问题 I am interested in demoing printf vulnerabilities via an NDK app. To be clear, I am aware that to log in the console we can use __android_log_print(ANDROID_LOG_DEBUG, "LOG_TAG", "Print : %d %s",someVal, someStr); . I have tried it and I know it works. But I explicitly want to demo the vulnerabilities of printf() , specifically to use the %n specifier to write to a pointed location. Is there a way to make printf() work to this effect or is it possible to achieve this via __android_log_print()

问题 I fetch a project from Windows to my local Mac environment. You see there, under the Gradle Script , the local.properties : ndk.dir=D\:\\sdk\\ndk-bundle sdk.dir=/Users/lisa/software/android-sdk-macosx you see there has the ndk.dir and sdk.dir , the latter is my new Mac SDK path, but the ndk.dir did not change now. from the D\:\\sdk\\ndk-bundle , whether we know the ndk-bundle should be under the sdk path( /Users/lisa/software/android-sdk-macosx )? but in the /Users/lisa/software/android-sdk

问题 I'm trying to use the Eigen implementation of Levenberg Marquardt algorithm on a Android application. In order to use Eigen, I'm using Android NDK and jni. I've already tested Eigen with simple calculations (like matrix creation and vector sums) and it works perfectly. However, when I tried to use the Levenberg Marquardt algorithm I got some errors on the LevenbergMarquardt.h file from Eigen's library. First, here is my code. I based on this code: Eigen::MatrixXd matrix(count, 3); for (int i

问题 My problem is that I fail to find some proper documents/guides to follow in order to set up my environment correctly. Basically I am using Android Studio 1.3.2 (latest stable as of 22nd september 2015) with Gradle Experimental version 2.5. I followed Google official documentation here : http://tools.android.com/tech-docs/new-build-system/gradle-experimental but I find no help when it comes to JNI Libs. I tried many other solutions but they do not work because they seem to be obsolete. I have
