ファイアウォールユーザーの許可後許可アンドロイド

Question

私は少しアンドロイドに新しいです、そして、私は数日の間、今のソリューションを探しています。私は新しい6バージョンを使用してユーザーの場所を取得しようとしています - GoogleのAPIクライアントとユーザーのアクセス許可。私はアプリをインストールするとき、何も起こらないことが承認された後、許可ダイアログが表示されます（アプリは場所のトーストを表示する必要があります）。私は、アプリケーションを閉じて、それを再び開いて、私の指先を取得するとき。最初のインストールの後でトーストは動作しません。あなたは許可が付与された後mGoogleApiClient.connect();を呼び出す必要が
