Body
You haven't mentioned the target class name and the target method signature. So consider, for example, <a href="http://developer.android.com/reference/java/lang/StringBuilder.html#append%28java.lang.String%29" rel="nofollow">java.lang.StringBuilder.append(java.lang.String)</a> method. <pre><code>// First lets assume you have already received the next variables void foo( JNIEnv* env, jobject obj ) { // Call StringBuilder.append() method } </code></pre> Now you need the class name and the method signature (according to <a href="http://docs.oracle.com/javase/1.5.0/docs/guide/jni/spec/types.html" rel="nofollow">docs</a>) <pre><code>static char const StringBuilder_ClassName = "java/lang/StringBuilder"; static char const StringBuilder_append_MethodName = "append"; static char const StringBuilder_append_MethodSignature = "(Ljava/lang/String;)Ljava/lang/StringBuilder;"; </code></pre> To call java method from JNI code you should obtain <code>jmethodID</code> <pre><code>static jclass StringBuilder_Class = 0; static jmethodID StringBuilder_append_Method = 0; void Init( JNIEnv* env ) { if( StringBuilder_Class == 0 ) { StringBuilder_Class = (*env)->FindClass( env, StringBuilder_ClassName ); // TODO: Handle error if class not found } if( StringBuilder_append_Method == 0 ) { StringBuilder_append_Method = (*env)->GetMethodID( env, StringBuilder_Class, StringBuilder_append_MethodName, StringBuilder_append_MethodSignature ); // TODO: Handle error if method not found } } void foo( JNIEnv* env, jobject obj ) { Init(); char* str; // str = ...; jstring jString = (*env)->NewStringUTF( env, str ); // Because StringBuild.append() returns object, you should call CallObjectMethod jobject ret = (*env)->CallObjectMethod( env, obj, jString ); // Here you can release local references, i.e. // (*env)->DeleteLocalRef( env, ret ); // (*env)->DeleteLocalRef( env, jString ); // But it is not necessary. Local references are released automatically when // thread returns from JNI code to Java code. // So you can ignore the returned value and not to release the jString local // reference, i.e. just call // (*env)->CallObjectMethod( env, obj, jString ); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
