  We study the questions of how supersymmetry is spontaneously broken in Anti
de-Sitter spacetime. We verify that the would-be R-symmetry in $AdS_4$ plays a
central role for the existence of meta-stable supersymmetry breaking. To
illustrate, some well-known models such as Poloyni models and O'Raifeartaigh
models are investigated in detail. Our calculations are reliable in flat
spacetime limit and confirm us that meta-stable vacua are generic even though
quantum corrections are taken into account.
