Hello.I make an apk for listen bluetooth and i want to get value data from
function ListenBt() to pass to another function upload().I make public
final string data but no work!Any help?
public class Activity2 extends Activity {
public String strValue;
public String strValue2;
public int t;//Temperature
public String urlt;
public final String data="0";
TextView txt;
Handler handler = new Handler();
TextView myLabel;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity2);
//txt=(TextView)findViewById(R.id.txt);
myLabel = (TextView)findViewById(R.id.label);
}
private class DownloadWebPageTask extends AsyncTask<String, Void,
String> {
@Override
protected String doInBackground(String... urls) {
String response = "";
for (String url : urls) {
DefaultHttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse execute = client.execute(httpGet);
InputStream content = execute.getEntity().getContent();
BufferedReader buffer = new BufferedReader(new
InputStreamReader(content));
String s = "";
while ((s = buffer.readLine()) != null) {
response += s;
}
} catch (Exception e) {
e.printStackTrace();
}
}
return response;
}
@Override
protected void onPostExecute(String result) {
TextView text3 = (TextView) findViewById(R.id.txt3);
text3.setText(result);
try {
sendData(result);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public void readWebpage(View view) {
DownloadWebPageTask task = new DownloadWebPageTask();
task.execute(new String[] { strValue });
}
protected void onStart() {
super.onStart();
try
{
findBT();
openBT();
}
catch (IOException ex) { }
runnable.run();
}
private Runnable runnable = new Runnable()
{
public void run()
{
DownloadWebPageTask task = new DownloadWebPageTask();
task.execute(new String[] { strValue });
beginListenForData();
upload();
if(work){ handler.postDelayed(this, 30000);}//Refresh page time
}
};
void ListenBt()
{
final Handler handler = new Handler();
final byte delimiter = 10; //This is the ASCII code for a newline
character
stopWorker = false;
readBufferPosition = 0;
readBuffer = new byte[1024];
workerThread = new Thread(new Runnable()
{
public void run()
{
while(!Thread.currentThread().isInterrupted() && !stopWorker)
{
try
{
int bytesAvailable =
mmInputStream.available();
if(bytesAvailable > 0)
{
byte[] packetBytes = new byte[bytesAvailable];
mmInputStream.read(packetBytes);
for(int i=0;i<bytesAvailable;i++)
{
byte b = packetBytes[i];
if(b == delimiter)
{
byte[] encodedBytes = new
byte[readBufferPosition];
System.arraycopy(readBuffer, 0,
encodedBytes, 0, encodedBytes.length);
final String data = new
String(encodedBytes, "US-ASCII");
readBufferPosition = 0;
handler.post(new Runnable()
{
public void run()
{
myLabel.setText(data);
}
});
}
else
{
readBuffer[readBufferPosition++] = b;
}
}
}
}
catch (IOException ex)
{
stopWorker = true;
}
}
}
});
workerThread.start();
}
public void upload(){
t = Integer.parseInt(data);
SimpleHttpPut.main(urlt,t);//Upload data class
}
