如果捕获的图像等于或大于（3264x2448），为什么会发生异常？图像＆lt; 3264x2448还可以。
public void surfaceCreated(SurfaceHolder holder) {
// The Surface has been created, now tell the camera where to draw the
// preview.
try {
mCamera.setPreviewDisplay(holder);
mCamera.startPreview();
} catch (IOException e) {
Log.d("DEBUG", "Error setting camera preview: " + e.getMessage());
}
}
功能错误：
public void surfaceDestroyed(SurfaceHolder holder) {
try {
// Non camera related code
// Start of camera related code
// Only clean up what you need to
if (mCamera != null) {
mCamera.cancelAutoFocus();
mCamera.stopPreview();
}
} catch (RuntimeException e) {
e.printStackTrace();
} finally {
// Make sure that at least these two calls are made
mCamera.release();
mCamera = null;
}
}
