私は簡単なAndroidゲームを開発していますが、テスト中に問題に遭遇しています。 Lenovo Tab3 7タブレット（Android 5.0.1）またはLG P880電話（Android 4.0.3）で動作させるとうまく動作します。私はサムスンS7携帯電話（アンドロイド7.0）のゲームでそれを実行すると正常に動作します。私が意味することは、何も問題なく連続して10回実行できるということですが、ゲームが5〜30秒間停止するか、応答が停止することがあります。これは、通常、新しいアクティビティの開始時またはその直後に発生します。シンプルゲームはタブレットで動作しますが、時々電話に遅れます
ゲームレイアウトとしてSurfaceViewを長時間使用4 Activitiesを有しています。すべてのSurfaceViewsはRunnableを実装しています。アクティビティ：スプラッシュ画面（noHistory =マニフェストの「true」）、メニュー、難易度の選択とゲーム。
私はmdpi drawablesしか使用せず、すべての画面サイズに比例して調整します。ビットマップはBitmapFactory.decodeResourceを使用してロードされ、BitmapFactory.OptionsinDensity = 1,inScaled = falseとなります。
問題が発生すると、logcatはガベージコレクションのみを表示します。場合によっては、ゲームが5〜30秒間「一時停止」（タップが登録されていない）して正常に再開します。応答がないために再起動する必要があることがあります。私はゲームが何らかの理由で入力を収集しなくなったように感じます。入力はonTouchEventを無効にして、ACTION_UPがタップされた画像範囲内にあるかどうかをチェックすることによって処理されます。私が言ったように、これはタブレットやP880ではなく、S7（2台の電話機で試してみました）でしか起こらないので、Nougatまたは私には電話の下でdensityを強制することが考えられます。この原因と私はAndroidのゲーム開発に新しいもの
だから、私はアイデアを実行しているので、何をすることができ、誰もが/私は解決策を探してしなければならない任意のアイデアを持って知っているのですか？ Nougat特有の設定/確認が必要ですか？強制的なピクセル密度はデバイスのパフォーマンスに何らかの影響を及ぼしますか？

あなたはlogcatを意味しますか？もしそうなら、いいえ。ゲームが停止したときに私が言ったのは、ログに表示されている唯一のものであるという意味のGCメッセージだけでした。ゲームがうまくいっている間にGCのメッセージがログに記録されていることに気がついたので、GCを停止しているのはそれだけだとは思わない。 – Dragan
