Android 用の 3D モデル ビューアー アプリを作成しています。モデルの表示と表示は OpenGL を介して C++ で記述されており、Android NDK を使用してこれを Android アプリとメッシュ化しています。ただし、アプリケーションをデプロイしようとすると、OpenGL コードを処理する多くのエラーが発生します。次に例を示します。

ここでのセットアップには明らかに何かが欠けています。Sequoyah (ネイティブ コードのコンパイルとデバッグ用) と NDK ver. r5b (Sequoyah はそれ以降のバージョンを認識できないため)。どんな提案でも歓迎します、私は絶望し始めています。
