getExternalSdCardDetails()的cordova-diagnostic-plugin方法可用于获取可移动微型SD卡位置的参考：

cordova.plugins.diagnostic.getExternalSdCardDetails(function(details){
    details.forEach(function(detail){
        if(type === "application"){
            console.log("Writable?" + detail.canWrite); //TRUE
            cordova.file.externalSdCardApplicationStorageDirectory = detail.filePath; 
            // Write files to external SD card using this
        }else{ // type === "root"
            console.log("Writable?" + detail.canWrite); //FALSE
            cordova.file.externalSdCardRootDirectory = detail.filePath;
            // Read files from external SD card root using this
        }
    });
}, function(error){
    console.error(error);
});
