提示的错误

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.> com.android.build.api.transform.TransformException: java.lang.RuntimeException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_79\bin\java.exe'' finished with non-zero exit value 1

解决办法：

File-->ProjectStructure--->把Build Tools Version 24.0.0改成23点几的。
