要解决Android中Metawear和MbientLab无法下载记录的数据的问题,可以按照以下步骤进行操作:
确保你已经在Android项目中正确集成了Metawear SDK和MbientLab库。可以参考相关文档或教程进行集成。
确认你已经连接到了Metawear设备。可以使用以下代码片段来连接到设备:
BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
BluetoothAdapter bluetoothAdapter = bluetoothManager.getAdapter();
BluetoothDevice device = bluetoothAdapter.getRemoteDevice(deviceAddress);
MetaWearBoard board = serviceBinder.getMetaWearBoard(device);
board.connectAsync().onComplete(new AsyncOperation.CompletionHandler() {
@Override
public void success(Void result) {
Log.i(TAG, "Connected to device");
}
@Override
public void failure(Throwable error) {
Log.e(TAG, "Connection failed: " + error.getMessage());
}
});
确保你将deviceAddress
替换为你的Metawear设备的蓝牙地址。
Logging logging = board.getModule(Logging.class);
logging.downloadAsync().onComplete(new AsyncOperation.CompletionHandler() {
@Override
public void success(Void result) {
Log.i(TAG, "Download completed");
}
@Override
public void failure(Throwable error) {
Log.e(TAG, "Download failed: " + error.getMessage());
}
});
这将下载所有可用的记录数据。你可以根据需要进行自定义配置,例如指定下载的时间范围等。
logging.setDownloadHandler(new Logging.DownloadHandler() {
@Override
public void onProgressUpdate(int nEntriesLeft, int totalEntries) {
Log.i(TAG, "Progress: " + nEntriesLeft + "/" + totalEntries);
}
@Override
public void receivedUnknownLogEntry(byte logId, Calendar timestamp, byte[] data) {
// 处理接收到的数据
}
@Override
public void receivedLogEntry(Logging.LogEntry entry) {
// 处理接收到的数据
}
});
在receivedUnknownLogEntry
和receivedLogEntry
方法中,你可以处理接收到的数据。可以根据需要进行解析、存储或显示。
这些步骤应该能够帮助你解决Android中Metawear和MbientLab无法下载记录数据的问题。记得将代码片段中的变量适当替换为你的项目中的变量。
