After React Native Android rebuild, external images no longer show in Android

After I rebuilt my android folder (some settings got corrupted) images will not work (using Image React Native component). I'm not sure what the issue could be. Here is an error I'm getting:
E/MediaHTTPConnection: java.io.IOException: Canceled

To reiterate: I haven't changed the Image code at all. I think some deps auto-updated during the rebuild. It seems to be an okttp issue.

Is there a way to run helgrind/drd in android?

I try to figure out some problem caused by thread sync in mips android, I installed valgrind in my mips machine, It is ok when using memcheck, but when I changed the option to --tool=helgrind, logcat says this:
I/start_valgrind.sh( 9328): link_image[2207]: 9329 could not load needed library '/data/local/Inst/lib/valgrind/vgpreload_drd-mips32-linux.so' for '/system/bin/app_process' (mips_relocate_got[1749]: 9329 cannot locate 'sched_yield'...
I located sched_yield in /system/lib/libc.so, but I can't find a way to add it to the link path; I using valgrind-3.10.0 and my android system version is 4.1.
So is it possible to run helgrind/drd in android? Thanks!

Integrate GeckoView in Android

I'm facing problem in file upload in webview in Kitkat(4.4).
As per https://code.google.com/p/android/issues/detail?id=62220 it can't be done in 4.4 due to missing method in new version of webview.
Hence searched and found GeckoView(https://wiki.mozilla.org/Mobile/GeckoView) as alternative for webview.
I followed all steps specified at https://wiki.mozilla.org/Mobile/GeckoView, still project is not running in emulator as well as android device.
I tried downloading and importing sample project Geckobrowser in https://wiki.mozilla.org/Mobile/GeckoView, but it gives compile time error for getCurrentBrowser() method.
I'm using Windows OS. Can anyone please guide me through, not able to know what i'm missing. I'll really great-full for any lead in correct direction.

You must check cpu abi version, and change geckoview_library and geckoview_asset to match the abi.
http://ftp.mozilla.org/pub/mozilla.org/mobile/nightly/
From the link, you can download several kinds of geckoview library.
This is a sample.
[DIR] latest-mozilla-central-android-armv6/ 12-Dec-2013 11:50 -
[DIR] latest-mozilla-central-android-r7/ 12-Dec-2013 11:56 -
[DIR] latest-mozilla-central-android-x86/ 12-Dec-2013 11:56 -
[DIR] latest-mozilla-central-android/ 12-Dec-2013 11:56 -
In each folder, download geckoview_library and geckoview_asset.

Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 655 (Thread-77)

I'm developing an application for Android using cocos2d-x. I'm new to cocos2d-x and C++ and I'm on windows, I have followed due process from creating the Cocos2d-x project template for Eclipse to importing the project into Eclipse and adding c++ features to it etc... I succesfully got my app to run in the emulator(target API 4.1) and it gives me the cocos2d "HelloWorld Splash" as expected. Problem is, now I'm trying to change my Application background image. I added an image in the assets directory and changed the code in "HelloWorldScene.cpp" that creates the default HelloWorld Sprite
from:
CCSprite* pSprite = CCSprite::create("HelloWorld.png");
to:
CCSprite* pSprite = CCSprite::create("background.jpg");
Once I do the latter, my emulator crashes after trying to run the App and in logcat I get the error "Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1)", but if I put back the default HelloWorld.png it runs again smoothly in the emulator.
I use cocos2d-2.0-rc2-x-2.0.1 and android-ndk-r8b. This App runs only on a 4.1 API device emulator, I can't get it to run on 2.3.3 and 4.3 as it crashes while trying to run. Please, kindly help me out please

I think you might forget to run the build_native.sh script to update the libgame.so

Stick to png image format.
Make sure that your image is copied to
assets directory on android project.(This happens automatically if
you have the image in Resources directory).

Try troubleshooting your image.
Take the "HelloWorld.png" and modify it in whatever image editor you use. If it works then you know it's not your editor.
Try making your background image the same size as "HelloWorld.png" and in PNG format with the same default settings as "HelloWorld.png"
Also ensure that the "HelloWorld.png" is in your Assets directory, if not you may need to add the Assets directory to the search path via CCFileUtils
Good Luck!

Unforunately OpenCV Manager has stopped in OpenCV 2.4.3 for android 4.2 ( Mac OSX 10.7)

I have a problem running openCV samples project (3 - 4). Everytime that I run the program, I found the problem "Unforunately OpenCV Manager has stopped" displays in my Android emulator.
The problem occurs everytime that I call
OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, this, mLoaderCallback);
I followed this page
http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/dev_with_OCV_on_Android.html
This is the Warning Message that I have
/Applications/eclipse-android/android-ndk-r8c/toolchains/arm-linux-androideabi-4.6/prebuilt/darwin-x86/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld:

Logcat (from OpenCV sample4):

Note:
I set java compliance level to 1.6 since I have some problem compiling OpenCV c++ file.
(followed this page: 'Must Override a Superclass Method' Errors after importing a project into Eclipse)
I install adb with both OpenCV_2.4.3_binary_pack_armv7a.apk and OpenCV_2.4.3_Manager_2.0_armeabi-v7a.apk
I used Samsung Galaxy S as my cellphone emulator

I run into the same problem:
hidden symbol '__aeabi_atexit' armeabi-v7a/libgnustl_static.a(atexit_arm.o) is referenced by DSO
I am using the opencv test in jni, with an application that worked before I have added it.
I have tried to change the ARMv7-A machine to armeabi in the "Application.mk'
I have also tried to add all the paths mentioned above to the Project -> Properties -> C/C++ General -> Path and Symbols.
It didn't work.
Thanks to my team leader, I have found the solution:
in Application.mk, You need to change the APP_STL := gnustl_static
to APP_STL := gnustl_shared. This is because the lib apparantly was compiled in shared instead of static.
In addition, add to the loadlibrary area the lib: System.loadLibrary("gnustl_shared");
This should be done in a static area, as followed:
static {
try{
System.loadLibrary("gnustl_shared");
//To do - add your static code
}
catch(UnsatisfiedLinkError e) {
Log.v(TAG, "Native code library failed to load.\n" + e);
}
catch(Exception e) {
Log.v(TAG, "Exception: " + e);
}
}
That's it! it solved my problem...
Hope it helped.

Your problem might simply be emulator itself, try to get an actually device to test on.
There are a lot of things that emulator can't handle.

If you use Android 4.2 than change to 4.0.3 or to 4.1. There is a bug about that: http://code.opencv.org/issues/2537

I had problems this days running the two tutorials too.
On my machine I installed OpenCV 2.4.3, Android-sdk-21 and Android-ndk-r8c, Eclipse Juno. I perform my tests on an Asus Transformer tf101g running Android 4.0.3.
When I ran the tutorials it failed with a strange ClassNotFoundException. Checking the project properties I realized that the two projects look for headers in a wrong place. Go to Project -> Properties -> C/C++ General -> Path and Symbols. Here you can see the include directories used in the jni file.
The NDKROOT environment variable was not set in my system and I had to manually set it to point to the NDK root folder.
Then I had to change the stl include from
${NDKROOT}/sources/cxx-stl/gnu-libstdc++/include
to
${NDKROOT}/sources/cxx-stl/gnu-libstdc++/4.6/include
Hope this can help.

I too struggled with this for almost 4 hours, including downgrading target to 4.0.3 but did not work.
The solution was to download the latest openCV manager from google play to your device directly.

I got the same error and thought even though late,the solution might help for some in future.
The error "Unforunately OpenCV Manager has stopped" pops up if its version is not supported by the android device hardware(like armeabi-v7a (ARMv7-A + NEON) or Intel x86,etc). uninstall the current Manager and install the proper one.

Paste the following code before onCreate() Method:
static {
System.loadLibrary("opencv_java3");
}
it worked for me.
