这是你的问题。

uses-sdk：minsdkversion 15不能与库[com.android.support:appcompat-v7:21.0.0-rc1]中声明的版本L不同

很奇怪的是，您的sdk文件夹中有AppCompat21的预览版。该版本随Lollipop预览（api-L）一起发布，并且具有minsdk=l。这就是问题的原因（因为您有MINSDKVersion15)

compile 'com.android.support:appcompat-v7:21.0.0'
compile 'com.android.support:appcompat-v7:21.0.2'
compile 'com.android.support:appcompat-v7:21.0.3'

compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.android.support:appcompat-v7:22.1.0'
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:appcompat-v7:22.2.1'

compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.android.support:appcompat-v7:23.0.1'
