I assume (It would be better if you post the crash log along with your question, so that we can help you better and stop assuming) you are getting a null pointer exception on the following code: i.putExtra(“temper”, temp.getText().toString()); In your code you declared temp, but it is never initialised. You need to initialise temp … Read more

It crashes because you are accessing argv[1] which would hold a command line argument (other than the program’s name) if there was one. You should check whether argc is greater than 1. Why greater than 1? Because the first command line argument is the name of the program itself. So argc is always greater than … Read more
Replace R.id.tvFeed with Framelayout’s id or default id android.R.id.content. if (savedInstanceState == null) { getFragmentManager().beginTransaction() .add(android.R.id.content, new PlaceholderFragment()) .commit(); } and remove the code from the onOptionsItemSelected() method. if (id == R.id.tvFeed) { return true; } solved Android app crashes by switching the activity

Not likely to be your crash, but this code is terrible: if (fnameFile.is_open()) { while (fnameFile.eof() == false) { plFname.resize(numFnames); getline(fnameFile,line); numFnames += 1; } fnameFile.close(); } It doesn’t check for end of file correctly, because end of file happens during getline, not before. And the line variable goes nowhere. Try while (getline(fnameFile,line)) plFnames.push_back(line); fnameFile.close(); … Read more

This scanf(“%s”,kar[1000]); should trigger a compiler warning, as you pass a char where a char* is expected. You pass the 1001st element of kar (which is out of kar‘s bounds, BTW). In C array indices start with 0 for the 1st element. To scan into kar, just pass the address of kar‘s 1st element. scanf(“%s”, … Read more
The main problem I see with your code is the reading loop, it has mainly two issues Read: Why is while (!feof(rPtr)) always wrong. You must check the return value of scanf(), and prevent scanf()‘s from overflowing the destination buffer, so the loop condition should be while (fscanf(rPtr, “%14s%lf%lf%lf”, fromDb.name, &fromDb.dArea, &fromDb.dLength, &fromDb.dFormFactor) == 4) … Read more
