I’m new to XPOSED and currently researching it for my project. I’m using Java and XPOSED to hook into the SystemClock.uptimeMillis() function and increase the result by one day. However, when I launch the target application, the UI components are not displayed, and I only see a blank white screen.

Here are some details:

1. I’m using XPOSED to modify SystemClock.uptimeMillis().
2. The modification adds 24 hours (1 day) to the original return value.
3. The target application is a simple app I created for research purposes.
4. The target application is developed by me specifically for this research, and there are no XPOSED detection techniques implemented in it.

My hook implementation looks something like this:

XposedHelpers.findAndHookMethod(SystemClock.class, "uptimeMillis", new XC_MethodHook() {
    @Override
    protected void afterHookedMethod(MethodHookParam param) throws Throwable {
        long originalTime = (long) param.getResult();
        long modifiedTime = originalTime + (24 * 60 * 60 * 1000); // Add 1 day in milliseconds
        param.setResult(modifiedTime);
    }
});
