我有一个在 Eclipse 中创建的 Android 项目,导出为 Gradle 构建文件,然后在 Android Studio 中打开。(是的,在 AS 中创建一个干净的项目会容易得多,但我需要支持当前的项目结构。)
否则事情现在大部分都在工作,但仍有一些问题需要解决。在每个 Activity 类中,AS 都会显示此错误:Class requires API level 1 (current min is -1): Activity
Alt+Enter 提供了一个@TargetApi
注释来解决这个问题......但是为什么我必须这样做,当在 中时AndroidManifest.xml
,我们有:
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="18" />
AndroidManifest.xml
位于项目根目录(Eclipse 默认?)。看起来 Android Studio 没有正确读取其中的设置。该项目仍然可以正常编译。
知道如何摆脱错误吗?
Eclipse 生成的build.gradle
看起来像这样:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.5.+'
}
}
apply plugin: 'android'
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}
android {
compileSdkVersion 18
buildToolsVersion "18.1.0"
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
}
