In a layout file, it appears that you have a <linearlayout> tag. Please use a <LinearLayout> tag instead. Case is important here.

UPDATE: The original question had the layout files, but I missed them due to the formatting. As Squonk notes, all elements need to be in proper case.

@san1234 : Just because you fixed linearlayout by changing case to LinearLayout doesn't mean you've fixed your problem totally. Had it occured to you that button should be Button and textview should be TextView? Case-sensitivity applies to all widgets used in layout files as well as other XML files as it does with Java code files. – Squonk Dec 06 '14 at 21:46
@san1234: Then, by definition, you are crashing someplace else. Use LogCat to examine your **new** Java stack trace, and continue your debugging efforts. – CommonsWare Dec 06 '14 at 21:56
@san1234 : I just noticed this... `` - even if you changed case, that is wrong. The closing element of XML should be immediately after the main body of the element (unless nesting elements). You should put ` after the `` definition and attributes and `` after the `` *IS* allowed however as a `LinearLayout` is a `ViewGroup` and allows multiple widgets. – Squonk Dec 06 '14 at 22:01
