Android 即使在对位图图像进行采样后，应用程序也会在模拟器中崩溃

我正在模拟器中测试我的应用程序。 模拟器设备大小-480 x 854 图像大小-1280 x 720 样本量=1这来自Android参考中解释的流程-

当我触发此活动时，应用程序运行正常，当我遍历到下一个活动并返回时，应用程序会因OOM崩溃。我已经按照android手册中解释的过程高效地加载位图，但仍然失败 backgoundImage=getAssetImagegetApplicationContext，backgroundhomepage； 请帮忙

问题1：这种大小的设备的最小堆大小是多少？ 问题2：我需要改变样本量吗？ 问题3：我还需要遵循其他步骤吗

代码： 日志：

你可以这样得到你的堆大小

Runtime rt = Runtime.getRuntime();
long maxMemory = rt.maxMemory();
Log.v("onCreate", "maxMemory:" + Long.toString(maxMemory));

至于其他问题，我帮不了你。抱歉。

我正在使用此简单代码从gallery应用程序中获取任何图像，确保图像方向正确

BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
        bmpFactoryOptions.inJustDecodeBounds = true;
        bmpFactoryOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;
        try {
            bmp = BitmapFactory
                    .decodeStream(
                            getContentResolver().openInputStream(
                                    imageFileUri), null, bmpFactoryOptions);
            bmpFactoryOptions.inSampleSize = 4;
            System.out.println("The Quality is" + quality);
            bmpFactoryOptions.inJustDecodeBounds = false;
            bmp = BitmapFactory
                    .decodeStream(
                            getContentResolver().openInputStream(
                                    imageFileUri), null, bmpFactoryOptions);

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        String[] orientationColumn = { MediaStore.Images.Media.ORIENTATION };
        @SuppressWarnings("deprecation")
        Cursor cur = managedQuery(imageFileUri, orientationColumn, null,
                null, null);
        int orientation = -1;
        if (cur != null && cur.moveToFirst()) {
            orientation = cur.getInt(cur
                    .getColumnIndex(orientationColumn[0]));
        }
        Matrix matrix = new Matrix();
        matrix.postRotate(orientation);
        bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(),
                bmp.getHeight(), matrix, true);
        view.setImageBitmap(bmp);

欢迎您使用。

这并不总是好的，因为它会占用其他应用程序可能需要的内存。我欢迎任何其他答案
