About Android 4.4 Camera preview, video screen problem solving method _android

System: LC android4.4

In the camera before and after the video, found that there will be a flower screen, but not necessarily, may occur after a reboot will appear, and will be in the necessary state, unless again restart.

Baidu has a lot of solutions, what by setting camera.unlock, and so on, are unable to solve, after the continuous attempt, the solution is as follows:

To set the preview resolution:

Camera.parameters Parameters = Camera.getparameters ();
Parameters.setpreviewsize (width, height);

Note: Here the width, height is set to unsupported values will crash. You can get a list of the resolutions that your camera supports by: parameters.getsupportedpreviewsizes (), and then see which resolution doesn't cause the screen.

Similarly, when recording the screen, also set the video resolution:

Mideorecord.setvideosize (width, height)
