问题是，为了找到崩溃的根本原因，我需要在我的代码中添加一个行号，但崩溃日志只记录在 Google 代码中。

我试图用谷歌搜索这个方法的崩溃：

尝试在 null 上调用虚拟方法“void iqe.a(boolean)” 对象引用

但是，有时使用方法 isu.a(boolean) 而不是 iqe.a(boolean) 会发生此崩溃。

Google 和 StackOverflow 没有关于此崩溃或方法的任何内容/信息。

我尝试在整个项目中搜索此方法，但没有任何结果。

由于崩溃日志中没有我的项目中的任何一行，我觉得很难分析出问题所在。

发生崩溃时：

1. 播放视频，新活动打开。 > 按返回按钮。
2. 重复步骤 1 10-20 次。

Answer 1

在 backpress 方法中使用意图

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