This would most likely occur if a thread didn't catch an exception.
如果线程没有捕获异常，这很可能发生。
From the stack trace, I'd assume you're making a thread? Inside the run method, wrap everything inside a try block. Then log all Exception's.
从堆栈跟踪中，我假设你在做一个线程?在run方法中，将所有内容封装在try块中。然后记录所有异常的。
Example
例子
Thread myThread = new Thread(new MyRunnable());
myThread.start();
class MyRunnable extends Runnable
{
@Override
public void run()
{
try {
// Your code, where the exception was thrown
} catch (Exception ex) {
// Here we are logging the exception to see why it happened.
Log.e("my app", ex.toString());
}
}
}
