Error while porting app from Eclipse to Android Studio

Solution 1
You'll have to re-add all your dependencies, including appcompat.
If you have all the jars, you can put them in the libs/ directory of the app when using a dependency like this in the app's build.gradle (projectdir/app/build.gradle):
compile fileTree(dir: 'libs', include: ['*.jar'])
The other and preferred option is to declare dependencies in Maven-coordinates, like below (excerpt from the app's build.gradle file):
dependencies {
compile 'com.android.support:appcompat-v7:19.1.0'
compile 'com.google.android.gms:play-services:4.2.42'
compile 'org.apache.commons:commons-lang3:3.2.+'
}
Solution 2
I apparently screwed up the project perhaps because of the project identifier. Now I copied exactly the one I had in Eclispe and at least now the errors are a bit friendlier. Of course I first had to add to build.gradle:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.gms:play-services:+'
compile 'com.android.support:appcompat-v7:20.+'
}
I will be back at you if I am not able to understand the reason for the new errors, now apparently mostly affecting the references to R resources and the GCMRegistrar. For tonight, anyway, I am happy enough.
Solution 3
Missing dependencies{} causes this error.
dependencies {
compile "com.android.support:support-v4:23.1.1"
compile 'com.android.support:support-annotations:23.1.1'
}

I am in the process of porting a project from Eclipse to the latest Android Studio. All went fine by copying all the files in the directory used by AS but I get a host of errors practically on all the libraries I use and the imports from my own project: what may be the problem? This is the list of errors: (of course the unfound symbols are fine and kicking in the project).
