The shared library in the document refers to the SO library (shared object). It seems that the purpose of the load method is consistent with our understanding. The executable file should be copied to The APP internal storage is then run.ДЇinally, we can also look at the official API documentation It is also easy to understand that the external storage path such as SD card is a removable (noexec) storage medium and cannot be directly used as the executable directory of the executable file. Try downloading the library to your application's data directory instead, and load it from here. Moreover, using the SD Card as a storage location is a really bad idea, since any other application can modify / delete / corrupt it easily. The SD Card is mounted noexec, so I'm not sure this will work. I found some answers on a Google developer forum So I will not follow up for the moment, interested students can tell me the location of the key code. The last time I looked at it, it was because I needed to look at the specific role of the zoom control information chunk array in Figure 9.

The native method 'nativeLoad' is called in the doLoad method, which should be an error in the Native code. There should be an error when executing the doLoad method, but I have also seen it above. Then load the module corresponding to the SO library in Java (Android Studio now also supports direct compilation of the SO library, but there are many pits, here I choose to manually compile)

View Image in the jniLibs directory of the Android Studio project Locate the directory where the Android.mk file is located on the command line, and run the ndk-build command of the NDK tool to compile the SO library we need Here is an open source Gaussian blur project Android StackBlur (There are many detailed JNI tutorials on the Internet, which will not be repeated here)

Taking a 'picture Gaussian blur' function as an example, if you use Java code to calculate each pixel of the image Bitmap, the overall time-consuming will be very large, so you can consider using JNI.

However, if you use ClassLoader to load the plug-in APK in the SD card, and the plug-in APK contains the SO library, this involves loading the SO library in the plug-in APK, so we also need to know how to load the SO library in the SD card. Unlike what we often say about dynamic loading based on ClassLoader, the SO library is loaded using the System class (this shows that the support for the SO library is also the basic function of Android), so here is a supplementary explanation. so library can also be used in the security field. so library is compiled from C ++ and can only be decompiled into assembly code, which is more difficult to crack than Smali, the. Need work (such as T9 search, or Bitmap decoding, image Gaussian blur processing, etc.). so library dynamically to complete some performance comparisons. The efficiency will be much higher than the Java code executed in the virtual machine.

The latter is generally compiled from C / C ++ code using the NDK tool and runs on the Native layer. so library and calls its packaged method through JNI. The use of JNI in Android actually includes dynamic loading.
