我有一个INTELIJ（V12）Android的成功导入到AndroidStudio（V0.4.0）项目。它完美，如果我不改变任何东西的清单。当我想改变发射活动并运行，它与下面的错误输出：

I have an INTELIJ(v12) android project successfully imported to AndroidStudio(v0.4.0). It works perfectly if I don't change anything in manifest. When I want to change the launcher activity and run, it outputs with the following error:

Launching application: com.trackingeng/LandingActivity.
DEVICE SHELL COMMAND: am start -D -n "com.trackingeng/LandingActivity"  
    -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Starting: Intent { act=android.intent.action.MAIN  
    cat=[android.intent.category.LAUNCHER] cmp=com.trackingeng/LandingActivity }
Error type 3
Error: Activity class {com.trackingeng/LandingActivity} does not exist.

当我点击同步工程与摇篮文件它输出：

Project Sync
The project 'TrackingEng' is not a Gradle-based project
