Gradle sync failed: Plugin with id 'com.android.application' not found - android

I have updated my Android Studio from 2.x to 3.x. At first it showed gradle sync failed, then I fixed it somehow with the help of Stack Overflow. In that process I updated gradle. It fixed for some time later by following the steps in the Stack Overflow post. I deleted one file in gradle, now this is came out:
Gradle sync failed: Plugin with id 'com.android.application' not found
Please any one tell me how to fix it.
here is the file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.demoandroid.udacitybdcard"
minSdkVersion 19
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-v7:25.1.0'
testCompile 'junit:junit:4.12'}

Running project on Android Studio fails because of missing app module

When I press on run in Android studio an Edit configuration windows pops up and says "Error: Module not specified".
I have added sources to the application libs folder by manually making a folder structure android/hardware/automotive/vehicle/V2_0 and copied the files in there.
Build completes without errors.
I haven't edited the MainActivity -class so it is all pre-generated code.
I believe this error has something to do with incorrect syntax when including but it seems to be hard to get it working :)
this is my settings.gradle file:
include ':app'
project(':app').projectDir = new File('libs/android/hardware/automotive/vehicle/V2_0')
and this is my build.gradle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.example.s26150.testingopencar"
minSdkVersion 21
targetSdkVersion 26
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-v7:26.+'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile project(":android.hardware.automotive.vehicle.V2_0")
testCompile 'junit:junit:4.12'
}
What could be the issue here?
thanks in advance.

Error:Invalid byte 1 of 1-byte UTF-8 sequence. in android studio

Getting below error in android studio.
Gradle sync failed: Invalid byte 1 of 1-byte UTF-8 sequence.
my gradle file is as below. i cannot find the solution. now the same error is getting in all my projects.
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "com.example.myapp"
minSdkVersion 19
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-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:recyclerview-v7:25.3.1'
testCompile 'junit:junit:4.12'
}
Got the same issue...
finally change my classpath in the project build.gradle ... for my case in example it was
com.android.tools.build:gradle:2.3.3
I first pass it to
com.android.tools.build:gradle:2.3.+
and once the gradle synced turn it back to
com.android.tools.build:gradle:2.3.3

I have click "install missing platforms and sync project",now,in my directory android-ndk-r13b/platforms/,i did have android-24.

buildToolsVersion "24.0.0"
defaultConfig {
applicationId "com.mimo520.arderbud.myfirstandroidapplication"

})
compile 'com.android.support:appcompat-v7:24.+'
testCompile 'junit:junit:4.12'
}
so how to fix this file? thanks!
Please, post your app's build.gradle (you've posted your project's build.gradle).
Often this problem is that you haven't current buildtools version, or your compile version doesn't match with the version of your buildtools and so on.

After import to android studio, gradle task “app:dexDebug” fails

I have the following gradle file in my android app:
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "com.example.test.forum"
minSdkVersion 16
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
//configurations {
// all*.exclude group: 'com.android.support', module: 'support-v4'
//}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:19+'
compile 'org.java-websocket:Java-WebSocket:1.3.0'
}
and the bug output is Error code: 2; Output: UNEXPECTED TOP-LEVEL EXCEPTION.
When I uncomment the configurations part of the file I get Can't find package v4 (support) although I have it installed from the sdk. Any ideas on how I can solve this?
