Solusi:

• Import support library sebagai project dari “android_sdk/extras/android/support/v7/appcompat”.
• Klik kanan pada appcompat_v7 project -> Build Project.
• Klik kanan pada project yg error -> Properties -> Android -> Scroll kebawah, pada bagian library -> Add… -> Pilih appcompat_v7 -> Ok -> Ok.
• Build Project.
• Jika masih error, coba clean kemudian rebuild project.
