安卓User固件默认开启usb调试

客户需要user固件默认开启usb调试。
要在一下两处进行修改：framework/base下的AdbService.java和UsbDebuggingActivity.java
 

AdbService.java 
public void systemReady() {
        if (DEBUG) Slog.d(TAG, "systemReady");


        /*
         * Use the normal bootmode persistent prop to maintain state of adb across
         * all boot modes.
         */
        mIsAdbUsbEnabled = containsFunction(
                SystemProperties.get(USB_PERSISTENT_CONFIG_PROPERTY, ""),
                UsbManager.USB_FUNCTION_ADB);
        boolean shouldEnableAdbUsb = mIsAdbUsbEnabled
                || SystemProperties.getBoolean(
                        TestHarnessModeService.TEST_HARNESS_MODE_PROPERTY, false);
        mIsAdbWifiEnabled = "1".equals(
                SystemProperties.get(WIFI_PERSISTENT_CONFIG_PROPERTY, "0"));

        // make sure the ADB_ENABLED setting value matches the current state

      try {
          // 强制开启adb调试
          Settings.Global.putInt(mContentResolver,
                  Settings.Global.ADB_ENABLED, 1);
          Settings.Global.putInt(mContentResolver,
                  Settings.Global.ADB_WIFI_ENABLED, mIsAdbWifiEnabled ? 1 : 0);
      } catch (SecurityException e) {
          // If UserManager.DISALLOW_DEBUGGING_FEATURES is on, that this setting can't be changed.
          Slog.d(TAG, "ADB_ENABLED is restricted.");
      }
}

UsbDebuggingActivity.java则是不进行判断弹窗后默认同意。
在onCreate里setupAlert();之前。并且要在设置key之后。不然会无法使用adb呢

UsbDebuggingActivity.java   
         notifyService(true, true); //默认同意
            finish();
