Else without if - android studio/java

I'm writing a code for a calculator and I'm having this one error which I just can't find, it's an "else without if" error at the last "else" in the code...If you could help me figure out what it is I would be grateful :)

ArrayList<String> arrayList = new ArrayList<String>();
String string = "";
String string1 = "";

public void onClick1(View v) {

    TextView textView2 = (TextView) findViewById(R.id.textView2);

    Button button = (Button) v;

    string = (String) button.getText().toString();

    if (!string.contains("+") && !string.contains("-") && !string.contains("*") && !string.contains("/")) {

        string1 = string1 + string;

        if (arrayList.size() > 0) {

            arrayList.remove((arrayList.size() - 1));


        }

        arrayList.add(string1);
    } else {
        arrayList.add(string);
        arrayList.add(string);
        string1 = "";

    }

    //textView2.setText(textView2.getText().toString()+string);

    textView2.setText(arrayList.toString());
}


public void onClick(View v) {

    TextView textView1 = (TextView) findViewById(R.id.textView);

    int calc = 0;
    int c = arrayList.size();


    while (c != 1) {

        if (c > 3) {

            if (arrayList.get(3).contains("*") || arrayList.get(3).contains("/")) {

                if (arrayList.get(3).contains("*")) {
                    calc = Integer.parseInt(arrayList.get(2)) * Integer.parseInt(arrayList.get(4));
                }
                if (arrayList.get(3).contains("/")) {
                    calc = Integer.parseInt(arrayList.get(2)) / Integer.parseInt(arrayList.get(4));
                }
