将GoogleApiClient传递给另一个活动

// 在当前活动中构建GoogleApiClient
private GoogleApiClient mGoogleApiClient;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // ...
    
    // 创建GoogleApiClient.Builder对象
    GoogleApiClient.Builder builder = new GoogleApiClient.Builder(this);
    // 添加所需的API
    builder.addApi(LocationServices.API);
    builder.addApi(Plus.API);
    // ...
    
    // 构建GoogleApiClient
    mGoogleApiClient = builder.build();
    
    // 连接GoogleApiClient
    mGoogleApiClient.connect();
}

// 在当前活动中传递GoogleApiClient给另一个活动
Intent intent = new Intent(CurrentActivity.this, AnotherActivity.class);
intent.putExtra("googleApiClient", mGoogleApiClient);
startActivity(intent);

// 在另一个活动中获取GoogleApiClient
private GoogleApiClient mGoogleApiClient;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // ...
    
    // 获取传递的Intent
    Intent intent = getIntent();
    // 提取GoogleApiClient对象
    mGoogleApiClient = intent.getParcelableExtra("googleApiClient");
    
    // 确保GoogleApiClient已连接
    if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
        // 可以使用GoogleApiClient访问Google Play服务的功能
        // 例如，获取用户的地理位置
        Location lastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
        // ...
    }
