Take Video is directing to gallery and toasting that file should be less than 10 mb.

Whenever I click on Take Video or Take Picture it directs me to gallery, like the choose picture. I couldn't find what was wrong with my code.

public static final int TAKE_VIDEO_REQUEST = 1;
public static final int PICK_PHOTO_REQUEST = 2;
public static final int PICK_VIDEO_REQUEST = 3;

public static final int MEDIA_TYPE_IMAGE = 4;
public static final int MEDIA_TYPE_VIDEO = 5;

public static final int FILE_SIZE_LIMIT = 1024*1024*10;
