我之前曾在我的 android 应用程序中寻求过有关 OutOfMemoryError 问题的帮助。由于我还没有解决方案，所以我需要再次请您为我提供解决方案。我在几个真正的安卓设备上测试了我的应用程序。但在三星 Galaxy S3 android 4.0.4 我有 OutOfMemoryError 问题。Logcat 消息如下。谢谢你。

使用下面的方法来减小图像的大小。由于图像尺寸过大，您会收到 OutOfMemory 错误。

public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId,
        int reqWidth, int reqHeight) {

    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    BitmapFactory.decodeResource(res, resId, options);

    // Calculate inSampleSize
    options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    return BitmapFactory.decodeResource(res, resId, options);
}

public static int calculateInSampleSize(
            BitmapFactory.Options options, int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {
        if (width > height) {
            inSampleSize = Math.round((float)height / (float)reqHeight);
        } else {
            inSampleSize = Math.round((float)width / (float)reqWidth);
        }
    }
    return inSampleSize;
}

并在您的代码中使用

mImageView.setImageBitmap(
    decodeSampledBitmapFromResource(getResources(), R.id.myimage, 100, 100));

有关更多详细信息，我建议您必须阅读Android开发者网站提供的关于 Bitmap 效率的开发者信息。

由于某种原因，您没有足够的内存来创建Bitmap. 您可以将您的Bitmap创作包装成try { ... } catch(OutOfMemoryError) {}

在 catch 块或其他地方，您可能希望缩小位图，然后它可能会创建类似

bmp = Bitmap.createBitmap(bmp, bmp.getWidth()/2, bmp.getheight()/2, true)
