Buggy source:

  }
  long availMem=readAvailMem() - SECONDARY_SERVER_MEM;
  if (availMem < 0) {

Fixed version (ground truth):
void refreshUi(boolean dataChanged){
  if (dataChanged) {
    ServiceListAdapter adapter=(ServiceListAdapter)(getListView().getAdapter());
    adapter.refreshItems();
    adapter.notifyDataSetChanged();
  }
  long availMem=readAvailMem() - SECONDARY_SERVER_MEM;
  if (availMem < 0) {
    availMem=0;
  }
synchronized (mState.mLock) {
    if (mLastNumBackgroundProcesses != mState.mNumBackgroundProcesses || mLastBackgroundProcessMemory != mState.mBackgroundProcessMemory || mLastAvailMemory != availMem) {
      mLastNumBackgroundProcesses=mState.mNumBackgroundProcesses;
      mLastBackgroundProcessMemory=mState.mBackgroundProcessMemory;
      mLastAvailMemory=availMem;
      String availStr=availMem != 0 ? Formatter.formatShortFileSize(this,availMem) : "String_Node_Str";
      String sizeStr=Formatter.formatShortFileSize(this,mLastBackgroundProcessMemory);
      mBackgroundProcessText.setText(getResources().getString(R.string.service_background_processes,mLastNumBackgroundProcesses,availStr,sizeStr));
    }
    if (mLastNumForegroundProcesses != mState.mNumForegroundProcesses || mLastForegroundProcessMemory != mState.mForegroundProcessMemory) {
      mLastNumForegroundProcesses=mState.mNumForegroundProcesses;
      mLastForegroundProcessMemory=mState.mForegroundProcessMemory;
      String sizeStr=Formatter.formatShortFileSize(this,mLastForegroundProcessMemory);
      mForegroundProcessText.setText(getResources().getString(R.string.service_foreground_processes,mLastNumForegroundProcesses,sizeStr));
    }
    mLastNumServiceProcesses=mState.mNumServiceProcesses;
    mLastServiceProcessMemory=mState.mServiceProcessMemory;
    float totalMem=availMem + mLastBackgroundProcessMemory + mLastForegroundProcessMemory+ mLastServiceProcessMemory;
