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?
There's an open issue for this in Google's IssueTracker.
The potential solutions given in the issue (as of the date of this post) are:
Click Build -> Clean
Disable Instant Run, in Settings -> Build, Execution, Deployment
Here is my solution:
If you got more than one library version, this may help.
set a breakpoint on the lib source code
let the code run to the breakpoint
you will got these tips
click the arrow icon
you will get this
double click to select the correct lib (normally the highest version of the lib is correct)
I 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
You should use an Android emulator with the same api level as the compileSdkVersion.
In your case you should use Android emulator with api level 21.
If you use Gradle, it is probably a problem with Gradle caches. (Reference). Alas, even if you run
gradle --refresh-dependencies
, it is not refreshing really all dependencies. Some rubbish remains. (Reference).
So, the most sure (but drastic and long) variant is to clear all inside from the [user]/.gradle/caches. Or to find your problem project there and clear only its caches.
My app is compiled on API LEVEL 29, but debugging on real device on API LEVEL 28.I got the warning source code does not match the bytecode in AndroidStudio.I fixed it thought these steps:
Go to Preferences>Instant Run: uncheck the instant run
Go to Build>Clean Build
Re-RUN the app
Now, the debug runs normal.
These are the steps that worked for me (For both Mac and Windows):
Click on "File"
Click on "Invalidate Caches / Restart ..."
Choose: "Invalidate and Restart"
Note: It will take less than a minute for small projects, but since my project was big (approximately one million lines of code), it took 20 minutes.
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.
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".
Probably this error message can have more than one cause, my case was not like the one from the OP, in my case this was due to a 3rd party library that required additional libraries.
For example: you manually add X.jar to your LIB, but this X.jar requires Z.jar to work.
It took me sometime to figure out, the message was not helping at all. I had to debug the app until I reached the crashing class, and in that class make sure that all imports were satisfied.
(Particualry: I added MercadoLibre-0.3.4.jar, which required commons-httpclient.jar)
Hope this helps!
This can also happen in case you have enabled ProGuard. In buildTypes set minifyEnabled false, shrinkResources false, useProguard false
I tried the solutions given here while working on an application that used Bluetooth Low Energy(BLE). I tried,
Clean Build
Disabled Instant Run
Invalidate Caches / Restart
all of these failed.
What I did was debug the points where I thought I was getting the warning, I still got the warning but the application was working fine. You can disregard the warning.
You can created AVD, select API Level equal your tagetApi andr compileApi, it works for me.
So I created an account just so I could help fix this problem that is plaguing a lot of people and where the fixes above aren't working.
If you get this error and nothing here helps. Try clicking the "Resume program play button" until the program finishes past the error. Then click in the console tab next to debug and read the red text.
I was getting that source code error even though my issue was trying to insert a value into a null Array.
Step 1 Click the resume button
Step 2 Click the console tab and read the red text
here is cause of why I got this error "source code does not match bytecode". My cause doesn't have anything to do with any API, compiler version..... It is caused by when inflate a layout view into a root view while I mistakenly initiate the inflator in else where (a chuck of "result handler" code that put on top of onCreate function of android app code). Somehow the debugger doesn't give me right hint of this (ex, inflator is not initialized or has instance) when breakpoint is set and stop here.
This happened to me when accidentally I have added the same library multiple times.
implementation 'androidx.appcompat:appcompat:1.1.0'
The above library was added multiple times.
If clean, rebuild, invalidate cache and restart etc. techniques are not working, then try deleting the previous APK and reinstalling the new APK.
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).
I had the same issue and found a solution. If you have a line flagged in red, it will give you this error, but if you un-flag all of the lines it will work normally.
by flagged I mean when you click on the left side where the line numbers are and it highlights the line.
If that is not clear here are pictures.
go from:
flagged line
to:
not flagged line

Very new to programming and Android Studio.
Getting a problem when trying to run my program, can anybody help?
FAILURE: Build failed with an exception.
What went wrong:
Could not add entry ':app:sourceSets' to cache taskArtifacts.bin (/Users/marcelgarvey/AndroidStudioProjects/SimpleTipCalculator/.gradle/2.4/taskArtifacts/taskArtifacts.bin).
Unable to store task input properties. Property 'config' with value 'com.android.build.gradle.AppExtension_Decorated#a8d1ae3' cannot be serialized.
I know nothing (well I do), but I'm kinda new to Android Studio as well.
Seeing as I just sumpled into the same problem, and google pointed here, I thought I'd add my observations/fix.
What created the problem:
I accidentally double-clicked sourceSets under the Gradle pane. (:app/Tasks/android/sourceSets)
And whenever building the project the same error came up.
What happened/fixed it:
It had changed the build profile (right next to the Run and Debug buttons), to something about that sourceSets.
Changing the build profile back fixed the problem.
Just remove the file: taskArtifacts.bin localised in the .gradle folder, and put a space on gradle file and sync.
I am also having this issue. I think this might be a bug in Gradle. Here is some information I was able to find:
"This exception indicates that Gradle cannot persist the Task execution state when the Task successfully completes, because some element in the Task state is not Serializable." (Source)
It appears that sourceSetsTask has a property called "config" of type AndroidConfig that is not serializable, and that's what is causing the error. (Source)
I write a android app in Eclipse and use run command on my cellphone.
It's run success on my cellphone.
But I use [Android Tools -> Export Signed Application Package...] to export my app.
Then use [adb install] to install apk on my cellphone and run.
And I got the error message:
07-22 11:20:43.537: E/AndroidRuntime(20216): Caused by: java.lang.ClassNotFoundException: com.mytest.MyActivity in loader dalvik.system.PathClassLoader[/data/app/com.mytest-1.apk]
In [Java Build Path -> Order and Export], I have been selected all.
In AndroidManifest.xml, the application attribute doesn't have android:name.
I don't know how to solve this problem.
I'm success use Eclipse run on my cellphone, why run error when I export the app?
please help me, thanks!!
I had same issue, after 2 hours of research I managed to fix this problem by deleting "bin" and "gen" folders and rebuilding project.
There seems to multiple reasons for this happening from what I have researched. Do you have a lib folder? if so change it to "libs".
Do you have proguard enabled? If so that may cause the problem.
Also try unchecking the "Android #.#.#" and "Android Dependencies" in your Build Path, Order and Export.
Check out this thread which has a bunch of other possible solutions, a lot of them deal with setting the proper ActivityName in the manifest file.
java.lang.ClassNotFoundException on working app
If those solutions still don't solve the problem try these threads.
Android: Unable to instantiate activity / ClassNotFoundException
ClassNotFoundException Android
What I had to do is just re-do the building/exporting process with no modification to the code whatsoever. It worked for me, which I did was to export it two times.
On my first export, the build APK has lower file size and the second export (with no any modification to the code/configuration) produced a slightly larger file size (about 200KB diff).
This bug in building is really costly, kills you in front of your manager, and should be really fixed by Android/Eclipse team. Kind of sucks
I tried everything and nothing helps me :(
At first I got:
INSTALL_FAILED_DEXOPT error when trying to install application
Please check logcat output for more details.
Launch canceled!
And then the first error changed to
Installation error: INSTALL_FAILED_UID_CHANGED
I am running the app on Genymotion, so I don't have root and can't delete /data. I restarted eclipse and Genymotion (and tried different emulators in vein). I cleaned my project many times. I uninstalled every app from Settings/Apps, and cleared the app from Storage/misc. I can't factory reset Genemotion. The installation fails on my device (Galaxy 4). I also changed my package name, with no help.
My logcat shows:
cutils-trace(1311): Error opening trace file: No such file or directory (2)
memtrack(1311): Couldn't load memtrack module (No such file or directory)
android.os.Debug(1311): failed to load memtrack module: -2
I tried to revert the code to a known working GIT version, with no help - still installation error: INSTALL_FAILED_DEXOPT. Also - I can't open ab eclipse emulator.
What can I do?
I don't know how, but somehow eclipse was having problem with my package. When I turned 'x_y_z' to 'test', it worked. So weird that it happened out of the blue (I had 'x_y_z' for more than 7 months...).
This usually happens during development when some files don't get removed while installing the new apk over the existing one. If you check the LogCat, you would be able to find exactly which resource was left behind. This is mostly caused by using two different PCs to test on the same device, or also sometimes using a single PC and a BROKEN_PIPE_ERROR while trying to install over an existing version.
Since, some files corresponding to your package stay behind, an application with the same package cannot be installed, until and unless those files are removed forcefully (for which you would need root access).
Or, you could factory reset the device.
If you can't factory reset or don't have root access, you would need to change the package name of the application. Because then, it tricks the OS to believe that it is a separate application, which is why it worked in your case.
