问题 I'm having a set or Gradle modules that uses the core module based on c++ code: Core (C++ with JNI glue, aar with libxyz-jni.so ) Tests (Android instrumentation tests) App (regular Android app) Core module includes native 32 bit libxyz-jni.so compiled for armeabi-v7a and x86 and is compiled to aar . It does not have arm64 libraries. App module depends on Core and is working on arm64 hardware device without any issues (is able to load libxyz-jni.so ) Tests depends on Core and fails to load

问题 I'm trying to set up OpenSL AudioPlayer to use memory I've allocated to playback a wav file. I want to do this so I can have multiple AudioPlayers that share the same data and conserve memory. I've tried to give openSL the entire file and tell it that it is a WAVE with format_mime SLDataLocator_Address loc_fd = {SL_DATALOCATOR_ADDRESS, data, size}; SLDataFormat_MIME format_mime = { SL_DATAFORMAT_MIME, (SLchar*)"audio/x-wav",SL_CONTAINERTYPE_WAV}; SLDataSource audioSrc = { &loc_fd, &format

问题 When i tried to put this command while building pjsip for android, TARGET_ABI=armeabi-v7a ./configure-android --use-ndk-cflags This error occured, compiler not found, please check environment settings (TARGET_ABI, etc) can somebody give me an explanation.pls 回答1: I'm sure you've moved on past this by now, but for anyone else who finds this thread: Just set the NDK_TOOLCHAIN_VERSION environment variable to 4.9 This can be done either by doing an export prior to the configure call: export NDK

问题 I have created a static library (with extension .a) for iOS with Xcode. These were my build-settings: Architectures: armv6, armv7 Base SDK: iOS 4.3 Build Active Architecture Only: No Supported Platforms: iphoneos, iphonesimulator Valid Architectures: armv6, armv7 A check with lipo -info libassimp.a approves: Architectures in the fat file: libassimp.a are: armv6 armv7 Can I use this static .a-library in an Android NDK project as well? Do I have to add supported platforms? Or do I have to build

问题 I have a project based off of https://ikaruga2.wordpress.com/2011/06/15/video-live-wallpaper-part-1/, which uses an older copy of the ffmpeg libraries from http://bambuser.com/opensource. Within the C++ code in this project we have the following lines of code: unsigned long long current = GetCurrentTimeInNanoseconds(); avcodec_decode_video(pCodecCtx, pFrame, &frameFinished, packet.data, packet.size); __android_log_print(ANDROID_LOG_DEBUG, "getFrame>>>>", "decode video time: %llu",

问题 I am very new to Android, compiling, and linking in general. I do not know which details are important with my problem, so I will just tell you everything. If you see anything strange or incorrect, please let me know. I built the libcrypto.so and libssl.so libraries in the Android-NDK. I wrote native code which uses a function in openssl.so (and openssl.so uses functions in libssl.so). The code compiles, however I receive an "undefined reference" error when linking: ./obj/local/armeabi/objs

问题 I have a game that uses a callback to Java from C++ to force open the soft keyboard when the user touches the screen. The Java code is simply this: this._inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0); This has worked fine for a while but recently we've been receiving complaints from some Motorola Droid users that the soft keyboard fails to open for them. Since we've only recently started to get these complaints and it's a number of users I'm thinking it was some kind
