android studio中的同步项目失败

Question

I'm totally new in android programming and by now just trying to run a "Hello World" program: But I couldn't! This is what I've done till now:

Previously I had android-studio-ide-171.4443003-windows installed on my laptop, and I installed all SDK Tools from SDK manager. But every time I wanted to sync a project it end up with this error:

ERROR: Could not find com.android.tools.build:gradle:3.5.0. Searched in the following locations: - file:/C:/Users/Pro/.android/manual-offline-m2/android-gradle-plugin-3.5.0-beta01/com/android/tools/build/gradle/3.5.0/gradle-3.5.0.pom - file:/C:/Users/Pro/.android/manual-offline-m2/android-gradle-plugin-3.5.0-beta01/com/android/tools/build/gradle/3.5.0/gradle-3.5.0.jar - file:/C:/Users/Pro/.android/manual-offline-m2/gmaven_stable/com/android/tools/build/gradle/3.5.0/gradle-3.5.0.pom - file:/C:/Users/Pro/.android/manual-offline-m2/gmaven_stable/com/android/tools/build/gradle/3.5.0/gradle-3.5.0.jar - https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.5.0/gradle-3.5.0.pom - https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.5.0/gradle-3.5.0.jar - https://jcenter.bintray.com/com/android/tools/build/gradle/3.5.0/gradle-3.5.0.pom - https://jcenter.bintray.com/com/android/tools/build/gradle/3.5.0/gradle-3.5.0.jar Required by: project: Open File

then I updated my android studio to android-studio-ide-191.5791312-windows32, and again it get that error. so I download android-gradle-plugin-3.5,0-beta01 and gmaven_stable from android developer site and as the site said. I extracted them and copy the content into [my home directory]\.android\manual-offline-m2, and then restart android studio, but the problem still exist!

Then I went to Settings > Build, Execution, Deployment > Gradle and checked the "Offline work" and specified the "Service directory path" as "[my home directory]/.android/manual-offline-m2/android-gradle-plugin-3.5.0-beta01" and again tried to sync the project, but sync got new error:

ERROR: No cached version of com.android.tools.build:gradle:3.5.0 available for offline mode.

now I'm totally confused and don't know what should I do to solve this problem. If anybody help me I will really appreciate that.

Answer 1

Open android studio go to your project -> build.gradle -> edit this code

dependencies {
    classpath 'com.android.tools.build:gradle:3.5.0'
}
}

Try lowering your build.gradle version to classpath 'com.android.tools.build:gradle:3.4.2'

I think your android studio does not support that kind of classpath version.
