kennydude / zxing-lib Goto Github PK

A sample app for this library would be fantastic. (of course, along with the usual suspects like a maven pom.xml and the addition of gradle files).

Maybe you could re-organize the project into

/
/library
/sample

Similar to https://github.com/JakeWharton/Android-ViewPagerIndicator/. Then see how to go from there. :)

how can i fix it ?

Hi,

Thanks for the work, it saved my days to redo the same thing.
Just saw in TODO a task of making the ViewfinderView display in the right position.
(I'm quite new to GitHub and don't know how to contribute - so I will put the code here)
CameraConfiguration.java
/**
* Reads, one time, values from the camera that are needed by the app.
*/
void initFromCameraParameters(Camera camera, int width, int height) {
Camera.Parameters parameters = camera.getParameters();
if (width == 0 || height == 0) {
WindowManager manager = (WindowManager) context
.getSystemService(Context.WINDOW_SERVICE);
Display display = manager.getDefaultDisplay();
initFromCameraParameters(camera, display.getWidth(), display.getHeight());
}

=> Allow the init method to take width,height
=> If either of them are 0 (not sure this is the best way) then use the Screen resolution.

CameraManager.java
public synchronized void openDriver(SurfaceHolder holder)
throws IOException {
Camera theCamera = camera;
if (theCamera == null) {
theCamera = new OpenCameraManager().build().open();
if (theCamera == null) {
throw new IOException();
}
camera = theCamera;
}
theCamera.setPreviewDisplay(holder);

    if (!initialized) {
        initialized = true;
        configManager.initFromCameraParameters(theCamera, 
                holder.getSurfaceFrame().right, 
                holder.getSurfaceFrame().bottom);

=> Pass in the size of holder into init method.

So far, it works perfectly on my side.
Hope this can save some other people time.

Cheers,
Chính

Hi all,
I using it the same "read me" file, when i build it and see:
"Missing artifact android.support:compatibility-v4:jar:11"
How to fix it?
Thanks so much!

I followed your documentation to integrate a zxing decoder into my default layout (new android 4.2 project). I built the library with maven and placed it into the lib folder of my new android project. After that i added the permissions for zxing functionality to manifest file (please add this to documentation). After starting the app on my device i get the following exception:

I have used http://stackoverflow.com/a/16252917/2553526 to allow portrait mode. But it takes too long(approx. 30 seconds) to scan CODE_39. Sometimes it misread the VIN number.
Can you point out my mistake? It would be so helpful.
Thanks

In class DecodeHandler, method renderCroppedGreyscaleBitmap() is undifined

Hey,

the deployment to Maven Central is described here:

https://docs.sonatype.org/display/Repository/Uploading+3rd-party+Artifacts+to+The+Central+Repository
