AndroidGradle ArchitectureAndroid Application, you need. So LibraryFor special processing, compilation is correct and usage is incorrect because it cannot be found. The common usage is that different CPUs have different libraries, including:Armeabi, mips, x86.
Error:

java.lang.UnsatisfiedLinkError: Couldn't load weibosdkcore from loader dalvik.system.PathClassLoader[DexPathList[[zip file /data/app/xxx.apk],nativeLibraryDirectories=[/data/app-lib/xxx-2, /vendor/lib, /system/lib]]]: findLibrary returned null

There are two solutions: 1. Generate the ". so" library and introduce the jar into the project. Pay attention to the directory sequence:

-lib--armeabi---xxx.so

Command:

jar cvf xxx_cpu.jar ./lib

Load it to the application;
2. Use gradle to configure Android {}To add:

    //noinspection all    task copyNativeLibs(type: Copy) {        // third party lib so        from(new File(projectDir, 'libs')) { include 'armeabi/*.so' }        into new File(buildDir, 'native-libs')    }    tasks.withType(JavaCompile) {        compileTask ->            //noinspection all            compileTask.dependsOn copyNativeLibs    }    //noinspection all    tasks.withType(com.android.build.gradle.tasks.PackageApplication) {        pkgTask ->            pkgTask.jniFolders = new HashSet
 
  ()            pkgTask.jniFolders.add(new File(buildDir, 'native-libs'))    }
