Android Studio报错 ：Failed to build project with Android studio

从eclipse里面导出项目要AS中突然爆这个错，解决方法：找到这个build.gradle文件

dependencies {
classpath 'com.android.tools.build:gradle:<span style="color:#ff0000;">1.5.0</span>'//这里需要修改工具的版本号
}

还有的问题就是你原来项目的SDK可能没有AS里面的版本高，需要修改一哈 
android {
<span style="color:#ff6666;">compileSdkVersion 19
buildToolsVersion '23.0.1'</span>

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')
