For Faster process of Blur Image I want to use below function

StackBlurManager stackBlurManager = new StackBlurManager(bitmapFromGalleryOrCamera);
stackBlurManager.processNatively(25);

whenever I use above method .processNatively I am getting following errror
java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/packageName-1/base.apk"],nativeLibraryDirectories=[/data/app/[packageName-1/lib/arm, /vendor/lib, /system/lib]]] couldn't find "libblur.so"

So I have decided that I need to compile StackBlur module with NDK

but whenever I compile your StackBlur module with ndk-build I am getting following error

Android NDK: WARNING: APP_PLATFORM android-19 is larger than android:minSdkVersion 8 in /..//..//../StackBlur/AndroidManifest.xml    
Android NDK: ERROR:/..//.../StackBlur/jni/Android.mk:rsjni: LOCAL_SRC_FILES points to a missing file    
Android NDK: Check that /..//..../StackBlur/jni/arm64-v8a/librsjni.so exists  or that its path is corret

Please suggest me what is the issue? what should I need to do to resolve this

I had a problem when I use Robolectric tests. Two of my test use this library but sometimes one of them works and sometimes any works.

Gradle:
compile 'com.commit451:NativeStackBlur:1.0.2'

Here is my code:

imageLoader.displayImage(urlImage, imageTitulo, options, new ImageLoadingListener() {
            @Override
            public void onLoadingStarted(String s, View view) {}
            @Override
            public void onLoadingFailed(String s, View view, FailReason failReason) {}
            @Override
            public void onLoadingComplete(String s, View view, Bitmap bitmap) {
                Bitmap bm = NativeStackBlur.process(bitmap, 10);
                imageTitulo.setImageBitmap(bm);
                imageStreetV.setImageBitmap(bitmap);
            }
            @Override
            public void onLoadingCancelled(String s, View view) {}
        });

And here is the output:

The App works as well but the tests failed, I don't know why they failed just sometimes.

Thanks!

The defaut build-tools target is 18.1.0, but "RenderScript support mode requires Build-Tools 19.0.3 or later." appears in my Concole window.
So I change target "18.1.0" to "19.0.3" in project.properties ,and the error disappeared. Another error ,however,occur when I try to run "StackBlurDemo" as a android project.
The message is as follow:
[2015-02-05 17:25:11 - Dex Loader] Unable to execute dex: Multiple dex files define Landroid/support/v8/renderscript/Allocation$1;
[2015-02-05 17:25:11 - StackBlurDemo] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Landroid/support/v8/renderscript/Allocation$1;
What is the problem?I don't understand it.

SurfaceView is not supported on many libs.They just get a bitmap by activity cutting ,then they blur this bitmap. However it is not work on SurfaceView.Others get blur bitmap by root phone. Google's api can do this,but it need some Athority.

when I clean the library using the eclipse ,some errors appear in file blur.rs。
like this:
error: Non-root compute kernel blur_v() is not supported in SDK levels 11-15
warning: implicit declaration of function 'rsSetElementAt_uchar4' is invalid in C99
error: Non-root compute kernel blur_h() is not supported in SDK levels 11-15

someone can help me ,thanks very much！

Please find the logs.

Have you ever considered adding support for MLKit Selfie segmentation?
That way we could build apps that only blur the background in a fast way, for video calls for example.
In this case, the processNatively function would accept the com.google.mlkit.vision.segmentation.SegmentationMask as a parameter and return an image that has its background blurred based on the mask.

use native methon,the picture exit border line

Hello, I´m getting a rare error in runtime, I´ve compiled the NDK successfully and the StackBlur (library project) compiles well, but when I reference the project library in a totally new Android Application Project something is interfering with the R Class of the new project, it compiles well but when call findviewById(R.id.textView1) returns null, I've tested the Android Project before reference the library and without it findviewById(R.id.textView1) works normally.

I´ve looking around and the people getting this error agree it is something weird with the R Class, but nobody found a really stright solution.

Can you help me with this error, please?

I really want to try this awesome blur effect with the ndk implementation.

Hi,
I get an "AndroidBitmap_lockPixels() failed ! error=-3" randomly
with "Fatal signal 11 (SIGSEGV) at 0x41609c6c (code=2), thread 15102 (pool-2-thread-3)"
I tried to catch this error but no way for the moment ?
Is there a solution ?

Thank you.

when i call stackBlurManager.process(5), error occurs：

I thought that it is a problem of roboguice, but regular findViewById() also always returns null. I have no idea what can be causing this problem, I tried cleaning the project many times with no luck. Referencing the library in another project also causes this problem. Any advice will be appreciated.

I've included the StackBlur library in my project but the processRenderScript method doesn't work. When I call it I get a NoSuchField error. I'm not sure whether it helps but in StackBlur/gen/R/raw I can see a value for blur, but under my project /gen/R/raw there are no fields. Maybe it's not being carried through?

Here's the stack trace:

How to blur Bitmap with color?

I build the .so files with ndk-build and they can be found under Stackblur/libs.

If I now build the app with gradle the app crashes with this Exception:

Eclipse show an error after i import the project :

Download the library with git. When it has been imported into your project. First initialize your StackBlurManager to load a sample image

Could you provide more info on how to import this into android studio?. THanks

Awesome work:-)
I wonder is it possible to quick tweak the process(int radius) method, reduce to difference between two levels
so the seekbar can act smoother?

Hi,

Thank you for this great lib, the java version is working very well, but I tried the native version and I got a libc﹕Fatal signal 11 (SIGSEGV) at 0x62448000 (code=2), thread 30186 (AsyncTask #3), which makes the app the shutdown immediately.

I'm really new to the NDK, from what I understand with Google it could be anything, so I'm not asking for a solution but I'm trying to see if I missed something. :)

• I made sure the native code is only running in one thread, so it's not a concurrent access problem.
• I can see the native logs in the logcat: Image size is: 640 680, so far so good…
• I've put some logs in the loops of the algorithm, and from what I can see, the crash is occuring at random points during the algorithm. If I put "return;" at the beginning of the native function the app doesn't crash (but no blur, of course).

Do you have any pointer on this? I run the code in an AsyncTask, is it wrong?

Thank you for your time and keep up the good work!

Hi,

I have to change the buildToolsVersion of stackblur to "19.0.3" to build success. Any body have idea why its doesn't work with "19.0.1".

Thanks.

In RSBlurProcess.java we can not found ScriptC_blur.

It would be nice to have the library uploaded to maven central, and just import it via gradle!

Thanks mate!

Hi,

I believe the following code is causing my app to crash on some devices:

StackBlurManager stackBlurManager = new StackBlurManager(normalBitmap);
blurredBitmap = stackBlurManager.processNatively(100);

I can't know for sure because native crashes do not provide any stack trace but there is just this one place in my code where I'm calling the method processNatively().

I'm not sure if it helps but here is the backtrace provided:
#00 pc 0000156a /data/app-lib/.../libblur.so (stackblurJob+1713)
#1 pc 00001b1d /data/app-lib/.../libblur.so (Java_com_enrique_stackblur_NativeBlurProcess_functionToBlur+96)
#2 pc 00158a64 /data/dalvik-cache/data@app@[email protected]

This crash seems to happen regardless of API level (my app runs on 4.0+) or device. I get one crash report roughly every 2 days.

Any ideas on how I can debug this or at least catch the crash somehow?

Thank you,
Ricardo

The Garbage Collector is being run (GC_FOR_MALLOC) on every blur because we're creating a new bitmap on every call. There's two ways to try to fix this.

Explicit Bitmap Re-use

The usual solution to this problem is to allow the user to pass an existing bitmap in.

StackBlurManager manager = new StackBlurManager(bitmap);
Bitmap output = Bitmap.createBitmap(
    bitmap.getWidth(),
    bitmap.getHeight,
    Bitmap.Config.ARGB_8888
);
manager.process(10, output);

Pros

• No possible breaking changes with existing code
• The user gets to choose if they need to recycle the bitmap

Cons

• Most uses could benefit from recycling, but the user has to explicitly do so

Implicit Bitmap Re-use

However, because we have the StackBlurManager class which already holds a reference to the result, we could possibly reuse that bitmap. This could possibly break some existing code though! If the user holds on to a reference to the blurred bitmap, then blurs again, the first reference will be modified to be the same as the second. For example:

StackBlurManager manager = new StackBlurManager(bitmap);
Bitmap blur5px = manager.process(5);
Bitmap blur10px = manager.process(10);
// blur5px and blur10px are the same Bitmap, and both are blurred by 10px.
// The user would have to explicitly copy the bitmap if they want control of it.
Bitmap correct_blur5px = manager.process(5).copy(Bitmap.Config.ARGB_8888, false);

Another possible problem arises if the user tries to recycle the image.

StackBlurManager manager = new StackBlurManager(bitmap);
Bitmap tmp = manager.process(5);
tmp.recycle();
// User thinks they're cleaning up after themselves, but the bitmap is
// owned by the StackBlurManager.

The StackBlurManager can check if the image has been recycled before trying to blur into it, and make a new bitmap if it has been, possibly putting something in the log letting the user know they shouldn't call recycle on bitmaps owned by the manager.

Pros

• Bitmaps are automatically recycled, using the existing _result variable in the StackBlurManager

Cons

• Possible code breakage

when I import stackblur to eclipse,every thing is ok,but there are some error report by eclipse.I don't know if other people have encountered.My problem is:
First,eclipse report three errors in the file StackBlur/src/blur.rs.

2.warning: implicit declaration of function 'rsSetElementAt_uchar4' is invalid in C99

3.error: Non-root compute kernel blur_h() is not supported in SDK levels 11-15

Second,can't find class "ScriptC_blur" in RSBlurProcess.java file.

And i saw that it pass param R.raw.blur ,but the file res/raw/blur is not exists in the project.

Last,the project structure is

Can anyone give some help? Thanks very much!

When I try to run my app on Nexus 9 with NativeStackBlur dependency, I get the following exception:

UNCAUGHT EXCEPTION (main). Force logging out.:
java.lang.Exception: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/BLA.dev-2/base.apk"],nativeLibraryDirectories=[/data/app/BLA.dev-2/lib/arm64, /vendor/lib64, /system/lib64]]] couldn't find "library.so"
...

...

The app does work on other (non 64-bit) devices.

Hate to say that but compile failure in Android studio 1.0

There isn't a straightforward way to use this on Jetpack Compose yet. Could it be possible to provide a Composable component that can use the stackblur library? Thank you!

if (!alpha)
alpha = (int)(Color.alpha(originalPixels[y*_height+x])) != 255;

The renderscriptTargetApi is set to 19 but should be 18 to support older devices.

I'm using ormlite in the app and when i import stack blur the application stops responding.
