android后台上传数据demo
1、界面启动后开启服务
public class UploadlogActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = new Intent(this,UploadService.class);
startService(intent);
}
2、后台服务组件负责上传数据
public class UploadService extends Service {
private Timer timer;
private TimerTask task;
private KeyguardManager km;
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
km = (KeyguardManager) getSystemService(KEYGUARD_SERVICE);
// 定期的上传用户的数据.
timer = new Timer();
final Random random = new Random();
task = new TimerTask() {
@Override
public void run() {
if (km.inKeyguardRestrictedInputMode()) {//锁屏状态下
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.addCategory(Intent.CATEGORY_BROWSABLE);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri
.parse("http://192.168.1.2:8080/web/aaa?info="
+ random.nextInt()));
startActivity(intent);
}
}
};
timer.schedule(task, 1000, 2000);
super.onCreate();
}
}
