问题

Hi, I downloaded android studio and installed it downloaded API 30.0.1

but when I press Ctrl+Q to show inline docs, android studio try to fetch it from the network online

I need it to work offline, I can not find the old option in the SDK manager

And when I try to navigate to any class or method in android API navigate to source Ctrl + L-mouse-button

android studio show me

and when I press on download option in the top right corner

it shows me

And This is My SDK Manager

The Project

And build.gradle Module

apply plugin: 'com.android.application'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.1"

    defaultConfig {
        applicationId "com.albanna.databaseworks"
        minSdkVersion 19
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'androidx.recyclerview:recyclerview:1.1.0'
    implementation 'androidx.cardview:cardview:1.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

}

build.gradle Project

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.0.0"

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

allprojects {
    repositories {
        google()
        jcenter()
    }
}

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

My SDK Folder

My Laptop Configurations

Processor   Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz, 2592 Mhz, 6 Core(s), 12 Logical Processor(s)

BIOS Mode   UEFI

Installed Physical Memory (RAM) 16.0 GB, dual-channel 2666 MHz

SSD NVME M2 3200/2500 read/write MB/S

So I need it to work like IntelliJ IDE or Rider, when I press Ctrl+Q on any method, it should show the docs and I can navigate to the source Offline

Thanks.

I Found The Solution

This problem because Google does not provide the source code of API 30 yet, so I just go back to API 29, and everything work

from File → Project Structure → Modules

then change

• Compile Sdk Version to 29
• Build Tools Version 29.0.3

Also notice: you must have Source For Android 29 or any version you have, selected in SDK Platforms

I notice this problem from this thread on readit

And this says that Google will only release the source with the system, not with the API.

So I just go back to API 29
