How to get input from soft keyboard on android

[Zahon7]

Does anyone have experience getting input from a soft keyboard?

This is my current setup:

main.c:

#include "raylib.h"
#include <stdlib.h>

struct android_app *androidApp;

int lastKey = 0;

static JavaVM* jvm = NULL;
static jobject nativeLoaderInstance;

JNIEXPORT jint JNI_OnLoad(JavaVM* vm, void* reserved) {
    JNIEnv* env;

    if (vm->GetEnv((void **)&env, JNI_VERSION_1_6) != JNI_OK) {
        return JNI_ERR;
    }

    jvm = vm;

    jclass nativeLoaderClass = env->FindClass("com/raylib/game/NativeLoader");
    jmethodID getInstanceMethod = env->GetStaticMethodID(nativeLoaderClass, "getInstance", "()Lcom/raylib/game/NativeLoader;");
    jobject instance = env->CallStaticObjectMethod(nativeLoaderClass, getInstanceMethod);
    nativeLoaderInstance = env->NewGlobalRef(instance);

    env->GetJavaVM(&jvm);

    return JNI_VERSION_1_6;
}

void ReleaseNativeLoader(void) {
    JNIEnv* env;
    jvm->AttachCurrentThread(&env, NULL);

    if(nativeLoaderInstance != NULL) {
        env->DeleteGlobalRef(nativeLoaderInstance);
        nativeLoaderInstance = NULL;
    }

    jvm->DetachCurrentThread();
}

void SetKeyboard(bool show) {
    JNIEnv* env;
    jvm->AttachCurrentThread(&env, NULL);

    if (nativeLoaderInstance != NULL) {
        jclass nativeLoaderClass = env->GetObjectClass(nativeLoaderInstance);
        if(show) {
	        jmethodID method = env->GetMethodID(nativeLoaderClass, "showKeyboard", "()V");
	        env->CallVoidMethod(nativeLoaderInstance, method);
	    } else {
	    	jmethodID method = env->GetMethodID(nativeLoaderClass, "hideKeyboard", "()V");
	        env->CallVoidMethod(nativeLoaderInstance, method);
	    }
    }

    jvm->DetachCurrentThread();
}

int main(void) {
	androidApp = GetAndroidApp();

	InitWindow(0, 0, "Test");
	SetTargetFPS(60);

	SetKeyboard(true);

	while(!WindowShouldClose()) {

		AInputEvent* event = NULL;

    	        if(AInputQueue_getEvent(androidApp->inputQueue, &event) >= 0) {
    	        	if(event != NULL) {
	    		        if (AInputEvent_getType(event) == AINPUT_EVENT_TYPE_KEY) {
			        	lastKey = AKeyEvent_getKeyCode(event);
		        	}
	    		        AInputQueue_finishEvent(androidApp->inputQueue, event, 1);
    		        }
    	        }

	        BeginDrawing(); {
		        ClearBackground(BLACK);

		        char text[10];
		        sprintf(text, "%i", lastKey);
		        DrawText(text, 0, 0, 50, WHITE);
	        } EndDrawing();
        }

	ReleaseNativeLoader();
	CloseWindow();

	return 0;
}

NativeLoader.java:

package com.raylib.game;
import android.os.Bundle;
import android.view.inputmethod.InputMethodManager;
import android.content.Context;

public class NativeLoader extends android.app.NativeActivity {
    private static NativeLoader instance;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        instance = this;
        System.loadLibrary("main");
    }

    public static NativeLoader getInstance() {
        return instance;
    }

    public void showKeyboard() {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(this.getWindow().getDecorView(), InputMethodManager.SHOW_FORCED);
    }

    public void hideKeyboard() {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(this.getWindow().getDecorView().getWindowToken(), 0);
    }
}

But this doesn't seem to be working.

PS: I edited the raylib.h header and added the GetAndroidApp() definition

EDIT: It is working, but it is super slow and unresponsible
