Android:GoogleAppClient尚未连接?
更新用户的当前位置 我在我的项目中实施以下方法: GoogleAppClient.ConnectionCallbacks, GoogleAppClient.OnConnectionFailedListener 执行项目时,将发生以下错误:Android:GoogleAppClient尚未连接?,android,location,google-api-client,Android,Location,Google Api Client,更新用户的当前位置 我在我的项目中实施以下方法: GoogleAppClient.ConnectionCallbacks, GoogleAppClient.OnConnectionFailedListener 执行项目时,将发生以下错误: java.lang.IllegalStateException: GoogleApiClient is not connected yet. 代码中有一个错误: LocationServices.FusedLocationApi.requestLocatio
java.lang.IllegalStateException: GoogleApiClient is not connected yet.
代码中有一个错误:
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
已经提出了许多解决方案,如和
但不能解决任何问题
请帮忙解决它
onCreate方法中的我的代码:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
FirebaseCrash.report(new Exception("Exceptin"));
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
checkLocationPermission();
}
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
mGoogleClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mLocationRequest = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY)
.setInterval(60*1000)
.setFastestInterval(1*1000);}
并且在4月1日:
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
buildGoogleApiClient();
mMap.setTrafficEnabled(true);
mMap.setMyLocationEnabled(true);}
这是:
protected synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mGoogleApiClient.connect();
}
@Override
public void onConnected(@Nullable Bundle bundle) {
if (servicesAvailable()) {
// Get best last location measurement meeting criteria
mLastLocation = bestLastKnownLocation(MIN_LAST_READ_ACCURACY, FIVE_MIN);
if (null == mLastLocation
|| mLastLocation.getAccuracy() > MIN_LAST_READ_ACCURACY
|| mLastLocation.getTime() < System.currentTimeMillis() - TWO_MIN) {
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
// Schedule a runnable to unregister location listeners
Executors.newScheduledThreadPool(1).schedule(new Runnable() {
@Override
public void run() {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, MainActivity.this);//This Line Return Error
}
}, ONE_MIN, TimeUnit.MILLISECONDS);
}
}else{
handleNewLocation(mLastLocation);
}
}
protected synchronized void buildGoogleAppClient()受保护{
mgoogleapclient=新的Googleapclient.Builder(此)
.addConnectionCallbacks(此)
.addOnConnectionFailedListener(此)
.addApi(LocationServices.API)
.build();
mGoogleApiClient.connect();
}
@凌驾
未连接的公共无效(@Nullable Bundle){
if(servicesAvailable()){
//获得满足标准的最佳最后位置测量值
mLastLocation=BESTLASTKNOWNLLOCATION(最小上次读取精度,五分钟);
如果(null==mLastLocation
||mLastLocation.getAccuracy()>最小上次读取精度
||mLastLocation.getTime()
感谢您的帮助:)这是对我有效的完整实现
public class MainActivity extends AppCompatActivity implements
GoogleApiClient.OnConnectionFailedListener,
GoogleApiClient.ConnectionCallbacks,
LocationListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buildGoogleApiClient();
}
@Override
public void onConnected(@Nullable Bundle bundle) {
Log.d(TAG, "Connection established. Fetching location ..");
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(1000);
mLocationRequest.setFastestInterval(1000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
}
@Override
public void onLocationChanged(Location location) {
Log.d("Lat: " + location.getLatitude() + "Lng : " + location.getLongitude());
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
}
public synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(getBaseContext())
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mGoogleApiClient.connect();
}
@Override
public void onStart(){
super.onStart();
if(this.googleApiClient != null){
this.googleApiClient.connect();
}
}
@Override
public void onPause() {
super.onPause();
//stop location updates when Activity is no longer active
if (mGoogleApiClient != null) {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
}
}
}
在onCreate中,在没有客户端的情况下调用
getmapsync()
您需要在
onCreate
中调用mGoogleClient.connect()
,然后将mapFragment.getmapsync(this)
移动到onConnected
,解决了我的问题,因为我在我的项目中使用了闪屏,将此代码放入闪屏活动中:
mGoogleClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
感谢您快速响应,但问题尚未解决。异常是否仍然发生?您必须首先在oncreate()中创建
mGoogleClient
。是的,mGoogleClient在oncreate()中,但在onStart()中发生nullexception。。。
