compile 'com.ogaclejapan.arclayout:library:1.0.1#aar'
compile 'com.github.asyl.animation:arcanimator:1.0.0'
but i give this error message
cannot resolve symbol'SupportAnimator'

in import line
import io.codetail.animation.SupportAnimator;
import io.codetail.animation.ViewAnimationUtils;
and its strange because i do not give this error in this lines
import io.codetail.animation.arcanimator.ArcAnimator;
import io.codetail.animation.arcanimator.Side;
which is in same library.
can anyone help me about that?

You have to use other dependency to use Support Animator say https://github.com/kedzie/Support_v4_NineOldAndroids. Support Animator is not there in the package of the library that you have used. It’s not showing inside the package you have used, you can check at https://github.com/asyl/ArcAnimator/tree/master/animator/src/main/java/io/codetail/animation/arcanimator.
Also you can take help of some samples given here at https://github.com/ozodrukh/CircularReveal/releases.

Cannot find Log class in Android

I am developing an app in Android Studio with target for API 22. I have tried to use the Log class with the method d() but I did not find it. The helper shows only Log()...
What am I missing?

Just import the library import android.util.Log;
And just tips: use alt+space and alt+enter feature from Android Studio
Note:
Alt + Enter = Project quick fix (show intention actions and quick fixes)

IBM Worklight - How do I enable WebView debugging in Android?

Since Chrome has an awesome feature for remote debugging,
I am wondering how this could help in developing in Worklight.
In the following docs they say to debug the contents of your WebView, you need to enable it programmatically from within your application by calling setWebContentsDebuggingEnabled, a static method on the WebView class.
Where can I find this class and will this be beneficial to do it in Worklight?
https://developers.google.com/chrome-developer-tools/docs/remote-debugging?hl=nl#debugging-webviews

Please note that WebView debugging is only relevant for Android 4.4 "KitKat" and not to any prior version of the Android OS.
To debug your Chromium WebView in a Worklight application with the Android environment,
Open the Android SDK and update to API Level 19.
You will of course need either a device or emulator running this version.
Make sure that in yourAppName\android\native\AndroidManifest.xml you add support for targetSdkVersion=19.
<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="19" />
Change the Build Target to Android 4.4:
Right-click on the generated Android project > Properties > Android > Build Target
Open yourAppName\android\native\src\com\yourAppName\yourAppName.java and
Import the following:
import android.os.Build;
import android.util.Log;
import android.content.pm.ApplicationInfo;
import android.webkit.WebView;
Add the following to the onCreate() function:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
if(0 != (getApplicationInfo().flags & ApplicationInfo.FLAG_DEBUGGABLE)){
WebView.setWebContentsDebuggingEnabled(true);
}
}
The rest of the steps are as described in the Google documentation page.
I don't have an Android device to verify this, so please try.
As for whether it is beneficial or not, another debugging alternative can't hurt. It is up to you to decide if it's good or not, for you.

android import error

I am trying use the GPE code for App-Android Android-App communication. Both the two new created folders (Android, AppEngine) have errors. I think the problem is that there are
errors with the packages:
import com.google.web.bindery.requestfactory.shared.InstanceRequest;
import com.google.web.bindery.requestfactory.shared.Request;
import com.google.web.bindery.requestfactory.shared.RequestContext;
import com.google.web.bindery.requestfactory.shared.RequestFactory;
import com.google.web.bindery.requestfactory.shared.ServiceName;
It says "The import com.google.web cannot be resolved." I tried adding everything able to be checked checked in the build path. I also know I installed the Web Toolkit and everything. What is wrong?
Statements like the following also have error markings:
#ProxyForName(value = "com.glm.server.Message",
locator = "com.glm.server.MessageLocator") and actually there are so many errors it must be the imports.
