I am developing an app using Fused Location Provider. I am getting an error "Unfortunately, appname has stopped" when i attempt to run the program. Eclipse doesnt show that there are any mistakes but there are errors in the logcat. I dont know how to fix them. I downloaded source code here. Please help me to understand what I did wrong?

Since your exception is:
ClassNotFoundException: Didn't find class "com.kpbird.fusedlocation.MainActivity"
into your AndroidManifest.xml
add the complete package were your activity is located:
<activity
android:name="com.kpbird.fusedlocation.MainActivity"
or be sure to have to correct package name defined:
package="com.kpbird.fusedlocation"
I think you typed incorrectly the package of your application in some place of your code!
In my case the issue was with gradle
I refactored my code from java to kotlin but forgot to add this in Gradle
apply plugin: 'kotlin-android'
This happened when I moved an app from one directory to another once, if @Jorgesys's solution doesn't help, consider renaming the module and cleaning the project. Note: I was using Android Studio.
