android关于华为启动app出现停止运行问题

java.lang.SecurityException: Permission Denial: reading com.huawei.android.launcher.LauncherProvider from pid=30376, uid=10086 requires com.huawei.android.launcher.permission.WRITE_SETTINGS: uid 10086 does not have com.huawei.android.launcher.permission.WRITE_SETTINGS.
安装完app一打开就会报这个错,我已经添加过权限了啊 为什么没有生效呢,请帮帮忙,真的很紧急
