android應用在被Google Play過濾掉的問題

突然發現我的應用被google play表示為不支持Google Nexus 7。。。憤怒啊！         查原因分析後發現有以下幾種可能：         1. 攝像頭問題，Nexus7只有前置攝像頭，所以如果應用中申請了權限<uses-permission android:name="android.permission.CAMERA"/>的話，為了支持Nexus7需要設置過濾特性<uses-feature android:name="android.hardware.camera" android:required="false" />。         2. 如果設置了類似如下的設置的話     [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:screenSize="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-screens>     <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" 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-screens>     因為N7的dpi不是上面所列出的項，所以被過濾掉了，而N7的dpi值應該是213，所以可以設置為固定值即可。
