問題は、クラッシュの根本的な原因を見つけるために私は私のコードの行数だけGoogle Codeの中にクラッシュログを必要とするということです。 、

しかしヌル オブジェクト参照に仮想メソッド「空iqe.a（ブール値）」を呼び出すために

試み：

私はこの方法でクラッシュをGoogleしようとしていますiqe.a(boolean)ではなく、isu.a(boolean)というメソッドでこのクラッシュが発生することがあります。

GoogleとStackOverflowには、このクラッシュやメソッドに関するコンテンツや情報がありません。

私はプロジェクト全体でこのメソッドを検索しようとしましたが、結果はありません。

私のプロジェクトのクラッシュログには何も書いていないので、問題が何であるかを分析することは非常に難しいと感じています。

は、クラッシュが発生した場合：
