[RazerTexz]

Game used (For testing): Granny v1.8.1 | 32 Bit

Currently trying to make an esp but keep crashing when trying to draw it. I've been trying to fix it for the past 6 hours but can't find the problem, i'll try to fix it again but any help will be appreciated.

Moved the esp initialization to Launcher.java from Menu.java.

Okay i just boiled down the problem to

jmethodID drawtext = _env->GetMethodID(canvasView, "DrawText", "(Landroid/graphics/Canvas;IIIILjava/lang/String;FFF)V");

My first suspicion was the signature but changing it doesn't seem to do anything. I'll look into it more.

void DrawText(Color color, const char *txt, Vector2 pos, float size) {
        if (isValid()) {
            LOGI(OBFUSCATE("DrawText on NepDraw.h called"));
            jclass canvasView = _env->GetObjectClass(_cvsView);
            if (canvasView) {
                LOGI(OBFUSCATE("canvasView class found"));
            }
            jmethodID drawText = _env->GetMethodID(canvasView, "DrawText", "(Landroid/graphics/Canvas;IIIILjava/lang/String;FFF)V");
            if (drawText) {
                LOGI(OBFUSCATE("drawtext method found"));
            }
            LOGI(OBFUSCATE("Calling void method"));
            _env->CallVoidMethod(_cvsView, drawText, _cvs, (int) color.a, (int) color.r, (int) color.g, (int) color.b, _env->NewStringUTF(txt), pos.X, pos.Y, size);
            LOGI(OBFUSCATE("SUCCESS"));
        }
    }

All logs was called successfully, except for "drawtext method found" and "SUCCESS"

Fixed it by adding

-keep public class com.android.support.ESPView {
    public void DrawText(android.graphics.Canvas, int, int, int, int, java.lang.String, float, float, float);
}

in proguard-rules.pro (i'm so stupid)
