Voglio che il codice venga eseguito continuamente in background. Non voglio farlo in un servizio. C'è un altro modo possibile?
Ho provato a chiamare la Thread
classe nel mio Activity
ma i miei Activity
resti in background per qualche tempo e poi si ferma. La Thread
classe smette anche di funzionare.
class testThread implements Runnable {
@Override
public void run() {
File file = new File( Environment.getExternalStorageDirectory(), "/BPCLTracker/gpsdata.txt" );
int i = 0;
RandomAccessFile in = null;
try {
in = new RandomAccessFile( file, "rw" );
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//String line =null;
while ( true ) {
HttpEntity entity = null;
try {
if ( isInternetOn() ) {
while ( ( line = in.readLine() ) != null ) {
HttpClient client = new DefaultHttpClient();
String url = "some url";
HttpPost request = new HttpPost( url );
StringEntity se = new StringEntity( line );
se.setContentEncoding( "UTF-8" );
se.setContentEncoding( new BasicHeader( HTTP.CONTENT_TYPE, "application/json" ) );
entity = se;
request.setEntity( entity );
HttpResponse response = client.execute( request );
entity = response.getEntity();
i++;
}
if ( ( line = in.readLine() ) == null && entity != null ) {
file.delete();
testThread t = new testThread();
Thread t1 = new Thread( t );
t1.start();
}
} else {
Thread.sleep( 60000 );
} // end of else
} catch (NullPointerException e1) {
e1.printStackTrace();
} catch (InterruptedException e2) {
e2.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}// end of while
}// end of run
}
