Android Studio：Java库模块依赖性错误

Question

I've added a Java Library dependency module to the app module of my project. When I try to run the app I get this error:

...while parsing hai/shoplist/ItemBag.class 1 error; aborting Error:Execution failed for task ':app:preDexDebug'.com.android.ide.common.process.ProcessException:org.gradle.process.internal.ExecException: Process 'command 'C:\\ProgramFiles\\Java\\jdk1.8.0_05\\bin\\java.exe'' finished with non-zero exit value 1

I've tested the classes that I have in the module and I can even build it but the problem arises when I try to run the app.

Answer 1

Android doesn't support Java 8. Add to your library build.gradle:

sourceCompatibility = 1.7. 

It should solve your problem.

Answer 2

Due to Androids design, there is a limitation on how many methods your application may contain. You might have exceeded this amount. To solve this, enabled multidex support as explained here .

More information about it be found in the Android developer docs .
