使用Android Studio可能会遇到的问题

Error:Execution failed for task ':app:processDebugManifest'. > Manifest merger failed : uses-sdk:minSdkVersion 8 cannot be smaller than version L declared in library com.android.support:support-v4:21.0.0-rc1

解决方式： 1、Change compile 'com.android.support:support-v4:+' to compile 'com.android.support:support-v4:20.+' in build.gradle. This will prevent gradle from using v4:21.0.0 that requires version L. 
2、Remove/Comment 21.0.0-rc1 in your file /extras/android/m2repository/com/android/support-v4/maven-metadata.xml

Failed to import Gradle project: Could not fetch model of type 'IdeaProject' using Gradle distribution 'http://services.gradle.org/distributions/gradle-1.6-bin.zip'.

解决方法：先从网页上将其下载下来，然后将其解压到任何位置，在环境变量path下配置路径（到gradle的bin目录），可通过cmd命令 gradle -v验证是否成功。

"Could not find any version that matches com.android.support:support-v4:13.0.+"
