本文介绍了一段用于格式化和卸载SD卡的Java代码实现。通过Android系统的IMountService接口，可以调用formatMedia和unmountMedia方法来完成SD卡的格式化和卸载操作。

private IMountService mMountService; mMountService = getMountService(); private synchronized IMountService getMountService() { if (mMountService == null) { IBinder service = ServiceManager.getService("mount"); if (service != null) { mMountService = IMountService.Stub.asInterface(service); } else { Log.e(TAG, "Can't get mount service"); } } return mMountService; } //format sdcard mMountService.formatMedia(Environment.getExternalStorageDirectory().toString()); //unmount sdcard mMountService.unmountMedia(Environment.getExternalStorageDirectory().toString());
