Hi Shiliu, First of all thanks for support!
It was very interesting to hear that you have tested and got it to work. But unfortunately I cannot make it to work... I checked the XWalkCoreShell source code and could not find any major difference vs. my implementation. So I tried to run your code but it crashes when I test with 4 tabs. So what did I do? added: - mViewPager.setOffscreenPageLimit(4); - added two more mActionBar tabs tested with urls: - http://google.com - http://expressen.se - http://aftonbladet.se - http://jayway.com parts from log: below is repeated several times and finally a crash. 08-28 18:16:44.684 26416-26544/org.xwalk.core.xwview.shell E/qdmemalloc﹕ ion: Failed to map memory in the client: Out of memory 08-28 18:16:44.684 26416-26544/org.xwalk.core.xwview.shell E/qdgralloc﹕ Could not mmap handle 0x82735700, fd=413 (Out of memory) 08-28 18:16:44.684 26416-26544/org.xwalk.core.xwview.shell E/qdgralloc﹕ gralloc_register_buffer: gralloc_map failed 08-28 18:16:44.684 26416-26544/org.xwalk.core.xwview.shell W/GraphicBufferMapper﹕ registerBuffer(0x82735700) failed -12 (Out of memory) 08-28 18:16:44.684 26416-26544/org.xwalk.core.xwview.shell E/GraphicBuffer﹕ unflatten: registerBuffer failed: Out of memory (-12) 08-28 18:16:44.684 26416-26544/org.xwalk.core.xwview.shell W/Adreno-EGLSUB﹕ <SyncBackBuffer:3233>: handle base address is NULL 08-28 18:16:44.684 26416-26544/org.xwalk.core.xwview.shell W/Adreno-ES20﹕ <core_glFlush:52>: GL_OUT_OF_MEMORY 08-28 18:16:44.684 26416-26544/org.xwalk.core.xwview.shell W/Adreno-EGLSUB﹕ <SyncBackBuffer:3233>: handle base address is NULL 08-28 18:16:44.684 26416-26544/org.xwalk.core.xwview.shell W/Adreno-EGL﹕ <qeglDrvAPI_eglSwapBuffers:3692>: EGL_BAD_ALLOC ... 08-28 18:17:09.094 26416-26989/org.xwalk.core.xwview.shell W/Adreno-GSL﹕ <sharedmem_gpumem_alloc_id:1434>: sharedmem_gpumem_alloc: mmap failed errno 12 Out of memory 08-28 18:17:09.094 26416-26989/org.xwalk.core.xwview.shell E/Adreno-GSL﹕ <ioctl_kgsl_sharedmem_alloc:1535>: ioctl_kgsl_sharedmem_alloc: FATAL ERROR : (null) Br Stefan 2014-08-27 8:12 GMT+02:00 Wang, Shiliu <[email protected]>: > Hi, Stefan > > > > Actually, XWalkCoreShell is using ViewPager to contain two XWalkView > instances.
