应用程序不适用于所有设备

Question

我做了一个音乐播放器应用。它在某些设备上运行正常，但在其他一些设备上崩溃。我无法理解错误。我如何解决它？我所理解的是第一个错误，那就是我必须单独获得读取 phone 状态权限的权限。

错误 1：

这是用户提交的错误。

我在清单和 Java 中都获得了 Android m 的许可，我没有使用任何写入外部存储的功能，但它也显示了这个错误。

Answer 1

您必须添加此权限

<uses-permission android:name="android.permission.READ_PHONE_STATE" />


<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

到AndroidManifest.xml 文件

Answer 2

可能是因为某些设备是运行 Android 6.0 或更高版本，而其他设备不是。

见https://developer.android.com/training/permissions/requesting.html

If the device is running Android 5.1 or lower, or your app's target SDK is 22 or lower: If you list a dangerous permission in your manifest, the user has to grant the permission when they install the app; if they do not grant the permission, the system does not install the app at all.

If the device is running Android 6.0 or higher, and your app's target SDK is 23 or higher: The app has to list the permissions in the manifest, and it must request each dangerous permission it needs while the app is running. The user can grant or deny each permission, and the app can continue to run with limited capabilities even if the user denies a permission request.

Answer 3

在 Android >=6.0 上，我们必须请求权限运行时。

第一步：在AndroidManifest.xml文件中添加

第二步：请求许可。

第三步：请求权限时处理回调。

检查这个：Permission at Run Time
