我做了一个小动态壁纸。我想将它上传到市场并获得我需要指定 api 级别的信息。但是当我设置

<uses-sdk android:minSdkVersion="7" />

在关闭标签后的清单中，壁纸只是在加载时崩溃。我没有在两个编译之间更改任何其他内容，并且在没有标签的情况下运行良好。该错误发生在运行墙纸的 opengl 线程深处，因此异常消息并没有真正的帮助。至少我不知道那里可能会崩溃。

我希望有人可以帮助我。

OK, as nobody answered and I figured it out myself, here is the answer:

OpenGL seems to have different specifications regarding buffers on different sdk versions. It is strange that the tag actually affects it, as the code was compiled against the api version 7 anyway.

So basically all my opengl buffers, that previously where defined by:

FloatBuffer.wrap(float[]);

now have to be defined as native order direct buffers and filled via:

BufferName.put(float[]);
