在Android 5.0.1_r1中将意图从C ++发送到Java [英] Sending an intent from c++ to java in Android 5.0.1_r1

问题描述

浏览了几篇文章后，我发现我可以使用以下代码行(用于调试的第二行)发送意图:

After going through several posts I figured out I could send the intent with the following line of code (second line used for debugging):

int ret = system("am broadcast -a android.intent.action.MIKE_ACCESSED --user 0"); 

__android_log_print(ANDROID_LOG_DEBUG, "gxp18", "Shell command returned %i", ret);

不幸的是，这总是返回(无论系统中使用的命令是什么("...")):

Unfortunately, this returns always (No matter what is the command used in the system("...")):

Shell命令返回了32512

有趣的是，我可以使用以下命令通过adb成功发送意图:

Interestingly, I can successfully send the intent through adb using:

adb shell am broadcast -a android.intent.action.MIKE_ACCESSED

注意！我没有使用NDK.我在文章中报告的那段代码是对Android Framework中一部分代码的修改.特别是，它是Android服务之一的一部分.我正在使用AOSP并修改部分源代码.

Notice! I am not using NDK. The piece of code I reported in the post is a modification of a portion of code in the Android Framework. In particular, it is part of one of the Android services. I am working with the AOSP and modifying part of the source code.

推荐答案

1)禁用SELinux(设置为允许"模式) 2)修改ActivityManagerNative.java以绕过userId检查

1) Disable SELinux (Set in Permissive mode) 2) Modify ActivityManagerNative.java to bypass userId check

享受:)
