public class Connectionservice extends service { ..... public void restartConnection() { try { Log.i(this.toString(),"AttempTing to reconnect..."); // increase the wait between each retry until the max is reached int sleepTime = reconnectCounter * MIN_RECON_WAIT; if (sleepTime > MAX_RECON_WAIT) { sleepTime = MAX_RECON_WAIT; } String msg = "The connection has been lost. Restart attempt will start in: " + sleepTime/1000 + " seconds"; Log.i(this.toString(),msg); Toast.makeText(getApplicationContext(),msg,Toast.LENGTH_LONG).show(); Thread.sleep(sleepTimE); // increment the counter reconnectCounter++; this.startConnectionThread(); } catch (Exception E) { Log.e(this.toString(),"Exception: " + e.toString()); e.printStackTrace(); } }// end retartConnection
这是我头上的一些代码.我现在没有SDK来测试它,但我认为它应该给你一个一般的想法.
public class Connectionservice extends service { private Handler handler = new Handler(); public void restartConnection(){ int sleepTime = reconnectCounter * MIN_RECON_WAIT; if (sleepTime > MAX_RECON_WAIT) { sleepTime = MAX_RECON_WAIT; } String msg = "The connection has been lost. Restart attempt will start in: " + sleepTime/1000 + " seconds"; (new Timer()).schedule( new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { Toast.makeText(getApplicationContext(),"msg",Toast.LENGTH_LONG).show(); reconnectCounter++; this.startConnectionThread() } }); } },sleepTimE); }//end restartConnection }//end Connectionservice
