我的Android應用支持0個設備

Question

這是我的清單文件。 我在stackoverflow上找到了許多其他答案，但是沒有人適合我。 我現在還在我的清單文件中添加了屏幕大小，但還沒有完全顯示。 我多次檢查所有許可，對我來說還不錯。 請幫忙！

Answer 1

我認為您的答案在這里：

<uses-sdk
        android:minSdkVersion="19"
        android:targetSdkVersion="22" />

您應該以程序將支持的最低限度為目標。 19/22很高。

Answer 2

更改

<uses-feature android:name="android.hardware.camera">

至

<uses-feature android:name="android.hardware.camera" android:required="false"/>

如果您未指定android：required屬性，則默認為“ true”。 因此，除非存在相機硬件，否則Google Play商店將假定該應用程序將無法運行。

如下所示將android：required設置為false后，Play商店將接受APK並顯示可用於該應用程序的設備列表。

您可能還會在功能描述符上尋找拼寫錯誤。 有關受支持的功能描述符的信息，請參見http://developer.android.com/guide/topics/manifest/uses-feature-element.html#features-reference
