[android-developers] Re: Performance issue executing native code on ICS
We met exactly the same issue! We are on ICS 4.0.4 with Nexus S. Will google plan to fix it in the next release say 4.0.5?

Note that the exact behavior even changes with different build targets; ~30% of CPU time are already bad when building against Android 2.3.3, but it gets a lot worse with ~45% when building against Android 4.0.3.

It's not an active face detection - we double-checked that. A quick look through the Android source code didn't give any insight either. Though my suspicion is that either something is wrong with the ICS implementation or the camera driver. It would be nice to get more info on that, and potential solutions to fix the issue. You could try and see if you can get git to give up a diff of the relevant files in mediaserver between the two versions of Android, but that may be a lengthy path to follow. It would be interesting if you could reproduce the same difference in mediaserver CPU usage with someone else's code that doesn't do any (even dummy) native processing. Could you try the CamerPreview in the ApiDemos of the sdk samples? If you can reproduce the mediaserver CPU load reflected by top with that you'd clearly be in a position to file a bug report. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How to wait for file scanning finished before starting the launcher app
Hi there I am currently working on an Android launcher application, and I would like to play some intro video before the launcher starts. Knowing that playing video directly from assets or raw folder does not work on some devices, I include the video file in assets folder, and let the app copy the video file to SD card before playing it. However, since launcher is always the first application to be started upon bootup, there is a media scanning process right after the bootup. So the problem is when the launcher is started, the SD card file system may still being scanned and not ready to be accessed, therefore the video cannot be played. Any suggestions and comments are appreciated! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Alternative of VMRuntime.getRuntime().setMinimumHeapSize in Gingerbread

[android-developers] How to set focus on the item in Gallery view when activity is started
Hi, I am developing an application that is navigated by DPad, and I use gallery view as the navigation bar. How do I set the initial focus to be on the central item of the gallery view? I know that some control like EditText can attract the focus, but I still have no luck after trying gallery.requestFocus() or gallery.requestFocusFromTouch(). Really appreciate if someone can help me out, thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How to broadcast information with Bluetooth on Android?
I'd like to know how to broadcast information with Bluetooth on Android. I'm thinking to utilize the service name for SDP record in listenUsingRfcommWithServiceRecord() to broadcast the information. However, I couldn't find any method to use to read the service name for SDP record. May I know is there any way to read that? Or is there any other more appropriate approach to broadcast information with Bluetooth? Plz enlighten me. Ur help would be greatly appreciated. =) -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Eclair install choked with errors about locks and died horribly leaving corrupted install
I'm new to this group. Has anyone got an answer to the problem? I read through the posts and I can say I've tried most of the way I can think of. First of all, I'm pretty sure it's 'SDK Setup.exe' that is locking up the directory. So after it unpacks the platforms and addons to 'temp' directory, it can't move the subdirs under 'temp' to 'platforms' and 'add-ons'. I confirmed the lock because I couldn't delete any directory when 'SDK Setup' was running. Manually, you CAN move the subdirs under 'temp' yourself by following error log telling you failed to move directory from temp... to platforms The problem is the subdirs under 'temp' are empty directories. So your manual tasks will be done in vain. I tried 3 times! I tried to trick 'SDK Setup' by moving to Windows DeskTop. But it wouldn't run from there! Sigh. I tried to install it from eclipse. Same error. There must be an easier way to install the Android SDK 1.6 or 2.0. The previous versions that have pre-expanded directories work fine. So you just unzip the file and drap-and-drop the whole folder to wherever you want. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Playing video as a raw resource
I have the exact problem with you. Any one can help? On Jun 16, 11:22 pm, JP jpotte...@gmail.com wrote: I'm writing a program which requires that a video be packaged with it. The only way I know of doing this is by adding the video to res/ raw/, which coincidentally renders the video useless. I've looked all over the web and the consensus seems to be you can only play streaming video, or video from a file. In the emulator if I attempt to play the video through the method used here (http://developer.android.com/guide/topics/media/index.html ), all I get is audio and a black screen. I've attempted to use VideoView as well, and the same thing occurs, audio but with a black screen. There must be a way to package video with your application without needing an SD card, or having to stream the file and have the video actually play. In the words of Google, I would like to create a seamless experience. :) Any help is greatly appreciated! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How does prelink-linux-arm.map work?
Hi, I got some diopen() fails in my native library. I guess the reason is insufficient memory. I conduct some experiments by exhausting the memory and then dynamically load some .so files. Yes, dlopen() failed again. At first I thought the .so files listed in prelink-linux-arm.map are libraries pre-loaded into memory, and dlopen won't fail if the target is in the map. However, that's not true. Anybody here knows what's the use of the map? Or where did I go wrong? Thanks.
