＆＃34;您无法更改私人安全设置＆＃34; - 如何在Android 6中切换铃声振动？

Question

由于Android 6 Marshmallow最近有关权限的更改，以下代码不再有效并引发异常。

Settings.System.putInt(getContentResolver(), "vibrate_when_ringing", 0);

即使在向应用授予WRITE_SETTINGS权限后，也会发生这种情况：

Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
Uri uri = Uri.fromParts("package", getActivity().getPackageName(), null);
intent.setData(uri);
startActivityForResult(intent, WRITE_SETTINGS_PERMISSION_REQUEST_CODE);
//at this point Settings activity is opened and user is prompted for permission

...

if (Settings.System.canWrite(this)) { //now returns true, because permissions were granted
    Settings.System.putInt(getContentResolver(), "vibrate_when_ringing", 0); //still crashes
} else {
    Log.w(LOG_TAG, "No permission to write settings.");
}

如何在Android 6中更改铃声振动设置（以及类似的安全设置）？

Answer 1

因为安全

众所周知，在Android 6.0（Marshmallow）中，Android添加了许多策略来控制 SECURITY ，提升效率 如：

• 运行时权限
• 打盹模式（电源管理器）
• 重写设置提供商 see details
  • 将系统设置从db移至xml
  • /data/data/com.android.providers.settings /../ settings.db - ＆gt; /数据/系统/用户/用户ID / settings_ [系统|全球|安全]的.xml

所以现在（在API 22之后）

• 您可以不写一些私密/危险设置
• 您必须在移植到API级别22或更高版本期间处理某些 EXCEPTION 。 see details
