JNI/NDK Development Guide (iii) -- ing between JNI data types and Java data types, ndkjni Reprinted please indicate the source: http://blog.csdn.net/xyang81/article/details/42047899 When we call a Java native method, how does the parameter in the method pass to the local function in C/C ++? How are the parameters in the Java method converted from those in the C

are derived from Jobject, using the inheritance structure characteristics of C + +, using the corresponding type.For example, see the following:Class _jobject {}; Class _jclass:public _jobject {}; Class _jstring:public _jobject {}; Class _jarray:public _jobject {}; Class _jbooleanarray:public _jarray {}; Class _jbytearray:public _jarray {}; ...2. The JNI hypothesis is written using C language. All reference types use Jobject, and other reference types are defined using typedef once

A more convincing approach is to directly query the repository to see if the new data exists. You can open the repository as read-only state, cancel the log application first, and then execute the
