問題はonCreate（）が呼び出されていないことです！私は本当に原因は分かりませんが、Log.d（）はonCreate（）とonSurfaceCreated（）で呼び出されていないことがわかります。私はAndroidのゲーム2011のコードは、例えば、ここで始まり呼ば読んでいます帳から三角形を作るためのOpenGL ESを使用しようとしています：ここでhttp://beginning-android-games.googlecode.com/svn/trunk/ch07-gl-basics/Android onCreateが呼び出されていませんか？
は私のコードです：

なぜメインにランチャーアクティビティがありますか？ – user936414
@ user936414これはちょうどその方法で生成されたものであり、確かではありません。私はMAINクラスと関係があると思っていましたが、そうではないようです。それはいつもうまくいっていて、私はOpenGLで動作しないローディング画面でテストしました...だから私はそれが問題だとは思っていません。 – Zeveso
