Constructors Summary
Methods Summary
public static booleanensureVersion(android.app.Activity activity, int minVersion)
Check that the library's version is at least the given minimum version, displaying a dialog to have the user install an update if that is not true. The dialog is displayed as a DialogFragment in your activity if a newer version is needed. If a newer version is needed, false is returned.

        final FragmentManager fm = activity.getFragmentManager();
        final String dialogTag = LIBRARY_PACKAGE + ":version";
        Fragment curDialog = fm.findFragmentByTag(dialogTag);

        if (getVersion(activity) >= minVersion) {
            // Library version is sufficient.  Make sure any version dialog
            // we had shown is removed before returning.
            if (curDialog != null) {
                fm.beginTransaction().remove(curDialog).commitAllowingStateLoss();
            }
            return true;
        }

        // The current version of the library does not meet the required version.
        // If we don't already have a version dialog displayed, display it now.
        if (curDialog == null) {
            curDialog = new VersionDialog();
            fm.beginTransaction().add(curDialog, dialogTag).commitAllowingStateLoss();
        }

        // Tell the caller that the current version is not sufficient.
        return false;
public static intgetVersion(android.content.Context context)
Return the version number of the currently installed library.
