无法通过Android M的代码设置铃声
无法通过Android M的代码设置铃声
提问于 2017-11-11 12:05:18
我正在开发一个应用程序，将从用户已经选择的铃声列表随机设置铃声。
虽然我的代码可以在Android N和更高版本上运行，但我在Android M和更低版本上遇到了问题。我已经搜索了很多次来寻找解决方案。但是找不到。
下面是我设置铃声的代码片段。
RingtoneManager.setActualDefaultRingtoneUri(getApplicationContext(),
RingtoneManager.TYPE_RINGTONE,
uri);这是我的清单文件。
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
以下是应用程序运行时生成的错误日志

我已经搜索了如何获得android.permission.MANAGE_DOCUMENTS权限。我收集到的是它的安全级别是signature，只有安卓自带的应用程序才能拥有该权限。

请在此处正确检查您的错误。我可以看到requires android.permission.MANAGE_DOCUMENTS or android.permission.MANAGE_DOCUMENTS，而且您必须使用运行时权限才能获得这些权限
