[0027] In system / vold / VolumeManager.cpp of the Android source code.
[0028] Add the processing of these events in the VolumeManger receiving event processing function. The specific location of adding code is in the handleBlockEvent function of VolumeManager.
[0029] VolumeManager::handleBlockEvent(evt) {
[0030] for(it=mVolumes->begin();it!=mVolumes->end();++it) {
[0031] …
[0032] hit = true;
[0033] break;
[0034]}
[0035] if (!hit) { / / Do not store device node information in the mVolume list,
[0036] ... / / Follow-up processin...
