Android：3240016字节分配内存不足

我总是要面对这个问题。在同一个问题上讨论了很多问题（即，等等）。既然我对Android还很幼稚，有人能帮我吗

使用更高效的数据表示，而不需要如此大的分配。也许您可以在设备外部压缩/预处理web服务上的数据

如果这不是一个选项，您可以构建自己的平台映像并更改每个应用程序的内存限制设置

如果（2）不是您的选项。您可以编写一个本机库，它将为您保存数据。内存限制仅适用于Java/Dalvik分配。本机代码可以做它想做的任何事情

建议使用imageloader。
您使用的每个位图的内存成本为4mb。可以通过以下方法使用调整大小的位图

private Bitmap decodeBitmap(int targetWidth, int targetHeight) throws IOException {
    final BitmapFactory.Options opts = new BitmapFactory.Options();
    opts.inJustDecodeBounds = true;
    BitmapFactory.decodeStream(getAssets().open("frog.jpg"), null, opts);

    opts.inSampleSize = getBitmapSampleSize(opts, targetWidth, targetHeight);

    opts.inJustDecodeBounds = false;

    return BitmapFactory.decodeStream(getAssets().open("frog.jpg"), null, opts);
}

private int getBitmapSampleSize(BitmapFactory.Options opts, int targetWidth, int targetHeight) {
    final int width = opts.outWidth;
    final int height = opts.outHeight;
    Log.d("tag", "bitmap's size is " + width + ", " + height);
    int inSampleSize = 1;

    if (height > targetHeight || width > targetWidth) {
        if (width > height) {
            inSampleSize = (int) Math.floor((float)height / (float)targetHeight);
        } else {
            inSampleSize = (int) Math.floor((float)width / (float)targetWidth);
        }
    }
    Log.d("tag", "target size is " + targetWidth + ", " + targetHeight);
    Log.d("tag", "inSampleSize is " + inSampleSize);
    return inSampleSize;
}

您可以尝试将此行添加到清单文件中。它将为您的应用程序分配大内存

android:largeHeap="true"

谢谢你的回复。您能否根据我的场景向我提供选项3的示例代码，我将base64字符串解码为图像并在imageview中显示相同的内容？
private Bitmap decodeBitmap(int targetWidth, int targetHeight) throws IOException {
    final BitmapFactory.Options opts = new BitmapFactory.Options();
    opts.inJustDecodeBounds = true;
    BitmapFactory.decodeStream(getAssets().open("frog.jpg"), null, opts);

    opts.inSampleSize = getBitmapSampleSize(opts, targetWidth, targetHeight);

    opts.inJustDecodeBounds = false;

    return BitmapFactory.decodeStream(getAssets().open("frog.jpg"), null, opts);
}

private int getBitmapSampleSize(BitmapFactory.Options opts, int targetWidth, int targetHeight) {
    final int width = opts.outWidth;
    final int height = opts.outHeight;
    Log.d("tag", "bitmap's size is " + width + ", " + height);
    int inSampleSize = 1;

    if (height > targetHeight || width > targetWidth) {
        if (width > height) {
            inSampleSize = (int) Math.floor((float)height / (float)targetHeight);
        } else {
            inSampleSize = (int) Math.floor((float)width / (float)targetWidth);
        }
    }
    Log.d("tag", "target size is " + targetWidth + ", " + targetHeight);
    Log.d("tag", "inSampleSize is " + inSampleSize);
    return inSampleSize;
}
