的問題是，爲了找到墜毀的根本原因，我需要在我的代碼行數，但崩潰日誌中只有谷歌代碼。

我試圖google一下碰撞在該方法中：

嘗試調用虛擬方法「無效iqe.a（布爾值）」上的空 對象引用

然而，這種崩潰有時發生在方法isu.a(boolean)而不是iqe.a(boolean)。

Google和StackOverflow沒有關於此崩潰或方法的任何內容/信息。

我試圖在我的整個項目中搜索此方法，但這不會導致任何結果。

由於崩潰日誌沒有來自我的項目的任何行，我覺得很難分析是什麼問題。

當崩潰發生時：

1. 播放視頻，新的活動打開。 >按返回按鈕。
2. 重複步驟1 10-20次。在backpress方法

Answer 1

使用意圖

Intent intent=new Intent(Playlist.this,MainActivity.class); 
    startActivity(intent); 
    finish();
