Error with android.support.v4 library
I'm trying to use the Android Skype SDK sample code in my project and I'm getting loads of errors saying android.support.v4 not found.
The android-support-v4.jar file is already in my libs folder.
I've followed other articles and tried to remove and add again but no success. Can anyone help me here please?
My gradle file

Answer
i'm getting loads of errors saying android.support.v4 not found.
Looks like you excluding compiling it.
configurations {
all*. exclude group: 'com.android.support', module: 'support-v4'
all*. exclude group: 'com.android.support', module: 'support-annotations'
}
Try removing that block.
The android-support-v4.jar file is already in my libs folder
You don't need a jar file, these lines (yes, all three) each include the support-v4 library.
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.1.1'
compile 'com.android.support:support-v4:23.0.1'
Really, though, you only need the design one. You can remove the other two. If you keep them, you have to make the version numbers the same, though.
One more thing - When you have compile fileTree(dir: 'libs', include: ['*.jar']), you do not need to use any lines containing compile files('libs/blah.jar') because the first way already grabs all the jar files.
