java - 安卓 :Activity is blocking with black screen when it occur Exception

Question

如果我的代码有错误，Activity 将被黑屏阻止。但它不会抛出任何异常，仅在Android Monitor中抛出单行字。

11-09 17:03:03.984 14252-14262/? I/art: Starting a blocking GC HeapTrim
11-09 17:03:03.986 14252-14258/? I/art: Debugger is no longer active

在此Activity中，所有异常均未抛出。谁能告诉我为什么？

Answer 1

我自己捕获了异常。

Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(Thread thread, Throwable ex) {
    }
}
