I was trying so long for Camera2 api integration to my app.Its working fine for capturing image at first.But when i snap second time the preview was not coming.I tested it in genymotion nexus 5 emulator.Tried with all examples.Preview was not coming for snapping at second time.Getting this error also. java.lang.IllegalArgumentException: Surface had no valid native Surface...
and i followed this 2 codes http://inducesmile.com/android/android-camera2-api-example-tutorial/?cid=519 Github-Camera2Master.Please help anyone to resolve this error and give some links for more detailed explanation about camera 2 api

I've seen this issue before and its because the thread being used by the Camera is no longer alive. Debugging the Camera API you'll see that it uses Handlers to invoke the necessary functions. The culprit for sending message to a Handler on a dead thread is right here:
@Override
protected void onPause() {
Log.e(TAG, "onPause");
//closeCamera();
stopBackgroundThread();
super.onPause();
}
Your onPause() is killing the thread that is being used by the CameraAPI which is causing that error message. That's not the real issue, but instead the LegacyCameraDevice_nativeGetSurfaceId: Could not retrieve native Surface from surface.The Camera2 API will complain a lot if the surfaces are not configured to the right params. Since you're using the example, perhaps you should initialize and configure the TextureView just like the sample you linked. I know they extend the class and provide a helper method to configure, might take care of this problem.
As a side note, you should invoke super before doing your own thing.

I figured out two reasons for this error on my side:
1) For Video I selected CamcorderProfile.QUALITY_HIGH which is not always supported by the MediaRecorder so I have to check both:
profileHQ = CamcorderProfile.get(Integer.parseInt(cameraDevice.getId()),
CamcorderProfile.QUALITY_HIGH);
foreach (Size size : cameraConfig.getOutputSizes(MediaRecorder.class))
if (size.getHeight() == profileHQ.videoFrameHeight && size.getWidth() == profileHQ.videoFrameWidth) {
// you may use this profile
}
2) For Image capturing I had one phone which can collect huge images (5248x3936) which took so long that the next image capturing request interrupted the first: The thread was closed which lead to the surface being unavailable. Now, I wait until the image was saved before I take the next picture:
@Override
public void onImageAvailable(ImageReader reader) {
Image image = null;
try {
image = reader.acquireLatestImage();
ByteBuffer buffer = image.getPlanes()[0].getBuffer();
byte[] bytes = new byte[buffer.capacity()];
buffer.get(bytes);
save(bytes);
} catch (IOException e) {
throw new IllegalStateException("Unable to write image to buffer.", e);
} finally {
if (image != null) {
image.close();
}
try {
LOGGER.debug("Taking next picture ...");
if (!closeRequestReceived) takePicture();
} catch (CameraAccessException e) {
e.printStackTrace();
}
}
}
