libcom_wuba_uc_rsa.so.zip public class RsaCryptService { private static final String TAG = "RsaCryptService"; private static boolean initSuccess;

public static String doEncrypt(String str) {
    loadSoAndInit();
    try {
        if (TextUtils.isEmpty(str)) {
            Log.w("Log", "待加密串是空！！");

private static native void init(Context context);

private static void loadSoAndInit() {

}

下面是我java代码 // 密码加密 public static String encrypt(String info) throws IOException { // 1、需要调用的so文件所在路径 String soFilePath = "/disk/apps/wubaapp/libcom_wuba_uc_rsa.so"; // 2、需要调用函数所在的Java类完整路径，比如a/b/c/d等等，注意需要用/代替. String classPath = "com/wuba/uc/RsaCryptService"; // 3、需要调用函数的函数签名，我这里调用EncryptUtils中的getGameKey方法，由于此方法没有参数列表，所以不需要传入 String methodEncryp = "encrypt([B)Ljava/lang/String;"; // 输出getGameKey方法调用结果 WuBaAppSignUtils encryptUtilsJni = new WuBaAppSignUtils(soFilePath, classPath); //调用native init方法 String methodInit = "init(Landroid/content/Context;)V"; encryptUtilsJni.myJni(methodInit, encryptUtilsJni.vm.resolveClass("android/content/Context").newObject(null)); byte[] bytes = (byte[]) null; if(StringUtils.isNotBlank(info)) { bytes = info.getBytes(); } logger.info("加密接收到的字符为info:[{}]", info); String encryption = encryptUtilsJni.myJni(methodEncryp, new ByteArray(encryptUtilsJni.vm, bytes)); logger.info("加密结果:[{}]", encryption); encryptUtilsJni.destroy(); return encryption; }

楼主解决了吗？我也是Context传参到so里，报错null为空
