将Android Studio Gradle Plugin从1.2.3升级到1.5.0后出现问题

Question

我正在尝试将我的Android项目在Android Studio中的Gradle插件从版本1.2.3升级到1.5.0（以便能够使用Vector Asset Studio）。问题是在将 classpath'com.android.tools.build：grad：1.2.3'更改为 classpath'com.android.tools.build:gradle:1.5.0'< /强>

我收到的错误就像PNG不正确，已损坏。只需[ProjectName：mergeDebugResources]。更改损坏的PNG无效......

有什么想法吗？谢谢！

我得到的错误：

Public Function establishConnection()

    Dim MysqlConn As MySqlConnection = New MySqlConnection()  
    Dim server_name = My.Settings.server_name
    Dim username = My.Settings.username
    Dim password = My.Settings.password
    Dim database = My.Settings.database

    MysqlConn.ConnectionString = "server=" & server_name & ";" _
    & "user id=" & username & ";" _
    & "password=" & password & ";" _
    & "database=" & database & ";"

    Return MysqlConn

End Function

添加以下行编译，但从16MB的APK增长到45MB
