我正在尝试在 AOSP 中构建一个应用程序,我的开发工具包具有 HDPI 密度,我使用以下代码片段对其进行了双重验证:
switch (getResources().getDisplayMetrics().densityDpi) {
case DisplayMetrics.DENSITY_LOW:
Log.d(TAG, "\n\n\n\n LDPI \n\n\n\n");
break;
case DisplayMetrics.DENSITY_MEDIUM:
Log.d(TAG, "\n\n\n\n MDPI \n\n\n\n");
break;
case DisplayMetrics.DENSITY_HIGH:
Log.d(TAG, "\n\n\n\n HDPI \n\n\n\n");
// ...
break;
case DisplayMetrics.DENSITY_XHIGH:
Log.d(TAG, "\n\n\n\n XDPI \n\n\n\n");
// ...
break;
}
当我在 Android 文件系统中构建我的应用程序时,如果我运行它,那么我会收到以下错误:

我所有的可绘制资源都在 drawable-hdpi 中。
但是,如果我将 drawables 放在所有 drawable-* 文件夹中,那么应用程序就会运行。但随后用户界面变得分散。
有没有人知道,问题可能是什么。我是否必须在 Android.mk 中添加任何变量或标志
=========edit=========
The app works fine if I build with eclipse. And run on the same device.
Therefore issue might be in building app along with AOSP.

任何帮助将不胜感激。
