In the ANE if the SDK calls the so library, you need to place the so library under the ANE Android-arm/lib/armeabi (debug mode) or armeabi-v7a (release mode).You can put an ADT code to illustrate the problem:Whether M_configtype.equals ("apk") is a release mode(Hascaptiveruntime () with Run-timeif ((M_configtype.equals
Many friends in the development of the Android JNI, will encounter Findlibrary returned null error, for some reason, so is not packaged into the APK. The following is an analysis of the cause of the error and platform compatibility issues.first, there is no reason to pack so into the APK. When you find the findlibrary returned null error, the most straightforward solution is to unzip the APKto see the APK x86, Arm
1. After OpenCV is transplanted to android, an error occurs during development: android fatal signal 11 (SIGSEGV) at 0 xdeadbaad (code = 1 ). some people say that AsyncTask is used in the program. It happens that it is actually used in my program. However, after careful research, it is found that if the error is: android fatal signal 11 (SIGSEGV) at 0 xdeadbaad (

,mips64 and x86_64 (from 2014), each of which is associated with a corresponding ABI. On an Android system, each CPU architecture corresponds to a abi:armeabi,armeabi-v7a,x86,mips,arm64-v8a,mips64,x86_64. The names of these packages cannot be changed casually.While we are in the development, As much as possible, each ABI-optimized. So file should not be mixed, ac

A slightly larger project will use a third-party library, so there will inevitably be a different CPU architecture for the phone. So library files ' x86 ', ' x86_64 ', ' MIPS ', ' Mips64 ' Armeabi ', ' armeabi-v7a ', ' arm64-v8a ' But not all third-party libraries will adapt to all the CPU architecture, I have to test the use of a reduced performance and reduce t
