How to detect system information like os or device type

Question

The most important things i want to know are the device type, the os version, if it has a hardware keyboard and maybe the screen resolution. but if you know other useful debug information please add them :)

i found this for the os version:

string+="OS Version: "+System.getProperty("os.version");

how do i get the other properties?

Answer 1

For screen resolution:

getWindow().getWindowManager().getDefaultDisplay().getWidth();
getWindow().getWindowManager().getDefaultDisplay().getHeight();

For hardware keyboard presence:

boolean keyboardPresent = (getResources().getConfiguration().keyboard != Configuration.KEYBOARD_NOKEYS);

Answer 2

Windowsize and keyboard presence were a good idea, i added some more infos for debug purpose:

String s="Debug-infos:";
s += "\n OS Version: " + System.getProperty("os.version") + "(" + android.os.Build.VERSION.INCREMENTAL + ")";
s += "\n OS API Level: " + android.os.Build.VERSION.SDK;
s += "\n Device: " + android.os.Build.DEVICE;
s += "\n Model (and Product): " + android.os.Build.MODEL + " ("+ android.os.Build.PRODUCT + ")";
