I got this error after an update of Android Gradle plugin and Android Studio.
I have checked this question (Android Studio build.gradle warning message), but I am not ab
Step by Step solution
1- Go to the build.gradle(module app)
2- In the dependencies, you will see the code like this
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.android.support:support-v4:23.3.0'
compile 'com.android.support:design:23.3.0'
3- Now you have to ONLY replace the compile with implementation and testCompile with testImplementation. Like this
implementation fileTree(dir: 'libs', include: ['*.jar'])
testImplementation 'junit:junit:4.12'
implementation 'com.android.support:appcompat-v7:23.3.0'
implementation 'com.android.support:support-v4:23.3.0'
implementation 'com.android.support:design:23.3.0'
4- That's all. Now click on Sync Now button.
Note- Don't change the number or version given specified in the code.
