如何讓我的Android應用僅適用於手機？

Question

我的應用專爲手機設計，但是當我嘗試將應用上傳到市場時，它顯示我的應用對平板電腦（xlarge）也可見。如果從平板電腦訪問，我故意不希望我的應用在市場上展示。

我試着玩minSdkVersion和targetVersion支持和元素。

我也使用

<manifest ... > 
    <compatible-screens> 
     <!-- all small size screens --> 
     <screen android:screenSize="small" android:screenDensity="ldpi" /> 
     <screen android:screenSize="small" android:screenDensity="mdpi" /> 
     <screen android:screenSize="small" android:screenDensity="hdpi" /> 
     <screen android:screenSize="small" android:screenDensity="xhdpi" /> 
     <!-- all normal size screens --> 
     <screen android:screenSize="normal" android:screenDensity="ldpi" /> 
     <screen android:screenSize="normal" android:screenDensity="mdpi" /> 
     <screen android:screenSize="normal" android:screenDensity="hdpi" /> 
     <screen android:screenSize="normal" android:screenDensity="xhdpi" /> 
    </compatible-screens> 
    ... 
    <application ... > 
     ... 
    <application> 
</manifest> 

嘗試，但我得到一個錯誤：

Multiple annotations found at this line:
- error: No resource identifier found for attribute 'screenDensity' in package
'android'
- error: No resource identifier found for attribute 'screenSize' in package
'android'

我缺少什麼？

Answer 1

您應該使用market filters來指定您的應用程序確實需要的那些東西。如果設備需要爲手機，請添加<uses-feature android:name="android.hardware.telephony"/>

通過指定兼容屏幕尺寸來過濾平板電腦是沒有意義的。有關硬件功能列表，請參見<uses-feature>。不要僅僅爲了過濾而添加元素，清單應該指定應用程序爲了工作而需要的內容。

如何使用<supports-screens>標籤？

<manifest ... > 
    <supports-screens android:smallScreens="true" 
         android:normalScreens="true" 
         android:largeScreens="true" 
         android:xlargeScreens="false" 
         android:largestWidthLimitDp="600" /> 
    <application> 
    </application> 
</manifest>

我真的不知道這是否是去了解它的正確方法。但是，我遇到過這種情況，並將其用於我的應用中，以確保平板電腦用戶無法在其設備上訪問此應用。

//verify the android version running on the phone/device 
int currentDeviceVersion = android.os.Build.VERSION.SDK_INT; 

//since tablets would be running HoneyComb or higher 
if (currentDeviceVersion >= android.os.Build.VERSION_CODES.HONEYCOMB){ 
    // display message that app is not supported for android honeycomb and above 
    // End (finish) app 
}

通過查看播放控制檯的設備目錄，您需要指定更多的screenDensity值。 （見下文，截至今日）我認爲在設備目錄中總會看到新值出現的風險。所以你應該不斷監測你的應用不支持的設備數量。

<!-- Exclude Tablets --> 
<compatible-screens> 
    <!-- all small size screens --> 
    <screen android:screenSize="small" android:screenDensity="ldpi" /> 
    <screen android:screenSize="small" android:screenDensity="mdpi" /> 
    <screen android:screenSize="small" android:screenDensity="hdpi" /> 
    <screen android:screenSize="small" android:screenDensity="xhdpi" /> 
    <screen android:screenSize="small" android:screenDensity="xxhdpi" /> 
    <screen android:screenSize="small" android:screenDensity="xxxhdpi" /> 
    <screen android:screenSize="small" android:screenDensity="213" /> 
    <screen android:screenSize="small" android:screenDensity="280" /> 
    <screen android:screenSize="small" android:screenDensity="360" /> 
    <screen android:screenSize="small" android:screenDensity="400" /> 
    <screen android:screenSize="small" android:screenDensity="420" /> 
    <screen android:screenSize="small" android:screenDensity="480" /> 
    <screen android:screenSize="small" android:screenDensity="560" /> 
    <!-- all normal size screens --> 
    <screen android:screenSize="normal" android:screenDensity="ldpi" /> 
    <screen android:screenSize="normal" android:screenDensity="mdpi" /> 
    <screen android:screenSize="normal" android:screenDensity="hdpi" /> 
    <screen android:screenSize="normal" android:screenDensity="xhdpi" /> 
    <screen android:screenSize="normal" android:screenDensity="xxhdpi" /> 
    <screen android:screenSize="normal" android:screenDensity="xxxhdpi" /> 
    <screen android:screenSize="normal" android:screenDensity="213" /> 
    <screen android:screenSize="normal" android:screenDensity="280" /> 
    <screen android:screenSize="normal" android:screenDensity="360" /> 
    <screen android:screenSize="normal" android:screenDensity="400" /> 
    <screen android:screenSize="normal" android:screenDensity="420" /> 
    <screen android:screenSize="normal" android:screenDensity="480" /> 
    <screen android:screenSize="normal" android:screenDensity="560" /> 
</compatible-screens>
