Detect my app’s own android:versionCode at run time

I put this in my subclassed android.app.Application but you can use it anywhere you have a context. Just change getPackageManager() to context.getPackageManager().

public int getVersion() {
    int v = 0;
    try {
        v = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;
    } catch (NameNotFoundException e) {
        // Huh? Really?
    }
    return v;
}
