Приложение вылетает без ошибки

Question

В своём приложении я произвожу объёмные вычисления, а именно сравнения соответствующих пикселей на фото. Обе фотографии всегда имеют разрешение 1440х900. Это всё производится в отдельном потоке, в итоге приложение вылетает без ошибки и обои на смартфоне меняются всё время на одни и те же. С чем это связано?

    private void macPRC(Thread loading) {
    loading.start();
    photo();
    Thread DH = new Thread(() -> {
        prcD = eql(DBmp);
        prcH = eql(HBmp);
    });
    Thread JMk = new Thread(() -> {
        prcJ = eql(JBmp);
        prcMk = eql(MkBmp);
    });
    Thread MlP1 = new Thread(() -> {
        prcMj = eql(MlBmp);
        prcP1 = eql(P1Bmp);
    });
    Thread P2S = new Thread(() -> {
        prcP2 = eql(P2Bmp);
        prcS = eql(SBmp);
    });
    DH.start();
    JMk.start();
    while(DH.isAlive() || JMk.isAlive()){
        try {
            Thread.sleep(1000);
        } catch (Exception ignored){}
    }
    MlP1.start();
    P2S.start();
    while(MlP1.isAlive() || P2S.isAlive()){
        try {
            Thread.sleep(1000);
        } catch (Exception ignored){}
    }
    int max1 = Math.max(prcH, prcD);
    int max2 = Math.max(max1, prcJ);
    int max3 = Math.max(max2, prcMk);
    int max4 = Math.max(max3, prcMl);
    int max5 = Math.max(max4, prcP1);
    int max6 = Math.max(max5, prcP2);
    PRC = Math.max(max6, prcS);
    isLoading = false;
    motionHome.transitionToEnd();
}

Вот сам метод eql, в неё передаются Bitmap изображения которые уже есть в проекте, и она сравнивает каждое из них с изображением которое уже выбрано в галлерее.

    private int eql(Bitmap modelH){
    int k = 0;
Bitmap model = modelH;
model = reSize(model);

int width = model.getWidth(), height = model.getHeight();

for(int i = 0; i < width; i++){
    for(int j = 0; j < height; j++){
        int pxlModel = model.getPixel(i, j);
        int pxlImage = imageBitmap.getPixel(i, j);
        if(pxlModel == pxlImage){
            k++;
        }
    }
}

int sum = width * height;

double it = k * 100 * 2.1;

double prc = (it / sum) + 11;

if (prc > 100){
    prc  = 100;
}

return (int)prc;

}

Метод maxPRC запускается в отдельном потоке.
