I have error while take screenshot on surface. After a lot of pictures, this error is made (it comes with the device), but the application does not stop.
After a lot of pictures, this method is no longer working. Do you have an idea about how to solve problems?

// Create a handler thread to offload the processing of the image.

Log.d("MyData", bitmap.toString());

I have seen the same error when using PixelCopy to grab the contents of a SurfaceView continuously (ie. for video transmission). I saw this effect only on Android 7.0 devices.
I attribute this to a memory leak that was present in Readback.cpp which, if I'm not wrong, is what PixelCopy uses internally.

This fix was added on September 1st 2016, while Android 7.0 was released August 22nd 2016,

If you are displaying images try eliminating them to see of it fixes the error.
It did for me and I ended up changing my image loading from:
mainMenu_viewHolder.getImageView().setImageResource(R.drawable.gear);
to...
Bitmap checkImg = BitmapFactory.decodeResource(fragment.getResources(), R.drawable.check);
mainMenu_viewHolder.getImageView().setImageBitmap(checkImg);
The issue is buried very deep so if this doesn't work for you don't try stepping through your code or researching the native error. It will be wasted time. Just disable your fragments entire view structure and add back in piece by piece.
I'm using webcam capture to get a webcam image in Java via the following code:
Webcam webcam = Webcam.getWebcamByName("VF0415 Live! Cam Vid. IM Ultra 1"); // USB webcam
webcam.open();
BufferedImage image = webcam.getImage();
ImageIO.write(image, "JPG", new File("test.jpg"));
Unfortunately, I get a timeout with the following error:
[main] INFO com.github.sarxos.webcam.Webcam - WebcamDefaultDriver capture driver will be used

I've looked through related issues on GitHub, and I've tried keeping my USB power on and intercepting the OS signals, but the error messages remain the same, giving me an essentially black image, as shown here:
Is there anything else I can try to fix this?
I am developing a prototype app, utilizing the tango depth camera for template matching. So far, I have been able to solve all problems with the help of already answered questions, documentation etc.
However, now I seem to have come to a stop. Last major change I made, was to draw a contour on the camera preview image, before displaying it. No matter what I do now, the app works for a while, before it crashes.
I have looked at heap dumps and allocation tracking in Android Studio. The only possibly weird thing there is that there can be a lot of memory on FinalizerReference objects in the heap dump...
I also tried moving the processing to an AsyncTask, and just skip every color frame until the task was done (so that only one task was running at a time) and the processed frame was displayed, but the problem remained.
I am using Google Tango for getting color and depth camera data and opencv in java for analyzing the data and doing the template matching.
Does someone have a clue of what these logcat messages mean?

Code for displaying camera preview:
mTango.experimentalConnectOnFrameListener(TangoCameraIntrinsics.TANGO_CAMERA_COLOR, new Tango.OnFrameAvailableListener() {
byte[] imageByteArray = new byte[colorCameraIntrinsics.height * colorCameraIntrinsics.width * 3 / 2];
Mat yuvMat = new Mat( colorCameraIntrinsics.height + colorCameraIntrinsics.height/2, colorCameraIntrinsics.width, CvType.CV_8UC1 );
Bitmap bitmapDisplay = Bitmap.createBitmap( colorCameraIntrinsics.width, colorCameraIntrinsics.height, Bitmap.Config.ARGB_8888 );
Mat colorMatDisplay;
#Override
public void onFrameAvailable(TangoImageBuffer imageBuffer, int cameraId) {
Log.d(TAG, "onFrameAvailable: color frame available");
if (colorFrameCounter < 3) { //only use every 3rd frame
Log.d(TAG, "onFrameAvailable: skipping frame " + colorFrameCounter);
colorFrameCounter++;
} else {
colorFrameCounter = 0;
if (!stopCameraView.get()) { // Only view frame if camera view is not stopped
// convert image buffer data to byte array
imageBuffer.data.get(imageByteArray);
// byte array to Mat object with YUV coding (NV21)
yuvMat.put(0, 0, imageByteArray);
// locking access to lastColorFrameMat
synchronized (lockVar) {
Log.d(TAG, "onFrameAvailable: converting to bitmap");
// convert from YUV (NV21) Mat to RGBA Mat and place in lastColorFrameMat (global)
Imgproc.cvtColor(yuvMat, lastColorFrameMat, Imgproc.COLOR_YUV2RGBA_NV21, 4);
colorMatDisplay = lastColorFrameMat.clone();
}
if (templateContours != null) {
Imgproc.drawContours(colorMatDisplay, templateContours, templateContourMaxIdx, new Scalar(0, 255, 0, 255), 5);
}
// convert colorMatDisplay to bitmap, for display in imageview
Utils.matToBitmap(colorMatDisplay, bitmapDisplay);
Log.d(TAG, "onFrameAvailable: view lastColorFrameMat on phone display");
// View colorImage in imageViewer on UI thread
runOnUiThread(new Runnable() {
#Override
public void run() {
imageViewer.setImageBitmap(bitmapDisplay);
}
});
}
}
}
});
There are two things potentially happened here:
the buffer for camera image went out of scope.
With current Tango's SDK, the callee of onFrameAvailable callback only have control to imageBuffer within the scope of the callback. That means if you reference imageBuffer in an AsynTask, you could potentially get a null buffer, and result in a crash. The way Tango solve it is to always deep copy out the data from the callback, and process it in another thread.
the process is blocking Tango's thread for too long.
Without the AsyncTask, what's likely happened is that the processing blocked Tango's thread for too long, and this is know to be bad for Tango as well.
I am using a custom camera to record Videos on android.
The device experiencing the issue is a Nexus 5 with Android 6.0.1 on it.
When the camera finishes recording for only for the 2nd time, i get the following exception in the under-the-hood android media AudioTrack class. This is something that is called implicitly by android, by the FinalizerDaemon, and not as a result of any code I execute directly. So the FinalizerDaemon calls finalize on AudioTrack, and gets an IllegalStateException.

Perhaps I need to do some sort of clean up when the camera finishes recording? Here's the current code I'm using when the recording stops:
#Override
public void stopRecording(boolean wasCancelled, float duration) {
if (mMediaRecorder != null) {
mMediaRecorder.stop();
mMediaRecorder.reset();
if (flashState) {
toggleFlash();
}
if (!wasCancelled) {
callbacks.onFinishedRecording(null, mediaPath, duration, wasCancelled);
}
}
}
mMediaRecorder is an instance of MediaRecorder class.
Any suggestions?
So I think this might be an Android bug. Looks suspiciously like this issue, which is marked as fixed in a "future version": https://issuetracker.google.com/issues/37138597
Same Issue Reported in Android 7.1.2
fixed in Android 8.0 https://android.googlesource.com/platform/frameworks/base/+log/aee6ee94675d56e71a42d52b16b8d8e5fa6ea3ff/media/java/android/media/PlayerBase.java
I'm developing a live wallpaper in android with opengl es 2.0. Started code is enter link description here. I want to reload textures on onSurfaceChanged method of renderer linked to wallpaper (and GLSurfaceView). On my Nexus 7 (2012) with tegra 3, when i try to do this, sometimes i obtain the following error:
08-11 03:54:41.128: D/NvOsDebugPrintf(26131): NvRmChannelSubmit: NvError_IoctlFailed with error code 1
08-11 03:54:41.130: D/NvOsDebugPrintf(26131): NvRmChannelSubmit failed (err = 1, SyncPointValue = 19952985, returning = 0)
08-11 03:54:41.130: D/NvOsDebugPrintf(26131): NvRmChannelSubmit failed (err = 196623, SyncPointValue = 0)
Is anybody got the same problem?
