Android Question

Cannot resolve symbol appCompatActivity on create of new project in Android Studio?

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

buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

allprojects {
repositories {
jcenter()
}
}

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


module level gradle:

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
defaultConfig {
applicationId "in.co.persistent.gamedisappear"
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.0.1'
testCompile 'junit:junit:4.12'
}


`
The error I getI know this question is asked many times.But I have tried various things like invalidate/restart cache.Also tried restarting android and building new project.Plus added the required dependencies (compile 'com.android.support:appcompat-v7:25.0.1') Nothing works!

Answer

From the gradle build error screenshot it is clear that problem is Could no resolve junit:junit:4.12
Solution- If you do not need to run unit test cases then you comment following line testCompile 'junit:junit:4.12' and check
but if you need it then please add following codes in module level build.gradle file

repositories {
      jcenter()
      maven { url 'http://repo1.maven.org/maven2' }
    }
