報錯：Error running app: This version of Android Studio is incompatible with the Gradle Plugin used. Try disabling Instant Run (or updating either the IDE or the Gradle plugin to the latest version)
解決辦法：
step1:
禁用Instant Run，在Settings/Preferneces > Build, Execution, Deployment option > Instant Run 中，取消所有的選中項
step2:
更新gradle services 的url：在project目錄下的 gradle>wrapper>gradle-wrapper.properties中將
distributionUrl=https://services.gradle.org/distributions/gradle-2.10-all.zip
更新爲：
distributionUrl=https://services.gradle.org/distributions/gradle-2.11-all.zip
step3:
刪除project下的build文件夾
step4:
clean項目，重新編譯跑程序
