android:android 2.2上opengl es2.0的着色语言出错

我的申请有问题。是一个简单的atm应用程序，使用opengl es2.0，运行在安卓2.2设备HTC sense上。我可以在我的4.0.3模拟器上运行应用程序，也可以在运行安卓4.0的设备上运行应用程序

在android 2.2上运行时，我出现以下错误：

> FATAL EXCEPTION: GLThread 9
java.lang.RuntimeException: Error compiling shader: 
SimpleShader.loadShader(SimpleShader.java:87)
SimpleShader.<init>(SimpleShader.java:54)
etc

---

该应用程序在我最新的安卓4.0+设备上运行良好

您是否考虑在安卓2.2设备和安卓4.0+设备上检查OpenGL ES GLSL版本？

您可以使用

GLES20.glGetString（GLES20.GL\u SHADING\u LANGUAGE\u版本）

很抱歉，我在eclipse上使用了这个，但无法识别GL\u SHADING\u LANGUAGE\u版本枚举类型很抱歉我找到了它。。。我需要调用GLES20.GL_SHADING_LANGUAGE_version我不确定这是否会有多大帮助，但我只是想看看你可能正在android 2.3设备上的旧GLSL版本上编译着色器。你能指出你在顶点/片段着色器的哪一行出现错误吗？那一行：抛出新的RuntimeException(编译着色器时出错：“+Error”）。在上面的代码中。如何将上面的着色器语言转换为以前的版本？我是新手。
