        compileSdkVersion 25
        defaultConfig {
            applicationId "com.blogapp.anu.blogapp"
            minSdkVersion 19
            targetSdkVersion 25

            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }


    dependencies {
        implementation fileTree(include: ['*.jar'], dir: 'libs')

        implementation 'com.android.support:appcompat-v7:25.4.0'
        implementation 'com.android.support:recyclerview-v7:25.4.0'

        androidTestImplementation 'com.android.support.test:runner:1.0.1'
        androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'


    }

    apply plugin: 'com.google.gms.google-services'

Seems i'm using same version for all. And i already read some questions and apply them, but not work for me.

this is my project level

        // Top-level build file where you can add configuration options common to all sub-projects/modules.

    buildscript {

        repositories {
            google()
            jcenter()

        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.1.0'
            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
            classpath  'com.google.gms:google-services:3.2.1'
        }
    }

    allprojects {
        repositories {
            google()
            jcenter()
            maven {
                url "https://maven.google.com"
            }
        }
    }

    task clean(type: Delete) {
        delete rootProject.buildDir
    }

This is my Android SDK Platforms which i using right now

And in every instance in all of my classes where I reference R.id.something, the R is in red and it says "cannot resolve symbol R".

Anyone know what wrong with my codes?

Try to clean your project from build option in the android studio. — Rishabh Rawat, Apr 02 '18 at 05:52

check the library file you using might be they use different build tools version because of that also problem will happen. — Lingeshwaran, Apr 02 '18 at 06:06
What is the error exactly?. You are not able to run the project?. Or it's a warning saying a higher version is available . — Sunil Sunny, Apr 02 '18 at 06:08
The one having `(Project: project name)` on the right of the gradle file. — Mohammedsalim Shivani, Apr 02 '18 at 06:37

Solution 1:

if your doing some Major changes you need to Restart your Android Studios File->Invalidate caches/Restart

Solution 2: If you are using external libs:

Goto File -> Settings -> Compiler now check use external build clean and rebuild..

then rebuild project

Solution 3:

change into buildToolsVersion "25.0.3"

Add dependencies

    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support:design:25.3.1'

Can you please try replacing the 2 lines

 compile 'com.theartofdev.edmodo:android-image-cropper:2.6.0'
 compile 'com.firebaseui:firebase-ui-database:0.4.0'

with

 implementation 'com.theartofdev.edmodo:android-image-cropper:2.6.0'
 implementation 'com.firebaseui:firebase-ui-database:0.4.0'

Also, for R not being importing to your packages import statemt, yo can navigate to R keyword in your code and press Alt + Enter and then select import class from the menu.

@SahanPasinduNirmal Try navigating where you have occurence of "R" in your code and then enter `Alt+Enter`. Also you can try importing the statement yourself as `import com.blogapp.anu.blogapp.R;` – warezthief Apr 02 '18 at 07:33
