Android开发:禁用“显示通知"以root权限编程? [英] Android development: disable "show notification" programmatically with root permission?

问题描述

有没有办法以编程方式更改应用程序的详细信息(设置 -> 应用程序 -> [anApp])?具体来说，我可以取消选中显示通知"吗?

Is there a way to programmatically change the details (Settings -> Apps -> [anApp]) of an app? Specifically, can I uncheck "show notification"?

我假设你有 root 权限

I assume that you have root permissions

推荐答案

首先，这似乎取决于您对哪个版本的 Android 感兴趣.似乎在 4.3 中情况有所改变.我正在调查最新的 master 分支(它是 l-preview)，所以我们找到了 AOSP 兔子洞......

Firstly it seems that it depends on which version of Android you are interested in. It seems that things changed in 4.3. I am investigating the latest master branch (which is l-preview), so going down the AOSP rabbit hole we find...

在设置包中...

InstalledAppDetails.java:1299

private void setNotificationsEnabled(boolean enabled) {
    String packageName = mAppEntry.info.packageName;
    INotificationManager nm = INotificationManager.Stub.asInterface(
            ServiceManager.getService(Context.NOTIFICATION_SERVICE));
    try {
        final boolean enable = mNotificationSwitch.isChecked();
        nm.setNotificationsEnabledForPackage(packageName, mAppEntry.info.uid, enabled);
    } catch (android.os.RemoteException ex) {
        mNotificationSwitch.setChecked(!enabled); // revert
    }
}

在框架/基础...

NotificationManagerService.java:454

public void setNotificationsEnabledForPackage(String pkg, int uid, boolean enabled) {
    checkCallerIsSystem();

    Slog.v(TAG, (enabled?"en":"dis") + "abling notifications for " + pkg);

    mAppOps.setMode(AppOpsManager.OP_POST_NOTIFICATION, uid, pkg,
            enabled ? AppOpsManager.MODE_ALLOWED : AppOpsManager.MODE_IGNORED);

    // Now, cancel any outstanding notifications that are part of a just-disabled app
    if (ENABLE_BLOCKED_NOTIFICATIONS && !enabled) {
        cancelAllNotificationsInt(pkg, 0, 0, true, UserHandle.getUserId(uid));
    }
}

进一步在框架/基础...

Further in frameworks/base...

base/core/java/android/app/AppOpsManager.java

124: public static final int OP_POST_NOTIFICATION = 11;

更深入的框架/基础...

Deeper in frameworks/base...

base/services/java/com/android/server/am/ActivityManagerService.java

2000: mAppOpsService = new AppOpsService(new File(systemDir, "appops.xml"));

所以如果你有 root 你可以修改 /data/system/appops.xml.您可能需要通过阅读以下代码来研究格式:https://github.com/android/platform_frameworks_base/blob/master/core/java/android/app/AppOpsManager.java

So if you have root you can modify the /data/system/appops.xml. You may need to study the format by reading the code at: https://github.com/android/platform_frameworks_base/blob/master/core/java/android/app/AppOpsManager.java

我在这里找到了一篇很长的文章，其中包含一些可能也有帮助的信息:
