JNI DETECTED ERROR IN APPLICATION: input is not valid Modified UTF-8: illegal start byte 0x9e 解决方案

在vivo设备上调用

jstring str = env->NewStringUTF(charResult);

出现闪退问题报错：JNI DETECTED ERROR IN APPLICATION: input is not valid Modified UTF-8: illegal start byte 0x9e

解决方案：

不使用NewStringUTF 从网上找了一个const char* 转jstring的函数具体如下：


jstring str2jstring(JNIEnv *env, const char *pat) {//定义java String类 strClassjclass strClass = (env)->FindClass("java/lang/String");//获取String(byte[],String)的构造器,用于将本地byte[]数组转换为一个新StringjmethodID ctorID = (env)->GetMethodID(strClass, "<init>", "([BLjava/lang/String;)V");//建立byte数组jbyteArray bytes = (env)->NewByteArray(strlen(pat));//将char* 转换为byte数组(env)->SetByteArrayRegion(bytes, 0, strlen(pat), (jbyte*)pat);// 设置String, 保存语言类型,用于byte数组转换至String时的参数jstring encoding = (env)->NewStringUTF("utf-8");//将byte数组转换为java String,并输出return (jstring)(env)->NewObject(strClass, ctorID, bytes, encoding);
}

调用代码如下：

    const char *charResult = result.c_str();//jstring str = env->NewStringUTF(charResult); //此代码在vivo手机上出现闪退jstring str = str2jstring(env,charResult);

参考博客转：JNI jstring与c++字符串类型转换函数
