    <p>I used <a href="https://stackoverflow.com/users/749709/walta">walta</a>'s solution but I had some problems with YUV conversion, camera frames output sizes and crash on camera release.</p> <p>Finally the following code worked for me:</p> <pre><code>public class MySurfaceView extends SurfaceView implements Callback, Camera.PreviewCallback { private static final String TAG = "MySurfaceView";

// } @Override public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { } @Override public void surfaceCreated(SurfaceHolder holder) { synchronized (this) { if (isPreviewRunning) return; this.setWillNotDraw(false); // This allows us to make our own draw calls to this canvas mCamera = Camera.open(); isPreviewRunning = true; Camera.Parameters p = mCamera.getParameters(); Size size = p.getPreviewSize(); width = size.width; height = size.height; p.setPreviewFormat(ImageFormat.NV21); showSupportedCameraFormats(p); mCamera.setParameters(p); rgbints = new int[width * height]; // try { mCamera.setPreviewDisplay(holder);

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
