Android 11.0 默认开启USB调试功能

近来收到项目反馈需求想要默认开启USB调试功能，默认开启USB调试功能主要是在UsbDebuggingActivity.java文件中实现，具体修改参照如下：

/vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/usb/UsbDebuggingActivity.java

        public void onReceive(Context content, Intent intent) {String action = intent.getAction();if (!UsbManager.ACTION_USB_STATE.equals(action)) {return;}
-            boolean connected = intent.getBooleanExtra(UsbManager.USB_CONNECTED, false);
+            boolean connected = false;
+            if (!connected) {
+                mActivity.finish();
+            }
+   	   try {
+		 IBinder b = ServiceManager.getService(ADB_SERVICE);
+		 IAdbManager service = IAdbManager.Stub.asInterface(b);
+		 service.allowDebugging(true, mKey);
+		 } catch (Exception e) {
+		 	Log.e(TAG, "Unable to notify Usb service", e);
+			 }}

默认开启USB调试功能的话，USB调试的权限申请弹窗自然也要去掉，去掉弹窗并默认赋予权限是在UsbPermissionActivity.java文件中修改，具体修改参照如下：

/vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/usb/UsbPermissionActivity.java
 

            mAlwaysUse.setOnCheckedChangeListener(this);mClearDefaultHint = (TextView)ap.mView.findViewById(com.android.internal.R.id.clearDefaultHint);mClearDefaultHint.setVisibility(View.GONE);}-        setupAlert();
+        mPermissionGranted = true;
+        finish();}

重新编译验证，修改生效，已默认开启USB调试功能
