I couldn't get that one to work so I'm trying something else. Here's where the button is pressed:
btnMP.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { memNum = memNum + Double.parseDouble(txtCalc.getText().toString()); operator = 0; } }); Here's a thingie I hammered together from parts: // Save MEMORY public void WriteMemory(OnClickListener onClickListener, double memNum){ File sdcard = Environment.getExternalStorageDirectory(); File destinationdir = new File(sdcard,"/download/calculator"); destinationdir.mkdir(); File destinationfile = new File(destinationdir,"memory.dat"); FileOutputStream fOut = null; OutputStreamWriter osw = null; try{ destinationfile.createNewFile(); fOut = new FileOutputStream(destinationfile); osw = new OutputStreamWriter(fOut); osw.write((int) memNum); osw.flush(); Toast.makeText((Context) onClickListener, "Memory saved",Toast.LENGTH_SHORT).show(); } catch (Exception e) { e.printStackTrace(); // Toast.makeText((Context) onClickListener, "Memory not saved",Toast.LENGTH_SHORT).show(); } finally { try { osw.close(); fOut.close(); } catch (IOException e) { e.printStackTrace(); } } } This is called by inserting WriteMemory(this,memNum); in the button routine thusly: btnMP.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { memNum = memNum + Double.parseDouble(txtCalc.getText().toString()); operator = 0; } WriteMemory(this,memNum); }); The file is created but nothing is written in it. What's missing? Brian On Sep 28, 3:38 pm, "Yusuf Saib (T-Mobile USA)" <yusuf.s...@t- Mobile.com> wrote: > txt is declared inside your "if (hasChanged) {" scope.
