Looking to enable and disable (toggle) ADB or USB debugging using command line or in app
提问by Chris
I'm trying to enable ADB (USB debugging) only when my application is running and disabling it when my application is not. I have full access to the phone and it is rooted, suavailable, etc., but I cannot find a way to do the toggling.
我试图仅在我的应用程序正在运行时启用 ADB（USB 调试），并在我的应用程序未运行时禁用它。我可以完全访问手机，并且它已植根、su可用等，但我找不到进行切换的方法。
What I've tried so far:
到目前为止我尝试过的：
Process proc = Runtime.getRuntime().exec(new String [] { "su", "-c", "setprop", "persist.service.adb.enable", "0"});
proc.waitFor();
Process proc2 = Runtime.getRuntime().exec(new String [] { "su", "-c", "stop", "adbd"});
proc2.waitFor();
This however causes the phone to enter a reboot loop instantaneously.
然而，这会导致手机立即进入重启循环。

The code that works is easy:
有效的代码很简单：
Settings.Secure.putInt(getContentResolver(),Settings.Secure.ADB_ENABLED, 0); // 0 to disable, 1 to enable
Edit/Update: Thanks to @MohanT for the following update:
编辑/更新：感谢@MohanT 的以下更新：
Settings.Global.putInt(getContentResolver(),Settings.Global.ADB_ENABLED, 0); // 0 to disable, 1 to enable
However, the app needs to be a system app to be able to use this. To get out of having to sign it, build a custom rom, etc.. I did the following to get it to be a system app.
但是，该应用程序必须是系统应用程序才能使用它。为了摆脱签名，构建自定义 rom 等。我执行了以下操作以使其成为系统应用程序。
First, I installed it regularly using eclipse, then adb shell:
首先，我使用 eclipse 定期安装它，然后使用 adb shell：
> su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# cat /data/app/filename.apk > /system/app/filename.apk
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
# reboot

You can achieve by following next steps:
您可以通过以下步骤实现：
Check whether ADB is currently enabled. To do that you can use a relevant global constant:
Settings.Global.ADB_ENABLEDfor API 17 and above.Settings.Secure.ADB_ENABLEDprior to API 17.
Use implicit
IntentwithSettings.ACTION_APPLICATION_DEVELOPMENT_SETTINGSaction to open developers options, where user can enable or disable ADB.
检查当前是否启用了 ADB。为此，您可以使用相关的全局常量：
Settings.Global.ADB_ENABLED适用于 API 17 及更高版本。Settings.Secure.ADB_ENABLED在 API 17 之前。
使用implicit
IntentwithSettings.ACTION_APPLICATION_DEVELOPMENT_SETTINGSaction 打开开发人员选项，用户可以在其中启用或禁用ADB。
Code example:
代码示例：
Java
爪哇
public static final int API = Build.VERSION.SDK_INT;
public static final int ENABLED=1, DISABLED=0;
public static boolean adbEnabled(Context context){
if(API>16)
return ENABLED == Settings.Global.getInt(context.getContentResolver(), Settings.Global.ADB_ENABLED,DISABLED);
else
return ENABLED == Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.ADB_ENABLED,DISABLED);
}
public void checkAdb(Context context){
//if ADB disabled
if(!adbEnabled(context)){
//open developer options settings
Intent intent = new Intent(Settings.ACTION_APPLICATION_DEVELOPMENT_SETTINGS);
context.startActivity(intent);
}
}
Kotlin
科特林
val API = Build.VERSION.SDK_INT
val ENABLED = 1
val DISABLED = 0
fun adbEnabled(context: Context): Boolean {
return if (API > 16)
ENABLED == Settings.Global.getInt(context.contentResolver, Settings.Global.ADB_ENABLED, DISABLED)
else
ENABLED == Settings.Secure.getInt(context.contentResolver, Settings.Secure.ADB_ENABLED, DISABLED)
}
fun checkAdb(context: Context) {
//if ADB disabled
if (!adbEnabled(context)) {
//open developer options settings
val intent = Intent(Settings.ACTION_APPLICATION_DEVELOPMENT_SETTINGS)
context.startActivity(intent)
}
}
Just for reference:
Prior to API 3 (probably no longer relevant)
Settings.System.ADB_ENABLEDwas used.
仅供参考：
在 API 3（可能不再相关）
Settings.System.ADB_ENABLED之前使用。

Chris's answer is correct except the ADB_ENABLED field in Secure class has been depreciated and the string has been moved to Global class. So you can use below command -
Chris 的回答是正确的，只是 Secure 类中的 ADB_ENABLED 字段已折旧并且字符串已移至 Global 类。所以你可以使用下面的命令 -
Settings.Global.putInt(getContentResolver(),Settings.Global.ADB_ENABLED, 0); // 0 to disable, 1 to enable

From my experiences using setprop doesn't always work reliable, and might even conflict with the Settings > Applications > Development > USB Debugging option. Besides that it might be irritating for instance if USB debugging is enabled but adb doesn't work etc. Therefore using Settings.Secure.ADB_ENABLED is the prefered way... plus you always have the notification in the status panel.
根据我使用 setprop 的经验，它并不总是可靠的，甚至可能与 Settings > Applications > Development > USB Debugging 选项冲突。除此之外，如果启用了 USB 调试但 adb 不起作用等，它可能会令人恼火。因此，使用 Settings.Secure.ADB_ENABLED 是首选方式......此外，您总是在状态面板中收到通知。
If you don't want to go through the hassle to install your app on system partition when only trying to access Settings.Secure.ADB_ENABLED then you can instead rely on another app that is doing this work already:
如果您不想在仅尝试访问 Settings.Secure.ADB_ENABLED 时在系统分区上安装应用程序的麻烦，那么您可以依赖另一个已经在执行此工作的应用程序：
This app is called ADB Toggle. You can find it in Google Play:
