NAME

6       al_android_get_jni_env - Allegro 5 API
7

SYNOPSIS

9              #include <allegro5/allegro_android.h>
10
11              JNIEnv *al_android_get_jni_env(void)
12

DESCRIPTION

14       Returns  the Android JNI environment used by Allegro to call into Java.
15       As a convenience this function provides it to the user so there  is  no
16       need to obtain it yourself.
17
18       For  example  if  you have a Java method "void send(String message)" in
19       your activity class, you could call it like this from C code:
20
21              JNIEnv * env = al_android_get_jni_env();
22              jclass class_id = (* env)->GetObjectClass(env, al_android_get_activity());
23              jmethodID method_id = (* env)->GetMethodID(env, class_id, "send",
24                  "(Ljava/lang/String;)V");
25              jstring jdata = (* env)->NewStringUTF(env, "Hello Java!");
26              (* env)->CallVoidMethod(env, al_android_get_activity(), method_id, jdata);
27              (* env)->DeleteLocalRef(env, jdata);
