Android Studio Settings

在AS中阅读Settings源代码，主要是配置和导入jar包

Gradle Error

  • Android Studio import project
  • Error “Minimum supported Gradle version is 5.1.1. Current version is 4.4.1” after update android studio

    • gradle/wrapper/gradle-wrapper.properties

      distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

    • default: gradle-4.8-bin.zip

  • Andriod Gradle Sync failed

    • build.gradle

      // Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        mavenCentral()
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.1'
    }
}

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

    • 默认只有jcenter()，加上另外两个；

  • 安装一下SDK 28；
  • 导入系统的jar包：
    • out/soong/.intermediates/frameworks/base/packages/SettingsLib/SettingsLib/android_common/javac/Settings/SettingsLib.jar
    • 将上面的文件拷贝到Android Studio项目的：app/libs
    • [Project Structure] -> [Dependencies] -> [Modules] -> [app] -> [+] -> [jar Dependency] -> [libs]
    • 将AndroidX相关的jar包拷贝出来： 
      #!/bin/bash

outdir=jars
mkdir ${outdir}

jars=(`find * -iname androidx.*.jar`)
i=0

for jar in "${jars[@]}"
do
        fileName=`basename $jar`
        echo "${i} copy ${jar} to ${outdir}/${i}-${fileName}"

        cp ${jar} ${outdir}/${i}-${fileName}

        ((i=i+1))
done

cp out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar ${outdir}
cp out/soong/.intermediates/frameworks/base/packages/SettingsLib/SettingsLib/android_common/combined/SettingsLib.jar ${outdir}/1-SettingsLib.jar
cp out/soong/.intermediates/frameworks/base/packages/SettingsLib/SettingsLib/android_common/javac/SettingsLib.jar ${outdir}/2-SettingsLib.jar
    • 更新libs下的jar包后，要用[Project Structure]同步一下；

Android Studio继承关系查看

  • [Navigate] -> [Type Hierarchy]
  • ctrl+h

跟代码快捷键

  • ctrl + 鼠标左键
  • alt + 左右方向键
