Android 越南元'；t让我们分配**字节

可能重复：

我的应用程序想要分配2529792字节，我在128mb Ram的设备上运行它，它工作正常，然后我在htc上运行ir，有292mb的Ram可用内存，它给出了错误

01-14 21:08:27.972:E/GraphicsJNI（26585）：VM不允许我们分配2529792字节

这是我的LogCat输出

有人能帮我吗？谢谢

您是否尝试过

Manifest.xml

中的

android:largeHeap=“true”

？我还可以看到您正在处理位图，请使用类似以下方法的位图选项：

private Bitmap getBitmap(String path) {

Uri uri = getImageUri(path);
InputStream in = null;
try {
    final int IMAGE_MAX_SIZE = 1200000; // 1.2MP
    in = mContentResolver.openInputStream(uri);

    // Decode image size
    BitmapFactory.Options o = new BitmapFactory.Options();
    o.inJustDecodeBounds = true;
    BitmapFactory.decodeStream(in, null, o);
    in.close();



    int scale = 1;
    while ((o.outWidth * o.outHeight) * (1 / Math.pow(scale, 2)) > 
          IMAGE_MAX_SIZE) {
       scale++;
    }
    Log.d(TAG, "scale = " + scale + ", orig-width: " + o.outWidth + ", 
       orig-height: " + o.outHeight);

    Bitmap b = null;
    in = mContentResolver.openInputStream(uri);
    if (scale > 1) {
        scale--;
        // scale to max possible inSampleSize that still yields an image
        // larger than target
        o = new BitmapFactory.Options();
        o.inSampleSize = scale;
        b = BitmapFactory.decodeStream(in, null, o);

        // resize to desired dimensions
        int height = b.getHeight();
        int width = b.getWidth();
        Log.d(TAG, "1th scale operation dimenions - width: " + width + ",
           height: " + height);

        double y = Math.sqrt(IMAGE_MAX_SIZE
                / (((double) width) / height));
        double x = (y / height) * width;

        Bitmap scaledBitmap = Bitmap.createScaledBitmap(b, (int) x, 
           (int) y, true);
        b.recycle();
        b = scaledBitmap;

        System.gc();
    } else {
        b = BitmapFactory.decodeStream(in);
    }
    in.close();

    Log.d(TAG, "bitmap size - width: " +b.getWidth() + ", height: " + 
       b.getHeight());
    return b;
} catch (IOException e) {
    Log.e(TAG, e.getMessage(),e);
    return null;
}

非常感谢，但我没有使用任何位图，而且HTC比第一款更强大。我认为有一些选择或类似的东西，我不知道确切的情况，我还想只分配2-3MB，我不认为Ram内存一定有问题
