As official documentation says:

The minimal platform supported by OpenCV Java API is Android 2.2 (API 8)

armeabi, armv7a-neon, arm7a-neon-android8, mips and x86 stand for platform targets:

• armeabi is for ARM v5 and ARM v6 architectures with Android API 8+,
• armv7a-neon is for NEON-optimized ARM v7 with Android API 9+,
• arm7a-neon-android8 is for NEON-optimized ARM v7 with Android API 8,
• mips is for MIPS architecture with Android API 9+, x86 is for Intel
• x86 CPUs with Android API 9+.
