'Source code does not match the bytecode'

Question

I have an app which I am compiling against API level 21:

and then debug it on a real device with API level 23:

The problem is when I try debugging through the Android OS's own classes, I get 'Source code does not match the bytecode'. Why is this happening? The test device the app is running on is API level 23, and the source file being debugged is level 23 as well.

I am really confused. Can anyone explain why I am seeing this message and how I can fix it?

Answer 1

There's an open issue for this in AOSP, where some users have given possible solutions: https://code.google.com/p/android/issues/detail?id=225199&sort=-id&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars

The potential solutions given there (as of the date of this post) are:

• Click Build->Clean
• Disable Instant Run, in Settings->Build, Execution, Deployment

Answer 2

Go to Project Settings > Artifacts. Select the artifact which has the problem. There is an option "Include in project build". This needs to be checked(enabled). For older versions of IntelliJ this option is "Make on build".

Answer 3

This can also happen in case you have enabled ProGuard. In buildTypes set minifyEnabled false, shrinkResources false, useProguard false

Answer 4

here is my solution

if you got more than one version libraries, it may help.

1. set a breakpoint on the lib source code
2. let the code run to the breakpoint

3. you will got these tips

   

4. click the arrow icon

5. you will got this

   

6. double click to select the correct lib (normally the highest version of the lib is correct)

   if have clicked the "disable" button by mistake, you can enable it in the debugger setting

if you do not have the tips in the step 3, maybe you can check whether you have checked the setting options.

I tried all the solution given here and none of them worked for me. In version 2019.1.3 I just clean & rebuild artifact and it worked; first do Build -> Build Artifacts... -> <select your artifact> -> Clean then click Build or Rebuild from same place.

Android Studio takes source version equal to Target Version in your application. Compilation performed with source version equal to above mentioned Compile Version. So, take care that in your project Compile Version == Target Version (adjust module's build.gradle file).
