Android studio获取GNSS原始数据

在Android Studio中获取GNSS原始数据，你可以使用Android的GNSS API。这个API在Android Nougat（7.0）及以上版本的操作系统中可用。你可以使用以下步骤来获取GNSS原始数据：

1. 在build.gradle文件的dependencies中添加以下依赖项：implementation 'com.google.android.gms:play-services-location:17.0.0'

2. 在你的代码中，创建一个GoogleApiClient对象，并在onConnected回调方法中请求GNSS原始数据权限：

    import com.google.android.gms.common.api.GoogleApiClient;
    import com.google.android.gms.location.LocationServices;
    
    public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks {
    
        private GoogleApiClient mGoogleApiClient;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .addConnectionCallbacks(this)
                    .addApi(LocationServices.API)
                    .build();
    
            // 连接到GoogleApiClient
            mGoogleApiClient.connect();
        }
    
        @Override
        public void onConnected(@Nullable Bundle bundle) {
            // 请求GNSS原始数据权限
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
                LocationServices.getFusedLocationProviderClient(this).requestLocationUpdates(mLocationRequest, mLocationCallback, Looper.myLooper());
                LocationServices.getFusedLocationProviderClient(this).registerGnssMeasurementsCallback(mGnssMeasurementsCallback);
            }
        }
    
        //其他代码...
    }

3. 实现GnssMeasurementsEvent.Callback接口，并重写onGnssMeasurementsReceived方法来处理接收到的GNSS原始数据：

    import android.location.GnssMeasurementsEvent;
    
    public class GnssMeasurementsCallback extends GnssMeasurementsEvent.Callback {
    
        @Override
        public void onGnssMeasurementsReceived(GnssMeasurementsEvent eventArgs) {
            // 处理接收到的GNSS原始数据
        }
    
        //其他代码...
    }

4. 在onConnected方法中注册GnssMeasurementsCallback回调：

    import com.google.android.gms.location.LocationServices;
    
    public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks {
    
        private GoogleApiClient mGoogleApiClient;
        private GnssMeasurementsCallback mGnssMeasurementsCallback;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            // 创建mGnssMeasurementsCallback对象
            mGnssMeasurementsCallback = new GnssMeasurementsCallback();
    
            // 其他代码...
        }
    
        @Override
        public void onConnected(@Nullable Bundle bundle) {
            // 请求GNSS原始数据权限
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
                LocationServices.getFusedLocationProviderClient(this).requestLocationUpdates(mLocationRequest, mLocationCallback, Looper.myLooper());
                LocationServices.getFusedLocationProviderClient(this).registerGnssMeasurementsCallback(mGnssMeasurementsCallback);
            }
        }
    
        //其他代码...
    }

通过这些步骤，你就可以在Android Studio中获取到GNSS原始数据了。请注意，在使用GNSS原始数据之前，你需要在AndroidManifest.xml文件中添加相应的权限，例如ACCESS_FINE_LOCATION。
