Android apps are filtered out by Google Play

Suddenly, I found my application was marked as not supporting google Nexus 7 by Google play... Angry! The Cause Analysis shows the following possibilities: 1. camera problems, Nexus7 only has a front camera, so if the application has applied for permission <uses-permission android: name = "android. permission. to support Nexus7, you need to set the filter feature <uses-feature android: name = "android. hardware. camera "android: required =" false "/>. 2. if the following settings are set, [html] <compatible-screens> <screen android: screenSize = "normal" android: screenDensity = "mdpi"/> <screen android: screenSize = "normal" android: screenDensity = "hdpi"/> <screen android: screenSize = "normal" android: screenDensity = "xhdpi"/> <screen android: screenSize = "large" android: screenDensity = "ldpi"/> <screen android: screenSize = "large" android: screenDensity = "mdpi"/> <screen android: scre EnSize = "large" android: screenDensity = "hdpi"/> <screen android: screenSize = "large" android: screenDensity = "xhdpi"/> <screen android: screenSize = "xlarge" android: screenDensity = "ldpi"/> <screen android: screenSize = "xlarge" android: screenDensity = "mdpi"/> <screen android: screenSize = "xlarge" android: screenDensity = "hdpi"/> <screen android: screenSize = "xlarge" android: screenDensity = "xhdpi"/> </compatible-scree Ns> <compatible-screens> <screen android: screenSize = "normal" android: screenDensity = "mdpi"/> <screen android: screenSize = "normal" android: screenDensity = "hdpi"/> <screen android: screenSize = "normal" android: screenDensity = "xhdpi"/> <screen android: screenSize = "large" android: screenDensity = "ldpi"/> <screen android: screenSize = "large" android: screenDensity = "mdpi"/> <screen android: screenSize = "large" androi D: screenDensity = "hdpi"/> <screen android: screenSize = "large" android: screenDensity = "xhdpi"/> <screen android: screenSize = "xlarge" android: screenDensity = "ldpi"/> <screen android: screenSize = "xlarge" android: screenDensity = "mdpi"/> <screen android: screenSize = "xlarge" android: screenDensity = "hdpi"/> <screen android: screenSize = "xlarge" android: screenDensity = "xhdpi"/> </compatible-screens> because the dpi of N7 is not listed above, So it is filtered out, and the dpi value of N7 is 213, so you can set it to a fixed value.
