小编Blu*_*ift的帖子

在我拥有的Android项目中,我在build.gradle文件中有这个部分:

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 19;
    }
}

在'minSdkVersion'和'targetSdkVersion'属性中,有警告:

'minSdkVersion' cannot be applied to '(java.lang.Integer)'

'targetSdkVersion' cannot be applied to '(java.lang.Integer)`

这是一个错误,还是其他什么？

此脚本将按预期运行并在Python 2.6中无任何错误地传递doctests:

def num_even_digits(n):
    """
      >>> num_even_digits(123456)
      3
      >>> num_even_digits(2468)
      4
      >>> num_even_digits(1357)
      0
      >>> num_even_digits(2)
      1
      >>> num_even_digits(20)
      2
    """


    count = 0
    while n:
        digit=n%10
        if digit%2==0:
            count+=1
            n/=10
        else:
            n/=10

    return count



if __name__ == '__main__':
    import doctest
    doctest.testmod()

在Python3.0中,这是输出:

Redis 服务器使用 Homebrew 成功运行brew services start redis。PECL Redis 安装程序似乎可以与 一起使用sudo pecl install redis ，并提供以下输出：

Build process completed successfully
Installing '/opt/homebrew/Cellar/php@7.4/7.4.28/pecl/20190902/redis.so'
install ok: channel://pecl.php.net/redis-5.3.7
Extension redis enabled in php.ini

如果我使用php --ini，这就是输出：

我致电时使用YouTube API:

new DownloadImageTask(activity, i, notificationDetails).execute(notificationDetails.get(i).getThumbUri())

这个班级:

public class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {

private int currentIndex;
private LoginActivity activity;
private ArrayList<VideoData> notifyDetails;
private String urlDisplay;

public DownloadImageTask(LoginActivity activity, int notificationDetailsIndex, ArrayList<VideoData> notificationDetails){
    currentIndex = notificationDetailsIndex;
    this.activity = activity;
    this.notifyDetails = notificationDetails;
}

@Override
protected Bitmap doInBackground(String... urls){
        urlDisplay = urls[0];           
        Bitmap image = null;
        InputStream in = null;

        try{
            in = new java.net.URL(urlDisplay).openStream();
            image = BitmapFactory.decodeStream(in);
        } catch(Exception e){
            Log.e("Error decoding bitmap", Log.getStackTraceString(e));
