I need to check dynamically if the used device supports openGL ES 2.0. How can i do that?
Yes. The following code will do the trick:
final ActivityManager activityManager =
(ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
final ConfigurationInfo configurationInfo =
activityManager.getDeviceConfigurationInfo();
final boolean supportsEs2 = configurationInfo.reqGlEsVersion >= 0x20000;

You may also require want to restrict devices that don't support 2.0 from seeing your app in the marketplace by adding the following to your manifest:
<uses-feature android:glEsVersion="0x00020000" android:required="true" />
