私は、データベースに保存するWebサービスによってこれらの値を消費するために、Androidフォンからセンサー値を取得するAndroidアプリケーションに取り組んでいます。センサー値をテストするための実際のデバイスがないため、センサーシミュレーター[http://code.google.com/p/openintents/wiki/SensorSimulator] [1]を使用しました。問題は、実行するたびにアクティビティエラーが発生します。アクティビティのコードは次のとおりです（API 15 Google APIプラットフォームを使用しています：4.0.3）
import org.openintents.sensorsimulator.hardware.Sensor;
import org.openintents.sensorsimulator.hardware.SensorEvent;
import org.openintents.sensorsimulator.hardware.SensorEventListener;
import org.openintents.sensorsimulator.hardware.SensorManagerSimulator;
public class SimulationActivity extends Activity implements SensorEventListener {
private SensorManagerSimulator mSensorManager;
private Sensor mTemperature;
private TextView mTemperatureLabel;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mTemperatureLabel = (TextView) findViewById(R.id.temperature);
mSensorManager = SensorManagerSimulator.getSystemService(this,SENSOR_SERVICE);
mSensorManager.connectSimulator();
}
@Override
protected void onResume() {
super.onResume();
mSensorManager.registerListener(this,
mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
SensorManager.SENSOR_DELAY_FASTEST);
mSensorManager.registerListener(this,
mSensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD),
SensorManager.SENSOR_DELAY_FASTEST);
mSensorManager.registerListener(this,
mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION),
SensorManager.SENSOR_DELAY_FASTEST);
mSensorManager.registerListener(this,
mSensorManager.getDefaultSensor(Sensor.TYPE_TEMPERATURE),
SensorManager.SENSOR_DELAY_FASTEST);
}
@Override
protected void onStop() {
mSensorManager.unregisterListener(this);
super.onStop();
}
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
public void onSensorChanged(SensorEvent event) {
switch (event.type) {
case Sensor.TYPE_ORIENTATION: {
Log.i("Sensor changed ", " Orientation ");
mTemperatureLabel.setText("orientation");
}
break;
case Sensor.TYPE_LIGHT: {
Log.i("Sensor changed ", " light ");
mTemperatureLabel.setText("light");
}
break;
case Sensor.TYPE_TEMPERATURE: {
Log.i("Sensor changed ", " temperature ");
mTemperatureLabel.setText("temperature");
}
break;
case Sensor.TYPE_PRESSURE: {
Log.i("Sensor changed ", " pressure ");
mTemperatureLabel.setText("pressure ");
}
break;
}
}
}
これがエラーメッセージです
