最近我在手机上遇到了问题。我几乎每天和几天前都在研究logcat，我注意到logcat充满了一个例外。正是这个：
2019-05-26 11:23:19.034 14375-14441/? W/Bundle: Key android.icon expected Parcelable but value was a java.lang.Integer. The default value <null> was returned.
2019-05-26 11:23:19.034 14375-14441/? W/Bundle: Attempt to cast generated internal exception:

我还注意到，可能是因为这样，我的电池开始更快地耗尽电量。实际上，当我查看1周历史记录
时，Google Play服务在电池信息列表中的位置就很高如何确定哪个应用正在编写此异常？真的有可能吗？也许您还有其他解决办法？
