当没有互联网连接时,Google API客户端连接方法会冻结用户界面

Question

我在文档中读到connect方法"立即返回,并在后台连接到服务".但我认为情况并非如此,至少对我而言.

我甚至为connect方法创建了一个单独的线程,但是每次调用UI时仍然会冻结onStart方法(我正在尝试连接).

注意:只有在没有互联网连接时才会发生这种情况.

那么我该如何解决这个问题呢？谢谢

就像上面说的检查你是否有互联网连接..!!

 private void CheckConnection() {

        ConnectivityManager cm = (ConnectivityManager) getApplicationContext()
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
        if (null != activeNetwork) {
            if(activeNetwork.getType() == ConnectivityManager.TYPE_WIFI)
                answer="You are connected to a WiFi Network";
            System.out.println(answer);
            if(activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE)
                answer="You are connected to a Mobile Network";
        }
        else
            answer = "No internet Connectivity";
        Toast.makeText(getApplicationContext(), answer, Toast.LENGTH_LONG).show();
    }

在清单文件中添加

 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-feature android:name="android.hardware.location.gps" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

如果在活动中

@Override
    protected void onStart() {
        super.onStart();
        if (!googleApiClient.isConnecting() || !googleApiClient.isConnected()) {
            googleApiClient.connect();
        }
    }

和Oncreate 函数中

 //Initializing googleApiClient
        googleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
        googleApiClient.connect();

在 Service 类中对Oncreate执行上述操作。
