Why android studio give an error when i add dependency?

I'm building a face detection Android app. When I add dependency inside the app/build.gradle it gives me an error. Here is my gradle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
buildToolsVersion "28.0.3"
defaultConfig {
applicationId "com.example.android.emojify"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support ', module: 'support-annotations'
})
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.google.android.gms:play-services-vision:10.2.0'
testImplementation 'junit:junit:4.12'
}
Error is reported in the following lines:
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:appcompat-v7:28.0.0'

Show us a screenshot of your error or format your error to easier reading, just click code button and paste it.
Edit: thank you :)
I think you should use refresh gradle after any changes in gradle.build and maybe you got this error because your build tools sdk is 28.0.3 and you want to use tool from sdk 28.0.0, just change compile sdk to 28.0.0 and click sync gradle on actionbar.

Your buildToolVersion is greater than your design and appcompat-v7.
Try to change,
implementation 'com.android.support:design:28.0.3' //or greater than 28.0.3
implementation 'com.android.support:appcompat-v7:28.0.3' //or greater than 28.0.3
connect to the internet and then build your project. Problem will be solved.

Failed to resolve: com.android.support:appcompat-v7:28.+ , Error: more than one library with package name 'android.support.graphics.drawable'

I'm new to Android Studio, I tried everything to solve this problem "Failed to resolve: com.android.support:appcompat-v7:28.+ "
I tried to clean project , invalidate cash/restart and removing .idea and still the same
I'm using android studio 2.2.1 for a learning reason , and I updated it to android studio 3 and there a multiple rendering problems so I returned back to version 2.2.1
I tried to add
maven {
url 'https://maven.google.com/'
name 'Google'
}
So,It stuck with another problem
"Error:Execution failed for task ':app:processDebugResources'.
> Error: more than one library with package name 'android.support.graphics.drawable'"
Error Photo
Finally I tried to change "appcompat-v7:28.+" to "appcompat-v7:27" and it' works but still tell me that i should use the same library to avoid mistakes
This is my Gradle code:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
buildToolsVersion "28.0.1"
defaultConfig {
applicationId "com.example.aimlive.myapplication"
minSdkVersion 15
targetSdkVersion 28
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-v7:28.+'
testCompile 'junit:junit:4.12'
}

Replace 'com.android.support:appcompat-v7:28+' by 'com.android.support:appcompat-v7:28.0.0'
and add below dependencies
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'

try adding this to your code:
repositories {
jcenter()
maven { // <-- Add this
url 'https://maven.google.com/'
}
}
Update: Now you moved on to another error:
Error: more than one library with package name 'android.support.graphics.drawable ...
To fix this, you need to change compile to implementation in dependencies part.

if you are using
compileSdkVersion 28
add in your dependencies below code
implementation 'com.android.support:appcompat-v7:28.0.0-alpha'
this is the link

Try this one, hope it is working
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
dependencies
classpath 'com.android.tools.build:gradle:3.1.4'
android
compileSdkVersion 28
minSdkVersion 21
targetSdkVersion 28

Try this code, hope it will be working. Thanks
build.gradle (Project)
dependencies {
classpath 'com.android.tools.build:gradle:3.1.4'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
build.gradle (app)
android {
compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
applicationId "YOUR_PACKAGE_NAME"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
renderscriptTargetApi 19
renderscriptSupportModeEnabled true
// Enabling multidex support.
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
lintOptions {
abortOnError false
}
}
dependencies check for implementation
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
}

I found that 'com.android.support:animated-vector-drawable' and 'com.android.support:support-vector-drawable' have a same package name in support library version 28.0.0. Normally this does not make the problem.
But if you have the following line in gradle.properties
android.uniquePackageNames = true
you will see the error
more than one library with package name 'android.support.graphics.drawable'"
If you should use the uniquePackageNames option, use androidx instead of support library 28.0.0.

In case someone like me stuck for hours and find out the you have to check the maven dependency "com.android.support:appcompat-v7:28.0.0". remove the "+" sign as gradle does not like it for unpredictable versions. so i had to check the maven repository and found that i was compiling with 29 and 29 does not exist. please check below link
[""][1]
apply plugin: 'com.android.application'

2)) Maven should be included.
allprojects {
repositories {
jcenter()
maven {

}

}
}
Wallah the problem is solved

Android Studio package in external jar cannot be resolved

I want to create an android app and I need an external SDK which I added to my project according to this answer: https://stackoverflow.com/a/30726911/4276486
In the picture below you can see that the packages in the external .jar cannot be resolved. However, when I am typing the IDE does autocomplete the package names but complains afterwards that the package cannot be resolved.
Any ideas how to fix this issue?
My gradle build file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "dhbw.naorobotapp"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile project(':java-naoqi-sdk-2.1.4.13-win32-vs2010')
}

Add this in your app gradle under dependencies, after you paste the .jar file under /libs
compile files('libs/<your jar filename>.jar')

Failed to resolve dependency while sync with gradle in Android studio 1.2

I just met this error while trying to sync gradle after add a new line in my app gradle file:
compile 'com.umeng.analytics:analytics:latest.integration'
The error is shown as below:
Error:A problem occurred configuring project ':app'.
Could not resolve all dependencies for configuration ':app:_debugCompile'.
Could not resolve com.umeng.analytics:analytics:latest.integration.
Required by:
PalmHeart:app:unspecified

Could not GET 'https://jcenter.bintray.com/com/umeng/analytics/analytics/maven-metadata.xml'.
Connection to http://127.0.0.1:8087 refused
And I think it might be something wrong with my http proxy, you can check this picture below:
And here is my gradle file:
apply plugin: 'com.android.application'

}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.android.support:support-v4:22.1.1'

compile project(':FloatingActionButton')
compile files('libs/andbase.jar')
compile files('libs/AndroidSwipeLayout-v1.1.8.jar')
compile files('libs/umeng-update-v2.6.0.1.jar')
}
I searched a lot in google but still can't figure out why, hopefully I could find the answer here.
Many thanks.

Changed build.gradle now can't install app delete faild internal error

I changed my gradles compileSdkVersion from 21 to 22 and forgot about it, a day later I plugged my phone in and wanted to debug my app, after trying to install once i get this message:
Installation failed since the device possibly has stale dexed jars that don't match the current version (dexopt error).
In order to proceed, you have to uninstall the existing application.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?
and after hitting the "ok" button i get this error:
DEVICE SHELL COMMAND: pm uninstall com.themeteam.roeikashi
DELETE_FAILED_INTERNAL_ERROR
this is my gradle file
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.themeteam.roeikashi"
minSdkVersion 15
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.android.support:support-v4:13.0.+'
compile 'com.parse.bolts:bolts-android:1.+'
compile fileTree(dir: 'libs', include: 'Parse-*.jar')
compile 'com.github.clans:fab:1.5.0'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.android.support:cardview-v7:22.1.1'
compile 'com.android.support:recyclerview-v7:22.1.1'
}
I could use some help on what to do, since I deleted all the files I could find that have a connection to my app and that doesn't seem to work.
I also changed back my compileSdkVersion to 21 which didn't work.
Thanks in advance!

The problem was in the gradle file, the compileSdkVersion was accidentally changed from 21 to 22, so I had to change it back, change the buildToolVersion and the target sdk version to the latest version.
the comments were way off, I ended up deleting all my phones cached data as my app does save some data on the phone itself and that didn't work.
It just occured to me that I should use the latest version and that fixed it.
here's the new gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.themeteam.roeikashi"
minSdkVersion 15

}
buildTypes {
release {
minifyEnabled false

}
}
}

compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.android.support:support-v4:13.0.+'
// compile 'com.parse.bolts:bolts-android:1.+'
