Error writing mapping file: No such file or directory #185

222xiaohuan · 2016-10-25T02:49:08Z

Hi there,

I used the tool according to the guide, everything went fine with the installing process. but when I use redex command to compress the apk, I encountered this error: " Error writing mapping file: No such file or directory."
here are my system info and error screenshot.

Can anybody help?

Thanks a lot!

Can anybody help? any progress @samyakjain @eagertofly @Szmiglo ?

I guess this is jus one warning and you can still gent the output apk file. @222xiaohuan

LeerGo · 2016-10-27T07:32:44Z

The same with me, but I can still get a new apk file.
but I fails to install with Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES], look it at readme.md
@eagertofly @222xiaohuan

eagertofly · 2016-10-27T07:41:15Z

you need to sign the apk with your keystore @xoder-me

LeerGo · 2016-10-27T07:43:16Z

@eagertofly yes， i have readed the offical document... i just try it. but thx!

samyakjain · 2016-10-27T15:45:41Z

Yes. It is still generating output file so just ignoring this as a warning
and going ahead.

Yes, I can get the package, but before doing the compress, the package size is 18.6M, after doing that, the size is 18.3, so I am not sure if the compress really works. and by the way how the package size changed of yours? @eagertofly @samyakjain @xoder-me

samyakjain · 2016-10-28T09:41:41Z

Not much of significant change in package size. That's why i am also in
doubt if redex is properly working or not. Difference of only .1 Mb (from
9.7 to 9.6)

Redex usually doesn't decrease the APK size much; it'll usually make the dexes (bytecode) noticeably smaller, but that compresses well anyways so it doesn't make a big difference in APK size. You can check the dex size using aapt.

{
    "redex": {
        "passes": [
            "ReBindRefsPass",
            "BridgePass",
            "SynthPass",
            "FinalInlinePass",
            "DelSuperPass",
            "SingleImplPass",
            "SimpleInlinePass",
            "StaticReloPass",
            "RemoveEmptyClassesPass",
            "ShortenSrcStringsPass"
        ]
    },
    "ShortenSrcStringsPass": {
        "filename_mappings": "filename_mappings.txt"
    }
}

write redex.conf file.

and

redex ~~ -c redex.conf

filename_mappings default value : /tmp/filename_mappings.txt

/tmp/filename_mappings.txt permission denied

mJackSparrow · 2016-12-14T12:41:05Z

I have the same problem.:(

yiwowang · 2016-12-15T03:21:01Z

I have the same problem.:(

And the command line not working:
ANDROID_SDK=/Users/yiwowang/Library/Android/sdk redex app-debug.apk -o output12345.apk -c config/default.config

asamaru7 · 2016-12-15T08:51:41Z

@yiwowang
Did you create a "config / default.config" file?

vipinemvigo · 2016-12-27T13:52:50Z

I have appended the code
"
"ShortenSrcStringsPass": {
"filename_mappings": "filename_mappings.txt"
}
"
in the 'default.config' file, then tried again with a signed apk, the output apk is generated successfully with the same error message on the terminal "Error writing mapping file: No such file or directory ", but I can't install the apk file.Only change in the apk size is .1 Mb

asamaru7 · 2016-12-28T01:58:25Z

I write redex.conf.

{
    "redex": {
        "passes": [
            "ReBindRefsPass",
            "BridgePass",
            "SynthPass",
            "FinalInlinePass",
            "DelSuperPass",
            "SingleImplPass",
            "SimpleInlinePass",
            "StaticReloPass",
            "RemoveEmptyClassesPass",
            "ShortenSrcStringsPass"
        ]
    },
    "ShortenSrcStringsPass": {
        "filename_mappings": "filename_mappings.txt"
    }
}

and run redex

$ redex ~~~ -c redex.conf

vipinemvigo · 2016-12-28T05:37:55Z

In 'redex ~~~ -c redex.conf' ' ~~~' means path of the config file ?

asamaru7 · 2016-12-28T06:34:24Z

no. ~~~ is other arguments.

example

$ redex xx.apk -o r.apk -sign --keystore ~~ --proguard-map ~~ --proguard-config ~~  -c /path/redex.conf

vipinemvigo · 2016-12-28T08:10:51Z

ok, thanks
I tried it(without proguard) but the same result again, I have attached a screenshot of the terminal.

asamaru7 · 2016-12-28T08:58:19Z

Did you put the following in default.config?

{
    "redex": {
        "passes": [
            "ReBindRefsPass",
            "BridgePass",
            "SynthPass",
            "FinalInlinePass",
            "DelSuperPass",
            "SingleImplPass",
            "SimpleInlinePass",
            "StaticReloPass",
            "RemoveEmptyClassesPass",
            "ShortenSrcStringsPass"
        ]
    },
    "ShortenSrcStringsPass": {
        "filename_mappings": "filename_mappings.txt"
    }
}

And did you reinstall redex to the latest version?

opt/shorten-srcstrings/Shorten.cpp

...
  // generate mapping
  FILE* fd = fopen(map_path, "w");
  if (fd == nullptr) {
    perror("Error writing mapping file");
    return;
  }
...

If the error persists Try removing ShortenSrcStringsPass as it seems to be related to "Shorten".

{
    "redex": {
        "passes": [
            "ReBindRefsPass",
            "BridgePass",
            "SynthPass",
            "FinalInlinePass",
            "DelSuperPass",
            "SingleImplPass",
            "SimpleInlinePass",
            "StaticReloPass",
            "RemoveEmptyClassesPass"
        ]
    }
}

If not, I do not know. sorry.

vipinemvigo · 2016-12-28T09:46:42Z

Great, Thanks @asamaru7 for the solution, The third method is work for me, Now there is no error related to the mapping file.Apk is generated without any error message, but unable to install the apk file .

samyakjain · 2017-01-28T17:50:00Z

Updated to latest, still getting the same warning. But I have also noticed that my after redux my apk's download size reduced by .9mb . So i am assuming redux is working fine.

bertmaher · 2017-01-28T19:09:47Z

This warning should be gone in master. The next release version will fix it for good On Jan 28, 2017, at 9:50 AM, Samyak <notifications@github.com<mailto:notifications@github.com>> wrote: Updated to latest, still getting the same warning.

It sounds like this was fixed back in January. Closing. Please re-open or create a new issue if you see this error again.
