Re: [android-developers] Reading ROM version through code

Hey guys... 

This code works... although I'm not that keen on it, since it is definitely not part of the jars available. But it works:

    @Override

    public void onCreate(Bundle savedInstanceState)

    {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        TextView arch = (TextView)findViewById(R.id.arch);

        TextView name = (TextView)findViewById(R.id.name);

        TextView version = (TextView)findViewById(R.id.version);

        TextView roversion = (TextView)findViewById(R.id.roversion);

        TextView rofingerprint = (TextView)findViewById(R.id.rofingerprint);

        arch.setText("os.arch: " + System.getProperty("os.arch"));

        name.setText("os.name: " + System.getProperty("os.name"));

        version.setText("os.version: " + System.getProperty("os.version"));

        roversion.setText("ro.product.version: " + getProp("ro.product.version", "Not found"));

        rofingerprint.setText("ro.build.fingerprint: " + getProp("ro.build.fingerprint", "Not found"));

    }

    private String getProp(String prop, String defaultVal)

    {

        String line = defaultVal;

        try {

            Process ifc = Runtime.getRuntime().exec("getprop " + prop);

            BufferedReader bis = new BufferedReader(new InputStreamReader(ifc.getInputStream()));

            line = bis.readLine();

            ifc.destroy();

        } catch (java.io.IOException e) {

        }

        return line;

    }

This returns:

TextView arch = (TextView)findViewById(R.id.arch);

TextView name = (TextView)findViewById(R.id.name);

TextView version = (TextView)findViewById(R.id.version);

TextView roversion = (TextView)findViewById(R.id.roversion);

TextView rofingerprint = (TextView)findViewById(R.id.rofingerprint);

arch.setText("os.arch: " + System.getProperty("os.arch"));

name.setText("os.name: " + System.getProperty("os.name"));

version.setText("os.version: " + System.getProperty("os.version"));

roversion.setText("ro.product.version: " + System.getProperty("ro.product.version"));

rofingerprint.setText("ro.build.fingerprint: " + System.getProperty("ro.build.fingerprint"));

Which gave me this output on my HTC Legend:

os.arch : armv6l

os.name: Linux

os.version: 2.6.32.17-g30929af

ro.product.version: 3.15.405.3

ro.build.fingerprint: htc_wwe/htc_legend/legend/legend:2.2/FRF91/291292:user/release-keys

ro.product.version: null

So this didn't work either unfortunately... I'll keep looking!

Open an adb shell, type "getprop" and look at the result.

Some entries which may be of interest:

ro.build.fingerprint

ro.build.version.*

ro.product.version

 

These should be readable by apps; what I don't know off the top of my head is which (if any) are "stable API's" and which are private and thus subject to change without notice.
