    mStorageManager = StorageManager.from(this);
    final StorageVolume[] storageVolumes = mStorageManager.getVolumeList();
    for (StorageVolume volume : storageVolumes) {
        if (!volume.isEmulated()) {
    

            }
        }
    }

U盘设备状态和路径

import android.os.storage.StorageManager;
import android.os.storage.StorageEventListener;
private StorageManager mStorageManager;


 mStorageManager = StorageManager.from(this);
 

//注册和反注册

mStorageManager.registerListener(mStorageListener);


if (mStorageManager != null && mStorageListener != null) {
    mStorageManager.unregisterListener(mStorageListener);
}


    /**
     *
     * 监听  path  路径    oldState 上一个状态      newState 当前状态
     *  所有状态 mounted   unmounted     removed     checking
     */
    StorageEventListener mStorageListener = new StorageEventListener() {
        @Override
        public void onStorageStateChanged(String path, String oldState, String newState) {
            Log.i("qkmin -voolesettings"," StorageEventListener Received storage state changed notification that " + path +
                    " changed state from " + oldState + " to " + newState);
