こんにちは、男の子/ gals java neanderthalが再びひっくり返ります。私は大学の最終プロジェクトの一環としてアンドロイドアプリを作っています。このアクティビティは約3回のアクティビティで、カメラ/ギャラリー（これは正常に動作しています）から写真を撮影した後のサムネイル画像ビューアです。問題は、私が最終的に写真と一緒にデータベースに送るgpsコーディネートを表示することです。私は致命的なエラーを処理していない実行時のアクセス許可（API 23 +）のために私は答えを見つけて、それは大丈夫だと思った。しかし、私はクラッシュやエラーを生成していないが、私はアクセス権を探してダイアログボックスを取得していない、または私はアクセス許可を持っているかどうか私に言って乾杯。私はまた、値のテキストビューでテキストを設定することはできません。私はあなたが私に与えることができるすべての助けに感謝します。前もって感謝します！ package com.example.gary.natureallv2;Android gpsの権限
