Text relocations and crash in android 6.0 #76

wildfatduck · 2015-09-26T04:39:28Z

When decoder library is loaded we have this warning:

W/linker: libaacdecoder.so has text relocations. This is wasting memory and prevents security hardening. Please fix.

But, if we set build target to API 23 and run this app on android 6.0 (emulator or device, doesnt matter) this causes exception and app force close.

gc435 · 2015-10-19T22:19:35Z

I can confirm that setting the target SDK version to 23 causes my app to crash when playing AACPlayer. It does not crash when the target SDK version is 22. This was tested on the Marshmallow armeabi-v7a emulator.

The issue is that the native components have text relations, and Marshmallow won't load them. Earlier versions of Android would load native components even if they had text relocations.

I believe the solution is to recompile with the latest version of the NDK, and make sure there are no text relocations. More:

I have not rebuilt the aacdecoder components yet myself, since I will target SDK version 22 for the time being.

wildfatduck · 2015-10-20T14:49:50Z

Recompile with the latest version of the NDK is not helped

Fixed here.

@tarigo

Hmm.. when I've used *.so files that I've compiled from your code I'm getting this:

Any ideas?

tarigo · 2015-12-14T17:12:40Z

@radzio
Apparently segfault, memory SEGV_MAPERR - address not mapped to object. Without exact steps to reproduce I can guess only.

radzio · 2015-12-15T09:33:13Z

@tarigo it was my fault. I didn't update java code. After it everything has started working like a charm! THX!

089apps · 2016-01-14T14:06:50Z

could anyone provide the compiled files
armeabi / libaacdecoder.so
armeabi-v7a / libaacdecoder.so

thx so much

lucViana · 2016-01-14T15:01:31Z

@089apps Here it is :)

android.zip

Unfortunately I got the following exception: INFO] Decoder: start() starting native decoder - OpenCORE-MP3 [INFO] art: art/runtime/thread.cc:1336] No pending exception expected: java.lang.NoSuchMethodError: no non-static method "Lcom/spoledge/aacdecoder/Decoder$Info;.next()Lcom/spoledge/aacdecoder/BufferReader$Buffer;" [INFO] art: art/runtime/thread.cc:1336] at int com.spoledge.aacdecoder.Decoder.nativeStart(int, com.spoledge.aacdecoder.BufferReader, com.spoledge.aacdecoder.Decoder$Info) (Decoder.java:-2) Alternatively I found this thread: vbartacek/aacdecoder-android#76 With a link to a android.zip with new compiled accdecoder libs fixing text relocations issues, preventing the lib to run on Android 6.0 Marshmellow. I updated the libs in the 1.7.1 version of Trevor's module. Everything works now!

Informatheus · 2016-03-23T18:41:45Z

@tarigo how do I use your fork?
sorry im noob yet with github but I need to use aacdecoder on android M.
Can somebody please help me?

Informatheus · 2016-04-12T14:41:43Z

@karaoak how do i use your fork?

Informatheus · 2016-04-13T14:07:34Z

I'm already using the new lib and it works on Android M.
I hosted the files, if someone want:

lucViana · 2016-04-13T14:09:04Z

@Informatheus where did u find it the new lib?

Informatheus · 2016-04-13T14:11:13Z

@lucViana are the same that you posted. I only structured according to project folders and zipped with an instructions file.
Very thanks.

lucViana · 2016-04-13T14:13:33Z

@Informatheus ooh great :)

Informatheus · 2016-04-13T14:26:34Z

@lucViana you have no idea how much u helped me and other developers.
How did you get the files? And from where?

ravenet · 2016-04-28T03:56:43Z

Hi Informatheus,

I see this lib is nice and could we improve further because there are some other issues as well in this lib.

the network packets possible to drop during decoding time so now it is show the log that it is waiting, but there is not event or something to trigger to top level to inform users.
sometimes it is stopped even there is stream available from the server. So if we could retry a few times before give up that would be better.
improve the quality of audio

citerio · 2016-07-20T01:52:42Z

Awesome, Informatheus , I am just using the new lib and testing a shoutcast audio/aacp on Eclipse Android 6.0 Emulator and it is working so f...ing awesome, thanks.

citerio · 2016-07-20T03:03:54Z

Same thing on Android Studio 2, working great on Android 6.0 emulator.

bkoruznjak · 2017-01-22T01:00:58Z

Just tested it on Nexus 5x with Nougat works like a charm after replacing the .jar and .so files with the ones from the zip provided on the link above. Thank you so very much :)

"Informatheus" that's work!

@AppWerft You can download the requsted so files from maximxt@fd8d24b

I have tested its working fine but this maximxt#1 issue occurs rarely.

AppWerft · 2019-07-30T14:08:13Z

Currently I'm using a libs package from a phonegap project:
https://github.com/AppWerft/HoerDat/tree/master/modules/android/com.woohoo.androidaudiostreamer/3.0.0/libs

mylselgan · 2019-07-30T14:15:47Z

@AppWerft have you recreated your app from scratch using Phonegap or can we just use these .so files in our android app for 64 bit support?
what about signal 11 (SIGSEGV), code 1 (SEGV_MAPERR) crash issues?

AppWerft · 2019-07-30T14:31:09Z

I found this libs in an phonegap project and I'm using it in my Titanium project. I never seen this crash.
