是否可以从应用程序执行亚行的shell命令？ [英] Is it possible to execute ADB shell commands from app?
问题描述
我有一个 Android的PC 的是根（乱盒）连接到外部显示器（HDMI和放大器; USB）始终以横向显示，即使我的应用程序指定清单中的活动宣言画像：
I have an Android PC with root (out-of-box) connected to an external monitor (HDMI & USB) that always displays in landscape, even though my app specifies portrait in the activity declaration in Manifest:
android:screenOrientation="portrait"
我想执行此以下命令<一href="http://stackoverflow.com/questions/13381828/is-it-possible-to-execute-adb-commands-through-my-android-app">SO帖子给力纵向：
proc = Runtime.getRuntime().exec("adb shell content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:0");
int exitVal = proc.waitFor();
这应该设置在屏幕上的肖像，但显示始终保持在景观。没有例外的记录。
This should set the screen to portrait, but the display always remains in landscape. No exceptions are recorded.
我也用没有成功如下：
process = Runtime.getRuntime().exec("content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:0");
process = Runtime.getRuntime().exec(new String[]{"su","-c","content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:0"});
在这两种情况下，退出值是[0]。这意味着正常终止命令。
In both cases, the exit value is [0]. Which means the command terminated normally.
只有一个USB端口，和一个微USB端口（只功率/无数据）的机器人的PC上。如果启用了调试，我无法枚举设备DDMS，也没有从BASH执行shell命令连接我开发PC和Android的PC上的micro USB接口。所以，我想从我的Android应用程序做到这一点。
There is only one USB port, and one micro USB port (Power only/no data) on the Android PC. With debugging enabled, I cannot enumerate the device in DDMS, nor execute shell commands from BASH connecting my dev PC to the micro USB port on the Android PC. So, I am trying to do this from my Android app.
请指教
推荐答案
在设备上执行的命令，没有必要preFIX用亚行外壳 ，你的java code中的设备上运行本身所以只是把它关闭，只需要运行下面的命令
When executing a command on the device there is no need to prefix it with adb shell, your java code runs on the device itself so just drop it off and just run the following command
content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:0"
只是一个快速的音符，当你这样做，你告诉了Android设备上通过亚行连接其它Android设备执行此命令
Just a quick note, when you do so, you tell the Android device to execute this command on another android device that is connected to it via ADB
