E/ProcessKiller( 229): Sending SIGKILL to process 1405

[arthled]

when the network instability，my mqtt connection while lost and the application will be kill probably.logs like below:

E/ProcessKiller( 229): Process com.example.myapplication (1405) has open file /storage/sdcard0/Android/data/com.example.myapplication/files/MqttConnection/MT8735303801b7da580ac585-tcplecbrokermapatcloudcom1883/.lck (deleted)
E/ProcessKiller( 229): Sending SIGKILL to process 1405

I try to open and close network to simulate the scene,but never success. it happens with probability.my code like below:

/**

• connect option
  **/
  public void connect() {
  try {
  if(isConnecting){
  return;
  }
  if(client != null){
  if (!client.isConnected()) {
  client.connect(options,null,connectListener);
  }
  return;
  }
  isConnecting = true;
  client = new MqttAndroidClient(mContext, SERVER_HOST, DeviceData.deviceNo);
  options = new MqttConnectOptions();
  options.setCleanSession(true);
  options.setUserName(username);
  options.setPassword(userpsw.toCharArray());
  options.setConnectionTimeout(100);
  options.setKeepAliveInterval(20);
  options.setAutomaticReconnect(true);
  options.setWill(Mqttcmd.cmd_head + DeviceData.deviceNo + Mqttcmd.device2server_report, getLoginMessage().getPayload(), 0, true);
  client.setCallback(new PushCallback());
  client.connect(options, null, connectListener);
  } catch (MqttException e) {
  e.printStackTrace();
  isConnecting = false;
  if(callBack != null)callBack.onConnectException(e);
  if(isNeedConnect && connect_try_times > 0 && isNetworkAvailable()) {
  StaticData.handler.removeCallbacks(runnable);
  StaticData.handler.postDelayed(runnable,60*1000);
  }
  }
  }

/**

  **/
  private IMqttActionListener connectListener = new IMqttActionListener() {
  @OverRide
  public void onSuccess(IMqttToken asyncActionToken) {
  }

  @OverRide
  public void onFailure(IMqttToken asyncActionToken, Throwable exception) {
  exception.printStackTrace();
  isConnecting = false;
  if(callBack != null) callBack.onConnectFail(exception);
  if(isNeedConnect && connect_try_times > 0 && isNetworkAvailable()) {
  StaticData.handler.removeCallbacks(runnable);
  StaticData.handler.postDelayed(runnable,60*1000);
  }
  }
  };
  /**

  public class PushCallback implements MqttCallback {
  public void connectionLost(Throwable cause) {
  if(callBack != null) callBack.onConnectLost(cause);
  if(isNeedConnect && connect_try_times > 0 && isNetworkAvailable()) {
  StaticData.handler.removeCallbacks(runnable);
  StaticData.handler.post(runnable);
  }
  }
  @OverRide

  }

  }

};
