需要提示MIUI用户开启某些权限，因此需要跳转其权限编辑页面

网上基本只有比较古老的MIUI5/6的跳转方式：

Intent localIntent = new Intent("miui.intent.action.APP_PERM_EDITOR");
localIntent.setClassName("com.miui.securitycenter", "com.miui.permcenter.permissions.AppPermissionsEditorActivity");
localIntent.putExtra("extra_pkgname", context.getPackageName());
context.startActivity(localIntent);

这种方式已经不能满足如今的新版MIUI 8，所以，自己动手丰衣足食

电脑打开cmd/terminal， 手机打开应用权限设置页面：

命令行输入：

adb shell dumpsys activity | grep "mFocusedActivity"

输入结果：

mFocusedActivity: ActivityRecord{11ae2ef u0 com.miui.securitycenter/com.miui.permcenter.permissions.PermissionsEditorActivity t192}

即为当前打开的权限设置页的Activity

观察到Activity包名与MIUI 5/6的相同，Activity名字不同，将跳转代码改为：

// MIUI 8
Intent localIntent = new Intent("miui.intent.action.APP_PERM_EDITOR");
localIntent.setClassName("com.miui.securitycenter", "com.miui.permcenter.permissions.PermissionsEditorActivity");
localIntent.putExtra("extra_pkgname", context.getPackageName());
context.startActivity(localIntent);

成功跳转。

完整的工具类如下：

public class MiuiUtils {
    /**
     * 跳转到MIUI应用权限设置页面
     *
     * @param context context
     */
    public static void jumpToPermissionsEditorActivity(Context context) {
        if (isMIUI()) {
            try {
                // MIUI 8
                Intent localIntent = new Intent("miui.intent.action.APP_PERM_EDITOR");
                localIntent.setClassName("com.miui.securitycenter", "com.miui.permcenter.permissions.PermissionsEditorActivity");
                localIntent.putExtra("extra_pkgname", context.getPackageName());
                context.startActivity(localIntent);
            } catch (Exception e) {
                try {
                    // MIUI 5/6/7
                    Intent localIntent = new Intent("miui.intent.action.APP_PERM_EDITOR");
                    localIntent.setClassName("com.miui.securitycenter", "com.miui.permcenter.permissions.AppPermissionsEditorActivity");
                    localIntent.putExtra("extra_pkgname", context.getPackageName());
                    context.startActivity(localIntent);
                } catch (Exception e1) {
                    // 否则跳转到应用详情 
                    Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                    Uri uri = Uri.fromParts("package", context.getPackageName(), null);
                    intent.setData(uri);
                    context.startActivity(intent);
                }
            }
        }
    }


    /**
     * 判断是否是MIUI
     */
    private static boolean isMIUI() {
        String device = Build.MANUFACTURER;
        if (device.equals("Xiaomi")) {
            try {
                Properties prop = new Properties();
                prop.load(new FileInputStream(new File(Environment.getRootDirectory(), "build.prop")));
                return prop.getProperty("ro.miui.ui.version.code", null) != null
                        || prop.getProperty("ro.miui.ui.version.name", null) != null
                        || prop.getProperty("ro.miui.internal.storage", null) != null;
            } catch (IOException e) {
                e.printStackTrace();
            }

        }
        return false;
    }
}
