al_android_get_jni_env - Allegro 5 API
-
#include <allegro5/allegro_android.h>
JNIEnv *al_android_get_jni_env(void)
Returns the Android JNI environment used by Allegro to call into Java. As a
convenience this function provides it to the user so there is no need to
obtain it yourself.
For example if you have a Java method “void send(String
message)” in your activity class, you could call it like this from C
code:
-
JNIEnv * env = al_android_get_jni_env();
jclass class_id = (* env)->GetObjectClass(env, al_android_get_activity());
jmethodID method_id = (* env)->GetMethodID(env, class_id, "send",
"(Ljava/lang/String;)V");
jstring jdata = (* env)->NewStringUTF(env, "Hello Java!");
(* env)->CallVoidMethod(env, al_android_get_activity(), method_id, jdata);
(* env)->DeleteLocalRef(env, jdata);
