BroadcastReceiver的权限亚行外壳

问题描述

考虑使用广播接收器来实现一个简单的目标的简单工具。因为这不应该被其他应用程序使用，它定义与签名或 signatureOrSystem A的ProtectionLevel权限：

Consider a simple tool using a BroadcastReceiver to achieve a simple goal. Because this should not be used by other applications, it defines a permission with a protectionLevel of signature or signatureOrSystem:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="any.test">

    <permission
        android:name="any.test.PERMISSION"
        android:protectionLevel="signatureOrSystem" />

    <application android:label="AnyTest">
        <receiver
            android:name=".Receiver"
            android:exported="true"
            android:permission="any.test.PERMISSION" />
    </application>
</manifest>

现在我想用通过

adb shell am broadcast -n any.test/.Receiver

从我的计算机。虽然这个工程在模拟器上完全没有问题，它不会在所有的真实设备上时，这个权限设置工作。如果没有设置权限，一切都按预期。

from my computer. While this works perfectly fine on an emulator, it doesn't work at all on a real device when this permission is set. If the permission is not set, everything works as intended.

所以，我怎么可以定义或授予这样我就可以用 ADB测试这一切在真实设备上的权限？

So how can I define or grant the permission so that I can test all this on a real device with ADB?

我想使这个出口接收器一点在调试模式下更安全，因此，如果有一个为亚行特别批准使用或运行时测试只允许通话从亚行我可以在 Receiver.onReceive执行（上下文，意图），这将有助于太。接收器不必为亚行，并在同一时间其他应用工作。

I want to make this exported receiver a little more secure in debug mode, so if there's a special permission for ADB usage or a run-time test to only allow calls from ADB I can implement in Receiver.onReceive(Context, Intent), it would help too. The receiver doesn't have to work for ADB and other apps at the same time.

推荐答案

一个root的shell可以发送任何权限保护的任何广播。结果
一个正常的外壳也已获得很多的权限，检查AOSP源集code这个文件：框架\\基地\\包\\壳牌\\ AndroidManifest.xml中。

A root shell can send any broadcast protected by any permissions.
A normal shell also has been granted lots of permissions, check this file in the AOSP souce code: frameworks\base\packages\Shell\AndroidManifest.xml.

替换您的 any.test.PERMISSION 在此文件中的ProtectionLevel是 signatureOrSystem ，像 android.permission.REAL_GET_TASKS 。在此之后，您可以发送广播接收这个壳，但其他3应用程序不能。

Replace your any.test.PERMISSION with one permission in this file that the protectionLevel is signatureOrSystem, like android.permission.REAL_GET_TASKS. After that, you can send broadcast to this receiver in shell, but other 3rd app can not.
