Android通过崩溃日志中控件id定位崩溃位置的方法

Posted 2022-11-01 Vigibord

问题

有时候我们获取到的崩溃日志中没有明确的哪个自定义类发生崩溃，有效信息只有系统的类或者某个控件类，这样我们就无法定位到具体的崩溃位置，比如下面这个崩溃：

java.lang.IllegalStateException: The content of the adapter has changed but
ListView did not receive a notification. Make sure the content of your adapter
is not modified from a background thread, but only from the UI thread. [in
ListView(2131559894, class android.widget.ListView) with Adapter(class
android.widget.HeaderViewListAdapter)]

上面这个崩溃就不能明显的显示出崩溃位置，但是还是透露了蛛丝马迹给我们查找，看这里[in ListView(2131559894, class android.widget.ListView) with Adapter(class android.widget.HeaderViewListAdapter)]，标红的一串数字就是该listview的id，从源码中可以看到：

                throw new IllegalStateException("The content of the adapter has changed but "
                        + "ListView did not receive a notification. Make sure the content of "
                        + "your adapter is not modified from a background thread, but only from "
                        + "the UI thread. Make sure your adapter calls notifyDataSetChanged() "
                        + "when its content changes. [in ListView(" + getId() + ", " + getClass()
                        + ") with Adapter(" + mAdapter.getClass() + ")]");

解决办法

得到控件的数字id后如何反推出控件的具体使用位置呢？因为每次编译之后R文件都是临时生成的，所有的id都是会变的，所以需要两个原材料：
A． 找到该崩溃对应的app版本，拿到apk包；
B． 一个合适的反编译工具，这里推荐jadx，绿色快速。连接http://download.csdn.net/detail/zhaoshuyu111/9749253

反编译后在resources.arsc中搜索数字id，通过其对应的有意义的字符串id，就能定位到崩溃位置了；
