Rendering Problems NOTE This project contains Java compilation errors which can cause rendering failures for custom views Fix compilation problems first

The following classes could not be instantiated:
- com.edmodo.cropper.CropImageView (Open Class, Show Exception)
 Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE  Exception Details org.xmlpull.v1.XmlPullParserException: name expected (position:START_TAG <null>@4:59 in java.io.StringReader@eb8d000)

my gradlie:

android {
    compileSdkVersion 19
    buildToolsVersion "19.1.0"

    defaultConfig {
        applicationId "com.example.android"
        minSdkVersion 16
        targetSdkVersion 19
        versionCode 1
