Android Studio

Android Studio/NDK

Top / Android Studio / NDK

メモ

• As of Jan 2015 the NDK support for Android Studio is still unusable. A cryptic message says: "Alternative will be provided in the future."
  • Version 0.7+: They suggested to still use ndk-build / ant
  • Version 0.8+: They've introduced a minimal NDK support
  • Version 1.0.0: It looked like NDK support was going to be official
  • Version 1.0.2: It now looks like NDK support is deprecated.

ADT時代のプロジェクトをインポート

• Error:(13, 0) NDK integration is deprecated in the current plugin.
• Consider trying the new experimental plugin
  • http://tools.android.com/tech-docs/new-build-system/gradle-experimental
• Set "android.useDeprecatedNdk=true" in gradle.properties to continue using the current NDK integration

方法1

• Android Studio/プロジェクト/gradle.propertiesで
  • android.useDeprecatedNdk=true
• Android Studio/プロジェクト/app/build.gradleで
  • sourceSetsとかを設定

    android {
        sourceSets {
            main {
                jni.srcDirs = []
                jniLibs.srcDirs = ['src/main/libs']
            }
        }

• jniLibs.srcDirs = ['src/main/libs', 'src/main/jniLibs'] // Here!

• もしくはsrc/main/libs以下のファイルをAndroid Studio/プロジェクト/app/src/main/jniLibsにコピーする
