java - 运行 Android KitKat 代码在 Lollipop 设备上崩溃

Question

我一直在开发一款社交媒体应用程序，到目前为止，它在运行 KitKat 及更低版本的所有设备上运行良好。

我尝试在 Lollipop 和更高版本的操作系统上运行它，但它崩溃了。

经过数周的调试，我得到的仍然是一条与我的代码无关的错误消息:

我在应用程序中绝对不使用 native 代码。

可能是什么原因？

我曾尝试在我的代码中关闭硬件加速，但这没有帮助。当我试图打开联系人列表时发生崩溃。我的联系人列表只有 3 张图片，而且它们的大小都在几十 KB。

最后，这是加载位图的代码:

public static Bitmap decodeSampledBitmapFromFile(File data,
                                                     int reqWidth, int reqHeight) {

        // First decode with inJustDecodeBounds=true to check dimensions
        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(data.getAbsolutePath(), options);

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

        // Decode bitmap with inSampleSize set
        options.inJustDecodeBounds = false;
        return BitmapFactory.decodeFile(data.getAbsolutePath(), options);
    }

是什么导致了这次崩溃？

更新

我注意到系统似乎内存不足或可能是 native 代码中发生某些事情的结果？

Answer 1

加载位图时，您是否检查设备的内存？我知道您正在计算 inSampleSize，但我遇到了同样的问题，因为我将错误的值传递给参数 reqWidth 和 reqHeight，当然，inSampleSize 太大并导致设备内存崩溃。这个问题出现在照片库中。

希望对您有所帮助!!
