首先在src同級目錄下創(chuàng)建libs目錄講需要的.so復(fù)制到這里效果如圖這里寫圖片描述

然后在app級別的build.gradle配置lib路徑，效果如果這里寫圖片描述完整代碼如下：

apply plugin: 'com.android.application'android { compileSdkVersion 24 buildToolsVersion "25.0.1" defaultConfig { applicationId "com.liberation.idcarread" minSdkVersion 15 targetSdkVersion 24 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false PRoguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } task nativeLibsToJar(type: Zip, description: "create a jar archive of the native libs") { destinationDir file("$projectDir/libs") baseName "Native_Libs2" extension "jar" from fileTree(dir: "libs", include: "**/*.so") into "lib" } tasks.withType(javaCompile) { compileTask -> compileTask.dependsOn(nativeLibsToJar) } sourceSets { main { jniLibs.srcDirs = ['libs'] } }}dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) compile 'com.android.support:appcompat-v7:24.2.1' testCompile 'junit:junit:4.12'}

至此配置完成點擊sync即可正常使用。編譯運行過程遇到*.so: has text relocations 說明編譯.so文件時使用了較低版本sdk 版本此時降低build.gradle的targetSdkVersion 版本為22以及以下即可我們這里改為22 最終效果如下

運行時又出現(xiàn)一個異常

**java.lang.UnsatisfiedLinkError: No implementation found for int com.liberation.idcarread.ivsign.IDCReaderSDK.wltInit(java.lang.String) (tried Java_com_liberation_idcarread_ivsign_IDCReaderSDK_wltInit and Java_com_liberation_idcarread_ivsign_IDCReaderSDK_wltInit__Ljava_lang_String_2)**

解決方法：按照官方Demo放好包名路徑。包名一定要跟原來的一模一樣負責無法調(diào)用！
