If it derives from Application, add the fully qualified (namespace + class name) as the android:nameparameter of the application element in your manifest.
如果它派生自 Application，请android:name在清单中添加完全限定的（命名空间 + 类名）作为application 元素的参数。
<application
android:name="com.you.yourapp.ApplicationEx"
Or if the class' package can be described as relative to the packagein the manifesttag, then just start with a .:
或者，如果类的包可谓是相对package的manifest标签，那么就先从.：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.you.yourapp">
<application
android:name=".ApplicationEx"

but in case you are already using some library like branch.io's library then most probably your manifest
但是如果您已经在使用诸如 branch.io 的库之类的库，那么很可能是您的清单
<application name="">
<application name="">
property will already have some name like
属性已经有一些名称，如
`<application name="io.referral.BranchApp">
in that case you need to first extend your application class, like below:
在这种情况下，您需要首先扩展您的应用程序类，如下所示：
public class Application extends BranchApp
and then register your application in manifest as:
然后在清单中将您的应用程序注册为：
android:name="absdevelopers.com.brankreferal.Application"
this works perfectly for me :) i hope it helps someone in trouble :)
这对我来说非常有效:) 我希望它可以帮助遇到麻烦的人 :)

If you are using a MultiDex application you will already have "android:name" in use so instead extend android.support.multidex.MultiDexApplication:
如果您使用的是 MultiDex 应用程序，您将已经使用了“android:name”，因此请改为扩展android.support.multidex.MultiDexApplication：
public class MyApplication extends MultiDexApplication {...}
And add it to the Android manifest:
并将其添加到 Android 清单中：
android:name="app.package.MyApplication"
