问题描述
我创建动态壁纸应用程序，可以完美运行在xhdpi和LDPI设备，而是越来越强制关闭问题，华电国际和基于手机MDPI
I am creating live wallpaper app, that runs perfectly on xhdpi and ldpi device, but getting force close issue in hdpi and mdpi based handset.
当我们点击设置壁纸它加载在preVIEW屏幕图像得到它崩溃，甚至当我们改变从应用程序设置。
It loads image in preview screen when we click "set wallpaper" it get crashed and even when we change settings from app.
以上两个条件使应用程序来强制关闭。
Above two conditions make app to force close.
看起来的OutOfMemoryError
错误是不相符
下面是我的code：
pixeltwo.java
public class pix11two extends SurfaceView {
private pix11three three;
int fps;
Bitmap mBitmap;
int country_flag;
public pix11two(Context context, int fps, int country) {
super(context);
this.fps = fps;
country_flag = country;
DisplayMetrics displayMetrics = new DisplayMetrics();
displayMetrics = context.getResources().getDisplayMetrics();
int displayWidth = displayMetrics.widthPixels;
int displayHeight = displayMetrics.heightPixels;
if (mBitmap != null)
mBitmap.recycle();
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 1;
options.inPurgeable = true;
if (country_flag > 1) {
if (country_flag == 2) {
mBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.yellow, options);
}
if (country_flag == 3) {
mBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.orange, options);
}
if (country_flag == 4) {
mBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.green, options);
}
if (country_flag == 5) {
mBitmap = BitmapFactory.decodeResource(getResources(),

}

mBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.purple, options);
}
if (country_flag == 7) {
mBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.pink, options);
}
} else {
mBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.blue, options);
}
three = new pix11three(mBitmap, displayWidth, displayHeight, 0, 0, fps,
10);
}

canvas.drawColor(Color.BLACK);
three.draw(canvas);

// Comparing with preference value and array value

@Override

mHandler.removeCallbacks(mDrawPattern);
if (mVisible) {
mHandler.postDelayed(mDrawPattern, 1000 / 75);
}
}
}
}
我还没有显示pixelthree类，但我认为两类被sufficent来解决这个问题。
I havent shown pixelthree class, but i think two class are sufficent to solve the issue.
任何帮助，将AP preciated。
Any Help would be appreciated.
感谢
推荐答案
我已经通过降低样本规模为2审判，它为我工作。
I have tried by decreasing sample size to 2 and it worked for me..
BitmapFactory.Options选项=新BitmapFactory.Options（）;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2;
options.inPurgeable = true
