我使用像素与最新的Android 8.1.0更新.

我正面临与BLE广告扫描有关的问题.每当我关闭屏幕(即按下电源按钮)时,我的扫描将停止.它会在打开屏幕后立即重启.

我查看了BLE的最新代码.谷歌新推出此功能(参考链接).

有没有办法跳过这部分,我的意思是扫描不应该停止,无论屏幕打开或关闭.

最近我用build工具和apis更新了android studio.

在同步当前项目时,我收到的错误如下:"错误配置'compile'已过时,已被'implementation和'api'替换.如何修复此错误.

I am using MI note 4(Android 7.0) and Moto x play (Android 7.1.1)

I am doing BLE scan in sperate service. While scanning I am getting scan response as "scan failed" Turning ON/OFF Bluetooth is not affecting in scan response. Turning ON/OFF Wifi is also not affecting in scan response.

(But in this case android inbuilt(from Settings->Bluetooth) Bluetooth scanning was working fine).

I used BLE scanner app also but that app is also not detecting BLE advertisement!

I tried with …

我正在使用以下代码在存储中创建目录/文件。

   File file  = new File(Environment.getExternalStorageDirectory().toString(), "/MyDirectory");

在 android 10 中更新目标 SDK 版本 29 后，它无法正常工作。

谁能建议如何在应用程序范围之外创建文件夹？

我进行了搜索，但没有得到任何答案。当我们的手机连接到Android Auto时，是否可以检测到任何广播？

我有这段代码，但是需要通过某些事件来运行。

public static boolean isCarUiMode(Context c) {
UiModeManager uiModeManager = (UiModeManager) c.getSystemService(Context.UI_MODE_SERVICE);
if (uiModeManager.getCurrentModeType() == Configuration.UI_MODE_TYPE_CAR) {
    LogHelper.d(TAG, "Running in Car mode");
    return true;
} else {
    LogHelper.d(TAG, "Running on a non-Car mode");
    return false;
}
