先生们好日子。通常，任务是获取应用程序执行日志并通过邮件将它们发送给开发人员。我认为发送会有问题，但日志不会有问题。有一个代码：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class GetLogs {
public static String get(){
StringBuilder builder = new StringBuilder();
try {
Process process = Runtime.getRuntime().exec("logcat -d all");
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(process.getInputStream()));
String line;
while ((line = bufferedReader.readLine()) != null) {
builder.append(line + "\n");
}
} catch (IOException e){
Log.d("Error getting logs");
}
return builder.toString();
}
}
该类只是捕获并返回日志，问题在于它捕获它们的标签。“logcat -d all”应该捕获所有带有d标签的日志，但是我手动输出的那些日志原则上不会捕获。我这样输出它（好吧，你永远不知道）：
Log.d("MyLog","TEST");
上面的方法返回以下内容：

事实上，如果您添加更多我编写的日志，这就是您所需要的。请告诉我，怎么做？
