android應用在被Google Play過濾掉的問題

突然發現我的應用程式被google play表示為不支援Google Nexus 7。。。憤怒啊！    查原因分析後發現有以下幾種可能：    1. 網路攝影機問題，Nexus7隻有自拍，所以如果應用中申請了許可權<uses-permission android:name="android.permission.CAMERA"/>的話，為了支援Nexus7需要設定過濾特性<uses-feature android:name="android.hardware.camera" android:required="false" />。    2. 如果設定了類似如下的設定的話  [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，所以可以設定為固定值即可。
