Data collection time is too long #19

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
It looks like the time of data collection during the creation of a report is 
quite long and make the UI freeze for a moment. Might be longer on 1.X android 
version.

Interesting point: a simple "new Date().toString()" takes 3927ms on Android 1.5 
emulator and 20ms on Android 2.2 emulators.

Replacing it with android.text.format.Time reduces to 80ms on 1.5 emu but 
increases it to 80ms on 2.2...

Saving the report to a file was also an issue:
  * on android versions prior to 2.0, storing with Properties.store() was taking nearly 4 seconds because of the always present comment header which is calling new Date().toString(). Switching to Properties.storeToXML() reduces this time to 0.5s
  * on android versions from 2.0 and later, Properties.storeToXML() takes 1.5s for a reason still unknown to me.... and Properties.store() takes only 0.2s.

So, I implemented storeToXML() for API levels < 5 and kept store() for others...
