I'd recommend upgrading to the latest version of Android Studio, which is 3.3

(moved thread to development forum)

I once has 3.3 , but I am unable to solve the dependencies problem. I get error on the following part . I Google and found a lot of people said they have this problem , but no of the solution is work for me

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:design:28.0.0'
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'
}

So now that you have android studio 3.3 installed, what does the error say? Can you post the error?

Also this is what build.gradle looks like in a newly created project in AS 3.3:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.gt.helloworld"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    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'
}

I also noticed if I common the following I did not have Gradle sync problem
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:design:28.0.0'
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'

if I am unable to get those jar online , can I download and put in where? how my Gradle build need to change?

 

[GameTheory]

Once you open your project in AS allow it to finish loading. Then on the AS tool bar click on the button labeled "Sync Project with Gradle Files". This usually solves the dependency issues. If it doesn't let us know.

I've noticed that windows users are having some issues with AS that linux and mac users don't seem to be having.

Thanks for the reply!
but the dependency issues happen when "Sync Project with Gradle Files".

No, if android studio(AS) is not installing correctly then you need to completely remove it from windows and reinstall it.

Here is a guide to completely remove it.
https://stackoverflow.com/a/39953746

And here is another thread where a user was having issues with his AS installation and simply removing it and then reinstalling it fixed it.
https://androidforums.com/threads/c...in-android-studio.1296456/page-2#post-7857984

We can spend a bunch of time trouble shooting, but if your installation of AS is botched, then nothing will work.

Thanks for the reply ! actually I try to remove before , I do all other steps, but I did not do the step 3 before . I will try it again !

*****************************************
Step 1: Run the Android Studio uninstaller

The first step is to run the uninstaller. Open the Control Panel and under Programs, select Uninstall a Program. After that, click on "Android Studio" and press Uninstall. If you have multiple versions, uninstall them as well.

Step 2: Remove the Android Studio files

To delete any remains of Android Studio setting files, in File Explorer, go to your user folder (%USERPROFILE%), and delete .android, .AndroidStudio and any analogous directories with versions on the end, i.e. .AndroidStudio1.2, as well as .gradle and .m2 if they exist.

Then go to %APPDATA% and delete the JetBrains directory.

Finally, go to C:\Program Files and delete the Android directory.

Step 3: Remove SDK

To delete any remains of the SDK, go to %LOCALAPPDATA% and delete the Android directory.

Step 4: Delete Android Studio projects

 

[Learn Android]

Then go to %APPDATA% and delete the JetBrains directory.

%APPDATA% in没有 Win7 is point to
C:\Users\mylogin account\AppData\Roaming
could not find JetBrains

The best tutorial to follow would be in the following link which includes both a written and video tutorial for the supported operating systems.

I don't use Windows so I cannot assist with any windows troubleshooting.
