问题 I have an Android app that needs to run a custom binary app I wrote. I already built the binary using ndk and packaged it in the apk under res/raw I did something like this to first run the su process. Process process; process = Runtime.getRuntime().exec("su"); DataOutputStream os = new DataOutputStream(process.getOutputStream()); What do I do after this to run the binary from resources? There was another question here that suggested the use of AssetManager but I don't understand how to do it

问题 We are developing an indie game for android and would like the user to choose his nickname. We have chosen to use the Native Activity that is provided by the NDK as that seemed to be the easiest way to go. The first problem we've encountered with the keyboard was that the function ANativeActivity_showSoftInput() seems to do nothing at all (as described e.g. here), so we bring up the keyboard using JNI calls to function: static void showKeyboard(Activity activity) { String s = Context.INPUT

问题 I am trying to decode h264 video using ffmpeg and stagefright library. I'm using this example. The example shows how to decode mp4 files, but i want to decode only h264 video. Here is piece of my code.. AVFormatSource::AVFormatSource(const char *videoPath) { av_register_all(); mDataSource = avformat_alloc_context(); avformat_open_input(&mDataSource, videoPath, NULL, NULL); for (int i = 0; i < mDataSource->nb_streams; i++) { if (mDataSource->streams[i]->codec->codec_type == AVMEDIA_TYPE_VIDEO)

问题 Hi I'm trying to build a custom android kernel. I was told to $ export CROSS_COMPILE=/home/user/adb-fastboot/kernel-custom/android-ndk-r21d/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi- with nothing after the dash But when I $ make clean && make mrproper I get make: /home/user/adb-fastboot/kernel-custom/android-ndk-r21d/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc: Command not found So when I assume that make

问题 I'm trying to cross-compile a Rust library to 4 Android targets (i386, x86_64, armv7, and aarch64) from Windows. I have set up Android NDK toolchain for these targets and tried to compile my library with help of this tutorial. I think I've set up the toolchain correctly, and I'm able to successfully execute aarch64-linux-android-clang in the terminal. Build log: cargo build --target aarch64-linux-android --release --verbose Fresh cc v1.0.28 Fresh autocfg v0.1.1 Fresh version_check v0.1.5
