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;

}

}
