 public void onStop() {
        information=Option.getText().toString();
        if (!information.equals("")) {
            //Toast.makeText(activity, "All unsubmitted information will be discarded", Toast.LENGTH_SHORT).show();
            LayoutInflater inflater = null;
            inflater = ( LayoutInflater )activity.
                    getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View v = inflater.inflate(R.layout.layout_back_press,null);
            AlertDialog.Builder builder = new AlertDialog.Builder(v.getContext());
            builder.setView(v);
            dialog = builder.create();
            dialog.show();
            TextView cancel = (TextView) v.findViewById(R.id.txt_Cancel);
            cancel.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    dialog.cancel();
                    //Toast.makeText(activity, "Feedback not sent", Toast.LENGTH_SHORT).show();

            });
            TextView send = (TextView) v.findViewById(R.id.txt_Send);
            send.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {

Answer 1

崩溃日志实际上告诉你问题：

android.util.SuperNotCalledException

主要生命周期功能必须始终调用其超级功能。所以只需添加

super.onStop();

作为方法的第一行，代码将起作用：）

PS：不要忘记删除else分支中的超级呼叫，因为不再需要了。

Answer 2

你应该在onStop上调用super。

@Override
public void onStop() {
    super.onStop();
    // Your code here
}

Answer 3

在提出问题之前请做一些研究，这个问题已在这里得到答案： android.app.SuperNotCalledException: Activity did not call through to super.onStop()

onStop中的编码崩溃了应用
