JNIEnv\ *al_android_get_jni_env(void)

.SH DESCRIPTION
.PP
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.
.PP
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:
.IP
.nf
\f[C]
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);
