JAVAlang.SecurityException:权限拒绝：启动意图{act=安卓.settings.USAGE_ACCESS_settings}

Question

我懂java。lang.SecurityException当试图以final Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);意图startActivityForResult(intent, requestCode);时。有趣的是，这种崩溃只发生在Android 5.1-5.1.1的华为上 我没有华为设备。你能给我一些建议吗

Answer 1

根据android开发者文档

In some cases, a matching Activity may not exist, so ensure you safeguard against this.

链接：ACTION_USAGE_ACCESS_SETTINGS

Answer 2

无论出于何种原因，华为为这项活动保留了<intent-filter>，但他们将其标记为未出口。你不可能开始这项活动。你所能做的就是捕捉异常并向用户解释你无法在那里导航
