Question

我正在尝试调试我们正在修改的供应商的Android应用程序以满足我们的需求，因此它不是我们的代码，问题不足以让他们修复。它正在Galaxy Tab 10.1上崩溃（在模拟器和Galaxy Nexus上正常运行），但每当应用程序崩溃时，我都无法获得完整的堆栈跟踪。它总是在行中间切断：at java.lang.reflect.Constructor.constructNative(Native M。注意它甚至会阻止中间词。

我还直接从设备抓取了日志文件，它们显示相同的截止。

我可以看到它与GradesListAdapter.getView有关。调试和步入该行会导致Android系统代码。

什么可能导致Android在其输出中停止中线？是否有其他方法来调试可能会产生更好结果的应用程序？

Answer 1

如this answer所述，单个logcat消息的大小约为4076字节。

在您的情况下，相关行已经在logcat输出中：

android.widget.ArrayAdapter.createViewFromResource（ArrayAdapter.java:371）at android.widget.ArrayAdapter.getView（ArrayAdapter.java:362）at com.ellucian.mobile.android.grades.GradesListAdapter.getView（GradesListAdapter.java:99）

显示您用于GradesListAdapter的布局是问题的根源。

Android logcat停在中线
