What cause the Philippine American collaboration against spaniard?

There was no such collaboration. In 1896 the Philippine Revolution against Spain began, and in 1898 the United States declared war on Spain and invaded the Philippines. The Philippine revolutionaries formed an alliance with the United States, which agreed to recognize Philippine independence after the war. However, after the war, the United States reneged on its promise and instead annexed the Philippines as a colony.
