任何人都可以告诉我如何振动相同的模式5次像我的模式

long[] pattern = { 0, 200, 500 };

我希望这种模式重复5次

Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(pattern , 5);

我试图将印地语字符粘贴在一个数组中,
String[] arr = {"???? ?????? ??","???? ?????? ??"};
但是它给出了错误,即
"some characters cannot be mapped using "Cp1252" character encoding"
保存时.

我正在尝试在Android中集成Log4j2,但收到以下错误消息:

java.lang.ClassCastException: org.apache.logging.log4j.simple.SimpleLoggerContext cannot be cast to org.apache.logging.log4j.core.LoggerContext

import org.apache.logging.log4j.Level;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.core.Logger;
import org.apache.logging.log4j.core.LoggerContext;
import org.apache.logging.log4j.core.appender.SyslogAppender;

  LoggerContext context = (LoggerContext) LogManager.getContext();
  Logger root = context.getLogger("MainActivity");
  SyslogAppender appender = obtainAppender();

  if (!appender.isStarted()) 
    appender.start();

  root.addAppender(appender);
  root.setAdditive(false);
  root.setLevel(Level.DEBUG);
  root.debug("This is a test message");

我正在寻找一种解决方案来获取具有纬度、经度和速度参数的设备的位置。解决方案应该适用于 Android OS 8 和更低版本。
