Not natively supported in manual mode. Workaround: Use a ImageReader with YUV_420_888 format for preview + separate capture request on shutter click. 5. Performance Optimization | Optimization | Method | |--------------|--------| | Reduce latency | Use CameraDevice.TEMPLATE_ZERO_SHUTTER_LAG when possible | | Memory | Reuse ImageReader surfaces; avoid per-frame allocations | | Preview FPS | Set CaptureRequest.CONTROL_AE_TARGET_FPS_RANGE | | RAW capture | Process DNG off main thread; use DngCreator efficiently | 6. Testing and Results We tested the Camera 2 APK on three devices:
| Device | API Level | Manual ISO | Long Exposure (≥2s) | RAW Support | |--------|-----------|------------|---------------------|--------------| | Pixel 6 | 31 | Full range | Yes | Yes | | Galaxy S21 | 30 | Limited (100–800) | Yes | Yes | | Moto G9 | 29 | No manual ISO | No | No |
