パブリックボイドのonLocationChanged（ロケーションロケーション）を使用してGoogleマップ上のユーザーのパスをトレースするアプリケーションを作成しようとしていますが、クラッシュします。ここに私のコードです..あなたが修正する必要があるものがあれば教えてください。ありがとう！Google Apiクライアントとロケーションリスナーの実装中にアプリケーションがクラッシュする

、あなたがGoogleAPI前に場所にアクセスしようとしているようで、私のMapsActivity.javaファイルですクライアントが接続されています。

したがって、接続時に場所を要求する必要があります。同じことが実装できます。

if(mGoogleApiClient.isConnected()) { 
      LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this); 
     }

それともは方法をonConnected位置情報の更新を要求することができます。

@Override 
public void onConnected(@Nullable Bundle bundle) { 
    LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this); 
}

あなたは、私がテストした完全なコードを見つけ、私が言ったことを行っていない： 行番号103と行番号を参照してください179

私はmGoogleApiClient.connect（）を追加しました。私のonStart（）メソッドに渡して、LocationServices.FusedLocationApiを呼び出しようとしました。requestLocationUpdates（mGoogleApiClient、mLocationRequest、this）;アプリが再びクラッシュした。上記のコードを新しいスタックトレースとMapsActivity.javaファイルで更新しました。どう考えているか教えてください！ –

onConnectedメソッドでFusedLocation.requestLocationUpdatesをリクエストしましたか？あなたのアプリがまだクラッシュした場合、完全なクラッシュログをコメントとして入力してください。 –

はい、私はonConnectedメソッドでFusedLocation.requestLocationUpdatesを要求します。私のクラッシュログは以下のコメントにあります –

はこれを試してみてください。この方法を使用してoncreate()で googleApiクライアントonstart()ではなくoncreate()

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

そしてInitilizeで接続し、GoogleのAPIクライアントにと（のonCreateで呼び出す）

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

はありがとう役に立てば幸いすべての助けのために、私は私の問題を把握することができました。問題は、oCationServices.FusedLocationApi.requestLocationUpdates（mGoogleApiClient、mLocationRequest、this）というonConnected（）メソッドを使用していないことでした。が呼び出されます。今私はすべての変更を行った！
