when I run my android app i have 3 errors

1)

Error:Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add 
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.

2)

Error:1 error; aborting
:app:transformClassesWithDexForDebug FAILED

3)

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 (x86)\Java\jdk1.7.0_55\bin\java.exe'' finished with non-zero exit value 1

    *"This is caused by library dependencies that have been compiled using Java 8 or above."*. Which dependency is compiled using Java 8? Including your gradle.build might enable someone to help you. There's some more info on these pages http://stackoverflow.com/questions/37020413/android-dex-cannot-parse-version-52-byte-code http://stackoverflow.com/a/36975041/6178459 Suggested solutions are either to compile the entire project as java 8 or downgrade the dependency.
