Google Api Client sometime NULL in onConnected

Question

I implement GoogleApiClient as bellow:

 mGoogleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this, 0 /* client         


        

Answer 1

build() calls onConnected immediately if you are already connected. Therefore, your variable might be null.

Better use

mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this, 0 /* clientId */, this)
            .addApi(LocationServices.API)
            .addApi(Places.GEO_DATA_API)
            .addConnectionCallbacks(this);
mGoogleApiClient.build();

Answer 2

I had the same problem. All I did to solve it is remove .enableAutoManage(this, 0 /* clientId */, this) because it just doesn't work properly from what I assumed. Then, override these methods in your activity:

@Override
public void onStart() {
    super.onStart();
    if (mGoogleApiClient != null) {
        mGoogleApiClient.connect();
    }
}

@Override
public void onStop() {
    if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
        mGoogleApiClient.disconnect();
    }
    super.onStop();
}

Technically, that is what .enableAutoManage(this, 0 /* clientId */, this) was supposed to do, except that now, everything works as it should.

Answer 3

If u are facing this problem when u try to reinitialize mGoogleApiClient, then just remove

.enableAutoManage(this, 0 /* clientId */, this)

Use

mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(LocationServices.API)
            .addApi(Places.GEO_DATA_API)
            .addConnectionCallbacks(this)
            .build();

and it will work fine

I think you'd better watch this reference.

reference page of "public GoogleApiClient.Builder enableAutoManage"

In this page shows that, through IllegalStateException if clientId is already being auto-managed. So, check on your code with

                .enableAutoManage(this, 0 /* clientId */, this)

I think if exception on your code, it could return zero as not completed.

Answer 5

I had the same problem (Already managing a GoogleApiClient with id 0) in a fragment, and finally I resolved it :

• Override onStart() and onStop() normally
• Add in onStop() call yourApiGoogle.stopAutoManage(context);

Have a nice day...

Answer 6

Documentation says: At any given time, only one auto-managed client is allowed per id. To reuse an id you must first call stopAutoManage(FragmentActivity) on the previous client.

What I personally do is making a call to bellow method before I leave the activity, in which I am using the Google Api Client.

private void stopAutoManage() {
    if (mGoogleApiClient != null)
        mGoogleApiClient.stopAutoManage(mActivity);
}
