Accessing the SensorDump API - Android -


has worked on sensordump android app before? i'm trying accelerometer values phone , i've been able dump in csv file on computer. however, i'd add timestamp values , sensordump doesn't provide that.

i can't find documentation online ,and wondering if had tried modify it, or if there's other app out there same (i.e. lets me write sensor values onto file, timestamp).

thanks!

i wrote own sensor dumper, in activity in oncreate:

    mstarttime = systemclock.uptimemillis()         try {                     f = new filewriter("/sdcard/download/sensorlog.txt");                     if (f != null) {                         f.append("time;value0;value1;value2\r\n");                     }         } catch (ioexception e1) {         log.e(tag, "cannot open sensorlog file..");     }   msensormanager = (sensormanager) this.getsystemservice(context.sensor_service);     msteplistener = new sensoreventlistener() {     @override         public void onaccuracychanged(sensor arg0, int arg1) {           }          @override         public void onsensorchanged(sensorevent event) {              sensor sensor = event.sensor;             if (sensor.gettype() == sensor.type_accelerometer) {                  double value0 = event.values[0];                 double value1 = event.values[1];                 double value3 = event.values[2];                  long time = systemclock.uptimemillis() - mstarttime;                   try {                     if (f != null) {                         f.append(time+";"+value0+";"+value1+";"+value2 + "\r\n");                     }                 } catch (ioexception e) {                     log.e(tag, "cannot write file");                 }              }         }      };

this give csv text file, timestamp , 3 values.

ps. don't forget ask sd-card write permission.

also declare first:

    filewriter f; private sensormanager msensormanager; private sensoreventlistener msteplistener;

and don't forget close file..

try {     f.close(); } catch (ioexception e) {     log.e(tag, "cannot close file"); }
