse 4 - reverting my projects back to prior working versions using git. I just can't get anything to compile now, and I've searched for solutions here and on eclipse forums.

There are some apps like the NASCAR one that I will never need. Is it a problem to kill apps that are pre-installed on the EVO using ATK or one of the file/task manager apps? Any apps I should not kill for stability reasons?

I've seen a lot of remarks about good call recorder apps for the EVO 4G. None of them are really that good or reliable.
To take advantage of native call recording on the EVO 4G, all you need to do is set the phone call to speaker after connected and then start the Voice Recorder app that comes with the phone. It records both sides of the conversation very clearly and you can adjust the speaker volume to about 75% for optimum audio capturing.
In the state of Texas, it is legal to record any conversation without informing the other party that you are doing so. Be sure to check with your state before recording any phone calls covertly.

I'm just looking at the Android's native IM app and wondering if it's possible to create new providers? I know other people have written seperate IM clients but it'd be great to add to list in the native IM app.
The 3 I'd like to work on is Facebook, MySpaceIM, Skype.

I need to take pictures with my application, but the only thing I am finding are examples of how to create a camera activity. Is there a way I can call up the phones native camera instead and get the byte[] data back instead of creating a camera activity myself?
I am asking because I would like to take advantage of the normal features like zoom, flash, themes, etc that the user would get if they push the camera button on their phone.

I'm wondering what the limitations are if we develop the app using Titanium.
What cannot be done using Titanium, for iPhone and for Android?
What things can only be done using only the the native tools?

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.
