根据anr日志是ViewModel里面的问题 viewModel clear时有一把锁 不使用viewModel 直接依赖仓库就好了
怀疑是流close的时候有问题 但是都是用的lifeCyleScope
viewModel clear 源码
@MainThread
final void clear() {
mCleared = true;
// Since clear() is final, this method is still called on mock objects
// and in those cases, mBagOfTags is null. It'll always be empty though
// because setTagIfAbsent and getTag are not final so we can skip
// clearing it
if (mBagOfTags != null) {
synchronized (mBagOfTags) {
for (Object value : mBagOfTags.values()) {
// see comment for the similar call in setTagIfAbsent
closeWithRuntimeException(value);
}
}
}
// We need the same null check here
if (mCloseables != null) {
synchronized (mCloseables) {
for (Closeable closeable : mCloseables) {
closeWithRuntimeException(closeable); 怀疑是这里耗时了
}
}
}
onCleared();
}
