In Android 9 likely to help adding to manifest into "application" tag:
在 Android 9 中可能有助于将清单添加到“应用程序”标签中：
<uses-library
android:name="org.apache.http.legacy"
android:required="false" />

In some cases, this could be a MultiDex issue. Try this in your application class. That is in App.javawhich extends Application:
在某些情况下，这可能是 MultiDex 问题。在您的应用程序类中试试这个。那就是App.java其中扩展Application：
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this); // this is the key code
}

if you already added multidex in both gradle and manifest then try to disable instant run and then create apk to test, i was facing same issue and searched a lot and tried every solution but at last this solved my problem
如果您已经在 gradle 和 manifest 中添加了 multidex 然后尝试禁用即时运行然后创建 apk 进行测试，我遇到了同样的问题并进行了大量搜索并尝试了所有解决方案，但最后这解决了我的问题
