我过去制作过一些应用程序，但都没有这个问题。它在Android Studio中进行调试时有效，但是如果我停止调试并尝试直接从手机中打开应用程序(已通过调试将其安装后)，我会收到“[应用程序名称]”已停止工作的信息”

最佳答案
我必须用困难的方式做，并注释掉MainActivity上的所有内容，然后逐行取消注释1行，安装apk，然后从我的手机打开以查看引起错误的行，这就是:
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
//TODO: Open activity specified in key `click_action`
// THE CULPRIT:::Apparently you cannot have log statements in the app when not debugging?
// Because bundle.getString("click_action") works.
Log.println(Log.ASSERT, "Click Action: ", bundle.getString("click_action"));
}
