however it says my packages(en, company, android, name) are unresolved, and so is the class inside of it.

<receiver android:name="en.company.android.name.SimpleWakefulReceiver" android:permission="com.google.android.c2dm.permission.SEND">

This looks like your functional directory is not correct and you can not find the build directory. You can do this:

1. If it is eclipse you can rebuild a new android project your java lowest level package copied to the new package

2. If android studio is simple, the path to src in gradle points to the underlying package, like this

   android {
   compileSdkVersion 19
   buildToolsVersion '25.0.0'
   ......
   sourceSets {
   main { manifest.srcFile 'AndroidManifest.xml'
   java.srcDirs = ['src/java']
   ......
   }
   ......
   }
   }

For me I had recently changed a typo in my package name/file folder and after that my activities could not be found. Thought I'd fixed it everywhere but I'd missed fixing it in my .idea/workspace.xml ... once I fixed it there I restarted android studio did a clean and build and then I was up and running again.
