在Android中用e.printStackTrace()

Is it a bad idea to use printStackTrace() in Android Exceptions like this?

} catch (Exception e) {
    e.printStackTrace();
}
} catch (Exception e) {
    e.printStackTrace();
}

java  android  exception  printstacktrace

Yes, it is a bad idea. You should instead use Android's built-in log class specifically designed for these purposes: http://developer.android.com/reference/android/util/Log.html

It gives you options to log debug messages, warnings, errors etc.

I believe this is what you need:

catch (Exception e) {
     Log.e(TAG,Log.getStackTraceString(e)); 
}
catch (Exception e) {
     Log.e(TAG,Log.getStackTraceString(e)); 
}
