Gradle tasks : Error:(1, 10) fatal error: 'PTPAppDelegate.h' file not found

While running my project this error has showed up. I didn't find the solution to this problem. I've got overwhelmed. THIS IS MY GRADLE FILE:

apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
applicationId "net.mobilegts.candyjump"
minSdkVersion 14
targetSdkVersion 23
ndk {
moduleName "player_shared"
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
externalNativeBuild {
ndkBuild {
path 'Android.mk'
}
}
}

dependencies {
compile 'com.google.android.gms:play-services:+'
compile files('libs/dagger-1.2.2.jar')
compile files('libs/javax.inject-1.jar')
compile files('libs/nineoldandroids-2.4.0.jar')
compile files('libs/support-v4-19.0.1.jar')
}
THIS IS MY Android.mk FILE I've linked my project and done some changes :

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)



LOCAL_MODULE := player_shared
LOCAL_LDFLAGS := -Wl,--build-id
LOCAL_SRC_FILES := \

LOCAL_C_INCLUDES += C:\Users\DELL\Desktop\android\app\src\main\jni

include $(BUILD_SHARED_LIBRARY)
