Error:The value of attribute “android:name” associated with an element type “null” must not contain the '<' character

Question

I am a novice trying to figure out the error. But I have reached upon no solution even after trying it several times.

I am sharing the android-manifest.xml file code. More details are after this code.

    </manifest>

So, what I am trying to do here is to integrate a chat feature in a small time-stopper app that I just created for the learning purpose and I am integrating it also for the learning purpose.

When I build gradle,Result shows Error:The value of attribute "android:name" associated with an element type "null" must not contain the '<' character.

and

Error:Cannot read packageName from C:\\Users\\APnaturals\\AndroidStudioProjects\\TimeStopper\\app\\src\\main\\AndroidManifest.xml

When I replace APP_PKG_NAME with the one mentioned in here

manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.home.timestopper"

Gradle Build fails again without giving any cause.

Answer 1

  <category android:name="<APP_PKG_NAME>" /> 

您似乎忘记了在此元素中配置软件包名称。

Answer 2

只需从元数据中删除APP_PKG_NAME ，然后输入您的包名称或ID即可，如androidmanifest.xml中不允许<> 。
