I try this but work only for text no out the data....Any help?
public void blinkLED(View v){
//Find the directory for the SD Card using the API
//*Don't* hardcode "/sdcard"
String line = null;
File sdcard = Environment.getExternalStorageDirectory();
//Get the text file
File file = new File(sdcard,"LEDstate.txt");
//Read text from file
StringBuilder text = new StringBuilder();
try {
BufferedReader br = new BufferedReader(new FileReader(file));
//String line;
while ((line = br.readLine()) != null) {
// mOutputStream.write(line.getBytes());
text.append(line);
text.append('\n');
}
}
catch (IOException e) {
//You'll need to add proper error handling here
}
//Find the view by its id
TextView tv = (TextView)findViewById(R.id.textView2);
//Set the text
tv.setText(text);
if (mOutputStream != null) {
try {
mOutputStream.write(text.getBytes());
} catch (IOException e) {
// TODO Auto-generated catch block
Log.e(TAG, "write failed", e);
}
}
I think the wrong is when convert text to byte...my file is 1 byte 0 or
1....
