私はこのjava.lang.IndexOutOfBoundsExceptionの問題を抱えていますが、私のコードでトレースしたいのですが、Androidスタジオで問題がどこで始まるかを確認するのに十分なバックスタック（Debug and Logcatタブ） 。私は表示されたデバッグ情報のサイズを増やしたいが、どうやってそれを行うのか分からない。Androidスタジオでデバッグを増やす（logcat？）
私はすでにここに示す2つの方法を試みました：Android Studio logcat history/buffer sizeしかし、彼らは動作していないようです、私はいつも同じデバッグ情報を得ています。
