Android NDK/JNI: loadLibrary failure with dependant shared libarires -

-

In my project, I need to load three different shared libraries, in which the third (main one) depends on the first two . The first two names for simplicity are A & A. Library A and B are large libraries which do not interact with JNI at all and only lock the existing libraries in Android.

I have set up this kind of Android radio in my third library. There is no such system by setting MK: 

  $ $ (CLEAR_VARS) LOCAL_PATH Include: $$ (MY_LOCAL_PATH) LOCAL_MODULE: = C LOCAL_SRC_FILES: = & lt; Source files & gt; LOCAL_C_INCLUDES: $ $ (MY_LOCAL_PATH) / libA / LOCAL_C_INCLUDES + = $ (MY_LOCAL_PATH) / libB / LOCAL_SHARED_LIBRARIES: = A LOCAL_SHARED_LIBRARIES + = B LOCAL_LDLIBS + = - $ $ (BUILD_SHARED_LIBRARY)

When I loaded this library via Java: 

  Fixed {System.loadLibrary ("C"); }

Too much success.

This system works on my device as well as all my beta testers get dissatisfied link entry in their stack trace: 

  java.lang. ExceptionInitializerError at & lt; Source & gt:: & lt; Line & gt; Reason: java.lang.UnconfirmedLink error at: Java.lang.Thread.run (Thread.Java: 856): The library can not be loaded: link_image [18 9 2]: 1909 The library required for 'libA.so' Could not load 'libA.so' (Load_library [1094]: java.lang.Runtime.loadLibrary (Runtime.java:370) at Java.Langu.System.Load Library (system.java / 355) on the source Library 'libA.so' is not found. & Lt; Line & gt; ...

is changing its code in: 

  static {System.loadLibrary ("A"); System.loadLibrary ("B"); System.loadLibrary ('C'); }

That tester seems to fix the problem.

With this problem, the examiner is running a Samsung Galaxy SIII (supported by my original code) AndroidM-V7A (similar to my device) with Android 4.1.2.

Given that the single "load c" works for everyone, but a tester, this tester has a problem in the device or "correct" way to clearly load these three libraries Does it for And why would it fail for only one device?

Yes, working clearly in A, B, and C The right way is Android. An alternative is to use , which is supported since NDK R9.

In any case, it is important to choose a special name for the libraries you use in the project so that any system is used by the library opportunity such as libcrypto.so in the Android device and libssl.so have / system / lib , but many apps require more advanced versions of these.

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
