遇到问题描述:

运行android程序控制台输出

 The connection to adb is down, and a severe error has occured.
 You must restart adb and Eclipse.
 Please ensure that adb is correctly located at 'D:\java\sdk\platform-tools\adb.exe' and can be executed.

发现adb 启动不了。之前一直都好好,所有环境应该是没问题,那应该就是有冲突或什么的了。
网上很多都说kill 掉adb 然后重启,但是我发现adb根本就没有启动。

解决方法:
1.于是查看了下adb的默认端口5037 是否被其他应用占用:
cmd
netstat -aon|findstr "5037"

TCP    127.0.0.1:5037         0.0.0.0:0              LISTENING       1292
果然被占用了
2.查看下是被哪个进程占用:
tasklist|findstr "1292"

tadb.exe                    1292 Console                 0      3,564 K

             发现被tadb.exe占用tadb.exe 是腾讯的连接安卓设备的驱动进程 果断结束掉,并删除

3.重启eclipse

发现还是不行???????

4.再次按以上步骤查看
发现5037端口又被360手机助手占用惊恐,这尼玛的。。。比土匪还土匪
果断删除

5.再次重启eclipse
终于一切恢复正常。。。。高高兴兴的coding.....

以上可能并不适合所有人,只是本人解决的一个记录,如果有什么其他解决办法还请多指教



### ADB Drag-and-Drop Permission Issue When dealing with Android Debug Bridge (ADB) drag-and-drop operations, permissions play a critical role in ensuring that the application can interact correctly with external components or devices. For instance, when an app needs to handle specific administrative tasks such as network logging and certificate selection, it must declare appropriate receivers within its manifest file[^1]. This ensures that only authorized applications are allowed to bind to these services. To address potential issues related to `adb` drag-and-drop functionality involving permissions: #### Manifest Declaration Applications requiring delegated admin capabilities should define their broadcast receiver properly by specifying actions like `NETWORK_LOGS_AVAILABLE` and `CHOOSE_PRIVATE_KEY_ALIAS`. These declarations ensure proper intent filtering while also enforcing necessary security constraints through permissions such as `BIND_DELEGATED_ADMIN`. ```xml <receiver android:name=".app.DelegatedAdminReceiver" android:permission="android.permission.BIND_DELEGATED_ADMIN"> <intent-filter> <action android:name="android.app.admin.action.NETWORK_LOGS_AVAILABLE"/> <action android:name="android.app.action.CHOOSE_PRIVATE_KEY_ALIAS"/> </intent-filter> </receiver> ``` This configuration restricts access solely to those entities holding the specified permission level[^1]. #### Handling Permissions Programmatically Beyond static configurations via XML files, dynamic handling may sometimes be required depending upon use cases. Ensure all relevant runtime checks occur before performing sensitive activities over adb connections. Although primarily focused around gaming engines rather than direct mobile development tools per se, certain principles remain applicable across domains including robustness enhancements introduced since versions akin to Unity's milestone update where numerous architectural changes were implemented enhancing overall stability alongside introducing novel functionalities[^2]: For example, consider implementing logic similar below which verifies granted consents prior executing commands potentially affecting user privacy settings etcetera : ```java if(ContextCompat.checkSelfPermission(context,Manifest.permission.YOUR_PERMISSION)==PackageManager.PERMISSION_GRANTED){ // Proceed safely knowing we have explicit approval from end-user regarding requested capability. }else{ ActivityCompat.requestPermissions((Activity)context,new String[]{Manifest.permission.YOUR_PERMISSION},REQUEST_CODE); } ``` Such approaches help mitigate risks associated unauthorized accesses during automated processes executed remotely using command-line utilities provided under Android SDK suite . ---
