[Antonis Kanaris]

 
 

I have created the start alarm as shown below

 public class MyScheduleReceiver extends BroadcastReceiver {

   // Restart service every 30 secondsprivate static final long REPEAT_TIME = 
1000 * 5;
@Overridepublic void onReceive(Context context, Intent intent) {
  AlarmManager service = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
 Intent i = new Intent(context, MyStartServiceReceiver.class);
 PendingIntent pending = PendingIntent.getBroadcast(context, 0, i,
PendingIntent.FLAG_CANCEL_CURRENT);Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 5);
service.setInexactRepeating(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), REPEAT_TIME, pending);

I crate this for stop alarm and i call it from main activity.Manifest i 
think is ok...Work repeat but no stop!!!

  public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.setup);

sendBroadcast(new Intent(this,MyScheduleReceiver.class));
}
public void StopRepeat(View view) {

sendBroadcast(new Intent(this,MyStopReceiver.class));   
}

 public class MyStartServiceReceiver extends BroadcastReceiver {


 public void onReceive(Context context, Intent intent) {

  Toast.makeText(context, "Repeat service!.",
   Toast.LENGTH_LONG).show();
}

  public class MyStopReceiver extends BroadcastReceiver {

  // Restart service every 30 seconds
  private static final long REPEAT_TIME = 1000 * 5;

  @Override
  public void onReceive(Context context, Intent intent) {
AlarmManager service = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
Intent istop = new Intent(context, MyStartServiceReceiver.class);
PendingIntent pending = PendingIntent.getBroadcast(context, 0, istop,
PendingIntent.FLAG_CANCEL_CURRENT);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 5);

  service.cancel(pending);

But the service is not stopping. What might be the issue?Thanks.

[android-developers] Problem read data from file out to usb

[Antonis Kanaris]

 I try this but work only for text no out the dataAny 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
