我将文件从磨损发送到手持设备。我发送了4个或5个文件（其中2个更大），但每次手持端只收到一个较大的文件...
磨损：
public void sendFile(String filename){
//BLE files
fileToArray("BLEdata/" + filename + "_RightDevice.txt", "/BLEdata/");
//send log file
fileToArray(filename + "_LOG.txt", "/LOGdata/");
//send GPS file
fileToArray("GPSdata/" + filename + "_GPS.txt", "/GPSdata/");
//send Report files
fileToArray("Report/" + filename + "_Report.txt", "/REPORTdata/");
//BLE files
fileToArray("BLEdata/" + filename + "_LeftDevice.txt", "/BLEdata/");
}
public void fileToArray(String filename, String path)
{
FileInputStream fileInputStream = null;
File file = new File(Environment.getExternalStorageDirectory() + "/TuneWear/" + filename);
System.out.println("PATH: " + file.getPath());
if(file.exists()){
byte[] bFile = new byte[(int) file.length()];
try {
//convert file into array of bytes
fileInputStream = new FileInputStream(file);
fileInputStream.read(bFile);
fileInputStream.close();
WearResultsActivity main = (WearResultsActivity) getActivity();
long time = main.getInitTime();
if(filename.contains("_RightDevice")){
new SendToDataLayerThread(path + time, bFile, 2).start();
}else if (filename.contains("_LeftDevice")){
new SendToDataLayerThread(path + time, bFile, 1).start();
} else
new SendToDataLayerThread(path + time, bFile).start();
}catch(Exception e){
e.printStackTrace();
}
} else System.out.println("Doesn't exist:\n" + file.getPath());
}
class SendToDataLayerThread extends Thread {
String path;
byte[] bFile;
int footSide;
// Constructor for sending data objects to the data layer
SendToDataLayerThread(String p, byte[] bytes, int footside) {
path = p;
bFile = bytes;
footSide = footside;
}
SendToDataLayerThread(String p, byte[] bytes) {
path = p;
bFile = bytes;
}
public void run() {
WearResultsActivity main = (WearResultsActivity) getActivity();
GoogleApiClient googleClient = main.getGoogleClient();
Asset asset = Asset.createFromBytes(bFile);
System.out.println(asset.toString());
PutDataMapRequest dataMap = PutDataMapRequest.create(path);
dataMap.getDataMap().putLong("timestamp", Calendar.getInstance().getTimeInMillis());
dataMap.getDataMap().putLong("/InitialTime", ((WearResultsActivity) getActivity()).getInitTime());
dataMap.getDataMap().putAsset("asset", asset);
if(footSide == 1) {
dataMap.getDataMap().putInt("footside", footSide);
System.out.println("DATAMAP COM LEFT " + footSide);
}else if (footSide == 2) {
dataMap.getDataMap().putInt("footside", footSide);
System.out.println("DATAMAP COM RIGHT " + footSide);
}
PutDataRequest request = dataMap.asPutDataRequest();
PendingResult<DataApi.DataItemResult> pendingResult = Wearable.DataApi.putDataItem(googleClient, request);
pendingResult.setResultCallback(new ResultCallback<DataApi.DataItemResult>() {
@Override

}
});
//Wearable.DataApi.putDataItem(googleClient, request);
}
}

我每次只收到GPS，报告和LOG数据。其他两个文件我只收到一个...我发送它们的方式完全相同，但我只收到其中一个。 有没有人检测到我的代码错误???
修改 我刚刚发现，如果智能手表在发送文件时连接到掌上电脑，则会全部收到。如果它们没有连接，则在连接时不会收到其中一个文件（RightDevice.txt或LeftDevice.txt）...
答案 0 :(得分：1)
我解决了！
这是所有人中最基本的错误....我正在为两个文件（RightDevice和LeftDevice）发送相同的路径，因此只有一个对象在googleapiclient上更新。
