连接到 Google Api 客户端时连接失败

Question

我尝试连接到 Google API 客户端以在我的应用程序中实现一些功能。但由于某种原因，我无法连接到 Google API 客户端，因此我无法继续使用 Google 服务。

在我初始化 GoogleApiClient 之后，我检查 mGoogleApiClient.isConnected 是否总是得到 False，我不知道为什么。我将不胜感激任何帮助。谢谢。

请注意，一切都发生在后台服务上。

public class Background extends Service implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, ResultCallback<Status> {

private String TAG = "Background";

private GoogleApiClient mGoogleApiClient;
@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {


    Log.e(TAG,"Start");


    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(ActivityRecognition.API)
            .addApi(LocationServices.API)
            .build();

    if (!mGoogleApiClient.isConnected()) {
        Log.e(TAG,"GoogleApiClient not yet connected");
    } else {
        Log.e(TAG,"GoogleApiClient connected");

    }

    return Service.START_STICKY;
}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
    Log.e(TAG, "Connection failed. Error: " + connectionResult.getErrorCode());

}

@Override
public void onResult(Status status) {
    if (status.isSuccess()) {
        Log.e(TAG, "Successfully added activity detection.");

    } else {
        Log.e(TAG, "Error: " + status.getStatusMessage());
    }
}

@Override
public void onConnected(Bundle bundle) {
    Log.i(TAG, "Connected");
    mGoogleApiClient.connect();
}

@Override
public void onConnectionSuspended(int i) {
    Log.i(TAG, "Connection suspended");
    mGoogleApiClient.connect();
}

Answer 1

您没有在正确的地方调用 .connect()。您正在构建客户端，之后必须调用 .connect() 。您正在立即检查它是否已连接，它永远不会连接。

请在 .onStartCommand() 中的 .build() 之后添加 .connect() 并删除此代码：

if (!mGoogleApiClient.isConnected()) {
    Log.e(TAG,"GoogleApiClient not yet connected");
} else {
    Log.e(TAG,"GoogleApiClient connected");
}

此外，请删除它，因为它可能会让您处于不想要的状态：

@Override
public void onConnected(Bundle bundle) {
    Log.i(TAG, "Connected");
    // remove this -> mGoogleApiClient.connect();
}

Answer 2

在您的服务 onStartCommand 中连接 googleApiClient

@Override
public int onStartCommand(Intent intent, int flags, int startId) {


Log.e(TAG,"Start");


mGoogleApiClient = new GoogleApiClient.Builder(this)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .addApi(ActivityRecognition.API)
        .addApi(LocationServices.API)
        .build();

  if (!mGoogleApiClient.isConnected()) {
    Log.e(TAG,"GoogleApiClient not yet connected");

    mGoogleApiClient.connect(); // connect it here..

  } else {
    Log.e(TAG,"GoogleApiClient connected");

}

return Service.START_STICKY;

}
