You are getting the error :
cannot be cast to android.app.Activity
because you are trying to load uploadPost as an Activity but it extends Fragment so you get the "cannot be cast to android.app.Activity" error.
You must decide whether you want to load it as a Fragment or an Activity. If you want to load uploadPost as an Activity you need to extend to an Activity not Fragment
EDIT
If you wish to continue to use it as a Fragment you must use a FragmentTransaction to either add() the Fragment or replace() a Fragment in your activity layout.
You can replace a Fragment like this example:
Fragment fragment = new UploadPost();
if(fragment != null) {
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
//If you want to play around with different transaction animations
//fragmentTransaction.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out);
fragmentTransaction.replace(R.id.content_main, fragment, "0");
fragmentTransaction.commit();
}
Where R.id.content_main is just a RelativeLayout in my MainActivity which is replaced by the uploadPost fragment.
And as 0X0nosugar indicated: It is java naming convention to capitalize class names. Please adopt this convention--otherwise you will make it more difficult to understand your code.
EDIT 2
Often a Fragment will be used to swap views in an container Activity. For example I use them to swap views in combination with a DrawerLayout. In this case I will continue to replace fragments, but never really remove one explicitly.
For example I will have a xml layout file very similar to your "SearchActivity" file. Just below the </android.support.design.widget.AppBarLayout> tag I will introduce a RelativeLayout with the id android:id="#+id/content_main". This RelativeLayout is just a dummy container view and is being replaced with whatever is in my selected Fragment. So you would need to change the onClick code to replace the fragment as I showed above.
With another action you might want to either remove that fragment or replace it with another... that all depends on your app design--which I do not know.

The app does not crash on runtime, it only displays the map without the RecyclerView. In my gradle file i inlcuded the dependencies i needed. I tried messing around with the gradle file, nothing seems to work. In my logcat I have the following java.io.FileNotFoundException-No such file or directory.

Problem in library de.hdodenhof.circleimageview.CircleImageView. check this
https://github.com/hdodenhof/CircleImageView/issues/121
If you need to circle imageview you can use glide transformation with imageview
https://bumptech.github.io/glide/doc/transformations.html
Example glide v4:
RequestOptions options = new RequestOptions();
options.CircleCrop();
Glide.with(fragment)
.load(url)
.apply(options)
.into(imageView);

SwipeRefreshLayout got error and cannot refresh (load more) in the first time

I am trying to implement "Swipe to load more" method in my application but I got that error when I swipe down in the first time. This is what it showed in the console:

UPDATE ISSUE's REASON
I found the reason of that issue. It due to I force the listview scroll to the bottom when it init with this code :
android:stackFromBottom="true"
I replace that code with this but still have same issue:
lv_message.post(new Runnable() {
#Override
public void run() {
lv_message.setSelection(lv_message.getCount() -1);
}
});

I think the problem is , You are trying to show , dismiss and refresh swipeRefreshLayout inside the same method i.e onRefresh().
Make seperate methods for showing and dismissing dialog and invoke them from the place where they are required as I have done below:
#Override
public void onRefresh() {
// refresh code here.
}
#Override
public void showDialog() {
swipeRef.post(new Runnable() {
#Override
public void run() {
if(swipeRef != null)
swipeRef.setRefreshing(true);
}
});
}
#Override
public void dismissDialog() {
if(swipeRef!=null && swipeRef.isShown() )
swipeRef.setRefreshing(false);
}

Error saving image from camera(cwac camera)

I tried the demo of the library and is working fine on the same mobile set. Also there seems to be no problem while I was testing it on Nexus 5. I am trying this library for the first time and have no clue for solving this

in app purchase saving buttons states

I am trying to develop an app with in app purchases in it, simply what I want to do is to have two buttons one to make the purchase(enabled) the second button to open the activity after purchase (at first is disabled then after purchase is enabled).
Two problems the first was to save the buttons state after the purchase as they were getting reset every time I restart the app. So I did some researches and found about shared preference and I did implemented it but the second problem came out that buttons statuses doesn’t seem to work right (between disabled to enabled) after implementing shared preference.
Note that in the app I have two buttons that do the same thing one enables the other buttons but with no purchase made and they work fine with shared preference, but the buttons associated with the in app purchase stopped changing their status from disabled to enabled after the purchase is made (they stay disabled after the purchase)
Here is my xml code:

Thanks a lot.

Try to call methods from Java part , don't call from xml using android:onClick
Use default value of the button(buy) state to false in shared preference .
and in this screen implement this if check inside oncreate() method as:
if(button(buy) state ==false)
{
//make button(buy) state enable
//make activity button state disable
}
else
{
//make button(buy) state disable
//make activity button state enable
}
And make button(buy) and activity calling button state to true/false according to result after in app purchase and also update shared prefrence state according to result
