Make implementation of isEmpty consistent with implementation of getCount in HeaderListViewAdapter

Fix for Issue ID 18316. Make isEmpty() return false when getCount() returns a non-zero value. So that the list cannot be considered empty when a header or footer is present.

Check ProcessesReady before broadcast

Most of the time testIsSystemReady is used to know if we are allowed to broadcast intents.
But in broadcast intent method we check mProcessesReady flag (not mSystemReady).
If we broadcast after systemReady flag but before ProcessesReady flag, system will crash

Adding condition to check if system & processes are ready fix that race condition

Fragment animations are not being saved across configuration changes

As per comment #5 in issue #25994:

The problem here is not that the state isn't saved and restored, the problem is how the BackStackRecord is rebuilt.  The ops themselves do save and restore the state, the problem is in BackStackRecord#addOp.

    void addOp(Op op) {
        if (mHead == null) {
            mHead = mTail = op;
        } else {
            op.prev = mTail;
            mTail.next = op;
            mTail = op;
        }
        op.enterAnim = mEnterAnim;
        op.exitAnim = mExitAnim;
        op.popEnterAnim = mPopEnterAnim;
        op.popExitAnim = mPopExitAnim;
        mNumOp++;
    }

The enter, exit, popEnter and popExit animations are overwritten with whatever is currently in the record, which during the restoration process these are 0 so the values which were saved in the ops is lost.

Session: Add a shortcut in detecting if a window that contains the wallpaper is null or not

originally, a null window would be detected in WindowManagerService, an exception would be thrown, and then that would be caught in Session

NotificationManagerService: notifications with icon==0 are FINE WITH US

This warning reminds me of that saying about squeaky wheels... "the squeaky wheel gets PUNCHED IN THE HEAD"
