What is good practice to send date through bluetooth Arduino and show it
in Andorid

I am sending two sensors data read on Arduino and send it through
bluetooth to Android. What is a good sending practice? Because i have a
problem to show those two values in Android in different TextViews. I
added 10000 to first value to make a difference and to easier divide them
in Android. But Android app is crashing after receiving a data.
On Arduino side:
meetAndroid.send(tempS);
meetAndroid.send(temp2S);
delay(100);
