  61. Tips for migration • organise your project layout • organise

    your module layout 75 android { sourceSets { main { manifest.srcFile 'AndroidManifest.xml' java.srcDirs = ['src'] res.srcDirs = ['res'] assets.srcDirs = ['assets'] } } }
  62. Tips for migration • replace ‘*@@aar’ with correct library module

    • use local module • create build.gradle under library module • add library project in settings.gradle • modify build.gradle under app (library) module • use remote module • http://gradleplease.appspot.com/ • check remote dependencies 76
  63. Tips for migration • replace ‘*@@aar’ with correct library module

    • use local module • create build.gradle under library module • add library project in settings.gradle • modify build.gradle under app (library) module • use remote module • http://gradleplease.appspot.com/ • check remote dependencies 77
  64. Tips for migration • replace ‘*@@aar’ with correct library module

    • use local module • create build.gradle under library module • add library project in settings.gradle • modify build.gradle under app (library) module • use remote module • http://gradleplease.appspot.com/ • check remote dependencies 78
  65. Tips for migration • replace ‘*@@aar’ with correct library module

    • use local module • create build.gradle under library module • add library project in settings.gradle • modify build.gradle under app (library) module • use remote module • http://gradleplease.appspot.com/ • check remote dependencies 79
  66. Tips for migration • import project to a new directory,

    see if everything is all right • modify module settings, see what changed inside the build.gradle • use the imported project as reference, create the build files from scratch for your original project 80
  67. Tips for migration • import project to a new directory,

    see if everything is all right • modify module settings, see what changed inside the build.gradle • use the imported project as reference, create the build files from scratch for your original project 81
  68. Tips for migration • import project to a new directory,

    see if everything is all right • modify module settings, see what changed inside the build.gradle • use the imported project as reference, create the build files from scratch for your original project 82
  69. Tips for migration • import project to a new directory,

    see if everything is all right • modify module settings, see what changed inside the build.gradle • use the imported project as reference, create the build files from scratch for your original project 83
  70. Shared library • define path_to_share_library in ~/.gradle/ gradle.properties or <project_rootdir>/

    gradle.properties • project(‘:xxx’).projectDir = new File(path_to_share_library) • dependencies in shared library should be defined in project’s settings.gradle also. 84
